In our life to meet variety of pipes, pipelines have different categories, used in different industries, including the familiar faucet, floor heating pipes, ventilation pipes, pipeline in many industrial pipes, such as municipal district heating pipes, heating pipes), provide water for residents of the potable water supply, drainage, drainage pipe, Natural gas pipeline, and many petrochemical industry pressure pipelines. The classification of these pipelines is not the same, and the method of use is not the same. Today we will talk about the installation of pipeline engineering and common matters needing attention in pipeline construction.

First, what is the pipeline installation?

Pipework installation refers to the engineering project of piping used to transport liquid, petroleum, natural gas, or solid slurry. Pipeline engineering installation includes the supply of pipeline materials, pipeline laying, and installation.

1, high professional: because the pipeline engineer's contemporary technical standards are very high project. It has its own facilities are all under high working pressure and safety to do a good job of conveying.

2, comprehensive strong: some are the usual construction engineering, and technical professional construction engineering and construction technology. The overall scale of the project is very large, is a comprehensive industrial project construction.

3, the complexity is very high: the pipeline through the area is all high mountains and rivers. Some of them go through swamps. Even in desert areas. Therefore, according to the terrain of pipeline construction, the complexity of pipeline engineering installation is very high.

Two, pipeline construction should pay attention to what

1, the heating pipeline should be set up in inclination. The inclination of the steam pipe where the soda is flowing in the same direction is usually 0.003, and the inclination shall not be less than 0.005 when the soda is flowing in the opposite direction. The hot water pipe shall have an inclination and slope discharge device not less than 0.002.

2. Steam branch pipe should be connected from the top or side of the main pipe, and the hot water pipe should be connected from the bottom or side of the main pipe. The drain pipe with different working pressure can not be connected to the same pipe.

3, horizontal pipe diameter should be connected by the eccentric reducer. When the conveying medium is steam, the bottom of the pipe is flat to facilitate drainage; When the conveying medium is hot water, the top of the pipe should be flat to facilitate the exhaust.

4. The steam pipe is usually laid on the right side of its forward direction, and the condensate pipe is on the left. The hot water line is on the right and the return line is on the left.

5, pipe through the wall or concrete floor should be installed with a waterproof casing.

6. When the directly buried pipeline crosses the railway line and highway, the Angle of intersection is not less than 45°, the top of the pipe is not less than 1.2m from the rail surface, and is not less than 0.7m from the road surface. A waterproof casing should be added, and the waterproof casing should be not less than 1m from the railway subgrade engineering and the road edge.

7, the pressure regulating valve should be vertically installed in the horizontal pipeline after the installation and should be adjusted according to the application of working pressure. The pressure-reducing valve set is usually built 1.2m away from the road. If it is built 3m away from the road, a permanent actual operating platform should be installed.

7. After the completion of pipeline construction, hydrostatic tests and cleaning shall be done according to the design scheme or standard specifications.

Pipeline engineering installation, therefore, is a large category, is not common to our everyday life, and pipeline construction has certain common points for attention, both their practical operation and professional practice, must be one by one to master, follow the steps done, pay special attention to water pressure test, acceptance of work even later still have to pay special attention to maintenance, Extend its service life.
