Alloy Steel Pipe Classification Based on Intended Use

Alloy steel pipes are designed to meet specific industry requirements, leading to their classification based on application.

a) High-Temperature Alloy Steel Pipes

• Designed to withstand extreme temperatures and thermal stress.

• Examples: ASTM A335 (Chrome-Moly pipes).

• Applications: Power generation, boilers, and refineries.

b) Low-Temperature Alloy Steel Pipes

• Designed to perform well in cryogenic environments.

• Examples: ASTM A333 Grade 6.

• Applications: LNG (liquefied natural gas) plants and cryogenic storage.

c) Corrosion-Resistant Alloy Steel Pipes

• Designed to resist corrosion in harsh environments.

• Examples: Stainless steel pipes (316, 317L).

• Applications: Chemical processing, desalination plants, and marine environments.

d) High-Strength Alloy Steel Pipes

• Designed to handle high mechanical stress and pressure.

• Examples: API 5L X70, X80.

• Applications: Oil and gas pipelines, heavy machinery.
