TROUBLE AND MAINTENANCE FREE PERFORMANCE WHERE IT R E A L LY M AT T E R S Tungum Alloy (Aluminium-Nickel-Silicon brass) combines an unusually high strength to weight ratio, with ductility, excellent corrosion resistance, and first class fatigue properties. Highly resistant to sea water and its atmosphere, Tungum resists both stress and crevice corrosion to offer outstanding serviceability, even at intermittent duty in the highly corrosive `splash' zone. Also almost any industry recognised instrumentation tube fitting can be used in conjunction with Tungum Alloy - see page 19 for more information.

Non-magnetic and non-sparking properties make Tungum invaluable in piping high pressure gases, particularly oxygen where its thermal conductivity/ defusivity characteristics virtually eliminate the potential dangers present when lesser materials are employed. Tungum Alloy is a cryogenic material, suitable for chemical engineering and low temperature processes. Its corrosion resistance often enables its use in conveying fluids and gasses containing corrosive elements.

Tungum is uncommon among copper alloys, in that heat treatments include precipitation hardening. This enables its physical properties to be increased or decreased as required, to suit your circumstances. Tungum's high proof to ultimate stress ratio enables system proof tests to be conducted well above working pressure, without risk of permanent deformation taking place. When used in high pressure hydraulic or pneumatic circuits, these features together with inherent "clean bore" characteristics combine in affording an easily constructed, high integrity system. This requires a minimum of purging and no external protective treatment. Pages 6 & 7 illustrate just some of the many applications where a requirement for a tube exists, that has to be strong, capable of absorbing vibration, be resistant to corrosion and yet still bent into a complex shape. This has been more than satisfied by the use of Tungum Alloy.

Although initially more expensive than stainless steel, the proven life expectancy of TUNGUM make the long-term operating costs far more attractive. For example, the price of instrumentation tubing for a standard rig using stainless steel compared with using TUNGUM alloy is approximately half. However, by using stainless steel you can expect 5-10 refits over the life of a rig and, just by taking the price of tubing into account, costs quickly escalate as demonstrated in the graph. Not to mention the costs involved in rig shut down and `old' tube disposal. Another cost benefit is that, as a copper-based alloy, TUNGUM is relatively easy to bend, resulting in vastly reduced installation times compared to stainless steel up to 1/3 less is not uncommon. Bearing in mind that the average installation costs for stainless steel are in the region of £17 - £30,000, further savings will be significant.

BP and Shell have standardised Tungum tubing for hydraulic and pneumatic lines on refits and new gas platforms.

In salt-laden marine atmospheres, `316' stainless steel is highly susceptible to crevice corrosion and chloride pitting. After just a few years of salt spray exposure, it may still look bright from a distance, but closer inspection reveals telltale signs of imminent failure to hold pressure. TUNGUM alloy, however, possesses a natural protection mechanism whereby, on exposure to salt spray, a very thin oxide coating is generated over the exposed surface, no more than two thousandths of an inch thick, when complete. The tube becomes discoloured, it may even have a verdigris coating, but under the oxide layer the tube material is perfect and will remain so for a very long time. TUNGUM has been in use offshore since 1978 and industry awareness of its superiority for use in marine environments is increasingly evident as more and more operators question the use of stainless steel from both safety and economic viewpoints.

You don't need to be a mathematician to work out the economic advantages of TUNGUM alloy which is not only capable of lasting the life of the platform but will also give trouble and maintenance-free performance throughout.

M A R I N E C O R R O S I O N R E S I S TA N C E OF TUNGUM ALLOY

Of the environmental conditions in which engineering products daily have to operate, none poses a greater or wider problem than sea water and the associated saline atmosphere, which frequently exists for many miles inland. The life expectancy of equipment is often drastically reduced and in areas where corrosion has already taken place, predicting failure as a basis for preventative maintenance is difficult if not impossible. At its most aggressive, in the presence of oxygen, sea water attacks most `standard' materials in a variety of differing but equally costly ways: -

TU NG UM ALLOY

TUNGUM ALLOY has been developed to counter the problems of sea water and in practice has already done so for over 40 years. Whether total immersed, or in the highly active `splash' zone Tungum Alloy affords exceptional resistance to the effects of marine environment. Unaffected by either stress or crevice corrosion, Tungum Alloy is protected by a speedily self generated oxide coating which, once formed, prevents further attack. If this oxide coating is damaged it does of course quickly repair itself.

