Rubber joints are also called rubber tube soft joints, flexible rubber joints, rubber soft joints, flexible rubber joints, high pressure rubber joints, compensators, etc. It is a pope joints with high elasticity, high air tightness, medium resistance and weather resistance. In this paper, the author would like to make a brief introduction to the tips on the installation of rubber joints.
In accordance with the connection methods, the rubber joints can be divided into three types, including the loose flange type, fixed flange type and the thread type. However, the rubber joints are mainly include single sphere, double sphere, different diameter body, curved sphere and wind pressure coil according to the structure. This product can reduce the vibration and noise, playing a significant role in thermal expansion and compensation caused by the temperature changes. Moreover, the rubber joints are widely used in various piping systems.
Tips on the installation of rubber joints can be described as following:
1.The rubber joints is strictly prohibited from being installed at the super displacement limit during installation. When the rubber joint is installed flat, suspended or vertically, the actual working axial displacement pressure of the rubber joint is less than the supporting force of the pipeline. Otherwise, the anti-pulling device should be installed to prevent the pressure from being pulled off during work.
2.The pipe must have a fixed support or a fixed bracket, and the force of the fixed bracket must be greater than the axial force. For vertical installation and overhead installation, the corresponding fixed bracket and force bracket should be installed at both ends of the product to prevent the work from being pulled off after being pressed.
3.The mounting bolts should be symmetrically and gradually tightened to prevent partial leakage. Moreover, it should be kept away from the heat source during the installation. It is wise to avoid using the media that does not meet the requirement of this product.
4.When installing a flexible rubber joint in the pipe, it must be kept in a natural status and do not artificially deform the product. Besides, the flange connecting with the rubber joints should be a valve flange or a flange conforming to the GB/T9115.1 (RF).
5.The normal applicable medium for the flexible rubber joint is the ordinary water with a temperature of 0-60 ° C. For special media such as oil, acid and alkali, high temperature and other corrosive and hard texture, the corresponding rubber material joint should be selected. , can not be blindly used or universal.
6.When the rubber joint is transported, handled, or installed, it is forbidden to sharpen the surface sealing surface. The rubber soft joint should be re-pressurized and put into operation after the initial pressure (such as installation pressure test) or long-term deactivation.
7.Every six months, the two samples are taken from the product with a nominal inner diameter of 100 mm or more for testing. One of the test results is unqualified, and two additional samples should be taken from the batch for retesting. If there is still one failure, the batch of the product shall be judged as unqualified.
The above mentioned text is a brief introduction to the tips on the installation of rubber joints. You be careful enough to install the rubber joints, and taken these tips into consideration.
