Welding of low alloy heat resistant steel

The strength properties of carbon steels decline sharply with the increase in working temperature, and their ultimate working temperature is about 350°C. If they are used at higher temperatures, certa

How straight seam steel pipe is measured in length

According to the production process of LSAW steel pipe, we can be divided into two kinds of high-frequency LSAW steel pipe and submerged arc welding LSAW steel pipe, and we would like to know the form

Precautions for purchasing LSAW steel pipe

LSAW steel pipe is a kind of steel pipe which is parallel to the longitudinal direction of the steel pipe, it has the advantages of wide application field, simple production process, high production e

Straight seam steel pipe into the process of pipe bending

LSAW steel pipe is mainly used in waterworks, petrochemical, chemical, electric power industry, agricultural irrigation, urban construction; for liquid conveying: water supply, drainage, for gas conve

How to prevent straight seam steel pipe from breaking?

Straight seam steel pipe is a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. Generally divided into metric electric welded steel pipes, thin-walled electric we

Quality inspection method for straight seam steel pipes

Straight seam welded pipes, steel pipes made by coil welding of hot-rolled or cold-rolled steel plates or steel strips, and pipes obtained by straight seam welding on welding equipment are called stra

Difference between ERW and SAW

Submerged arc welding (including submerged arc surfacing and electroslag surfacing, etc.) is a method of welding by burning the arc under the flux layer. Resistance welding is a welding process that m

Advantages of argon arc welding priming

Argon arc welding is a welding technology developed from the principle of ordinary electric arc welding, through the high current will be welded material in the welded base material melted into a liqu

What is gas welding? What is the difference from normal welding?

Welded steel pipe using the billet is a steel plate or strip steel, because of its welding process is divided into furnace welding pipe, electric welding (resistance welding) pipe and automatic arc we
