Steel roll forming machine /pipe forming machine
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.
Steel roll forming machines sizes:

Please choose the proper machine according to your material thickness.
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.
HF Welder technology has the following features:
1．It supports many kinds of material like carbon steel, GI and others.
2．One machine could make a large range of pipe sizes by changing mold.
3．One machine could be used to make square pipe, round pipe by changing mold.
4．High working efficiency but low energy consuming: the power is 200KW TNGP.
5．The pipe made by this kind of machine could be used in many areas like water tube, wire pipe and others.
