Spiral welded pipe equipment (spiral steel pipe equipment) is a type of equipment that uses strip steel coils as raw materials, often formed by warm extrusion, and uses automatic double wire double-sided submerged arc welding process to weld and manufacture spiral seam steel pipes. Intermittent spiral steel pipe equipment refers to the process of directly placing strip steel coils into the uncoiler of the spiral steel pipe equipment for welding production, because the equipment must be stopped for steel plate docking when the coils are placed, So this form of spiral steel pipe equipment is called intermittent welding spiral steel pipe equipment. The spiral steel pipe equipment produced by our company has a nationally recognized energy-saving and environmental protection patent certificate. It is a new generation of energy-saving spiral steel pipe production equipment and a model of energy-saving in the field of steel pipe equipment in the 21st century.

Spiral welded pipes have low cost, excellent quality, and fast production speed. At present, preliminary progress has also been made in some special application directions, such as pier piling, tank welding (oil tanks, boilers, etc.), civil air defense engineering, air ducts, drums, steel structure support, pipes for high-rise building pile foundations, bridge type filter pipes, large diameter spiral circular variable square pipes, and so on. Spiral welded pipes are gradually being accepted by more and more industries due to their low cost, high level of production automation, and simple equipment structure. They will have great potential for development in the future.
The spiral welded pipe unit is used to open and level the steel coil through the unit equipment, and then feed it into the forming machine at a certain angle. It utilizes the principle of a three roll circular rolling machine, supplemented by a certain angle, to form a continuous circular pipe. The continuous spiral weld seam is welded using a submerged arc welding machine.
1. What other uses does spiral welded pipe have in water supply engineering besides traditional oil pipelines?
Spiral welded pipes have low cost, excellent quality, and fast production speed. At present, preliminary progress has also been made in some special application directions, such as pier piling, tank welding (oil tanks, boilers, etc.), civil air defense engineering, air ducts, drums, steel structure support, pipes for high-rise building pile foundations, bridge type filter pipes, large diameter spiral circular variable square pipes, and so on. Spiral welded pipes are gradually being accepted by more and more industries due to their low cost, high level of production automation, and simple equipment structure. They will have great potential for development in the future.
2. What are the difficulties in on-site construction of spiral welded pipe equipment?
The spiral welded pipe unit can be disassembled as a whole or in sections, with a simple structure and convenient installation. Infrastructure construction can be tailored to local conditions according to on-site facilities. In the future, the spiral welded pipe unit will enter a construction site production mode, greatly reducing engineering costs.
3. What is the diameter range of spiral welded pipe equipment that can accommodate?
welded pipe equipment can be produced separately from φ 325mm to φ 3620mm, with one machine in hand, worry free production
