Home » Products » Steel Pipe » Piling Pipe

In recent years, piling pipe is widely used in many fields and the diameter of this product is becoming larger and larger. According to the different needs of customers, we can provide quality product and services. Strip coil is the raw material and warm extrusion and automatic double wire-sided submerged arc welding process are used to manufacture this product. This product can be used as permanent load supporting tube for construction of bridges, roads, high-rise buildings and deepwater wharfs.

Detailed Specifications
Standard: ASTM A252
Grade of steel: Grade 1/Grade 2/ Grade 3

According to different manufacturing processes, piling pipe can be divided into HFW type, SMLS type, LSAW type and SSAW type.

(1) HFW Pipe
Size (outer diameter× wall thickness):
33.4 - 609.6mmX 2.1 -14mm
Hot rolled steel is the raw material and technique is HFW
(2) SMLS Pipe
Size (outer diameter× wall thickness): 13.7 - 609.4mmX 2.24-30.96mm
This product is manufactured by tube perforation, cold rolling and cold drawing.

(3) LSAW Pipe
Size (outer diameter× wall thickness): 325--1420mmX 6.0 - 18mm
JCOE forming, one weld and submerged arc welding process are used.
(4) SSAW Pipe
Size (outer diameter× wall thickness):
219--2220mmX 6.0 - 18mm

HFW type is heated and welded with 10-500KHZ high-frequency current. It has fast welding speed, small welding affected area and high-quality weld. SMLS type has no seam. With big wall thickness and strong pressure bearing ability, this product is a good choice for building piling. The manufacturing process of LSAW type is very flexible and many models with unique specification and wall thickness are available. Many of them are not available for the other three types. Low carbon structural steel or low alloy steel strip are turned into tube blank in molding angle to manufacture SSAW type piling pipe. After that, seam of tube is welded together. Narrow strip steel can be used to manufacture large diameter tube and the production process is simple, highly efficient and cost effective.
