It can produce large diameter steel pipe with narrow strip steel. The specifications are expressed by outer diameter * wall thickness. The welded pipe should meet the requirements of hydraulic test, tensile strength and cold bending performance of the weld .
Test sequence of helical welded pipe unit LH-400 1, motor and hydraulic motor idling test, check whether the spin direction is correct. 2. The single test run time is 2 hours. 3, reducer gear transmission smooth, sound normal, good lubrication, no oil leakage phenomenon. 4.
The leveling roller and delivery roller rotate normally, and there shall be no channeling phenomenon. 5. The oil cylinder and pipe joint of the hydraulic system shall not leak oil during the test run. 6.
Process operation and instructions: 6.1 Process description of spiral welded pipe Unit LH-400: Winding up → unwinding → primer leveling → Manual vertical roller → shear butt welding → manual vertical roller → Delivery → Prebending guide plate → Forming → external welding → Output → cutting → pulling out 6.2 Operation Instructions: The strip coil is hoisted on the lifting frame of the winding trolley by the crane, and the hook is removed.
The trolley moves horizontally and sends the strip coil to the cone head of the uncoiler. The oil cylinder of the cone head of the uncoiler tightened the steel coil. The trolley lift is lowered back to its original position. After tightening the strip coil. Press the roller on the upper part of the strip steel coil, d
