Waterjet accessories: gasket installation

Sealing gaskets are very commonly used spare parts for equipment. Did you install the factory gasket correctly? If it is installed incorrectly, the gasket will be damaged when the equipment is running, and it may even be dangerous.

1. Inspection and cleaning:

Remove all foreign impurities and debris from the gasket pressing surface, various fasteners (bolts, studs), nuts and gaskets;

Check the fasteners, nuts and gaskets for burrs, cracks and other defects;

Check whether the flange surface is warped or deformed, whether there are radial scratches, whether there are marks of deep tool bumps, or other defects that affect the correct seating of the gasket;

If a defective original is found, it should be replaced in time. If you have any questions about whether to replace it, you can contact the sealing manufacturer in time.

2. Alignment flange:

Align the flange surface with the bolt hole;

For any situation that cannot be positive, a report should be submitted in a timely manner.

3. Install the gasket:

Confirm that the gasket meets the specified size and specified material;

Check the gasket to ensure that there are no defects;

Insert the gasket carefully between the two flanges;

Confirm that the gasket is in the center position between the flanges;

Unless the gasket installation instructions require the use of adhesives or anti-sticking agents, do not use it privately; align the flange surface to ensure that the gasket is not punctured or scratched.

4. Lubricate the stressed surface:

Only the specified or approved lubricants are allowed to be used for the lubrication force area;

Apply enough lubricant on the bearing surfaces of all threads, nuts and washers;

Ensure that the lubricant does not contaminate the flange surface or the surface of the gasket.

5. Install and tighten bolts:

Always use the right tools

Use a calibrated torque wrench or other tightening tools that can control functions;

Consult the technical department of the seal manufacturer regarding torque requirements and regulations;

When tightening the nut, follow the "cross symmetry principle";

Tighten the nut according to the following 5 steps:

The first step: the initial tightening of all nuts is done manually, and the larger nuts can be tightened with the aid of a small manual wrench;

Step 2: Tighten each nut to approximately 30% of the required total torque;

Step 3: Tighten each nut to roughly 60% of the required torque;

Step 4: Use the "cross symmetry principle" again to tighten each nut to reach 100% of the required torque of the whole wood;

Note: Large diameter flanges can use more times to perform the above steps

Step 5: Tighten all the nuts one by one in a clockwise direction at least once to achieve all the required torque.

6. Tighten the bolts again:

Note: Consult the technical department of the seal manufacturer for guidelines and suggestions on re-tightening the bolts;

Non-asbestos gaskets and gaskets containing rubber components that have been used at high temperatures must not be tightened again (except as otherwise specified);

Fasteners that receive corrosion thermal cycles need to be tightened again;

The re-tightening operation should be carried out at ambient temperature and atmospheric pressure.
