HTS

 
 

PSL, apart from having ten conventional H-SAW Pipe Mills, has added to its fold, a state of the art HTS Pipe Mill with an installed capacity of 3,00,000 MT/annum.


In general, the capacity of conventional H-SAW Pipe Mills are limited by the speed of SAW process. One conventional H-SAW Pipe Mill has a nominal installed capacity of 75,000 MT/annum. To overcome this capacity limitation the latest High Speed Two Step Technology has been adopted wherein the Pipe Manufacturing process is split into the two following steps :


In the first step, Pipe Forming and Tack Welding is down with a welding speed of upto 10 mtrs/minute.

In the second step, ID and OD/SAW (Submerged Arc Welding) is carried out on three Off-line Welding Stands. Each stand is designed to weld upto 2.5 mtrs / minute.

This new HTS-SAW Pipe Mill has been set up with active collaboration of two leading German Companies, PWS & ISAM.
