ROHN Hydraulics tells you what are the requirements for the installation of hydraulic system steel pipes?
May 20, 2021
The hydraulic system is composed of various hydraulic components. The hydraulic components are organically connected by pipes, joints and integrated valve blocks to form a complete hydraulic system. Therefore, whether the hydraulic pipeline is installed correctly, firmly and neatly will have an important impact on the performance of the hydraulic system.
1. Check the quality of the tube. It is necessary to find out whether the material, size and quality of the pipe meet the design requirements; check whether the appearance of the pipe is severely flattened or bent; check whether there is corrosion on the inner and outer wall surfaces of the pipe, and whether there are defects such as cracks on the outer wall. If there is a tube that does not meet the requirements of the regulations or has a serious defect, it cannot be used.
2. Measure the piping size. The position of hydraulic pump station, hydraulic valve table, main engine, auxiliary engine and related parts should be carefully measured and strive for perfection. For pipes with many bending parts and complex shapes between two joints, a sample should be made first, and then the pipe should be cut according to the size or template.
3. The installation pipeline must be reasonably arranged according to the design drawings or the actual location.
4. Air blow the pipes that have been pickled during installation.
5. The joints of the pipes must be connected firmly, and the joint surfaces must be tightly sealed, and there must be no leakage.
6. The pressure oil pipe installation must be firm, safe and stable. The quality of the seals should be carefully checked during installation. Seals that do not meet the requirements are not allowed to be used. When installing the seal, pay attention to the lip direction, and install it carefully. Do not scratch or damage the seal, let alone miss the installation.
7. The welds of butt-welded pipes must undergo a pressure test.