Tungum alloy tube remains unscathed despite more than 10 years marine exposure on a semisubmersible support vessel. The stainless steel section, from a southern North Sea gas platform, shows both crevice corrosion and chloride pitting after barely five years in the same environment, inlines under pipe clamps.

The special corrosion resisting characteristics of Tungum Alloy tubing, carefully developed for use in the hydraulics systems of marine aircraft remains just as valid in todays polluted sea waters. The development of the oxide coating is illustrated by the graph below. This shows time plotted against a minute weight loss during its formation. After 1000 hours the weight has virtually stabilised indicating that the protective coating is already almost complete. A fact confirmed in the laboratory by the most rigorous tests and backed by experience of countless practical and demanding applications. Many of these more than 50 years standing.

GALVANIC SERIES OF EN GIN EERING MATERI ALS

The table opposite shows the relative position of Tungum Alloy to other well known materials when placed in galvanic series. In general significant galvanic corrosion does not take place when copper is coupled to its alloys or when different copper alloys are in contact with each other. The amount of galvanic corrosions on a less noble metal will depend on the relative areas of the two metals in contact and the potential or voltage existing between them in a given environment. For example a large mass of copper, or its alloy should not be coupled to a small mass of reactive material such as iron, zinc or aluminium. On the other hand the coupling of a copper, or its alloy having a small area relative to the area of the more reactive metal will often prove to be satisfactory. Generally a good electrical contact in a metal to metal joint will be greatly reduce the possibility of galvanic corrosion.

The strength to weight ratio of Tungum Alloy compares most favourably with other materials. In tubes, this often affords the opportunity to employ SMALLER, LIGHTER SECTIONS ­ reducing the size and cost of fittings and supports also easing handling during fabrication, opening the way for more compact space systems. The graph shows the results of burst tests conducted on identical samples of 1/2" O/D x 20SWG tubing. Room temperature design strengths taken from BS1306 clearly confirm the outstanding performance of Tungum Alloy relative to other copper based materials.

FAT I G U E & L O W T E M P E R AT U R E CHARACTERISTICS

As would be expected of a material originally developed for use in the hydraulic control systems of aircraft, Tungum Alloy has excellent fatigue resisting properties. Today, pulsing pressures and vibration are recognised as being a major factor influencing the integrity and performance of all hydraulic systems irrespective of the application. In practice, tubing is often used after bending. In this operation the outer wall of the tube becomes thinner and the inner wall thicker. The severity of this depends on the radius of curvature and the angle encompassed by the bend. The tube also becomes oval due to the forming operation. The radius of the bend, the angle of the bend, the ovality of the tube and obviously properties of the tubing material, all influence its fatigue life. The relationship between the maximum stress, calculated for straight and circular Tungum Alloy tubing, and the number of stress repetitions to cause failure is shown below. The graphs are based on the results of tests carried out in controlled conditions and are reproduced for guidance purposes only. Tungum Alloy satisfies many low temperature and cryogenic applications. The mechanical properties of the Alloy all improve with reducing temperatures down to as low as - 196°c. The impact resistance also remains substantially unchanged over the same temperature range. The table opposite compares the properties of solid, hard as drawn Tungum alloy at 15°c and -196°c.

DESIGNING WITH TUNGUM ALLOY

Realising the full potential of a high strength corrosion resisting material such as Tungum Alloy, requires careful consideration from first principles. All too often, time is at a premium and temptation exists to cost competing materials on the basis of identical sections (ignoring opportunities afforded by the higher strength of the superior material). Whilst the temptation is a real one, the resultant system will often be more costly than is necessary or, indeed on occasions, the costing may indicate that the budget will simply not allow a maintenance free material to be fitted. The former is undesirable, the latter is often regretted for life even when time is at a premium, the best system will always result from following the procedures outlined below: Remember the corrosion resistance, cold working and clean bore characteristics of Tungum Alloy combine to give the advantage of: · Eliminating the need to protect the tubing from the elements prior to and during fabrication. · Reducing the time and, most importantly, the cost involved in purging a system of contamination · Minimising the risk of damage to expensive circuit control equipment · Virtually eliminating maintenance costs

MAXIM UM WORK I NG PRESSU RE

In the tables (pages 14-17 inclusive), the values for maximum working pressures are calculated on a 4:1 safety factor. Theoretical burst pressures (4 x maximum working pressure) are calculated in accordance with the formula quoted in BS1306; using a minimum ultimate strength of 430N/mm2 (27.84 Tons/sq in). The figures shown are for tubes in the straight, "as supplied" condition.

