RT16, RT25, RT32, RT45 high precision Carbon Steel Tube Mill, forming, welding and sizing parts share the same base, with better accuracy.
RT16,25,32,45 Carbon Steel Tube Mill is a series of machines that builds longitudinal weld seam pipe with steel strips of certain width. It starts by uncoil and flatten the slit steel coils into steel strips. The flattened steel strips will be inserted into the forming machine and the rollers in the machine will bend the strip to a round pipe shape. The round pipe will then be sent into the weld box where the tube is welded by a high frequency or solid state welder. The welded pipe will be formed to expected shape (round/ square/ rectangle etc) or size in a sizing machine. Finally the pipe will be cut to length and bundled.

RT530×13 high-frequency longitudinal welded pipe production line is mainly used for the production of round pipe φ219~φ530mm, wall thickness 4.0~13.0mm, square tube 170×170 - 400×400mm, wall thickness 4-10mm, and rectangular tube 260×130 - 400×200mm, wall thickness 4-10mm.
It adopts high-frequency induction welding and straight seam welding. Its working principle: weld the edge of the pipe when heated in a magnetic field, and then compress the edge in automatic mode, and the pipe moves continuously along the production line.

We can supply the rolls (together with the spacers, clamps, and sample plate) for the tube mills or for roll forming machines for the customers if get the drawings of the rolls. With our abundant experience and mature technology, we can also make the drawing according to some parameter information of the machine.

Square & Rectangle pipe mill is the special equipment to produce square and rectangle steel pipe. This equipment adopts the multipoint bending combined-type forming technology. One set of mould can produce all size of square and rectangle pipe. Compared with the traditional technology, the produce will have a good appearance, a good angle; share one set of mould, can cut down the cost of the machine, shorten the time of adjusting the mould; decrease the forming resistance, lighten the mould wear, reduce the load of power utilization.

Tube Mills can be complemented by a cassette system allowing the quick tooling change during profile production.
The cassettes are moved inline and offline by lifting.
