North Star’s new 8,000m² workshop and raw materials yard was
completed in summer 2014.
We have the capability to manufacture Blast Pipe from 89 to 340mm,
with 2015 capacity targeted at 3,000 pipes.
Pipes up to 140mm may be friction welded or submerged-arc welded;
from 152mm up, the pipe bodies and tool joints are shrink-fitted and
submerged-arc welded on one of our two SAW machines.
We implement 100% magnetic particle testing of the weld area.
Tool joints are subjected to both ultrasonic flaw testing and magnetic
particle inspection.
