Hose assembly, hoses need to be stripped and do not need to be stripped two types of rubber. Joints are not the same, need to strip out the type of joint sleeve groove is not too sharp, otherwise it will damage the hose reinforcement layer. It is vital to the safety and normal operation of the hose assembly that the joint is correctly pressed. It can be designed with solid wall or structural wall, and its connection is mainly by solvent bonding.
The main reason is that the production of PVC raw material is less dependent on crude oil than other thermoplastics, making its production cost relatively low. Hose assembly inner diameter should be appropriate, small pipe diameter will increase the flow rate of medium in the pipeline, make the system heating, reduce efficiency, and will produce too much pressure, affect the performance of the whole system. During installation, a formal pipe rack shall be used to fix it. The pipe rack in contact with high-pressure pipes and pipe fittings shall be installed with protective casing according to design requirements. The chamfering of pipe end thread should be exposed during installation.
Hose assembly, installation of gasket, do not use wire hanging, should be in advance on the nozzle and gasket with butter, soft metal high pressure gasket should be accurately placed in the sealing seat. With the implementation of China's offshore oil development strategy, the requirements of offshore oil exploitation on pipeline performance will be continuously increased. If not properly used and maintained, it will seriously affect the quality and life of its use, and even cause the loss of property due to the occurrence of serious accidents. Hose is mainly used for wire, cable, automation instrument signal cable protection tube and civilian shower hose, corrosion resistant ability is very strong, suitable temperature range is wide, the installation of the hose connection, no matter in natural state, or in a state of movement, the bending radius is not less than small bending radius of the hose factory regulations.
The main reason is that the production of PVC raw material is less dependent on crude oil than other thermoplastics, making its production cost relatively low。 Hose assembly inner diameter should be appropriate, small pipe diameter will increase the flow rate of medium in the pipeline, make the system heating, reduce efficiency, and will produce too much pressure, affect the performance of the whole system。 Close pressure relief valve, start software, adjust pressure of hydraulic station, pressure holding time, pressure boost time, high pressure time, pressure relief time, and test times。 Hose assembly as a component of hydraulic system, its performance and life are relatively weak, become the barrier of high pressure selection。
Hose assemblies, the performance and life of existing high pressure hoses, are relatively free of technical challenges. Only the performance and life of the high pressure hose assembly is limited by the manufacturing level of the high pressure hose connection assembly - the hose is always damaged in advance at the connection site. Hose assembly quality directly reflects the quality of hydraulic machinery, hydraulic machinery manufacturers to existing products, has not been very satisfied.
