ASTM A335 Grade P22 Alloy Steel Seamless Pipes Supplier

Q: What is ASTM A335 P22 material?

ASTM A335 P22 is a seamless carbon steel alloy pipe that is enhanced with the addition of elements like chromium and molybdenum. Chromium is particularly important because it significantly improves the pipe's resistance to oxidation and boosts its strength, yield, and hardness at elevated temperatures, making it ideal for high-pressure service.

Q: What is the equivalent of ASTM A335 GR P22?

The ASTM A335 P22 grade has several recognized equivalent material specifications across different standards. These equivalents include the ASME designation SA335 P22, the corresponding tube grade T22, and international standards such as 10CrMo910, 10CrMo9-10, 1.7380, and 1.7383.

Q: What is the hardness of A335 P22 pipe?

While specific hardness values can vary, these pipes are required to meet certain mechanical standards. For instance, a similar high-alloy grade, P91, must not exceed a hardness of 250 Brinell (HB). Additionally, depending on size and wall thickness, the pipe may be subjected to a bend test instead of a flattening test to confirm its material integrity.

Q: What is the temperature limit for ASTM A335 P22?

ASTM A335 P22 Pipes are specifically engineered for continuous high-temperature service. They are generally considered suitable for continuous operation at pipe wall temperatures up to approximately 590°C to 600°C (1094°F to 1112°F). Proper heat treatments, such as normalizing and tempering, are essential to ensure the pipe maintains its strength and resistance within this demanding temperature range.

ASME SA335 P22 Alloy Steel Seamless Pipe Manufacturer and Supplier in USA

ASTM A335 P22 Alloy Steel Seamless Pipe or ASME SA335 P22 Pipe is high-performance alloy steel pipeline manufactured out of chromium-molybdenum (chrome-moly) grade alloy, and therefore has better performance properties when it is exposed to high pressure and high temperatures. It is a ferritic alloy steel pipe that is formed according to the ASTM A335 standards and is high strength, creep resistant and thermal stable therefore it is the most appropriate to be implemented in industries that need high performance in their work.

ASTM A335 P22 Chromium-molybdenum alloy steel pipe

The ASTM A335 Gr P22 pipe is made of a balanced chemical composition of 1.902.60 percent chromium and 0.871.13 percent molybdenum, which gives the pipe excellent resistance to oxidation, corrosion, and thermal fatigue even in the longer term when subjected to extreme environmental conditions. It provides a minimal yield strength of 205 Mpa, tensile strength of 415 Mpa, making it very reliable and long term and at the same time provides good weldability and formability.

The pipes we offer in USA Piping Solution are of high quality in terms of ASTM A335 P22 seamless pipes that follow the international standards in boilers, heat exchangers, superheater tubes, and steam pipelines that operate at temperatures of more than 540 degree celsius. The chrome moly steel pipes are popular in the power generation and oil refining and petrochemical industries where durability and precision engineering is mandatory. All the pipes are inspected, and non-destructive testing is practiced so that every pipe is of consistent quality and performance.

Frequently Asked Questions About ASTM A335 P22 Seamless Pipes

What is ASTM A335 P22 material?

ASTM A335 P22 refers to a smooth pipe made of carbon steel alloy material that is uninterrupted with the incorporation of other elements such as chromium and molybdenum. Chromium is quite significant in the sense that it greatly enhances the resistance of the pipe to oxidation and increases its strength, yield and hardness at high temperatures which make it suitable in high pressure service.

What is the equivalent of ASTM A335 GR P22?

There are multiple material specifications of ASTM A335 P22 grade that have been used under other standards. These equivalents are ASME designation SA335 P22, the equivalent tube grade T22 and international standards 10CrMo910 and 10CrMo9-10 and 1.7380 and 1.7383.

What is the hardness of A335 P22 pipe?

Although the values of specific hardness may fluctuate, these pipes must comply with some mechanical standards. An example of a similar high-alloy grade, P91, should not be allowed to exceed a hardness level of 250 Brinell (HB). Moreover, the pipe can be tested on a bend test rather than flatten test, depending on its size and the thickness of its walls, to ensure integrity of the material used.

What is the temperature limit for ASTM A335 P22?

ASTM A335 P22 Pipes are designed to be used continuously at a high temperature. They tend to be thought to be capable of steadfast functioning at wall temperatures of the pipe up to about 590 o C to 600 o C (1094 o F to 1112 o F). Normalizing and tempering are the right course of action to make the pipe strong and resistant enough to remain in this challenging temperature range.
