Introduction to common materials of welded pipes

Introduction to common materials of welded pipes:

1. Carbon steel welded pipe
Carbon steel welded pipe is the most common welded pipe material. Its main components are carbon and iron, with the carbon content usually between 0.03%-0.08%. Carbon steel welded pipes are characterized by corrosion resistance, high strength and low cost. Therefore, it is widely used in construction, machinery, petrochemical and other fields. However, due to problems such as rust and pollution, carbon steel welded pipes require frequent anti-corrosion treatment, otherwise quality problems are likely to occur.

2. Stainless steel welded pipe

Stainless steel welded pipe is a kind of welded pipe material that does not rust and has high corrosion resistance. Its main components are nickel and chromium, of which the chromium content is more than 10.5%. The characteristics of stainless steel welded pipes are smooth surface, beautiful appearance, long life, easy to clean, etc. Stainless steel welded pipes are widely used in food, medical, pharmaceutical and other industries, especially in places that require high hygienic conditions.

3. Alloy steel welded pipe
Alloy steel welded pipe is a welded pipe material containing a variety of alloy elements. It is usually composed of alloy elements such as chromium, molybdenum, and manganese. The characteristics of alloy steel welded pipe are high hardness, high strength, high corrosion resistance, high temperature resistance, etc. Alloy steel welded pipes are widely used in chemical industry, construction, aviation, aerospace and other fields, especially in places that require high strength, hardness and corrosion resistance.

4. Galvanized steel welded pipe
Galvanized steel welded pipe is a welded pipe material with a layer of zinc coating on the surface of the steel pipe. Galvanized steel welded pipes have the advantages of corrosion resistance, beautiful appearance, and long life, and are widely used in construction, home furnishing, machinery and other fields.

In general, different welded pipe materials have their own characteristics and usage scenarios. In order to choose the welded pipe material that suits your needs, you need to make a selection based on the actual situation.
