All the anti-corrosion pipelines must pass the factory inspection, when the pipes delivered to the specified address, the transportation management staff and the reception staff check coated pipes and fill out the view record. Serious damage to the coating of the tube should be shipped back to the preservative precast plant.
Anti-corrosion pipe is transported by special vehicle and the bottom of vehicle chooses thickness not less than 15mm rubber sheet having a width of not less than 100mm in order to reduce the impact of abrasions. Transport of vehicles must be restricted avoiding sudden braking to prevent pipe displacement or damage to the coating.
Loading and unloading pipes using crane or pipelayer. Coated pipes handling should use special harnesses with hanging and dropping gently. In the contact surface pad soft material avoiding bump and should pay particular attention to orifice protection. The angle between corrosion-resistant pipes and the slings should not less than 30°in the hoisting process.
Corrosion-resistant pipes stacking height of not more than three layers stack pipe support to the tube in the center stack prevail, symmetrically arranged, the distance from the ends of the pipe end support for 1.2-1.8m, pipe pile supporting two pipe both sides of the crib wedge should be set to prevent the roller tube.
The strapping material to avoid damage of pipeline coatings as the standard when transport vehicles transporting pipe. Prohibit wirerope directly tied steel pipe and use nylon strapping. strapping tools parts touching the tube pad a soft material to avoid damage of pipeline coatings.
