The installation of oil-resistant hoses for petroleum pipelines
The installation of oil-resistant hoses for petroleum pipelines is a process involving multiple key steps and precautions. The following are specific installation methods:
1. Preparation before installation
Choose the right hose: According to the working pressure, connection method, medium (such as oil) and compensation requirements of the oil pipeline, choose the right oil-resistant hose model and specification. Make sure that the hose can withstand the working pressure and temperature changes in the pipeline and has good oil resistance.
Check the hose and connector: Before installation, carefully check the quality of the hose and connector to ensure that they are not damaged, cracked or worn. At the same time, confirm that the model of the connector matches the hose.
2. Installation steps
Cleaning the pipe and connector: Before installing the hose, make sure that the inner wall of the pipe and connector is clean and smooth, without defects such as adhesion, defects, sand, rust, oxide scale, etc. This helps to ensure good sealing performance and extend the service life of the hose.
Connecting the hose and connector: When inserting the hose into the connector body, use moderate force to avoid damaging the internal structure of the hose.
Use the correct connectors and tools, such as torque wrenches, to ensure that the connection between the hose and the connector is firm and reliable. When tightening the nut, after the torque begins to increase suddenly, tighten the nut by 1/6 turn to achieve the requirement of sealed connection.
Install metal reducer (if applicable): When using NBR oil-resistant rubber pipe joints, especially at the inlet and outlet of the water pump, the metal reducer should be installed on the side close to the water pump and installed at the large diameter of the reducer to enhance the stability and sealing performance of the connection.
Adjust pipeline displacement: If the pipeline displacement is large, the number of joints needs to be increased to achieve parallel displacement. Avoid adjusting the pipeline at will or excessively bending the hose to ensure the normal use of the hose and extend its service life.
Fix the hose: During installation, the hose should be fixed in place with a suitable fixing bracket or clamp. This helps prevent the hose from moving or vibrating during use, thereby ensuring the stability and safety of the connection.
III. Inspection and maintenance after installation
Check the sealing performance: After installation, check the connection between the hose and the joint to ensure good sealing performance. If leakage or poor sealing is found, it should be handled in time.
Regular maintenance: Regularly inspect and maintain the hose and joint, including cleaning, tightening the connector, and checking the wear of the hose. This helps to detect and solve problems in a timely manner and ensure the normal operation of the pipeline system.
In summary, the installation of oil-resistant hoses for petroleum pipelines requires comprehensive consideration of multiple factors and strict installation steps and precautions. Through proper installation and maintenance, the reliability and safety of the hoses in the petroleum pipeline system can be ensured.
