SA335 Grade P22 Alloy Steel Chrome Pipe
Alloy Steel P22 Pipes
What is the yield strength of the ASTM A335 P22 pipe?
Before buying pipes it is essential to check its yield strength to use it without any failure but safely. As an experienced pipe consultant I can give the precise yield strength of the ASTM A 335 P22 pipe.
It happens when the internal pressure of the Pipe reaches the yield strength to deform and fail. The yield strength of pipes gets determined by many factors. It includes the strength of the SA335 P22 material, pipe size, pipe wall thickness, and others.
The yield strength of these pipes is around 205 MPa minimum. Hence it has high-pressure strength and elasticity for use in many industries like oil & gas, power plants, and chemical plants. P22 Alloy Steel welded Pipe made from chrome moly alloy, has excellent mechanical properties for high-pressure applications in power generation, heat exchangers, undersea operations, and others. Hence it is essential to know its yield strength and get certification to use them safely.
What is the chemical composition of the A335 P22 Pipe?
The low carbon A 335 P22 pipe has a chemical composition sulpur, manganese, molybdenum and chromium. Hence it has excellent properties for use in many industries.P22 Alloy Steel pipe has the following chemical composition.
How thick is the P22 Pipe?
While buying any pipe for many uses, it is essential to check its thickness to be suitable for fulfilling the purpose without any damage. P22 pipes have a wall thickness of 3mm to 12mm, so choose the right one.
It is easy to measure the thickness of these pipes if knowing the outer and inner diameters. The difference between the two is the pipes’ wall thickness. The pipe schedule will inform you about its wall thickness to choose the right one.

How do you measure SA335 Grade P22 Seamless Pipe diameters in mm?
There are two diameters you should measure before buying pipes. It is the OD or outer diameter and ID or inner diameter.
What temperature does the P22 Chrome pipe work at?
P22 Chrome pipe works well in steam boilers and other boiler parts because of its high-temperature resistance. The unique chemical composition of molybdenum in low-carbon steel makes it possible. Pipes made of A 335 P 22 material work well up to a temperature of 1094 F or 590 C. SA 335 Gr P22 ERW Pipes have a higher temperature range of 954 C to 1149 C or 1750 F to 2100 F.
What is the allowable stress of A335 P22 Material as per ASME B36.10M?
As per ASME or the American Society of Mechanical Engineers, the allowable stress is the maximum stress the pipes can withstand before code failure. Though it is not the entire pipe failure, it is for the many safety factors specified by ASME B36.01 M.
A 335 P22 material has an allowable strength as per B31.1 is the tensile strength at a specific temperature divided by 3. Since the tensile strength of the P22 material is 415 MPa and the temperature is around 500 C or 925 F, it is easy to calculate the allowable stress.
