SSAW steel pipe is the raw material of strip coil, often temperature extrusion molding, automatic double-wire double submerged arc welding process made of spiral seam pipe. Spiral steel pipe will strip into the pipe unit, the multi-roll rolling, strip rolled up, forming a circular gap opening gap, adjust the squeeze roll reduction, the weld gap control in the 1 ~ 3mm, and make both ends of the weld flush.


If any stock is there, it will be very good. because it is urgent for us.

                                                                                                                                                               ___Chelsea (Iran)

Nice quality, Nice logistics.

                                                                                                                                                               ___Malory (Czech Republic)

Price is very cheap.

                                                                                                                                                               ___Kerwin (Egypt)

Good quality, but if the pipes are with paint, it will be better.

                                                                                                                                                                ___Jason (South Africa)

Delivery is very timely.

                                                                                                                                                                ___Pulitzer (Peru)
