ASTM A335 P5, P9, P11, and P22 – Common Use Grade
Chrome Moly Alloy Pipes like ASTM A335 P5, P9, P11, and P22 are widely used in high-temperature environments, particularly in the power and petrochemical industries.
These pipes are seamless and made from chrome-moly alloy, designed for use at high temperatures. They usually contain chrome (1.00% to 1.50%) and molybdenum (0.44% to 0.65%), giving them high toughness and resistance to wear.
The ASTM A335 specification ensures these pipes have a minimum yield strength of 205 MPa and a minimum tensile strength of 415 MPa. They are suitable for making various pipe fittings like elbows, tees, reducers, and flanges, meeting standard requirements for seamless alloy pipes with specific wall thicknesses. These pipes can also be bent, flanged, and are suitable for fusion welding.
In UK, McNeil Instrument supplies these high-quality pipes, ensuring reliable performance in demanding applications.
