Non Oiled Large Diameter Spiral Steel Pipe SSAW Tube For Drilling Construction
Large diameter spiral steel pipe tube SSAW steel pipes for drilling construction
Spiral welded pipe.
by welding with an automatic double-wire submerged arc welding process. The spiral steel pipe feeds the strip steel into the
welded pipe unit, and after being rolled by multiple rollers, the strip steel is gradually rolled up to form a round tube blank
with an open gap. 3mm, and make the two ends of the welding port flush.
Main Application:
1. Piling pipe;
2. Construction;
3. Water, Oil, Gas transportation;
