Product Description



Cold drawn ASTM A53 A36 q345b 1.0425 p235gh 1.0345 20# 45# st45 seamless hydraulic honing carbon steel pipe hollow boil 


Boiler seamless steel tube adopts steel grade:

(1) High-quality carbon structural steel grades are 20G, 20MnG, and 25MnG.
(2) Alloy structural steel grades 15MoG, 20MoG, 12CrMoG, 15CrMoG, 12Cr2MoG, 12CrMoVG, 12Cr3MoVSiTiB, etc.
(3) The commonly used 1Cr18Ni9 and 1Cr18Ni11Nb boiler tubes with rust and heat-resistant steels should be subjected to hydrostatic tests, flaring and flattening tests one by one in addition to ensuring chemical composition and mechanical properties. Steel pipes are delivered in heat-treated condition.
In addition, there are certain requirements for the microstructure, grain size and decarburization layer of the finished steel pipe.
