Since decades, these alloys have successfully used in:? Merchant and military shipbuilding? Offshore oil and gas installations?
Coastal petroleum and petrochemical processing plants? Seawater desalination plants? Coastal electricity generation plants Copper-nickel alloys are widely applied in:? Seawater cooling systems? Fire water systems? Sanitary systems? Deck steam pipes? Deluge systems? Hydraulic and pneumatic systems? Seawater feed lines to desalination and processing units? Controlled content of alloying elements and minimised concentration of impurities ensure reliable service and fabrication properties of the alloy.
Main Advantages of Osna? Simple alloying system with good weldability? Excellent ductility and toughness? Outstanding erosion corrosion performance? Resistant to uniform and localised corrosion?
No effect of ambient seawater temperatures? No effect of seawater chlorination? Resistant to biofouling? Resistant to stress-corrosion cracking? Low maintenance costs? DIN WL 2. BS CN DIN EN 9. Although the pipe dimensions of 38 and 40 inch are not included in the EEMUA — they are available here as they are commonly specified in offshore projects. Based on ASME specifications, additional components are included. The fit-for-purpose corrosion allowance of 0.
Mechanical properties of pipes are given in Appendix A. Flanges Composite and Solid:? The copper-nickel stub end and flange joint faces are machine finished and comply with the corresponding Sections of EEMUA and are summarized in the Appendix A. The specification comprises a series for pipe fittings including butt weld, socket welding, capillary brazing, threaded, self reinforced fittings as well as saddle pieces. Welding The welding consumables used for the manufacturing of welded components are in accordance with AWS-A5.
Gaskets The gaskets normally used with flanges are those made from aramid fibre with nitrile binder in accordance with ASME B The gasket hardness shall not be less than 75 Shore. The gaskets shall not be graphited. In order to ensure adequate seating when solid weldneck and solid slip-on flanges are used, irrespective of gasket materials, the gaskets shall be located within the bolt circle.
Note: Gaskets should not be used when mating with elastomerlrubber faced flanges. Please contact us for more information. For decades now, KME has been consistently putting into action the corporate idea of quality, and, with it, gained the reputation of being a reliable supplier throughout the world.
The fulfilment of our customers expectations as to KME products and services in all re? KME Quality Management System comprehends process-integrated quality controls, internal product and system audits, the systematical training of all employees and the operating of computer aided statistical methods.
The results of KME production give convincing proof: our results have been surpassing the requirements of national and international standards for years.
KME produces quality. They are manufactured from hot extruded shells followed by cold work and annealing. Mechanical testing is carried out in accordance with the standards above.

EEMUA 145 Weld Neck Flanges
Connections with pipe couplings 4. You can check copper nickel butt weld pipe fittings on our website , there are five main butt weld copper nickel pipe fittings. Elbow, reducer,tee,saddles and end cap. Pros: Strength and stability of the welded join is similar to that of the joined parts material Conservation of space Cheaper fabrication using no extra fittings Cons: A solid join, cannot be disconnected Assembly time is longer When different materials need to be joined, the welding process becomes more complex Sometimes the galvanic insulation is poor Welding must be performed in a clean and fire-hazard free environment 4.
