Spiral Steel Welded Pipes - 406 Mm To 1626 Mm Diameter, 5 Mm To 25 Mm Wall Thickness | High-speed Spirally Welded, Conforming To Is 3589: 2001, Ap-5l, Astm

Hi-Tech specializes in manufacturing of Spiral Steel Welded pipes covering a range from 406 mm to 1626 mm diameter with wall thickness ranging from 5mm to 25mm conforming to IS 3589: 2001, IS: 5504, AP-5L, ASTM.

Pipe Process:
The raw material used in manufacture of Spiral SAW is H.R. Coil. It is continuously formed to require the specific diameter of the pipe, spirally welded at high speed and cut to required length. The following operations are carried out when the material is loaded for making of the pipe.

Entry Line :- Here the coils are opened, edge milled to required width and fed to forming stand at uniform speed. This unit also enhances the joining of the tail-end of the out going coil with the leading end of the incoming coil to produce continuous strips. Before initializing new campaign, entry line will be positioned in an angle, called Helical Angle in respect to the normal of forming table center axis.

Forming Stand :- The unit performs as the heart of the mill. Here the strip is formed to required size of the pipe & spirally welded.

Exit Line :- The main purpose of exit line is to give proper support to the pipe during forming, cut the pipe to required length and eject it outside.

The pipe is then visually inspected thoroughly, both in & out side/
