Introduction: The expansion device is made of special synthetic rubber material, which is resistant to high temperature, acid, oil and chemical corrosion. It is an ideal conduit. It is also called flexible pipe joint. The retractor rubber has excellent performance

Telescopic device Made of special synthetic rubber material, the device can resist high temperature, acid, oil and chemical corrosion. It is an ideal conduit. Also known as Shock absorber Rubber tube expansion joint, Pipe shock absorber Shock absorber throat, soft joint, flexible metal pipe joint. Retractor rubber has excellent weather resistance and ozone resistance. According to reports, after years of natural storage performance is still satisfactory, 45 days after the air is not significantly affected by the cracking of 0.01 ozone concentration. Retractor rubber weather resistance, ozone resistance is also excellent. In the vacuum expansion joint, the rubber has excellent performance Expansion joint And rubber have excellent mechanical properties. The thermal expansion joint makes the coating can be used in various harsh environments and different media, which not only increases the mass transfer joint, but also greatly prolongs the life of the power transmission joint, making the thermal seal coating technology has been widely used.
The expansion device is mainly used to ensure the operation of the pipeline, which has the following functions: compensating the axial, transverse and angular thermal deformation of the absorption pipeline; absorbing the vibration of the equipment to reduce the impact of the equipment vibration on the pipeline; absorbing the deformation of the pipeline caused by earthquake and ground subsidence. In a certain range of axial expansion and contraction, it can also overcome the offset caused by different axes of pipe butt joint in a certain angle, which can greatly facilitate the installation and disassembly of valve pipeline, and can freely expand and expand in the allowable expansion amount of pipeline. Once the large expansion amount is exceeded, the limit will be reached to ensure the operation of the pipeline. Therefore, the shell test pressure of the expansion joint of our company is 1.5 times of the nominal pressure, and there is no leakage, structural damage and obvious plastic deformation. The sealing test pressure is 1.25 times of the nominal pressure, and there is no leakage under constant pressure for 5 minutes.
It can be used to compensate the main elastic bellows such as pipe, pipe or size change. The retractor can be mainly used in the mechanical displacement of the pipeline system, displacement heating absorption vibration, reduce noise, so as to absorb displacement in all directions. The bolts of the front mounting plate need to be loosened, the installation length should be pulled, and then the diagonal method should be tightened instead of partial pressure. For example, if it is used overhead, it should be installed at both ends of the corresponding mounting bracket. It is forbidden to use deformation to adjust the installation expansion joint of the pipeline, which will affect the normal life of the expansion joint and increase the burden of the pipeline.
All other components of our conduit are gland type limit expansion joints, baffles, fittings, seals and other components of flange sleeves. In the manufacturing process, the raw materials can be selected according to the user's requirements, and a variety of different raw materials can be used for the conduit. Connectors and other components can be stainless steel or alloy materials. The user environment is different, manufacturing joint force information and using the latter, the available function of the power transmission connector to stabilize and increasingly become the target of the latter half. After being installed in the pipe, the elastic seal ring tightens the nut, tilts under the action of the interdependent compression nut, and pushes the seal in the pipe and connecting outer ring. When the temperature changes in the pipe joint, it can stretch freely between the local water tanks, twist the pipe and ensure no leakage sealing, so as to make the playback automatic compensation purpose.