Establish the operating parameters: · Working pressure · Flow rate required · Operating environment · Reliability required · Maintenance difficulty rating · Other special consideration (such as the consequences of failure in a vital system)

Select the required tube section. Taking into account that high strength materials ( such as Tungum Alloy ) afford an opportunity of using thinner walled tubes. Frequently, even smaller tubes have the same capacity as larger ones in lesser material. The benefits to be gained are often substantial in contributing to: · The cost effective use of tubing · Ease of manipulation / fabrication · Simplified handling during construction · Reduced cost as a result of using smaller tube fittings and clamps · Smaller, more compact systems, through the use of smaller sections

12

MAXIMUM WORKING PRESSURE

Engineering installations demand that a safety factor be applied when establishing the sections of material to be used. The maximum working pressure will be the minimum theoretical burst pressure of the particular section divided by the desired factor of safety. BS.1306 recommends a factor of safety of 4:1 for copper alloy tubes used in pressure vessels. If when installing Tungum tube it has to be heated to a temperature in excess of 700°c, its original properties may be restored by a precipitation hardening treatment carried out at 500°c for 1 hour and air cooled.

NOTE: Some of the standards only apply to certain tube sizes or special mill orders. Please check with us before ordering. · BS EN 12449 CW 700R, Cond. R430 (Formally BS 2871 Cond. O) ­ Identified as alloy CZ.127 · British Standard 1306- WP Cond. · American Standard A.S.T.M B706-TF - Identified as copper alloy UNS C.69100 · French National Standard UZ.15.NS · Ministry of Defence Specifications: Def.

Tungum Alloy is Eddy current tested as standard in accordance with the requirements of BS. 3889 and ASTM E.243-85. (In lieu of or equivalent to a 1,000 psi pressure test). Further hydraulic pressure testing can be carried out at the customer's request. These are normally specified at 310 bar (4,500 psi) or 465 bar (6750 psi).

Note: · These are pre-delivery test pressure levels. They do not determine the working pressure capability of any given tube size. · Pre-delivery hydraulic tests to customer specific levels can be carried out on request.

Tungum Alloy tubing and fittings also have the approval of: · Lloyds Register of Shipping · Det Norske Veritas

Tungum Ltd is totally dedicated to the concept of quality. The Quality Management System is approved to: · BS EN ISO 9001-2008

FA B R I C AT I N G S Y S T E M S IN TUNGUM ALLOY

Tungum Alloy's special combination of high strength and ductility make it a very easy material to use on even the most complex of systems. The ease with which it can be cold bent and manipulated, means that there are often significant reductions in the system installation time compared to other materials, particularly stainless steel, copper nickel and monel. Almost any industry recognised instrumentation tube fitting can be used in conjunction with Tungum Alloy tubing. Twin or single ferrule 316 stainless steel compression fittings tend to be the industry standard and are commonly used without the need for modification to the standard bite ring or tightening method. Also 37° flared, brazed or silver soldered fittings are widely used and work very well. Please note that common brass compression fittings that use a brass bite ring are not normally recommend. This is because the brass bite ring is generally not hard enough to create the "bite" in to the surface of the tube. For a permanent hard piped system Tungum can offer a fitting system that features a silver solder flat face nipple design that is widely specified in the industry. We can supply these fittings in all sizes and configurations to use with our material.

N OTES ON DESIG N ING AN D INSTALLI NG PI PEWORK

· Select the appropriate wall section for the pressure and service. · Design pipe runs to allow access and easy removal of important equipment. · Provide adequate and correctly placed supports; to ensure vibration is controlled to an acceptable level. · Select clamps which are `kind' to the tube surface, but which grip it tightly. · Employ bends generously using the same radius throughout. Always allow adequate room for clamping between bends. · Ensure each pipe fits correctly without imposing additional loads on couplings/pipe joints. · Protect small diameter pipe runs against being used as ladders or hand hold.
