Product Characteristics

KDF-F flanged rubber joint is an improved version of KXT single sphere rubber joint according to user's demand, which can relatively withstand greater displacement and pressure. What's more, it improves the pull-off condition of single sphere rubber joint under too high pressure. The sealing surface of the improved big flanging rubber joint is the same as the outer diameter of flat welding flange, and there are drilling holes on the sealing surface, which completely connects the rubber joint with the pipeline as a whole, so as to improve the stability of the operation of the pipeline.

It is a kind of pipe joint with high elasticity, high air tightness, medium resistance and weather resistance. It has high internal densification, can withstand high pressure, and has good elastic deformation effect.

Rubber joint is composed of fabric reinforced rubber parts and loose metal flanges, which is used for pipeline vibration and noise reduction, compensation displacement joint. Gongyi Xinli strictly in accordance with the standards and quality requirements of raw materials, to put an end to the phenomenon of jerry-built, ~ standard that the raw materials of the product not only need new materials, but also need ~ level new materials. Rubber joints are also known as flexible rubber joints, pipe dampers, shock absorbers, soft joints and so on.

Because of the good comprehensive performance of the flexible rubber joint, it is mainly used for the lifting and transportation of raw water and sewage, the feed water and cooling circulating water of thermal power plants, metallurgical industry, condensate, chemical industry, chemical substance pipeline transportation, petrochemical industry, cooling, dilution, and other industries of long and short distances of the flexible connection between the pipeline. Because of the high abrasion resistance of rubber, it is also suitable for the transportation of granular and powder and vapor in the industry.

KDF-F flap type rubber joint product installation instructions:

1, rubber joints in the pipeline construction, you need to let it in a natural state, prohibit the installation of super-displacement.

2、When the medium of pipeline is acid and alkali resistance, oil, high temperature and other special materials should be used higher than the actual working pressure of the pipeline a grade of the joint.

3、When installing rubber joints on flat ground, overhead and vertically, the actual working axial pressure of rubber joints is less than the supporting force of the pipeline, otherwise anti-drawing off device should be installed to prevent unstable operation of the pipeline when working.

5、Vertical installation and overhead installation of the product needs to be installed at both ends of the corresponding fixed bracket and the force bracket, in order to prevent the work under pressure after pulling off.

6, the installation should be away from the heat source, is strictly prohibited to use the product does not meet the requirements of the medium.

7, when the pipe displacement is greater than or equal to the joints of a large amount of compensation, the number of joints should be increased to parallel displacement, it is strictly prohibited in order to adjust the pipeline overshoot, so that the joints are in the state of deflection displacement and deviation, and even more can not be over the limit (expansion, displacement, deflection, etc.), the use of the specific installation data see the following table.

8, high-level water supply or suspended water supply, the pipe should be fixed in the hanger, bracket, and can not let the joint to bear the pipe's own weight and axial force, otherwise the joint should be equipped with anti-pull-off device.

9、When installing the rubber joint, the screw of the bolt should be extended to the outside of the joint, and the bolts of each flange end face should be tightened repeatedly and evenly according to the method of diagonal pressure, so as to prevent pressure bias.

Product Case

Flanged single sphere restriction rubber joints used in the industrial belt project in Jundong

Flanged single sphere restriction rubber joints used in the construction of industrial belt projects in Jundong play an important role in the development of industrial belt in Jundong provides an excellent supporting role. The person in charge of the Xinjiang Changji State Coal Chemistry Office, the industrial belt functional layout supporting the water supply and drainage, transportation and logistics, power grid framework, land use, greening and other five special sub-planning has been approved, coal power coal chemical industry belt in 2010 to complete a phase of the project, of which the infrastructure of the first phase of the basic completion in 2009, a cumulative total of 3.5 billion yuan in investment. The 138-kilometer-long Jundong Highway has been completed and opened to traffic, and the ring-shaped transportation channel of the industrial zone has been formed. The railroad from Urumqi North Station to Jundong has also been put into operation, with an annual freight capacity of 15 million tons.

It is understood that this year is the Xinjiang Changji state quandong industrial belt project construction year, plans to start 12 projects. Among them, 4 coal mining projects, striving for coal production exceeding 30 million tons; 3 coal power projects, the construction of two 600,000 kilowatts of thermal power plant, a 1.2 million kilowatts of thermal power plant; 5 coal chemical projects, to complete the construction of a 1.3 billion cubic meters of coal to natural gas projects, 3 4 billion cubic meters of coal to natural gas projects, 300,000 tons of coal tar to diesel oil engineering projects. We believe that in the near future, the figure of Dongli flanged single sphere limit rubber joints will appear in more pipeline projects, providing pipeline compensation for more projects. Welcome to buy.
