300X300X16 mm Used Square Pipe Machine

300X300X16 mm Used Square Pipe Machine,the feeding direction of this machine is left feeding. The machine can process 120X120~300X300mm square tube and 100X150~200X400mm rectangular tube. The wall thickness of the tube is 5~14mm, and the maximum forming speed can reach 10~30m/min. The machine is new in composition, and the tube-making process mainly adopts the roller forming principle to directly form the square process technology to ensure the accurate production and forming.

Technological Process

300X300X16 mm Used Square Pipe Machine working flow:

Raw material (steel strip coil) → Coiling → Uncoiler → Head removal → Pinch leveling → Cutting head and tail → Butt welding → Pit accumulation → Vertical roller → Pinch roller → Pit accumulating → Vertical roller → Pinch roller → Forming welding and sizing machine (roll forming) → High frequency welding → Remove the burrs outside → Spraying cooling → Sizing machine → Straightening → Fixed length cutting → Run out table
