Large Diameter Galvanized Steel Pipe Hot Dipped Galvanized Welded Steel Pipe

Product Description

Dimension high-frequency welding is a welding process in which the heat source used to melt the joining surfaces is obtained from high-frequency (HF) alternating current (ac) resistance heating.

The process begins with the cutting of the strip of the required size on slitting line and then fed through the Tube Mill for formation of line pipe. Once the formation of pipe is done, it is passed through the high frequency welder where the edges are welded together.

During the process of welding, because of immense generation of heat, there is formation of beads on both the edges, inside and outside the pipes. These beads are then cut in order to have unrestricted flow of fluid/gas inside the pipe.

Thereafter, pipes are cut into the required length and are transferred to finishing sections for further processing and testing of the line pipes like straightening, End Chamfering/Facing, Hydro-testing, Non-destructive Testing, Threading, Galvanizing etc., depending on the requirement of the customer.
