Steel pipe storage, loading and unloading and steel pipe layout
1) Storage and transportation of steel pipelines
All kinds of steel pipes should generally be concentrated in a site that is a certain distance away from the construction road. When storing the pipe, support must be added under the pipe to ensure that it will not fall into the soil, and the distribution of gravity must be considered to prevent the pipe from being flattened or deformed. Also, pay attention to the corrosion protection of the inner and outer surface of the pipe groove. Reserve a certain amount of clearance needed to facilitate the passage of people, livestock, and wild animals. When arranging these pipes in place, it is also easier to call them out in order during delivery. After the pipes are manufactured in the pipeline manufacturing plant, they must be transported to the construction site through various methods. Special attention must be paid to the protection of the pipelines during transportation. Generally, the pipes have been treated with corrosion protection in the pipeline manufacturing plant. Failure to pay attention may cause damage to the anti-corrosion layer of the pipeline, especially where it is in contact with the suspension cable and the joints are easily scratched. Special precautions should be taken to prevent damage to the steel pipe and its anti-corrosion coating. Pipelayers and trucks equipped with side booms or other lifting equipment are generally used to load and unload pipes. When loading and unloading the pipe, the appropriate hook must be carefully selected, and the hook must be hooked on the cable tied to the pipe for lifting. The design and size of the hook must be able to distribute the lifting pressure well. When loading and unloading extra-heavy pipes, the brace should be installed between the cables to reduce the horizontal component of lifting. Also, it should be noted that when transporting pipes that have been coated with anti-corrosion coating, the beam on the truck should be wide enough to support the pipe correctly, and a cushion should be added between the fastening chain for loading and the anti-corrosion pipe. Care must be taken to prevent denting, flattening of the pipe, or other damages during all loading and unloading of the pipe. These measures include adding rubber or suitable material pads between the steel pipe and the suspension chain and covering the steel pipe with gaskets and tarpaulins. Note that pipe routing cannot be carried out before the completion of the blasting of the pipe trench. The transportation and unloading of pipes in extremely uneven areas or mountainous areas are not an easy task. Other methods must be used to transport the pipes in places, such as special overhead suspension cables or helicopters for pipe transportation and pipe deployment.
2) Steel pipe
The distribution of the steel pipelines in sequence according to the design consumption of the pipeline in this section is the pipe layout operation. Generally, the placement direction of the steel pipeline should have a certain slope with the pipe trench or construction line, so that it can be distributed within a certain range. Putting the prescribed number of pipe sections reduces the floor space while leaving a certain working area for construction workers and equipment. At the same time, it pays attention to notices to the surrounding public and leaves convenient and fast access roads. The pipe-laying team shall be equipped with cranes, pipe hangers for pipe-laying, steel pipe transport vehicles, tractors, passenger and cargo vehicles, and transport vehicles and various equipment for construction personnel. The number of transport trucks depends on the distance of the pipes and the requirements of the day's operations. Special transport vehicles should be used for transportation in muddy areas. Try to avoid damaging the steel pipe and its anti-corrosion coating during the pipe laying process. If damage occurs, the damage location should be marked. Use appropriate pipe end hooks for loading and unloading to prevent damage to the groove. Accurate placement of steel pipes with different wall thicknesses and grades according to design requirements. It is not allowed to drag the steel pipe on the ground when laying the pipe.
