The pipeline laying location of the hydraulic system shall be convenient for branch pipe connection and test, and shall be close to or basic equipment. The following matters shall be paid attention to in pipe laying. The equipment on parallel or vertical pipes shall be deployed to the target, and attention shall be paid to clean and crisscross pipes, although few. The leisure between parallel or cross pipes is higher than 10mm In order to facilitate the line disassembly consultation and installation of pipe clips, and prevent the other side of the transmission line from turbulence, more space should be left between the lines of 10mm.
The pipe does not connect at the arc, and the joint must be flat. The fine pipe along the equipment should be the main body, house and main configuration When installing pipes, shorten the requirements of the pipeline as much as possible and reduce the number of turns, but cut the height in the elbow to ensure the expansion and deformation of the pipe. In a local life consultation, the length of the pipe should be flexible enough to discuss the installation. Every part of the pipe or pipeline should be able to be disassembled and not scattered to other parts. In order to reduce the flow of local resistance loss, reduce the number of corner cutting and bending times in the discussion.
Appropriate pressure holes shall be set at the pipeline location for inspection. The relevant hydraulic system shall be able to measure the stress state of each working address, so that it is common to set pressure points at some medium pipeline addresses. The inlet and outlet pressure shall be checked by reference.
The highest department shall be equipped with an exhaust pipe so that when the ignition off line is in the air. During the installation, maintenance and shutdown of the hydraulic system, gas penetration will occur for a long time Because of the compressibility of a large amount of gas, more of it is deposited in the pressure pipe and suction pipe. The system Z has a great risk of creeping moving parts, causing a series of obstacles such as system charging, turbulence noise and fever. Therefore, exhaust consultation should be set on the high-pressure pipeline to deposit it in the natural gas pipeline.
The tubing sleeve shall be pickled after use The planned system pipes and oil pipes of the oil terminal shall be pickled downward. In order to eliminate rust and impurities, the threads must be coated with acid raw materials for pickling. All pipes shall be installed second When the installation is attempted for the first time, the discussion and flange shall be welded at an appropriate location. When all pipes must be disassembled, acid cleaning or flushing shall be carried out, and drying, oil and pressure tests shall be carried out. The final installation of sand Z shall be prohibited, and the oxidation of iron, scrap iron, lines and components shall be carried out.
To ensure good appearance, the external surface of the welded steel pipe is painted with all ordinary paint. The main pipe is usually red pipe, usually orange control line, the return pipe is ordinary blue or light blue, and the cooling line is yellow.
It should be pointed out that, with the reduction of entrepreneurial skills and production cycle, after the selection of ferrule consultation, pickling and phosphating of the connecting steel pipe connectors of the hydraulic system, there is no need for the above complicated secondary installation. According to the nature of the demand, the steel pipe can be directly run after installation after forming and cutting burrs. "
