1. The appearance of the storage and delivery of anti-corrosion steel pipes needs to be checked as follows:
①Check root by root to ensure that the surface of the polyethylene layer is flat and smooth, without dark bubbles, pits, wrinkles, and cracks, and the overall color needs to be more uniform. There should be no excessive corrosion on the surface of the pipe.
②The bending degree of the steel pipe should be less than 0.2% of the length of the steel pipe, and its ovality should be less than or equal to 0.2% of the outer diameter of the steel pipe. The surface of the entire pipe is partially uneven <2mm.

2. The transportation of anti-corrosion steel pipes needs to pay attention to the following points:
①Loading and unloading: The spreader that does not damage the nozzle should be used, and the anti-corrosion layer should not be damaged. All construction machinery and equipment must comply with regulations during loading and unloading. Before loading, the anti-corrosion grade, material, and wall thickness of the pipes should be checked in advance, and it is not advisable to mix them.
②Transportation: A thrust baffle should be set between the trailer and the cab. When transporting the anti-corrosion pipe, it is necessary to bundle it firmly and take protective measures for the anti-corrosion layer in time. Between the anti-corrosion pipe and the frame or column, and between the anti-corrosion pipe, a rubber plate or some soft material should be set for the lining.

3. What are the storage anti-corrosion steel pipes standards:
① Pipes, fittings, and valves should be properly stored following the instructions and should be checked during storage to avoid corrosion, deformation, and aging.
② There are also materials such as glass cloth, thermal tape, and heat shrinkable sleeves that need to be stored in a dry and ventilated warehouse.
③Materials such as pipes, fittings, and valves can be classified and stored in the open air. Of course, the selected storage site must be flat and free of stones, and there should be no standing water on the ground. The slope is guaranteed to be 1% to 2%, and there are drainage ditches.
④ The anti-corrosion pipes in the warehouse need to be stacked in layers, and their height needs to ensure that the pipes do not lose their stable shape. Stacked separately according to different specifications and materials. A soft cushion should be placed between each layer of anti-corrosion pipes, and two rows of sleepers should be placed under the lower pipes. The stacked pipes should be more than 50mm from the ground.
⑤If it is on-site construction, some storage requirements for pipes: two support pads need to be used at the bottom, and the distance between them is about 4m ~ 8m. The pipes and the anti-corrosion pipes should be padded with flexible spacers.
