The unique feature of the clamp type rubber expansion joint.

Clamp type bendable rubber expansion joint uses clamps to replace flanges and bolts, when using, it is convenient to set the two orifices of the clamp type bendable rubber joint on the pipeline to be edge connected, and the rubber joint is fixedly connected to the pipeline through the clamps, when disassembling, the said clamps can be loosened, so as to achieve the purpose of compensating the displacement produced by the pipeline due to thermal expansion and contraction and water transmission.
 
It has the following characteristics compared with the usual rubber expansion joints.
1 . Clamp type rubber joint saves flanges and bolts, which saves the expense of the project.
2 . Clamp type rubber joints have unnecessary flanging at the mouth, which simplifies the production process of rubber joints and saves raw materials.
3 . Clamp type rubber joints simplify the installation and maintenance work and increase the work progress.
4 . The clamps are made of stainless steel, with characteristics such as corrosion resistance, diameter from DN50-400, pressure level from 0.25mpa-1.0mpa. Some details must be noted when the clamp connection, first of all, to measure the quality of the steel pipe, including the length of the outer diameter, the thickness of the pipe wall is uniform, the tolerance of the pipe at both ends of the orifice is not round there is no difference with the national standard, these checks are completed and confirmed qualified before the next step of the operation. Then measure and check the orifice before pressing the groove, that is, watch the end of the orifice and the center line of the tube to maintain vertical; irrigation flow of the tolerance of the incompatibility has not exceeded the standard, if part of the incompatibility of the orifice has exceeded the standard or deformation phenomenon, must be removed from the problem areas; around the orifice there is no burr, if there is to get rid of them, but also grinding and polishing. Then down is the pressure groove processing operation, in the longer steel pipe pressure groove, must be set up to support the bracket, and to install ball bearings in the bracket, and support points, so as to reduce the amount of pressure groove when the pipe rotation fluctuations.
