Product Details

high temperature resistant screw rubber expansion joint

Product Description

Thread-Connection rubber joint in the need to connect the ends of the pipe before installation in the horizontal plane flat, when installation the thread is rubber joint twist in one of the first period of pipe fittings, then at the end of a screw pipe fittings, always stay in the horizontal plane, to prevent the uneven in the process of installation and torn rubber ball, and then the thread by hand or wrench tight, finally put the thread on both ends of the rubber joint and pipe fixed on it is not easy to stretch or distorted objects.

Product performance:
1, Thread-Connection rubber joint has good elasticity and long service life, especially for some installation environment is harsh environment have a good ability to adapt.
2, installed on the pipeline can be achieved for pipeline axial, lateral and angular displacement compensation, guarantee the pipeline safe operation, so as to prolong the service life of pipelines.
3, good vibration reduction noise reduction function, greatly optimize the running environment of the pipe lines.

Product use:

Due to Thread-Connection rubber joint has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, water drainage, oil, light and heavy industry, freezing, sanitary, plumbing, fire protection, electric power and other basic engineering, shakes the pipes of larger pipe, cold heat changes frequently.

Installation instructions:
1, when installation to protect the ball at the ends of the rubber sealing surface, and the media do not meet the requirements of the product is strictly prohibited. Please refer to additional product installation manual carefully before install and use, to avoid some unnecessary loss.
2, eccentric reducer rated working pressure of the rubber joint working pressure than it actually is a gear, to ensure the safe operation of the pipeline can.
3, pipe must have a fixed support or fixed bracket, the force must be greater than the axial force of fixed bracket. When installed vertically and aerial product should be installed on both ends of the corresponding fixed bracket and mechanical support, in order to prevent pulled off after work under pressure.
4, rubber joint in the process of flange connection, according to diagonal uniform pressure way for installation, it can avoid uneven force, cause the late of pipeline leakage.
5, rubber joint during the installation process must avoid beyond their displacement to compensate the pipeline vibration and heat bilges cold shrink. By adding spacing device or increase the quantity of rubber joint, divide the work pressure is the right choice.
