Straight seam high frequency ERW pipe tube mill

Straight seam high frequency ERW pipe mill/tube mill

Straight seam high frequency ERW pipe mill/tube mill is specially used for producing Φ10-Φ200mm, δ 0.4-6.0 mm high-frequency straight seam welded pipe and corresponding square pipe (17*17-62*62mm,1.2-3.0mm). The composition of equipment is from uncoiler to fixed length cutting saw. Rolling speed can be according to suitable range of pipe diameter and wall thickness.

Work flow of HG32 Small pipe welded pipe machine:

Raw material (steel coil) → uncoiling → non-power leveling →roll forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → cutting → run-out table

HG32 Small pipe welded pipe machine Working Principle:

For welding, 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.

This 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.
