Matching: will be matched with industrial pipe making machine.

Component: inside and outside weld seam leveling equipment, hydraulic air control system, automatic electric hydraulic air control system with PLC, hydraulic cycling equipment for mold and roll.

With four pillar structure, the rollers could press the tube bead more evenly and stable. This model is especially suitable for making precision industrial pipe, with high performance.

Function:  stainless steel welded pipe welding leveling device and a built-in SKD11 mandrel and utilization of stainless steel welded pipe rolling device automatic reciprocating roller, through the control to achieve the strength and make stainless welded pipe and weld leveling, completely remove the internal and external welding and with more respect to seamless requirement.

Comparing with the normal type, this model could adjust the whole rolling trolley according to the position of pipe’s welding seam. It is more flexible.

Working procedure: with more than the high and weld stainless welded pipe after level after rolling roll over, high removed, welded pipe section into a level in welding rods, elliptical stuck pipe welded pipe, followed by vertical roll rolling, welded pipe section into a mandrel, with full welded pipe separation in the frame of the cylinder back to when proper place, then the second rolling cycle.

After the internal weld is leveled, the stainless steel welded pipe has smooth inner and outer walls. After polishing to a certain extent, it can be used for high-end industrial applications such as sanitary fluid pipes, water pipes, heat exchange pipes, oil and gas pipelines, etc., and can also be widely used in food. Industry, petroleum industry, pharmaceutical and chemical industry, sanitary ware industry, etc.

Some people may have questions: whether the welded pipe can be polished directly without internal flattening. The answer is: no! Without the inner flattened welded pipe, or the flattening effect is poor, the number of internal and external polishing will be increased, which directly affects the thickness of the finished pipe, so that the pipe wall tolerance becomes larger and the weight is reduced. Indirectly increases production costs and harms the interests of manufacturers.
