Spiral Welded Steel Pipe Manufacturer | China SSAW Steel Pipe Supplier

china spiral welded pipe manufacturer and supplier

SSAW (Spiral Submerged Arc Welded) Steel Pipes, also known as spiral welded pipes, are produced through a continuous spiral welding process using hot-rolled steel coils, followed by submerged arc welding for superior weld quality.

These pipes, often exceeding 20 inches in nominal pipe size (NPS), are highly customizable, supporting large diameters and extended lengths to meet diverse project needs.

SSAW pipes can handle high pressure and tension. They work well for transporting liquids, gases, and fluids. These pipes are used in municipal water and wastewater systems, oil and gas, petrochemical, and urban construction.

Spiral Welded Pipe Manufacturing Process

Spiral welding technology is a long-standing and efficient technology and is still one of the most reliable methods for producing high-quality pipes. The first step in manufacturing spiral welded steel pipes is to select high-quality steel coils, roll the steel coils into spirals and feed them into the welding station. Using submerged arc welding, the edges of the pipes are welded together to form a strong and durable weld. After that, the pipe size is precisely adjusted. This streamlined process facilitates the production of low-cost spiral welded pipes.

Applications of UNIASEN Spiral Weld Pipe

Spiral welded pipes are suitable for large diameter pipelines and have excellent pressure and corrosion resistance. It is essential for transportation and infrastructure projects in many industries, including piling. SSAW pipes are not only used in structural engineering, but also in water, slurry and dredging pipelines, providing reliable performance in harsh environments.

what is spiral welded pipe?

Spiral welded is made by rolling strips of steel into tube-like shapes. Then, the ends are welded.

The process involves forming the steel strip into a spiral shape and welding the seam. This welding technique makes the pipe strong and reliable. It does so by keeping the weld even and unbroken.

Spiral-welded pipes are made by coiling steel plates into a spiral shape. Long weld seams join them together. This is different from seamless pipes and LSAW pipes.

SSAW Pipe VS LSAW Pipe

Both these pipes are SAW (submerged arc welding) pipes. But their way of manufacturing along with structures are different.

For SSAW pipes, the steel coils are shaped into a spiral form, which results in a helical seam. While LSAW pipes are manufactured by bending steel plates into a cylindrical form, and then welded. This makes them a great option to be used for high-pressure applications.

Both these types of pipes are effective, and are used for the transportation of oil and gas.

SSAW Pipe

Cheap option
They’ve a spiral shape
Highly efficient
The outer diameter spans from 20 inches to 100 inches
Mainly used in construction
Tthickness tolerance is moderately precise

LSAW Pipe

Expensive compared to SSAW pipes
Welded longitudinally
Production efficiency is quite low
Outer diameter ranges from 16 Inch To 60 Inch
Used for medium/high pressure applications
Thickness tolerance moderately precise
High geometry accuracy
