Detailed Photos

The spiral steel pipe is a spiral seam steel pipe with strip coil plate as raw material, often warm extrusion forming, and welded by automatic double-wire double-sided submerged arc welding process. The spiral steel pipe sends the strip steel to the welding pipe unit, and rolls up the strip gradually to form a circular tube blank with open gap through multi-channel roll rolling. The pressure of the extrusion roll is adjusted to control the weld gap between 1 to 3mm, and the two ends of the welding joint are flush.
 

Spiral tubes are mainly used in the following fields:
1. Tap water engineering: used for water supply, drainage, sewage treatment engineering, mud transport, ocean water transport, etc.
2. Petrochemical industry: used for liquid transportation, such as oil and natural gas transmission pipelines.
3. Chemical industry: for the transportation of liquids and gases.
4. Power industry: used for liquid and gas transmission.
5. Agricultural irrigation: used for water supply, drainage, etc.
6. Urban construction: used as piling pipe and bridge; Wharf, road, building structure pipe, Marine piling pipe, etc.
7. Transportation of gas, steam and liquefied petroleum gas.
Spiral pipe is a spiral seam steel pipe made of strip coil plate, extruded at constant temperature and welded by automatic double-wire submerged arc welding process. The advanced double-sided submerged arc welding process can realize welding in the best position, and it is not easy to have defects such as wrong edge, welding bias and incomplete welding, and it is easy to control the welding quality.
