Description

High Pressure Boiler Tube Alloy Steel ASTM A335 P92 56'' 1422mm x 140mm

In order to improve the heat efficiency of reheating steam pipeline in power plant, the reheating-temperature can be designed as high as 621°C, which is known as the super-critical temperature. The Unite States firstly developed ASTM A335 P92 alloy steel in late 1980’s to meet the heat-resisting requirements of such a high-temperature power unit. The alloy steel P92 is an improved version of ASTM A335 P91 alloy which has deliberate addition of tungsten, vanadium, niobium, decreased amount of molybdenum to fine-tune to ferrite/austenite ratio, as well as carefully controlled amount of boron and nitrogen.

1. Standards

ASTM A335 ——Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service

2. Application

For the high-pressure boiler and steam pipes, and the petrochemical industry pipes;
Power plant; Chemical Fertilizer; Petrochemicals; Offshore Oils; Gas Productions; Refineries and etc.
