Spiral Steel Pipe Production Equipment

Spiral Welded Steel Pipe Production Line
Our six spiral welded steel pipe production lines can produce spiral steel pipes made of GR.A,GR.B and X42-X80 steel types with outer diameters ranging from 219.1mm to 3000mm and wall thickness from 5mm to 30mm.

LincolnWelding Machine
The Lincoln Welding Machine is produced by American Lincoln Electric Corporation featuring easy operation, rigidness and sturdiness. It has been widely used in pipeline welding, stainless steel welding, dual phase steel welding and Cr-Moheat resistant steel in many industries such as ship building industry. Over 112 years has passed since the Lincoln Welding Machine ventured into the welding and cutting industry and material manufacturing industry in 1985. It is now a pioneer in the international welding and cutting equipment manufacturing industry.

X-Ray Testing Machine
Nondestructive testing is a wide group of analysis techniques used to evaluate the properties and quality of our spiral welded pipes without causing damage. Common NDT methods include ultrasonic, magnetic-particle, X-Ray, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing, low coherence interferometry, etc. When a welded steel tube which has flaws is magnetized, magnetic flux leakage which is caused by the increase of the reluctance of the defective area will generate a partial magnetic field and the magnetic powder will indicate the shape and location of the defective area.

Off-line Welding Seam Ultrasonic Testing Equipment (for SSAW Steel Pipe)
The equipment can probe the defects of SSAW steel pipe with diameter ranging from 508mm to 3000mm, wall thickness from 6mm to 20mm and length from 6mm to 20mm.

Flat Head Chamfering Machine
This kind of chamfering machine can chamfer steel pipes with outer diameters ranging from 610mm to 3000mm, wall thickness from 8mm to 30mm, the yield point for the material from Q235 to X80 and length from 8mm to 20mm.

Hydraulic Pressure Testing Machine (Spiral SAW Steel Pipe)
The testing capacity of our Hydraulic Pressure Testing Machine is 3000 ton. The tested steel pipe should have an outer diameter ranging from 610mm to 2540mm and the wall thickness from 6mm to 30mm.

Other Products
    1. ASTM A252 Longitudinal Welded PipeOur longitudinal welded pipe is produced in accordance with the ASTM A252 Standard Specification for Welded and Seamless Steel Pipe Piles. During the manufacturing process for this range of ERW steel pipe, heat treatment, non-destructive test and hydrostatic test are not required.
    1. EN10219-1 Straight Seam Steel PipeOur EN10219-1 standard straight seam steel pipes are cold formed pipes with circular, square or rectangular cross sections. The special manufacturing technique for the ERW steel pipe eliminates the demand for heat treatment after pipe forming.
    1. Line PipesWe can offer two categories of line pipes: SSAW steel pipe and black steel pipe. By changing the forming angle, our range of API 5L line pipes can be made into various diameters while using raw materials of the same width.
    1. EN 10217-1 Black Steel PipeFabricated according to EN 10217-1 standard specification, this range of black steel pipe comes with circular cross section and is manufactured by using electrical resistance welding technique. It has passed both TR1 and TR2 tests.
