ASTM A335 P91 Pipe

ASTM A335 P91 pipe is a type of high-strength, ferritic alloy steel pipe that is commonly used in power plants and other high-temperature applications. It is known for its excellent creep resistance and high-temperature strength.

ASTM A335 P91 Welded Pipe

ASTM A335 P91 welded pipe is a type of ASTM A335 P91 pipe that is manufactured by welding together two or more pieces of steel. Welded pipe is typically less expensive than seamless pipe, but it may not be as strong or durable.

ASTM A335 P91 Seamless Pipe

ASTM A335 P91 seamless pipe is a type of ASTM A335 P91 pipe that is manufactured without any welds. Seamless pipe is typically more expensive than welded pipe, but it is also stronger and more durable.

Material Testing:
The assured test to be done on each Alloy Steel P91 Pipes immediately after being fabricated are hardness test, flattening test, eddy current test, flaring test, micro, and macro test, Spectro analysis test, chemical analysis test, PMI test, and many more. These tests help to assure that all the Alloy Steel P91 Pipes are up to meet the quality standards of production thus they are being tested by a team of quality inspectors. The testing processes also ensure about the product’s workability and service life under several working conditions.

Marking of the product is done in accordance with the Alloy Steel P91 Pipes standards or as specified by the clients. Although marking and packing can be customized but the industry does standard marking including the batch code, trademark, lot no., grade, size and dimension at the ends of the pipes. There are many other documents that are being provided by the industry to claim the quality of the product to the client base.

Our entire Alloy Steel P91 Pipes range is widely appreciated by the client base in the market due to its easy installation, heavy duty performance, and low maintenance requirements.

FAQ

What is Alloy Steel P91?

Alloy Steel P91 is a high-strength, heat-resistant material commonly used in power generation, petrochemical, and other industries. It is made from a combination of chromium, molybdenum, and vanadium, providing excellent high-temperature strength, corrosion resistance, and weldability.

What are the common sizes available for Alloy Steel P91 Pipes and Tubes?

These pipes and tubes are available in a variety of sizes ranging from small diameters (e.g., 1/8" to 1" for tubes) to large diameter pipes. The sizes can be customized based on client requirements.

What is the thickness of a P91 pipe?

The outer diameter and wall thickness of P91 pipes vary, depending on the schedule, which can range from Sch 20 to XXS. The wall thickness of P91 chrome pipes typically ranges from 2mm to 14mm, with lengths reaching up to 16,000mm.

What is the difference between P22 and P91 material?

P22 contains 2.5% chromium and 1% molybdenum, while P91 contains 9% chromium and 1% molybdenum. P91 is a chrome-molybdenum alloy known for its exceptional strength and heat resistance. It is a creep-strength-enhanced ferritic (CSEF) material designed to improve creep strength.
