Gongyi City Wanquan Pipeline Equipment Factory--Gongyi City Top Ten Integrity Enterprises Generally, in the installation of dust pipes and sand systems, a large number of wear-resistant rubber joints must be used, because the general rubber joints cannot meet the engineering installation standards. The wear-resistant flexible rubber joint is a professional flexible rubber joint dedicated to the desulfurization system. It has good wear resistance, and it can well function in the axial expansion, radial expansion, and angular displacement of the desulfurization pipeline of the compensator. . Gongyi Wanquan Rubber Joints Detailed Explanation
1. When flexible rubber joints are used in pipeline construction, they must be left in their natural state. Do not artificially deform the product during installation. When the pipeline medium is resistant to acid, alkali, oil, high temperature and other special materials, it should use a joint that is higher than the working pressure of the pipeline.
2. The flange to which the flexible rubber joint is connected should be a valve flange or a flange complying with GB/T9115.1(RF).
3, can be wound around the flexible rubber joints normal media is the temperature of 0-60 °C ordinary water, special media such as: oil, acid and alkali, high temperature and other corrosive and hard texture, should be used in response Special resistance materials can be flexible rubber joints, not blindly string or common.
4. Flexible rubber joints should be used on the side of the water spring when the water pump is used for import and export. Metal reducers should be installed between the spring and the water spring, and they should be installed in the large-diameter outlet where the diameter can be changed.
5. When the pipe displacement is greater than or equal to the maximum compensation amount of the joint, the number of joints should be increased to parallel displacement. It is forbidden to adjust the pipe's overshoot to make the joints at the limit of flexural displacement and deviation, and it is impossible to exceed the limit ( Telescopic, Displacement, Deflection, etc.) Use the specific installation data in the table below.
6. For high-rise water supply or suspended water supply, the pipeline shall be fixed on the hanger, bracket or anchor bracket, and the joint shall not be allowed to bear the weight and axial force of the pipeline. Otherwise, the joint shall be equipped with anti-pull device (the bearing capacity must be greater than the pipeline Axial force).
7. When flexible rubber joints are installed, the bolts of the bolts shall extend toward the outside of the joints. The bolts on the end face of each flange shall be repeatedly tightened evenly by means of diagonal compression to prevent the pressure deviation. Spiral joints should be tightened with standard wrenches. Do not use forceps to force the joints to slip, slippery or break, and check regularly to avoid loosening or seepage.
8. Flexible rubber joints should be re-pressurized and tightened before being put into operation after the initial pressure (eg, installation pressure test, etc.) or after long-term deactivation.
9, use or store flexible rubber joints, should avoid high temperature, ozone oil and acid-base environment. Sunshade frames shall be set up for the outdoor or sun-facing winds, and violent storms, rain, and windiness shall be strictly prohibited. It is strictly forbidden to paint and wind insulation on the joint surface. Due to aging problems in rubber products, they should be promptly checked and replaced.
