Because of their own advantage of our products,highly praised by our customers around the world.
K45/50/60 precision high frequency longitudinal welded pipe production line / pipe making machine / tubemill is designed to produce welded pipes of 13-90mm in OD and 0.8mm-3.0mm in wall thickness, as well as corresponding square and rectangular pipe.
Application Products: GI, carbon steel and stainless steel tubes for metallurgy, construction, transportation, machinery and vehicle industries.
√ High production efficiency, line speed can be up to 120m/min.
√ High yielding, the machine works stably at a high speed, which improves the yielding of products.
√ Low wastage, low unit wastage and low production cost.
√ High accuracy, diameter error is only 0.5/100 of the pipe OD.
