• We are a specialized manufacturer, stockist and supplier of A335 P22 alloy steel pipes in Morocco. P22 alloy steel pipes contain min. 1.9% chromium and 0.87% molybdenum, and offer minimum tensile strength of 415 MPa and yield strength of 205 MPa. The available data suggests that P22 grade alloy pipes have excellent fabrication properties and adequate long term strength, making it a suitable choice for use in high temperature erosive power generation applications.

• A335 P22 alloy steel pipes are mainly used in power generation industry for manufacturing boilers, pipeline and heat exchangers, and are generally suitable for bending, flanging, and similar forming operations, and for fusion welding. 

• With a collective experience of over 30 years, we have emerged as one of the largest just in time exporter of P22 alloy steel pipes to Morocco. ASTM A335 P22 alloy steel pipes are used in conjunction with ASTM A234 WP22 buttweld fittings, A234 WP22 elbow, A234 WP22 Tee, A234 WP22 reducer, A234 WP22 180 Degree U bends, and A182 F22 forged fittings and flanges. All these materials have similar chemical (Chrome, Moly, Nickel) and mechanical properties and can be easily welded and installed on site.

• We are devoted to provide the best solutions for our customers in Agadir, Kenitra, Oujda, Rabat, Meknes, Salé, Marrakesh, Tangier, Fez, Casablanca, the biggest industrial and commercial cities of Morocco. We have manufacturing set up, sales and export offices in both India and China to meet the immediate and long term alloy steel pipe requirements across Morocco. We aim at offering high quality but competitive price chrome moly P22 pipes for our global customers.

Equivalent Grades & Applications for P22 Alloy Steel Pipes

• The equipment and pipelines in the power generation industry are manufactured from chrome-molybdenum P22 alloy steel pipes, also known as A335 P22 Gr. pipes. We are a specialist supplier of P22 or T22 steel tubes for boilers and heat exchangers to various power generation units in Middle East, Africa and Eastern Europe.
• P22 alloy steel pipe shall not have a hardness not exceeding 250 HB/265 HV [25HRC].
• ASTM A335 P22 Pipe (ASME S/A335, Chorme-Moly) is a seamless ferritic Alloy-Steel Pipe for high temperature service.

ASTM A335 is a standard specification for seamless ferritic alloy-steel pipe for high-temperature service. The specification generally covers “chrome-moly” seamless pipes with remarkable resistance to corrosion and good tensile strength at high-temperature service. The testing requirements for these pipes include the following:

• Transverse/longitudinal: tension and flattening, hardness, bend tests- for material which has been heat-treated in batch furnaces, these tests shall be made on the 5% of the pipes from each heat lot number. For smaller lots, one pipe at a minimum has to be tested
• ASTM A335 Gr. P91 shall have a hardness of 250 HB / 265 HV (25 HRC)
• Hydro testing: shall be applied to every length of pipe
• The non-destructive electric test is optional
