- Inner Diameter (ID): The inner diameter of these test hoses is typically from 6mm to 13mm though it may vary depending on the application and pressure requirements.
- Working Pressure: Most pressure test hoses can withstand a pressure of about 20 MPa (Mega Pascals) or 3000 psi (pounds per square inch) though some cases can go to higher values.
- Material: The most common materials applied in pressure test hoses are rubber, polyurethane, and stainless steel braid which are used due to their durability and flexibility.
How to Install
- Preparation: The first step in installing a pressure test hose is to make sure that both the hose and the equipment to which it will be connected are in good shape. The hose ends should be bare and clean while the equipment should be free of debris and wear.
- Connection: Once everything is preparied, the next thing to do is to attach one end of the hose to the pressure source like a pump or a compressed gas cylinder. The other end has to be fixed to the equipment or system being pressure tested. This could be valve, fitting or gauge. Ensure all the connections are tight and secure to avoid leaks.
- Safety Checks: Before applying pressure, do a safety check by examining the hose for cracks, bends and anything that may seem like it is unconnected. Also ensure that the connections are tight so that no one will be at risk of exposed to high pressure fluid leaks.
- Begin Testing: Finally, begin testing by gradually increase the pressure while watching the dial of the gauge. Do not rush the process. Take your time and watch closely for any sign of leaks or hose failure.
How to Use
- System Check: Prior to start using the hose, ensure that it is compatible with the test fluid and the pressure range required. Several industries like automotive, construction, refrigeration and hydraulic have used pressure test hoses to check for leaks and measure pressure.
- Connection: Connect one end of the hose to the pressure source like a pump or compressed gas cylinder and the other end to a system with the pressure to be measured. The hose should be securely locked in place to avoid leaks.
- Testing: Slowly raise the pressure from the source while watching the gauge. This provides a visual representation of the pressure exerted. Do not push the pressure beyond the limit as indicated by the hose. Doing so can lead to hose rupture or hazardous conditions.
- Monitoring: As pressure is increased, observe the hose for any signs of weakness like bulging, cracks, or any other thing that may be disturbing. Also watch the gauge like hawk to see whether the desired pressure has been achieved.
Maintaining
- Proper Storage: Store pressure test hoses in a clean, dry, and shielded from direct sunlight and extreme temperatures. Avoid folding or twisting the hose to prevent inner damage from kinks and bends.
- Regular Inspection: Examination in frequency should focus on the outer and inner part of the hose. Look for signs of wear and tear like cracks, fraying or corrosion. This may probably result in low test accuracy and even mishaps.
- Cleaning: After every use, clean the pressure test hose with a soft damp cloth to remove all the contaminants. Certain Chemicals and debris can breakdown the material of the hose.
- Pressure Release: Always remember to release the pressure completely from the hose once tests are over. This will avoid stress on the material that causes the hose to rupture or wear out old.
- Professional Maintenance: If the hose has suffered extreme damage or appears worn out, professional services should be called to maintain it. Using damaged hoses is dangerous and can cause test failures or accidents.
