Steel pipe will be induction heated, then transferred to shot blasting procedure. After dust removing check, steel pipe will be transported to pipe rack, where it will be put into epoxy powder coating line automatically.
Steel pipe will be heated again to enhance the adhesive force for epoxy powder. Powder coating, adhesive layer coating, PE layer coating will be finished gradually with a T shape equipment placement.
After PE layer coating, the whole pipe will be cooled by water, and sent into anticorrosion layer check (powder, adhesive layer, PE layer).
Finished pipe will be stocked in the warehouse for further usage. End beveling can also be done after this.
