ASTM A335 GR P22 seamless pipes are made from high alloyed material. These pipes are made from seamless ferritic alloys which have extreme durability and strength. These pipes are made of high quality material



ASTM A691 GR P22 alloy steel seamless pipes

Chemical composition:
These ASTM A691 GR P22 alloy steel seamless pipes and EFW pipes are made of silicon, molybdenum, nickel, tungsten, chromium, vanadium, manganese, vanadium and phosphorus. All of these pipes are highly alloyed and are highly used for heat applications. These pipes are suitable for all types of applications. These alloy steel seamless and EFW pipes are highly durable because of the combination.

The diameter of these pipes ranges from 17mm to 914mm. This GR P22 alloy steel seamless does not include a high amount of carbon. Low carbon compound makes the grade more ductile and durable. It also improves its carbide precipitation and abrasion.

ASTM A335 P22 Pipe specifies that it is made of carbon steel and contains just 1.9 per cent chromium. The material is as strong and corrosion resistant as austenitic stainless steel of the 304 grade, and it is less expensive. However, because of the hardness and toughness of the composition, the pipe has excellent wear and tear characteristics. Neminox Steel & Engineering Co. is a major producer of these ASTM A335 P22 Pipes, which are available in various sizes, shapes, and varieties. Contact us now for more information. The wall thickness of the pipes varies from 3mm to 12mm, depending on the diameter.

Pipes with greater diameters and lengths reaching up to 16000mm are available, with outside dimensions starting at 16.5mm and extending to a maximum of 16000mm. Carbon, manganese, phosphorus, sulfur, silicon, chromium, and molybdenum are all included in the P22 Pipe Material. The material composition's minimum tensile strength and minimum yield strength are 415MPa and 205MPa, respectively. In addition to fusion welding and GTAW, ER80S-B2 and other techniques, seamless pipe P22 may be joined together with various materials. Preheating and post-welding heat treatment are required for these techniques to ensure that the welded connection is secure.

The heat exchangers, condensers, power generating, petrochemical, and gas processing sectors are all examples of where the P22 Chrome Moly Pipe is used. The nominal bore diameters of the pipes vary from 12 inches to 3 inches in diameter. There are two forms of P22 Alloy Pipe: cold drawn and cold rolled, and they are employed in various applications under varied conditions. There are many different pipe forms, including square, rectangular, circular, and hydraulic pipe forms, and you can order any of them from us. To get a detailed pricing list for the SA335 P22 pipe and product specifications, please do not hesitate to contact us.
