Installation Instructions

Ceramic-Rubber Hose Installation Instructions

1. Pre-Installation Preparation

1.1 Material Inspection

1. Before installation, inspect the appearance of the ceramic-rubber hose to confirm that there are no cracks in the ceramic lining, no damage to the rubber layer, and no looseness in the flange connections. Any non-conforming products must be replaced immediately.

2. Verify that the model, specification, length and connection type (flange, quick coupling, etc.) of the hose fully match the design requirements and on-site installation conditions.

3. Prepare matching auxiliary materials and tools: gaskets compatible with the conveyed medium and temperature, bolts and nuts, wrenches, torque wrenches, level gauges; if hoisting is required, prepare lifting equipment such as cranes and winches in advance.

1.2 On-Site Environment Inspection

1. Ensure the installation site is clean and free of debris, obstacles and other factors that may affect construction.

2. Confirm that the ambient temperature on site is within the applicable range of the hose (the standard operating temperature range is -20℃ to 80℃; refer to the product manual for special working conditions). Avoid installation operations in extreme temperature environments.

2. Installation Procedures

2.1 Lifting and Handling

1. During handling, never drag or throw the hose. Avoid scratching the rubber layer or bumping the ceramic lining with sharp objects.

2. If hoisting is required, use slings with a width of not less than 50mm. The lifting points shall be evenly distributed on the flange parts at both ends of the hose. Never directly lift the hose body to prevent deformation and damage.

2.2 Flange Connection

1. Clean the sealing surfaces of the hose flange and the mating equipment flange to remove oil, rust, impurities and other contaminants, ensuring the sealing surfaces are flat and undamaged.

2. Place the gasket steadily in the center of the flange sealing surface. Never allow gasket misalignment or stacking.

3. Align the bolt holes of the hose flange with those of the mating flange. When inserting bolts, keep them vertical and do not strike the bolts forcibly.

4. Tighten the nuts using the diagonal cross tightening method, applying force gradually in 2-3 stages. Finally, use a torque wrench to tighten to the torque value specified in the product manual (refer to the product technical manual for standard flange bolt torque values). Ensure uniform force distribution on all bolts to eliminate leakage risks.

2.3 Hose Positioning

1. After installation, the hose shall be naturally straight without excessive bending, twisting or stretching. The bending radius of the hose shall not be less than the minimum value specified by the product.

2. When the hose is used for connecting vibrating equipment, reserve appropriate expansion allowance to prevent vibration-induced pulling of the hose during equipment operation.

3. When securing the hose, use dedicated pipe clamps. Install rubber pads between the clamps and the hose. Never directly clamp the hose body with metal pipe clamps.

3. Post-Installation Inspection and Commissioning

3.1 Installation Quality Inspection

1. Check the tightness of the bolts at the flange connection points to confirm there is no looseness; inspect the gaskets for extrusion or deformation.

2. Verify that the installation position and angle of the hose comply with design requirements, with no twisting or stress concentration.

3.2 Commissioning

1. Before commissioning, bleed air from the pipeline, slowly increase the pressure to 50% of the working pressure, hold the pressure for 30 minutes, and check for leaks.

2. If no abnormalities are found, gradually increase the pressure to the rated working pressure, hold the pressure for 1 hour, and inspect all connection points and the hose body again to confirm there is no leakage or abnormal deformation.

3. During commissioning, observe the operation of the hose under medium conveying conditions to ensure there is no abnormal vibration or noise.

4. Precautions and Maintenance

1. Never adjust the alignment of flange bolt holes by twisting the hose after installation is completed.

2. The service medium, pressure and temperature of the hose shall not exceed the limits specified in the product technical parameters. Avoid overloading the hose, which may cause ceramic lining detachment or rubber layer aging and damage.

3. Regularly inspect the tightness of hose connections and the appearance of the rubber layer. If leaks, damage or other issues are found, shut down the system immediately for maintenance.

4. For hoses that are out of service for an extended period, drain the internal medium and store them in a dry, well-ventilated indoor environment, protected from direct sunlight and rain.
