When replacing the Pu Steel Wire Hose, to ensure safe operation, pay attention to the following matters:
1. System pressure relief
Before operation, the power supply of the equipment must be turned off to completely release the pressure in the pipeline to avoid the splashing of the medium when the Pu Steel Wire Hose is disassembled.
2. Personal protection
Wear protective gloves and goggles to prevent contact with residual media or scratches from metal burrs at the pipe mouth.
3. Correct disassembly
Use special tools to loosen the joint and avoid violent pulling. Pay attention to the connection method of the old hose and record the installation direction.
4. Cleaning inspection
Remove the residue at the joint and check whether the interface thread is intact. Confirm that there is no transportation damage before installing the new hose.
5. Standard installation
Ensure that the new hose matches the specifications of the joint and connects correctly according to the medium flow direction mark. The joint must be tightened evenly to avoid unilateral force.
6. Test operation
First perform a low-pressure test to check whether each connection is leaking, and then gradually increase to the working pressure after confirming that it is normal.
After the operation is completed, fill in the replacement record, including date, specifications and other information. Note that the bending radius of the Pu Steel Wire Hose should be greater than the specified minimum value to avoid sharp bends that affect its service life.
