ASTM A335 P91 Pipes

The ASTM A335 P91 Pipes are a representative of state-of-the-art engineering. As a pipe, it finds its application in places where the temperature and pressure are high. They are, therefore, fabricated to meet the strict guidelines laid down by ASME, ASTM, and API. These pipes find the most demand for oil and gas, petrochemical, and power industries. A M Industries are proud to be one of the largest manufacturers of ASTM A335 P91 Pipes whose products epitomize durability, reliability, and excellent performance.

This exceptional performance of the ASTM A335 P91 Pipe is mainly because of its chemical composition. The main constituents in it are 0.40% nickel, 8% to 9.5% chromium, and 0.85% to 1.05% molybdenum, along with traces of other elements in it. This is the reason the ASTM A335 Grade P91 Steel Pipe has great strength and excellent corrosion resistance, which makes it indispensable in high-temperature applications.

Also, during the processing stage of this pipes, the procedures in use normalize them at about 1050 °C; this results in a great improvement in their creep resistance. The ASTM A335 P91 Pipes Suppliers provide a product whose minimum tensile strength is about 585 MPa and whose minimum yield strength is 415 Ksi. More importantly, these pipes can elongate by at least a minimum of 20%, thus acquiring the integrity to hold up under stress. Generally, unlike other grades, ASTM A335 P91 pipes have a maximum hardness of 250 HB and therefore are easier to weld and process.

The Seamless P91 pipe is one of the special types of the ASTM A335 P91 intended for applications where structural integrity is required without the use of welds. These pipes, due to no weld and no stress concentration, have better performance compared to their welded version, especially in large sizes of diameters. The size ranges from 1/8 NB to 24 NB, the outer diameter ranging from 19.05 mm to 114.3 mm, and it is available in custom-made rectangular, square, and also round shapes.

The Stockists of the ASTM A335 P91 Pipes ensure it in a wide range for different industrial applications. This SA 335 Gr P91 High-Temperature Seamless Pipe is suitable for applications in industries and refineries at temperatures as high as 600-degree Centigrade with its extremes of temperature capacity. Coatings of epoxy, FPE, galvanized, or annealed finish protect these pipes from corrosion, increasing service life and reducing maintenance burdens. We export an assorted range in the stock of the ASTM A335 P91 Pipes Exporters to custom lengths down up to 16,000 mm in length.
