Storage Requirements for Plastic-lined Composite Pipes

Plastic-lined steel pipes (including plastic-lined pipes) should be stored indoors in a straight and level position, away from heat sources. When stored outdoors, rain-proof protective measures should be taken, and they should not be stored for long periods in places exposed to direct sunlight or severe cold. The ambient temperature during storage of plastic-lined steel pipes (including plastic-lined pipes) should preferably be between -30°C and 45°C. When stacking plastic-coated steel pipes with an outer plastic layer, two layers of support pads with a width of 100mm should be used at the bottom. The number of stacking layers should comply with the regulations.
