Product Description

Product Application

At present, coal, electricity, construction, chemical industry, fire control, sewage treatment, metallurgy, tap water, pharmaceutical, municipal, petroleum and other fields have been widely used. Transport medium includes hot and cold water, smoke, wind, oil, chemical raw materials, acid and alkali medium, food fluid, sea water and other fluids.

Main Features

1. Reasonable structure and high strength
The working state of the clamp is equivalent to the pressure vessel, the axial force of the medium is completely borne by the clamp, and the bolt only bears the radial force of the clamp. Because of the limited width of the sealing ring, the radial force is much less than the axial force. When the flange is connected, the bolt bears all the axial force and the pressure of the washer.
2. Good self-sealing effect
The sealing effect depends on the pressure of the medium in the pipeline to the gasket. The greater the pressure, the better the sealing performance. In order to prevent the leakage of medium in the absence of pressure, the inner diameter of the gasket is smaller than the outer diameter of the pipe end interface. Compared with the flange, the larger the pipe diameter, the higher the pressure, the more prominent advantages.
3. The pipe connection is in a flexible state
There is a gap between the clamp and the end of the pipe. Therefore, the adjacent two end pipes are allowed to have a certain Angle. After the steel pipe is connected, there is a gap between the ends of the two steel pipes, which allows the pipe to move in axial direction and can adapt to expansion and contraction of the pipe. The rubber ring connection between tubes can effectively reduce mechanical vibration by more than 70%.

Installation method of clamp-type flexible expansion joint/clamp-type expansion joint:
When the pipe needs to be turned over, just remove several bolts of the joint to reverse any Angle without cutting and welding, which saves a lot of auxiliary workload and cost, reduces labor intensity and shortens the construction period. Compared with the flange connection, the working efficiency is improved 6-8 times, and the maintenance work is very small. Through improvement, we can derive the flexible telescopic joint without disassembly and direct welding. It is more convenient to install. Only the bolts need to be removed during maintenance.
