Introduction: When the inner hole of rubber joint is reinforced with steel ring: when the inner hole of rubber joint is reinforced with steel ring, the steel ring shall be kept in the ring and shall be located in the same plan of the same year. Products shall be identified in the following order: product code and type code

When Rubber joint When the inner hole is reinforced with steel ring: when the inner hole of rubber joint is reinforced with steel ring, the steel ring shall be kept in the ring and shall be located in the same plan of the same year. Products shall be identified in the following order: product code, type code, structure code, performance code, working pressure and nominal diameter. Product and construction codes are specified as follows: Flexible rubber joint RFJ, single sphere D, double sphere s, elbow W, same boat reducing YT, eccentric reducing YP, fan coil joint F. Mark example: rfjd-1.6 × 200,. It refers to the single ball flexible rubber joint with nominal diameter of 200 mm, with working pressure of 1.6 MPa. Working pressure: the experimental pressure of rubber joint is 5 times of the working pressure, and the bursting pressure is 3 times of the working pressure. Vacuum resistance: for rubber joints with nominal inner diameter less than 300 mm and working pressure above 1.6 MPa, the vacuum resistance shall not be less than 100 kPa, and the vacuum degree of other specifications of rubber joints shall be stipulated by agreement between the supplier and the demander.
There are three kinds of connection methods of rubber joint, including screw connection, flange connection, clamp connection and so on. Help to deal with pipe cracking and damage of pipe connection equipment due to thermal expansion and cold contraction. The rubber joint should be installed on both sides of the pipe fitting, and then the rubber joint should be fixed on both sides of the pipe fitting, and then the rubber joint should be fixed on the surface of the rubber pipe The parts are fixed on objects that are not easy to stretch or twist.
If you don't care about the hard work of others, don't worry about the hard work. If you don't care about the hard work, don't worry about it It's not easy to have a lot of fate in this world.
Rubber joint is generally composed of inner rubber layer, fabric reinforcement layer (reinforcement layer has multi-layer scraping nylon cord fabric), middle rubber layer, outer rubber layer, famous reinforced metal ring or steel ring, which is vulcanized at high temperature and high pressure, and is loose with metal flange or parallel joint. This product uses the advantages of rubber, such as high elasticity, high gas resistance, medium resistance, weather resistance and radiation resistance, which can reduce the vibration and noise of the pipeline, and compensate the thermal expansion and cold contraction caused by temperature change.
According to the different media, the rubber materials selected are also different, including natural rubber, styrene butadiene rubber, butyl rubber, butyl rubber, ethylene propylene diene monomer, chloroprene rubber, silicone rubber, fluororubber, etc. They have heat resistance, acid resistance, alkali resistance, corrosion resistance, wear resistance, oil resistance and other functions.
If it is right, don't care about other people's comments, it's only up and down your discrimination; if you need to pay hard, then don't be stingy, your diligence, never a real success, can grow effortlessly in the weeds; if the pay and harvest are not equal, there is no need to complain too much, which will make your heart more tired; if facing full failure, also There is no need to take fate seriously. It is not easy for us to go through the afterlife.
