How to test seamless carbon steel pipe?

A regular inspection mechanism is established to regularly inspect the deformation, expansion, diameter, size and bending of seamless steel pipes.

Factors affecting the welding of ERW pipe

Common problems of high frequency welding and their causes and solutions: Welding is not strong, desoldering, cold stacking

Introduction of seamless pipe

Seamless tubes are made from solid round steel "bills" that are heated and pushed and pulled over a die until the steel is formed into a hollow tube.

How to order seamless carbon steel pipe?

In order to obtain steel pipes that meet the requirements of the buyer and the supplier to produce steel pipes that meet the requirements of the buyer, both parties must fully communicate and communicate in the "ordering" link.

How to conduct ultrasonic flaw detection for ERW steel pipe?

ERW pipe is made by using the skin effect and proximity effect of high-frequency current to rapidly heat the edge of the tube blank to the welding temperature, and then extrude and weld it.

What will affect the seamless stainless steel pipe?

Austenitic stainless steel welds contain more than 3% ferrite, which can effectively avoid solidification cracks, but too much ferrite will adversely affect performance.

what is valve?

A valve is a device used to control the direction, pressure, and flow of a fluid in a fluid system.

How to carry out quality control on seamless boiler tubes?

Boiler tubes refer to steel products that are open at both ends and have a hollow section.

How to improve the success rate of erw pipe in production?

From the analysis data of ERW steel pipe scrapping, it can be seen that the roll adjustment process plays a very important role in the production of welded pipes.

What is pipe beveling?

The groove refers to the groove of a certain geometric shape that is processed and assembled into the part of the weldment to be welded.
