Before the official installation of the butt-welded steel elbow, each steel elbow pipe joint must be measured and numbered, and the pipe joint group with the smallest difference in pipe diameter should be selected for docking.
When splicing pipes on the ground, use 14×14cm sleepers under the pipe joints to ensure the stability of the pipe joints. Do not use iron steel pipes, and reduce the rolling of the pipe joints during installation to prevent the anti-corrosion layer of the pipes In addition, it is necessary to check whether the anti-corrosion layer inside and outside the pipe joint is qualified, and the pipe can be lowered only when there is no problem with the anti-corrosion layer. The specific method of lowering the pipe depends on the length of the pipe section, the lifting distance, the pipe diameter, the wall In terms of thickness and so on, make different down tube schemes.
