Warehouse management and hoisting precautions for spiral welded pipe factory

Warehouse management and hoisting precautions for spiral welded pipe factory:

1) Matters needing attention in storage management of spiral welded pipes

1. The foundation on which steel pipes are stacked should be higher than the ground level to ensure that part of the steel pipe body is not immersed in water due to rain.

2. Stacking height: Stacking too high can easily deform the roundness of steel pipes, affecting delivery and use.
In particular, D/T (pipe diameter/wall thickness greater than 150mm) steel pipes with a diameter above 1220mm must not be stacked in more than 2 layers;
Steel pipes with a diameter of 820mm-1020mm must not be stacked in more than 3 layers;

Other specifications can be stacked according to site requirements.

3. After the steel pipes are stacked, clamps should be placed on the outer steel pipes to prevent accidents caused by rolling steel pipes.
4. Anti-corrosion: If there are corrosive liquids and gases near the storage place or there are companies that use or manufacture such products nearby, the stored steel pipes will corrode and should be protected with rainproof cloth.

2) Precautions for hoisting spiral welded pipes

1. The lateral contact surface between the hook and the end of the spiral pipe shall not be less than 40mm, otherwise it will easily deform the pipe mouth and affect the pipe docking.
2. Limitation on the number of hoisting rods

With diameters of 219mm, 273mm, 325mm and 377mm, up to 4-5 pieces can be hoisted at one time;
With diameters of 426mm, 478mm and 529mm, up to 2-3 pieces can be hoisted at one time;
Up to two steel pipes with diameters of 630mm and 720mm can be lifted at one time; steel pipes with diameters above 820mm can be lifted with one piece at one time.
