  • Product description: SP32 (diameters 13-50mm) welded pipe making machine china is for 13-50 mm diameters round tube,40x40mm square tube,30x50mm rectangular tube,thickness is 0.6-2.0mm based on welded pipe making machine.

SP32(13-50mm) welded pipe making machine china is a series of pipe making 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 then be sent into the weld box where the pipe is welded by a high frequency or solid state welder. The welded pipe making machine, 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.

Step 3: Strip Accumulator

Function: storage strip to keep continue production.

2 Types: Horizontal / Vertical

Advantage: Horizontal type can be larger storage. Vertical type is much cheap and small space occupied.
