Large -caliber straight steel pipes, as the core component of natural gas, oil, chemical industry and other fields, are important to install. Because of its large diameter and heavy weight, every link needs special attention during the installation process.
Before starting the installation, you must first prepare the installation area. For flat treatment of sand soil, the sand cushion layer is compacted with a flat plate to ensure its flatness, height, thickness, width, and density. Subsequently, the inspection of the straight -seam steel pipe passed through qualified certification to ensure that its quality meets the standards.
During installation, it is necessary to ensure that the hanging process of the straight steel pipe is safe. Use hanging cables or dedicated tools to avoid collisions during transportation and storage. Each steel pipe should be fully protected and fixed during transportation.
When the steel pipe is placed in the lower part, you need to check the bottom of the groove and the position of the pipe joints and pipes to ensure its accuracy. During the decentralization process, it should be avoided to accelerate or stop suddenly. Instead, two cranes need to be worked together to use a high -strength nylon belt to cover the tube and slowly put them into the base groove. This can ensure that the tube is not damaged and the installation process can be stable.
In operation, all the lifting machinery should be commanded and operated by specialized personnel. The crane should maintain a stable increase and rotation stability to avoid sudden acceleration or braking.
In addition, all straight steel pipes and pipes used for tap water pipeline projects must meet relevant national standards and design regulations, and have an factory qualification certificate to ensure that it will not pollute the water quality.
