TORICH 1010 1020 10# 20# Carbon Steel Hot rolled Seamless Steel Pipe Tube for Liquid Service GB/T 8163

GB/T 8163 10 20 Carbon Steel Seamless Steel Pipe Tube for Liquid Service

 Manufacturing methods 
1. Generally, the use temperature of boiler tubes is below 450 °C, and domestic tubes are mainly made of No. 

10 and No. 20 carbon steel hot-rolled tubes or cold-drawn tubes.

2. High-pressure boiler tubes are often used in high temperature and high pressure conditions, and the tubes 

will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe 

is required to have high lasting strength, high oxidation corrosion resistance, and good microstructure stability.
