Comparison between Beijing Grip pipe coupling and flange

The traditional pipeline connection repair method mainly uses welding, flange and other methods, so there are very big hidden dangers in many aspects of operation, such as coal mine, natural gas pipeline, oil transmission pipeline, etc., and the traditional pipeline connection repair method needs a large working space, if necessary, large construction vehicles should be used to enter the operation site. There are several advantages of using quick pipe coupling repair device.

I. General / compatibility:

1. It is suitable for connecting pipes of the same or different material, thin wall or thick wall, and is compatible with other traditional connection methods.

2. The allowable diameter difference of two pipe connections with different diameters is 4mm.

3. When there is a certain dislocation between the pipes and the axis has a deflection angle, the pipes can be used normally to avoid the problem of pipe correction.

4. It can also be effectively used in places with external shock, vibration, extrusion, thermal expansion and contraction, and can play a better role in noise reduction and expansion joint.

II. Simple operation and time saving:

1. The installation time is 3-5 times faster than that of welding, flange and thread, which greatly shortens the construction period.

2. No need for professional personnel, one hour of training can be used to reduce labor costs.

3. There are many types and specifications of products, which can meet the needs of field engineering in most occasions.

4. No special installation tools are required. It can be disassembled and reused without maintenance.

5. The joint of the connecting patching device can be rotated to select the best position for screwing bolts, and can be installed even in a narrow place.

III. Cost saving and high cost efficiency ratio:

1. The installation cost is easy to predict, the calculation is more accurate, and the manual installation cost is saved by 20-40%.

2. There is no need for expensive treatment of pipe ends, no need for a large number of skilled welders, welding cables and other personnel and equipment, and the installation is simple.

3. It is light in weight, simple and fast in installation, no need to assemble itself, and no need to adjust and process the connected pipeline. During installation, only the torque wrench is required to tighten 2-3 bolts from one side according to the specified torque, which is particularly convenient for operation.

4. From the perspective of the whole project, the cost is lower than that of welding.

IV. It is simple to change the line and convenient to assemble and disassemble:

1. It is easy to maintain, and it can clean, repair and change the pipes quickly, with excellent economy.

2. Save installation space, suitable for complex space pipeline.

3. Avoid the quality problems in welding and the work problems caused in the use process.

4. There is no welding slag in the pipe and no need to clean, which avoids the problem of pipe blockage in the use process and affects the normal life of residents.

V. Earthquake resistance, impact resistance and noise reduction:

1. The traditional rigid connection is changed to flexible connection, which makes the pipe system in the state of anti shock vibration and noise elimination.

2. The flexible pipe connection mode allows the maximum axial deviation angle of the two pipes to be 10 °.

3. Absorb temporary expansion force caused by thermal expansion and contraction or earthquake in long-distance pipeline.

4. It can withstand the acceleration impact of 350g in 0.02 seconds, and the noise intensity can be reduced by 60%, which is conducive to the safe and normal use of the whole pipeline system, including pumps, valves, instruments, etc., and prolong the service life.

VI. Good safety, reliable quality, strong sealing performance:

1. Due to the use of stainless steel shell and special material of rubber ring, it can effectively prevent external drip corrosion and internal medium corrosion.

2. Due to the special structure adopted at both ends of the rubber seal cylinder inside the connector, the long service life of the connector is guaranteed. Among them, the multi-stage lip shaped convex ring plays a multi-stage sealing role in preventing the fluid in the pipeline from leaking out.

3. Generally, it can withstand voltage of 16KG / C ㎡, some of which can reach dozens of pressures, so long-term use will not produce “three leakage” phenomenon.

4. Good safety, no fire hazard, no need of hot work in the whole process of installation and construction.

5. There are quality problems caused by the uneven quality of welders and the imperfect process of welders in non welding system.

6. Quality can be guaranteed and controlled by any installation company.
