SP273(165-273 mm) machine tube mills china is a series of tube mills 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 machine tube mills then be sent into the weld box where the pipe is welded by a high frequency or solid state welder. The tube mill china be formed to expected shape (round/ square/ rectangle etc) or size in a sizing machine. Finally the tube mill china will be cut to length and bundled.

2. Process flow of machine tube mill china

pipe making machine, pipe welding machine

Step 1: Uncoiler Function: support rolled plate and strip tension for tube mill china, by the frame, main shaft, increases of drum, brake. There are 3 types: pneumatic, hydraulic and manual.
Step 2: Shear & Butt-welding Function: Shear the end of each strip coil, then welding them together, so that machine tube mills tube mill china can be continue production. 2 Types: Automatic & Manual
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.
Step 4: Forming Section Function: forming the machine tube mill china from strip Advantage: >Advanced forming technical >One-stage molding platform >Reliable quality gear box >Siemens Beide motor
Step 5: High Frequency Welding Function: Welding the pipe , different thickness & diameter, the power of the HF machine tube mills welder Our advantage: We choose the machine tube mill China best welder: Sanyi brand.
Step 6: Sizing Section Function: sizing the machine tube mill china to precise size Advantage: >Advanced sizing technical >One-stage molding platform >Reliable quality gear box and Siemens Beide motor >High precision, low error of the machine tube size
Step 7: Flying saw / Cold Saw Function: cutting the machine tube mills tube to right length. Fly saw: easy to operation, low investment. Cold saw: no noise, no burr cutting precision and cross section.
Step 8: Run Out Table. Function: run out the pipe, packing the pipe for machine tube mill china Type: Automatic or manual
