What is the difference between HFW steel pipe and ERW steel pipe
The main difference between ERW (straight seam resistance welded) steel pipes and HFW (high frequency welded) steel pipes is their different principles. As the name suggests, resistance welding is a method in which pressure is applied through electrodes after the welding parts are assembled, and ...Read more -
Common methods for anti-corrosion of 3PE anti-corrosion steel pipe
Common methods for anti-corrosion of 3PE anti-corrosion steel pipes: 1. Steel pipeline anti-corrosion generally uses two main methods: outer coating and cathodic protection. 2. Although most of the surface of the pipeline is covered by the coating, a slight leak will cause incredible corrosion ra...Read more -

Performance processing of small diameter precision seamless steel pipe
1. The original state of steel, that is, the delivery state of steel pipes, can be divided into (codes in brackets): cold working/hard (BK), cold working/soft (BKW), stress relief annealing after cold working (BKS), tempering (GBK) ), normalizing (NBK). The commonly used state is the annealed sta...Read more -
Why does quenched steel need to be tempered
The main reasons for tempering quenched steel are as follows: 1. Eliminate internal stress: During the quenching process, large internal stress will be generated inside the steel parts. If not handled in time, internal stress will cause further deformation or even cracking of the workpiece. Tempe...Read more -
