Precautions for seamless pipe loading
1. In order to prevent sinking, indentation, scratches and thread damage of the pipe body, it should be hoisted by disk crane, nylon belt or steel wire rope with protective spacer when loading.
2. When hoisting bundled steel pipes, no more than two bundles are allowed to be hoisted at the same time. When the weight of a single bundle exceeds 3000kg, only a single bundle is allowed to be hoisted.
3. It is not allowed to forcibly pull out the nylon belt or steel wire rope when it is pressed by the steel pipe or the pipe bundle. When loading wagons and delivering steel pipes for transportation to the user, due to the restrictions of the shipping conditions, the nylon belt or wire rope must be pulled smoothly to avoid strong collisions between the steel pipes or bundles or rollover of the bundles. Rough loading and unloading is strictly prohibited.
4. When using the tail hook to load and unload the pipe, the pipe end should be prevented from being damaged. It is required to pad cushioning material on the contact surface with the pipe end. During hoisting, there shall be no impact load sufficient to cause local bumping or loss of the pipe body or pipe end.
5. When using a forklift, the end of the forklift should be rounded and properly lined to minimize damage to the pipe.
Precautions for seamless pipe transportation
1. Railway transportation
1) The compartment should be clean and free of stones, bricks and other hard objects to prevent them from damaging the steel pipe.
2) When the casing and oil pipe (including casing and oil pipe bundles) are transported by railway trucks, sleepers or rough grass handles twisted by multiple straw ropes should be placed at equal distances along the length of the steel pipes at the bottom of the carriage (The diameter is ≥120mm, the height after the load is pressed down is ≥60mm, and the length cannot be shorter than the width of the carriage). In order to prevent the steel pipe from rolling left and right, and to avoid collision and friction with the carriage wall, more than two rough grass handles (diameter Ω≥120mm, length not shorter than the height of the carriage) should be placed between the casing pipe and the oil pipe and the carriage wall. Couplings must not be placed on sleepers or rough handles.
3) Under the condition that the length of the steel pipe is allowed, the steel pipes of each hoist are misaligned to the two ends of the carriage.
2. Trucking
1) The compartment should be clean and free of stones, bricks and other hard objects to prevent them from damaging the steel pipe.
2) For bulk or bundled steel pipes, sleepers should be placed on the bottom of the carriage. For vehicles using steel structure brackets for flatbed vehicles, protective rubber pads must be installed on the full length of the sides that are in contact with steel pipes.
3) When the steel pipe (or pipe country) is transferred and delivered to the warehouse in the factory area, the steel pipe (or pipe bundle) should be properly placed with isolation sleepers, at least two places along the length of the steel pipe. Skids should be level and sound.
4) For the finished steel pipes delivered to users for long-distance transportation, they should be bound firmly after loading. When bundling with steel wire ropes or chains, a protective spacer should be placed at the binding place of the steel pipes or a protective spacer should be installed on the steel wire ropes and chains to prevent damage to the surface of the steel pipes and avoid direct collision, friction and forward and backward movement between the steel pipes and the carriage.
5) When the steel pipes (or pipes) are transferred and delivered to the warehouse in the factory area, they should be shipped in batches strictly according to the furnace number (batch number).
6) Shakers must not be placed on sleepers.
3. Shipment and transportation
1) The steel pipes should be placed carefully in the cabin, and the support should be appropriate to prevent the steel pipes from rolling and moving due to the inclination of the hull. Avoid splices or pipe ends striking hatch edges, impacting hull railings.
2) Avoid stacking steel pipes where there is sewage or harmful chemicals or other corrosive media.
