ASTM A335 P22 Pipe

ASTM A335 P22 Pipe

P11 Pipe

ASTM A335 P22 pipe is a seamless ferritic alloy grade. SA 335 P22 seamless pipe is designed with a chemical composition of carbon, chromium, molybdenum, silicon, and other constituting alloys.

ASTM A335 P22 material has excellent corrosion and oxidation resistance properties across harsh environments. The pipes have high temperature strength and also work well in lower temperatures.

The P22 alloy steel pipe has high resistance to wear and tear in the systems. The pipes have enhanced elastic limit with good impact resistance. The ASTM A335 P22 restrains grain growth and is highly susceptible to embrittlement. The grade also has good creep strength and resistance to pitting.

The A335 P22 material is designed with a minimum tensile strength of 415mpa and a minimum yield strength of 205mpa. SA335 P22 material is thereby a good choice in pharmaceutical equipment, chemical systems, heat exchangers, condensers, power generation, and other applications.

The P22 pipe suppliers supply seamless pipes in standard sizes of 1/2 NB to 36 NB. These pipes are available in thickness range between SCH 40 to SCH 160 and XXS. The ASTM A335 Gr P22 pipes are designed in plain, bevelled, screwed, and threaded specifications.

Third Party Inspection of P22 Alloy Steel Pipe

ASTM A335 Gr P22 Hot Finished Seamless Pipe in Sch-40, Sch-80, STD, Sch-5, Sch-10, Sch-60, & XXS as per American standards ANSI/ASME B36.10M

Here the yield strength of the P22 material is 30,000 psi. Next, determine the safety base of the industry. E.g let us take 4 as the safety standard. Now divide the yield strength by the safety standard to find the allowable stress.

30,000 psi / 4 = 7,500 pounds per square inch.

The seamless ferritic alloy-steel pipe ASTM A335 Gr P22 is built to sturdily withstand high-temperature conditions. According to the ASME code, the recommended maximum service temperature for P22 material is 600°C or 1112°F. The exact operating temperature limits of the pipe are influenced by the application, pressure, duration of exposure, and corrosive elements.

The pressure rating and allowable stress for SA335 P22 pipe can be determined using established engineering codes and standards. These calculations take into account various factors such as material properties, and operating conditions of the P22 seamless pipe.

Gather information about the pipe’s outer diameter (OD), wall thickness (WT), and length to calculate the pressure rating of ASTM A335 P22. You also need to know the pipe’s mechanical properties, including the yield strength and tensile strength to calculate the values.

Refer to the applicable design code such as ASME B31.1 for power piping or ASME B31.3 for process piping. Employ the design formulas and equations from the selected code to calculate the pressure rating and allowable stress of the A335 Gr P22 pipe.

Tolerance refers to the permissible deviation in dimensions and mechanical properties allowed during the manufacturing process. Refer to the relevant product standard or specification, such as ASTM A335 to find the specific tolerance values for the P22 pipe.

Uses of SA335 Gr P22

Inclusions are non-metallic particles or impurities present in the pipe material and can influence its mechanical properties. After the SA 335 P22 pipe has been welded, defects such as lack of fusion, cracks, or porosity can show up in the weld zone. These defects can weaken the alloy pipe and reduce its integrity.

To detect these defects, manufacturers do a basic inspection method where the surface of the pipe is visually examined for any visible defects. Ultrasonic testing or UT is another method in which manufacturers use high-frequency sound waves to detect internal defects.

What temperature does creep cracking occur on a P22 welded pipe? What does creep crack growth occurs under?

Creep is a time-dependent deformation process that usually happens under sustained high temperature and stress conditions. Creep cracking in a welded A335 P22 pipe can occur at elevated temperatures where the material is subjected to long-term stress. Generally, creep cracking in an ASTM A335 P22 material pipe can occur at temperatures above approximately 500°C (932°F).

Creep crack growth refers to the progressive propagation of cracks under sustained high-temperature and stress conditions. To mitigate creep crack growth in a SA 335 Gr P22 pipe, employ proper welding techniques, post-weld heat treatment, and stress relief.

  • SA335 P22 material typically contains approximately 2.0-2.5% Cr and 0.87-1.13% Mo. While there is 1.0-1.5% Cr and 0.44-0.65% Mo content in P11 products.
  • The recommended maximum service temperature for P22 alloy steel is 600°C or 1112°F, while for P11, it is 550°C or 1022°F.
  • SA335 Gr P22 generally has higher tensile and yield strength compared to P11.
  • Due to its higher chromium content, P22 generally exhibits better corrosion resistance than P11.
  • P11 is more widely available and commonly used compared to P22.


How do you weld internally coated P22 Seamless Pipe?

Welding an internally coating ASTM A335 P22 pipe is not a simple procedure and requires precision tools to perform the task. Generally, MIG and TIG roots are used to weld the material to ensure a penetration weld.
The ASTM A335 Gr P22 grade pipe should ideally be welded first and later coated to protect the material.

How to calculate allowable stress of A335 P22 material?

The allowable stress of ASTM A335 P22 material is the maximum stress it can handle. To determine the allowable strength first find the yield strength of the material. Here the yield strength of the P22 material is 30,000 psi. Next, determine the safety base of the industry. E.g let us take 4 as the safety standard.

Now divide the yield strength by the safety standard to find the allowable stress.
30,000 psi / 4 = 7,500 pounds per square inch.

A study on Creep Crack Initiation and Growth Behavior of P22 Welded Pipe

The study of the creep crack initiation and growth behavior of A335 P22 pipe gave out the following results. The results indicate there is compact tension between the specimens. Here the P22 pipe is subjected to internal pressure and bending load. It also showed creep fracture on the mechanic’s parameter.
