5.65 S o (%)

A hot dip galvanized coating, minimum average coating mass of 300 g/m2 is applied to both the external and internal surfaces. The HDG coating is applied in accordance with AS/NZS 4792 :Hot-dip galvanized (zinc) coatings on ferrous hollow sections, applied by a continuous or specialised process.

Red Painted

A smooth, even coat of a red, general purpose paint is applied to the external surface to act as a temporary rust preventative. The paint coating is 6 to12 microns DFT. This temporary coating should be removed prior to powder-coating or the application of coating systems intended for corrosion protection or architectural finishes. It is easily removed with any of the commercially available solvent based paint strippers, also usually removed as part of the available pre-treatment (caustic bath) system used in the batch hot dip galvanizing process. The resultant steel surface from the manufacturing process prior to the red paint being applied is of better appearance than AS1627.4 Class 1. OneSteel strongly recommends that you check with your coatings manufacturer or supplier whether any additional surface preparation may need to be carried out on the pipe surface, prior to the application of any paint primers, top coats or special finishes.

Black (Clear Coat)

A smooth, even coat of clear polymer is applied to the external surface. This coating is meant to act as a temporary rust preventative. It is easily removed with any of the commercially available solvent based paint strippers, and is normally removed prior to galvanizing as part of the available pre-treatments (caustic bath) used in the batch hot dip galvanizing process.

BENDING

Here are some guidelines on bending of CHS, SHS, RHS and profiles (angles, channels and flats). Best results are dependent upon the type of equipment, the quality of the formers, the centreline radius, the speed of bending and the thickness of member.

DuraGal is readily weldable. Its thin evenly applied galvanized coating ensures minimal welding fumes. However, the ventilation recommendations given in Table 17.2 of Technical Note 7 published by WTIA (Welding Technology Institute of Australia), July 1994 should be observed. Mechanical dilution ventilation is advised for open work space and mechanical ventilation by local exhaust system for limited work space and confined space. DuraGal's carbon equivalent of less than 0.39 allows it to be welded in accordance with AS/NZS 1554.1 Welding of Steel Structures, without preheat. The following are recommended consumables:

Process Manual Metal-Arc (AS 1553.1) Submerged Arc (AS 1858.1) Flux-Cored Arc (AS 2203.1) Gas Metal-Arc (AS 2717.1) Recommended Consumables E48XX (Grade 2) W502Y W502X.X W502

Draw Bending Using an Internal Mandrel - CHS, SHS & RHS

If the appearance of the finish bend is all important, particularly if no flattening or distortion of the product is desired, cold draw bending using an inner mandrel is recommended for CHS, SHS and RHS. This method can achieve bend centreline radii as low as 2 times the outside diameter (do) for CHS and 4 times the section dimension (d or b), in the plane of bending, for SHS and RHS.

Press Bending or Draw Bending Without a Mandrel CHS

If a little distortion can be tolerated the cost of bending CHS can be reduced by draw bending without the mandrel or press bending. Both these methods can achieve bend centreline radii of 4do to 5do for the lightest wall thickness pipe. Heavier wall CHS can be bent to tighter radii with minimum distortion.

Refer to the "DuraGal® Easy Welding Guide" for advice on welder setting and suitable consumables.

Tubeline®

As detailed in "Chemistry", Tubeline® & UltraPipe® CHS and Tubeline SHS/RHS are readily weldable in accordance with AS/NZS 1554.1 Welding of Steel Structures. The following are recommended consumables for welding Tubeline & UltraPipe CHS and Tubeline SHS/RHS:

Process Manual Metal-Arc (AS 1553.1) Submerged Arc (AS 1858.1) Flux-Cored Arc (AS 2203.1) Gas Metal-Arc (AS 2717.1) Recommended Consumables E41XX, E48XX (Grade 2) W402Y, W502Y W402X.X, W502X.X W502

Roll Curving

Roll Curving - CHS

Information received from specialist benders, using appropriate profiled rolls, has shown that bend radii from 100 mm on 26.9 OD to 1500 mm on 219.1 OD are possible. For more information contact the Roll Bending companies in your area.

