    1. API 5L SSAW Steel PipeThe spirally submerged arc welding method makes sure all our spiral welded pipes have great roundness and straightness, thus allowing us to eliminate the pipe straightening process.
    1. GB/T 9711.1 HSAW Steel PipeDuring the welding process, the steel is heated by one or more electric arcs between the bare metal's consumable electrodes and the steel plate, thus achieving metallic bonding.
    1. GB/T 9711.2 Spiral Welded Steel PipeIt is typically manufactured in the following steps. Firstly, the steel belts or plates should be molded. Secondly, the joint edging zone should be padded by metals and finally, the joints should be welded.
    1. ASTM A252 Spiral Steel Pipe This range of spiral steel pipe conforms to the ASTM A252 standard. During its production process, heat treatment, non-destructive test and hydrostatic test are not required.
    1. EN 10219-1 SSAW Steel PipeThis range of SSAW steel pipe conforms to EN 10219-1 standard specifications. As cold formed pipe sections, our SSAW pipes eliminate the demand for heat treatment after forming.
    1. EN 10219-2 Welded Steel PipeThe maximum outer diameter for the spiral pipe is 3048mm and the maximum wall thickness is 30mm. The maximum length for a single welded tubing reaches 20000mm.
    1. EN10217-5 Spiral Welded Steel PipeOur EN 10217-5 spiral welded steel pipe can be either alloy steel pipe or non-alloy steel pipes. It is mainly applied as boiler pipes due to its great performance under high pressure and high temperature conditions.

Spiral Steel Pipes

Our welded steel pipes are made of GR.A, GR.B, X42-X100, H40, J55, K55, S195T, S235JRH, S355JOH, S355J2H, ST33, ST42, STK400, STK500, Q235 and Q345 steels.

Technical specifications
We can provide spiral steel pipes with outer diameters ranging from 219 to 3048 mm and wall thickness from 5.0 to 30 mm.

According to the forming process, the spiral steel pipe can be divided into external and internal controlled roll forming pipes. Physical and chemical inspections for the raw materials, welding wires and welding flux should be done before using them. Our spiral welded pipes are typically large diameter pipes.

The spiral steel pipe is ideal for the long distance transferring of water, petroleum, natural gas, coal gas and pulp, etc. Our welded spiral pipes can also be used in the chemical, electricity, irrigation, structural engineering and steel pile industries.

In addition to regular rust removal treatment, our range of steel spiral pipes also undergo other treatments to ensure water and fog resistance as well as scratch resistance.

A protector should be fixed on the end of the welded tube and a polythene wrapper is used for the head of the steel tube.

After-sales Service
We will answer all of our client's questions thoroughly and precisely. After-sales tracking service is also available for our customers.
