ASTM A519 Carbon steel mechanical pipe is a cold processing mechanical pipe produced according to ASTM A519 standard, mainly used in mechanical equipment, automobiles, industrial components and other fields.

Schedule 40 Carbon steel pipe is a pipeline product according to American standards, widely used in water, gas, oil and natural gas and other low pressure transmission systems.

Oil casing seamless carbon steel pipe is made of low carbon steel through perforation, drawing or hot rolled seamless process, used in oil well casing.

The ASTM A36 steel plate is a low-carbon structural steel plate produced in accordance with the American Society for Materials and Testing (ASTM) A36 standard.

3PE/3PP, also known as three-layer structure polyethylene/propylene protection, is an advanced external corrosion prevention technology, the use of these two coatings can effectively reduce the corrosion of carbon steel pipes, enhance the service life of carbon steel pipes.

The epoxy coating on the inside of the steel pipe can effectively isolate the contact between the corrosive medium and the inside of the steel pipe, and reduce the corrosion inside the steel pipe.

Small-orifice seamless pipe is a kind of pipe with small inner diameter, uniform wall thickness and no welded joint, which is mainly made by drawing, perforating or cold drawing process.

Oil well pipe corrosion is a very important technical and safety problem in the oil and gas industry.

Black low carbon steel pipe is a kind of steel pipe mainly produced by hot rolled or cold drawn steel material, and the surface is not galvanized, and the black oxide skin is retained.

Stainless steel is a special steel made by adding chromium and other metal elements to ordinary carbon steel.

As a common building material, the surface treatment process of stainless steel square pipe is very important to improve the corrosion resistance and aesthetics of stainless steel square pipe.

Stainless steel square pipe is a stainless steel material made of square or rectangular pipe, because of its excellent corrosion resistance and aesthetics, widely used in architectural decoration, industrial equipment, structural support and transmission systems.

Flange is a very important part of pipeline connection, it can usually affect the safety of the entire pipeline. After the flange is installed, regular cleaning and maintenance are usually required to prevent the flange from rusting and damage, resulting in leakage of the entire pipeline.

Stainless steel flanges are commonly used in connecting pipe systems. There are many types of them, and the material, standard, size and application of each flange are different.

Stainless steel is a kind of steel formed on the basis of ordinary carbon steel by adding at least 10.5% chromium and other alloying elements (such as nickel, molybdenum, vanadium, niobium, titanium, etc.).
