3PE anti-corrosion steel pipe is a high-level anti-corrosion steel pipe. It is composed of primer + glue + PE three-layer anti-corrosion. It has high corrosion resistance and high wear resistance. Well, once the anti-corrosion layer is destroyed, it will corrode quickly, and the parent body of the 3

When purchasing stainless steel pipes, we are often overwhelmed by the surface conditions of stainless steel pipes. Is the original surface better or the dull surface better? Let's take a look at the processing methods of these two surfaces, which may inspire you a little differently.Original surfac

Welding, also known as fusion, is a manufacturing process and technology that connects metals or other thermoplastic composite materials (such as plastics) through heating, high temperature, or high pressure. There are three welding methods:1. Fusion welding. The workpiece is heated to form a molten

In order to improve the corrosion resistance of thick-walled steel pipes and prolong the service life of the products, the thick-walled steel pipes need to be pickled and passivated to form a protective film on the surface. Thick-walled steel pipes have high hardenability, good machinability, modera
