Silver Tubes are the best manufacturer, supplier, exporter and stockiest of the commendable quality of ASTM A 335/ A691 GR P2 Alloy Steel Seamless & EFW Pipes. We are providing the comprehensive ranges of same to allow clients to satisfy all application desires. It can be collected from us at specifications that vary in specifications, wall thickness, types, forms, lengths, ends, etc. To enhance the mechanical properties of Alloy Steel Seamless Pipes, steel is alloyed with the ranges of alloys in the total quantity of 1.0% to 50% by weight for producing the alloy steel. Alloy steel addition to the carbon is containing substantial amounts of other alloys such as silicon, molybdenum, nickel, tungsten, chromium, vanadium, manganese, vanadium and phosphorus. These alloyants addition is complementing steel with well-increased strength, hardness, and resistance to chemicals. A691 specification is covering steel pipes of 16” in the outer diameter or larger that is EFW or electric fusion welded with the addition of filler metal, fabricated from the pressure vessel quality plate and it is ideal for the greater pressure services at moderate temperatures. Several grades designate the type of plates used. Classes designate the heat treatment to be performed at the time of production of the pipes, the pipes are pressure tested or weld is radio-graphically examined. ASTM A 335/ A691 Alloy Steel Seamless & EFW Pipes are tested using PMI-IGC test, hardness test, Flattening-flaring test, mechanical-chemical test, macro-micro test for quality assurance. The Pipes are packed using wooden cases, wrapped in plastic sheets for safer delivering.
