Slitter Line and High Frequency Pipe Mill Line

we supply straight welded pipe equipment, spiral welded pipe equipment, cold rolled forming section equipment, steel plate & steel pipe finishing equipment and high accuracy slitting and cross cutting equipment.

• Slitter Line - The slitter line is provided to slit the steel strip in certain width and thickness into several narrow strips in preset size, which are then rewinded into coils by the winder.

• Uncoiler - The uncoiler is a key unit in the mill line. It’s mainly used to support the strip coil together with the straightener, feed the strip into the flattener.

• End straightener - The end straightener is used together with the uncoiler. It leads the head of the strip out of the uncoiler, straightens it and feeds it into the flattener.

• Flattener - The flattener is located next to the end straightener. It’s used to flatten the head and trail of the strip and feed the strip into the shear welder.

• Shear welder - The shear welder is a key unit in the longitudinally welded pipe mill line. It’s used to paralleling cut the trail of the strip, which has just gone into the accumulator, and the head of the strip coming out of the uncoiled, and then welds them together with CO2 shield welding. It’s a typical unit of integration of machinery, electronics and hydraulics with reasonable design, compact structure, precise aligning and butt-welding and higher automatist.

• Accumulator - The accumulator is a strip-storing unit in the longitudinally welded pipe and formed section production. It stores certain amount of strip and leaves time for the shear welder to shear and weld the ends of the strips. The uninterrupted and fluent production is thus guaranteed. It’s one of the main machines in the modern pipe mill line and formed section line.

• Forming mill and sizing mill - The forming and sizing mill rolls the steel strip to pipe shape by roll forming or cage forming and welds it to longitudinal welded-pipe with high frequency induction (or contact) heating. The mill series (including formed section mill) feature advanced technology, reasonable structure, skilled manufacturing, attractive appearance, easy operation and convenient maintenance. The mills sell well all over China and have been exported to the America, Indonesia and Philippine etc.

• Flying saw - The flying saw is a key unit in the production of longitudinally welded pipe and formed section. It’s used to precisely cut the pipe to length automatically under the condition that the pipe continuously delivered from the mill at high speed.

• Pipe straightener - The pipe straightener is a finishing unit in the high frequency pipe mill line. It’s provide to straighten the pipe and eliminate the stress and bending occurred after the forming and welding.

• End milling and chamfering machine - The milling and chamfering machine is a key unit in the longitudinally welded pipe production line. It’s provided to mill the two ends of the welded pipe and chamfer the inner and outer edges. The whole on-line procedure is cyclically done automatically and continuously. It features reasonable design, compact structure, smooth traveling, reliable work, easy operation and convenient maintenance.
