Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip after being coiled and formed, generally fixed length 6 meters. The production process of welded steel pipe is simple and the production efficiency is high.

Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Welded steel pipe with hot-dip or electro galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.

Stainless steel square pipe is a hollow long strip of steel, because the section is square, so it is called square pipe. A large number of pipelines used to transport fluids, such as oil, natural gas, water, gas, steam, etc., in addition, when the bending resistance and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures.

Seamless rectangular tube is a long steel strip with a hollow cross-section and no seams around it. The inside of the pipe is hollow and has a certain cross-sectional area, which is widely used as a pipeline for conveying fluids, such as pipelines for transporting oil, natural gas, gas, water, and certain solid materials

Galvanized square pipe is a kind of hollow square section steel pipe with hot rolled or cold-rolled galvanized strip or galvanized coil as billet after cold bending processing and forming and then made by high-frequency welding, or the cold-formed hollow steel pipe prepared in advance and then processed by hot dip galvanizing.

Galvanized steel pipes are divided into cold galvanized steel pipes and hot galvanized steel pipes. Welded steel pipe with hot-dip or electro galvanized coating on the surface of galvanized steel pipe. Galvanizing can increase the corrosion resistance of steel pipes and prolong their service life.

Specially shaped seamless steel pipes are a general term for seamless steel pipes with other cross-sectional shapes except for circular pipes. According to the different cross-sectional shapes and sizes of steel pipes, they can be divided into seamless steel pipes with equal wall thickness and irregular shapes
