When confronted with the issue of storing anticorrosive steel pipes, many people undoubtedly share similar concerns. Below, let's delve into the specifics of how to store these pipes effectively.
Inspection Criteria for Inbound and Outbound Anticorrosive Steel Pipes:
① Individual Examination: Ensure that each pipe's polyethylene coating is smooth, with no hidden bubbles, pits, wrinkles, cracks, and an even color tone. The pipe surface should be free from excessive rust.
② Dimensional Checks: The pipe's bend should be less than 0.2% of its length, and the ovality should not exceed 0.2% of the outer diameter. Ensure that any localized surface irregularities are less than 2mm.
Transportation Considerations for Anticorrosive Steel Pipes:
① Loading and Unloading: Use lifting equipment that does not damage the pipe ends or the anticorrosive layer. Ensure all construction tools and equipment comply with regulations during loading and unloading. Verify the anticorrosion grade, material, and wall thickness of pipes before loading to avoid mixing different types.
② Transportation: Install thrust blocks between the trailer and the cab. Securely tie down the pipes during transport and promptly apply protective measures to the anticorrosive layer. Place rubber sheets or soft materials between pipes, and between pipes and the frame or supports.
Storage Standards:
① Proper Handling of Pipes, Fittings, and Valves: Follow the manufacturer's instructions for storage. Regularly inspect for rust, deformation, and aging.
② Special Storage for Materials: Glass cloth, heat-shrinkable tapes, and sleeves should be kept in a dry, well-ventilated warehouse.
③ Outdoor Storage: Pipes, fittings, and valves can be stored outdoors in a flat, stone-free area with good drainage (slope of 1% to 2% and drainage ditches).
④ Stacking in Warehouses: Stack anticorrosive pipes in layers, ensuring stability. Separate pipes by specifications and materials. Place soft pads between layers and under the bottom layer (supported by two rows of sleepers), keeping the bottom pipes at least 50mm above the ground.
⑤ Onsite Storage Requirements: During construction, elevate pipes using supports spaced approximately 4m to 8m apart, ensuring a minimum clearance of 100mm from the ground. Place flexible separators between supports, pipes, and among pipes themselves.
