Spiral steel pipes are widely used in the engineering field because of their special structure and superior performance. According to its structural characteristics, it has two main uses:

Liquid delivery:

Water supply and drainage: Spiral steel pipes are widely used in water supply and drainage systems. Its structure is stable, able to withstand the pressure of liquid, and due to its superior anti-corrosion properties, it can be used to transport clean water and sewage for a long time.

Chemical substance transportation: Due to its superior anti-corrosion properties, spiral steel pipes can be used to transport chemical substances, such as gas, oil, etc. This makes it an important transmission pipeline in the petrochemical industry.

Structural purpose:

Piling pipe: Spiral steel pipe can be used as piling pipe for pile foundation construction in foundation projects. Its high structural strength and ability to withstand vertical loads make it an ideal material for piling.

Bridges and Building Construction: Spiral steel pipes can be used as support structures for bridges and as pipes in building structures. Its high strength and stability make it suitable for applications where it bears various structural loads, such as bridges, roads, docks, etc.

Other applications:

Urban construction: Spiral steel pipes are also widely used in urban construction, such as in the construction of roads, pipelines, and other infrastructure.

Electric power industry: It can be used in transmission towers, cable protection tubes, etc. in the electric power industry.

Non-destructive testing: Spiral steel pipes require non-destructive testing during production and use to ensure their quality and safety. Flaw detection methods include radiographic flaw detection, penetrant flaw detection, magnetic flaw detection, etc.

Strength inspection of pressure vessels:

Hydrostatic test and air pressure test: used to test the sealing and strength of welds under pressure of pressure vessels and pipelines. Hydrostatic testing and air pressure testing are common methods to ensure the safety and reliability of containers under working conditions.
