Alloy Steel Pipe Fittings 3D 5D 10D Bend A420 WPL6, WPL3 ASME B16.9 Low Temperature Service

 

Kaysuns is passionately committed to provide a unique array of low temperature stainless steel elbows. These products are manufactured from the highest quality stainless steel and meet the market's prevailing specifications. In addition to this, each product we provide undergoes various tests to ensure that it meets the supplier's global quality standards.

 

ASTM A420 is the standard  for pipe fittings of wrought stainless steel and alloy steel for low temperature service. These fitting, either of seamless or welded construction, are primarily used in pressure piping and pressure vessel service at low temperatures. Kaysuns provides all the four steel grades covered by ASTM A420, WPL6, WPL3, etc

Material and Manufacture
The raw material for these fittings shall be fully killed steel, consisting of forgings, bars, plates, sheet, and seamless or fusion welded tubular products(pipes, tubes, or cylinders). The steels shall be made using recognized melting practices necessary to produce steels that shall meet the impact requirements of ASTM A420.


The ASTM A420 fittings may be made by forging or forming operations including hammering, pressing, piercing, extruding, upsetting, working, bending, fusion-welding, or machining, or by a combination of two or more of these operations. The forming procedure shall be so applied that it will not produce injurious defects in the fittings. All the fittings shall be furnished free of welding repair.

 

Heat Treatment
All fittings shall be furnished in the normalized, normalized and tempered, annealed, or quenched and tempered condition. All welding shall be completed prior to the austenitizing heat treatment. After forming, the fittings shall be allowed to cool below the lower critical before applying one of the heat treatments. When specified, post-weld heat treatment may be required.


Test certificates
Manufacturer test certificate as per EN 10204 3.1B, Third Party Inspection report( if the customer appointed before orders)
