Spiral Steel Pipe

Spiral steel pipe is a type of welded pipe formed by spirally rolling a steel coil into a cylindrical shape and welding the seam along the spiral joint. The production process uses a continuous forming method, where the steel strip is fed at an angle to create the desired pipe diameter.

Spiral Steel Pipe Manufacturer in China-Hongkehua

Spiral steel pipe is manufactured using the Submerged Arc Welding (SAW) process, specifically:

SSAW: Spiral Submerged Arc Welding – both inside and outside welds are applied to ensure strong seam integrity.
The spiral angle can be adjusted to produce pipes of various diameters from the same width of steel coil.

Features of Spiral Steel Pipe

Wide Diameter Range: Typically available from 219 mm (8 inches) to over 3000 mm (120 inches) in outer diameter.Flexible Wall Thickness: Can be produced in various thicknesses depending on application requirements.Cost-Effective: Compared to longitudinally welded (LSAW) or seamless pipes, spiral pipes offer lower production costs, especially for large diameters.High Strength: The spiral weld distributes stress evenly, providing good structural integrity under pressure.

Advantages of Spiral Steel Pipe

Spiral steel pipes can be manufactured into ultra-large diameter pipes, with flexible production and adjustable lengths as needed. They have low material loss and lower overall cost. The spiral weld seam disperses stress, providing excellent resistance to water pressure and ground subsidence. Various anti-corrosion processes can be applied to the outer wall. They are widely used in large-scale buried pipeline networks, with large supply volume and mature construction matching pipe fittings. They offer outstanding overall cost-effectiveness for large-scale water conservancy and long-distance oil and gas transportation projects.

Application of Spiral Steel Pipe

Oil and Gas Transmission: Long-distance pipelines for crude oil, natural gas, and refined products.
Water Supply and Drainage: Large-diameter water transmission mains and irrigation systems.
Structural Piles: Foundation piles for bridges, high-rise buildings, and port constructions.
Slurry and Dredging Pipelines: Transporting sand, mud, or mining tailings.
Industrial Uses: Cooling water lines, ventilation ducts, and support structures.

FAQ

How to choose between spiral welded pipes and straight seam welded pipes?

For large-diameter, low-pressure fluids and pile foundations, spiral welded pipes are preferred; for medium and small-diameter, high-pressure oil and gas and high-temperature pipelines, straight seam welded pipes are recommended.

What is the pressure-bearing capacity of spiral welded steel pipes?

Thick-walled spiral welded pipes have good pressure-bearing capacity and are suitable for water supply and drainage, and medium and low pressure gas transmission. For high-pressure long-distance transmission, flaw detection is required.

Can spiral welded steel pipes be coated with 3PE anti-corrosion?

Absolutely. Most buried anti-corrosion spiral welded pipes on the market are equipped with a 3PE external anti-corrosion layer to extend their service life underground.

Are spiral welds prone to cracking and leakage?

All finished products undergo hydrostatic and flaw detection tests. The weld strength of qualified products is equivalent to that of the base material, and they are not prone to cracking under normal use.

Can spiral welded pipes be used for pile foundations?

Yes, they are very suitable. They are widely used in bridge construction, foundation piling, and foundation pit support casings, offering a much higher cost-performance ratio than seamless steel pipes.