Roll Curving - SHS & RHS

SHS and RHS can be economically bent by roll curving. Some distortion of the section will result using this method. If a flat roll, 3 roll bender is used, OneSteel Market Mills does not recommend bend centreline radii less than 30 times the depth of section in the plane of bending. If the 3 working rolls are profiled to suit the section being bent, bend centreline radii as low as 10 times the depth of section in the plane of bending can be achieved with reduction in section stiffness (Ix) of less than 10%.

PAINTING

DuraGal® / Galtube® Plus

The most cost effective way to use DuraGal and Galtube Plus products is unpainted, touching up any welds and black attachments. When painted or powder coated, the result provides enhanced surface protection. Authoritative research has shown that by teaming the inline hot dip galvanized coating with paint a synergistic effect occurs, ie. the corrosion life of duplex coating system can be 1.6 to 2.3 times greater than the sum of the corrosion lives of the zinc and the paint used separately. For weld touch-up, If DuraGal / Galtube Plus is to be used without topcoating, weld protection through the use of a zinc rich primer or epoxy mastic applied to a suitably prepared surface willl be sufficient for most applications. GALMET® "DuraGal Silver Paint" or any other equivalent colour matching paint may be used as a top coat for colour matching. If the DuraGal / Galtube Plus system is to be topcoated for exposure to more severe environmnetsthe weld areas should be adequately protected according to the coating manufacturers recommendations prior to topcoating. Some environments cause especially rapid corrosion. They include industrial areas, marine environments, polluted cities, some farming activities, animal husbandry and other corrosive environments. Refer to the "DuraGal Painting and Corrosion Protection Guide" available from OneSteel Market Mills for detailed recommendations on painting of DuraGal and Galtube products.

Channels bent on edge collapsed during the rolling process. It was thought that adding support rolls between channel flanges would stop this crushing failure and would allow successful roll bending. There was some minor scuffing/pick-up damage to the galvanized coating during roll bending, particularly on the edge of angles. The scuffing can be minimised if the rolls are smooth and hard. The galvanized coating should not flake off the steel substrate but some peeling due to mechanical pressure or rubbing can occur.

Other Products

Refer to your preferred paint supplier or painting contractor.

Crush Bending - SHS & RHS

Tight radius SHS and RHS bends can be formed by crush bending, often using the press bending technique. This method of bending dramatically reduces the sectional properties of the hollow section and is therefore only suitable for applications which are non loadbearing, or lightly loaded, unless the deformed section is stiffened.

PRODUCT INFORMATION

BENDING - Continued

Ram Bending - CHS

Testing has shown that good bends can be made in CHS up to DN50 using a well maintained, simple ram bender. It is critical that a suitable former be used. If the former being used fails to bend cold formed ERW pipe, it is usually because the former does not give good support to the pipe during bending and/or the bend centreline radius is too small. There is a range of suitable formers available from most Merchants, as set out below. An alternative range of formers is available from Dawn Tool & Vice. Because these formers are made from ductile iron, the surface finish of the completed bend is not as good as that achieved with the preferred formers. OneSteel has not tested Ram Bender Formers for CHS sizes larger than DN50 (60.3mm outside diameter) but this does not mean that the larger pipes can not be bent by this method. The difficulty of bending pipe increases as the outside diameter to thickness ratio (do /t) increases. OneSteel has successfully bent pipes with a do/t up to 27.4 (i.e. 60.3/2.2 = 27.4) If the bend is still collapsing when the support rollers are at the suggested centres then check the condition of your former. If the former is damaged and/or badly worn bend failures may occur. When bending CHS at these support pin centres it will generally be necessary to use a pivoting support block which is grooved to the OD of the tube being bent.

