Boiler steel pipe

Boiler pipe introduction

1、Boiler Pipe Size，Boiler pipe size range complied with the different ASTM standard required. Like ASTM A106 or ASTM 179, 192 etc.

But most of the boiler pipe size is small, outer diameter usually less than 1 1/2” (1/4”, 1/2”, 3/4”, 1” and 1 1/2”). Then 2”, 2 1/2”, 3” and maximum to 4”.

2、Medium and high pressure boiler pipe differences，Based on different working temperature, the medium or high pressure boiler pipe shall be used. Normally classified as below cases:

a. The operation temperature of general boiler pipe is lower than 450℃. The medium pressure boiler pipeline mainly adopts hot rolling process or cold drawing process.
b. High pressure boiler pipes are often used in high temperature and high pressure conditions. Under the action of high temperature flue gas and steam, the pipe will occur oxidation and corrosion. It is required high pressure boiler pipe that has high durable strength, high oxidation corrosion resistance and good tissue stability.
