Before the official installation of the butt welding 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 the butt joint.
When splicing pipes on the ground, use 14×14cm sleepers under the pipe joints to ensure 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, when lowering the pipe, you must first check whether the anti-corrosion layer inside and outside the pipe joint is qualified, and ensure that there is no problem with the anti-corrosion layer before you can lower the pipe. The specific method of lowering the pipe depends on the length of the pipe section, the lifting distance, and In terms of pipe diameter, wall thickness, etc., different pipe lowering schemes are made.