Recommended Weld Position

For best results, the weld should be touching the former in the shaded area, with the ideal weld location in the 3 or 9 O'Clock position. Problems encountered with ram bending. Flattening / Collapsing / Wrinkling Possible causes The former is worn or the former does not adequately support the pipe. Alternatives Try a former with an ellipitcal or cathedral profile to increase the side support, (recommended for Light and Extra-Light pipes). Go to a larger bending radius. Move the supports closer to the centre. Try a different bending technique. Try a heavier gauge pipe. Effect of Bending Former profile Using the Elliptical and Cathedral formers tabled in this section, a series of ram bending trials were performed on OneSteels' Tubeline® & DuraGal® Extra-Light (350 MPa) CHS, sizes DN 20,25,32,40 & 50. With conventional (circular profile) formers this range of pipe would typically be expected to require the use of an internal mandrel. The OneSteel results plotted on the chart below demonstrate how the increased side support to the pipe by the Elliptical and Cathedral profile, enabled the OneSteel pipes to be bent successfully without an internal mandrel.

Notes:

1. Centre line radius can vary between former manufacturers. 2. Results apply only to OneSteel products, and only for the sizes and grades listed above. 3. Roll type bender recommended for DuraGal DN50 Extra-Light

* Contact number for Dawn Tool & Vice: (03) 9462 1934 The Right Former

The most critical element is the former. It must give the pipe adequate support. Good results can be achieved from the simplest of benders if suitable formers are used. Three types of formers exist, each giving the bent section a different profile. Circular: Pipe generally falls to the bottom of the former. Absence of side support could result in pipe collapsing on bending. (Not recommended for Light or Extra-Light pipe)

Elliptical: Pipe sits close to, but not on, the bottom of the former. Good side support, sides of the former are above the centreline of the pipe.

Cathedral: Pipe sits on the entry to the former and will move to the bottom when bending starts. This action gives a small amount of squeeze that supports the lighter gauge pipe.

Ram Bending Hints

- Some wrinkling of the inside of the bend can be expected on CHS (DN32 and DN50 are most prone to wrinkling). - If the bend collapses (i.e. the centre of the bend lifts out of the former) during bending, move the support rollers in. For the support roller centres used during development and testing of the formers refer to the following table.

DEFINITIONS

Black

A smooth, even coat of clear polymer is applied to the external surface. This coating is meant to act as temporary rust preventative.

Mill (Cut) Ends

DuraGal® , Galtube® Plus and Tubeline® products have friction sawn or shear cut ends. There may be some rag. The cutting tooling is changed regularly to minimise the rag. Ultrapipe® is generally supplied with Bevelled ends.

Blue Painted

A smooth, even coat of blue general purpose paint is applied to act as a temporary rust prevention. See "Surface Finish" for RHS/SHS in this Product Information section for more details.

Nominal Size (DN)

A pressure pipe term, but commonly used by distributors to describe all circular hollow sections in sizes up to 165.1 OD. Historically it was used to describe pressure pipes with similar flow rates at a given pressure or head. Standards Australia has adopted DN (from French diametre nominel) as the nominal size designator for pressure pipe. NB, nominal bore (nominal inside diameter) was the term used in Australia up till the late 1980's.

CHS

Circular hollow section. Also called pipe or tube. These names originated from the designations "pressure pipe" and "mechanical tube".

Clear Coated

See "Black"

DFT

Dry Film Thickness of paint and polymer.

No Oil or Paint (NOP)

Both the external and internal surface of the hollow section is supplied in the "As Rolled" condition without protective coatings. Some dirt, usually loose mill scale, and mill lubricant contamination is unavoidable. The ends are not colour coded.

DualGrade® (DuraGal DualGrade)

DuraGal DualGrade is available in the standard thicknesses of DuraGal RHS & SHS. This range of DuraGal RHS & SHS complies with the requirements of AS1163 grades C350L0 and C450L0. (Refer to the tables and notes on pages 22, 23, 31 & 32).

Oiled

This is not a mill option for the OneSteel products within this publication.

