Manufacturer of welded pipe equipment

Founded in 1999, Shijiazhuang Great Wall Welded Pipe Equipment Co. Ltd is located in Shijiazhuang City, Hebei Province, which is a famous base of pipe mill industry in China. We are a high and new technology enterprise specialized in design, development and manufacture of welded pipe equipment，such as high frequency welded pipe line, ERW pipe mill line, precision pipe mill line, stainless steel pipe mill line, square and rectangular pipe mill line, cold roll forming equipment, slitting line, etc.

High frequency welding tube mill

High frequency welding tube mill is designed to make various shape pipes like square pipe, round pipe, oval pipe and other special shape pipes. The tube mill takes advantage of high frequency welding system and cold roll forming principle to make pipe from the thin sheet. The tube raw material could be various types like carbon steel, metal like Q235 and others.

Tube Mill Working Process:
{Steel Tape}→→ Single-arbor un-coiler →→Strip-head Cutter and welder→→ Spiral Accumulator→→Forming section(Flattening unit +Main driving unit +Forming unit +Guide unit +High frequency induction welding unit +squeeze roller)+ De-burr frame →→Cooling unit →→ Sizing unit and straightened →→Flying saw under computer-control →→ Run-out table→→straightening

High frequency working principle:
For welding part, it makes full use of two sciences-high-frequency current Skin-Effect and Adjacency Effect to make the current concentrate on the edge, then the temperature will reach to the point of welding. Then we can make the sheet to pipe by rolling and make the edge melting to one.

Forming and sizing machine

Forming and sizing machine is the main equipment in the steel pipe production line. It uses roll forming theory to coil long steel strip of a certain specification into pipe barrel without any intermittence and form longitudinal seam joint under the force of squeeze roller. And it uses induction welding to heat the longitudinal seam. That is, feed steel strip of a certain specification into the mill and coil it into pipe blank through forming roller.

Forming and sizing machine 

Then under skin effect and proximity effect of high frequency electric current. The current will be concentrated on the bond surface of the pipe fringe, welding it into tube blank quickly. After cooling, sizing and broad straightening, the needed pipe will be produced.