Profiles

A high strength hollow section or angle, channel or flat that is in-line hot dip galvanized with a minimum average zinc coating mass of 100 g/m2 per coated side. Only the outside of the hollow sections is galvanized. See "Surface Finish" in this Product Information section for more details.

Quality

An indication of the wall thickness of CHS. Historically used to describe pressure pipe where each "Quality" designated pipes with similar pressure capacity. Changes in steel making and pipe manufacturing methods have overtaken this link. Five Qualities are commonly manufactured in Australia; Extra-Light, Light, Medium, Heavy and Extra-Heavy. Not all Qualities are available in all sizes. Generally the thickness of the pipe increases, as size increases, for a particular Quality.

DuraGal® Internally Painted

A DuraGal hollow section that has been internally painted over a prepared metal surface. See "Surface Finish" in Product Information at the front of this section for more details.

End Colour Coding

To assist in easy recognition of the thickness of SHS, RHS, angles, channels & flats and the Quality of CHS, a colour is applied to the cut ends of all Australian made sections, except Galtube Plus, UltraPipe and sections ordered with NOP (No Oil or Paint) surface finish. The end colour codes are set out in AS/NZS 4496: 1997 Recommended practice for the colour coding of steel products.

Red Painted

A smooth, even coat of red general purpose paint is applied to act as a temporary rust prevention. See "Surface Finish" for CHS in the Product Information at the front of this section for more details.

Galtube® Plus

A ductile hollow section that is in-line hot dip galvanized with a minimum average zinc coating mass of 125 g/m2 per coated side. This product is generally internally painted with an Zinc Phospahte paint over a prepared metal surface. This product has the same strength as AS 1163 C350L0 hollow section but with the ductility to allow the product to be further processed without splitting or tearing, ie. crush bending or flat trapping. See "Surface Finish" in this Product Information section for more details.

RHS

Rectangular Hollow Section. Often used to describe both RHS and SHS.

SHS

Square Hollow Section.

Tubeline®

Refer to the sectional property tables for details of sizes and shapes that can be manufactured within the different grade designations of AS1163.

HDG

See "Hot Dip Galvanized".

Hot Dip Galvanized

A process in which mechanically and/or chemically cleaned steel is submerged in molten zinc. This results in a zinc coating which forms a strong metallurgical bond with steel (without further processing) unlike electroplating, zinc spraying, painting with zinc rich coatings, mechanical plating or metallising. See "Surface Finish" in this Product Information section for more details.

UltraPipe®

For Structural applications, UltraPipe is tested to and complies with the requirements of AS 1163 Grade C350L0 and is included within the relevant tables for Large Structural CHS (168.3 to 457.0mm) hollow sections AS1163 Grade C350L0.

1. This table is calculated in accordance with AS/NZS 4600 using a design yield stress fy = 350MPa and design tensile strength fu = 380MPa. 2. Effective section properties are calculated in accordance with AS/NZS 4600. 3. All columns of the table (except for "Nominal Mass per m" and External Surface Area") are calculated using design thicknesses of 1.45mm and 2.4mm rather than the respective thicknesses t of 1.6mm and 2.5mm. This is to comply with clause 1.5.1.6 of AS/NZS 4600. 4. For Square and Rectangular Hollow Sections the outside corner radius r used in calculating the section properties is equal to 2 t for sections with thickness t £ 3.0mm and 2.5t for sections with t > 3.0mm.

This table is calculated in accordance with AS 4100 using design yield stress fy = 450 MPa and design tensile strength fu = 500 MPa as per AS 4100 table 2.1 for AS 1163 grade C450L0.

For SHS and RHS the outside corner radius r used in calculating the section properties is equal to 2t for sections with thickness t £ 3.0mm and 2.5t for sections with t > 3.0mm. DuraGal Dual Grade C350L0/C450L0 hollow sections have a minimum yield stress of 450MPa (fy = 450MPa), a minimum tensile strength of 500MPa (fu = 500MPa) and a minimum elongation equal to 16%, ie. the strength of AS 1163 grade C450L0 and the elongation of AS 1163 grade C350L0.
