As a new type of pipe joint technology, grooved pipe joints have obvious advantages of convenient construction and reliable quality. First, the connection of the pipe fittings 1. Clamp installation (1) Install the sealing ring: Put the sealing ring into one end of the pipe mouth, then align the other pipe mouth with the end pipe mouth, and move the sealing ring to the sealing surface of the two pipe ports. The sides of the seal should not protrude into the grooves of the two pipes. (2) Install the joint: first loosen the two screws of the joint, divide it into two pieces, put two pieces of shell on the sealing ring, insert the bolts, and tighten the nut in turn to ensure that the two ends of the shell enter the groove until it is tightened. 2, mechanical three-way, mechanical four-way installation First remove the bolt from the outer casing, loosen the other nut until the end of the bolt, the lower shell is rotated about 90 degrees from the upper shell, the upper shell outlet part is placed in the tube The mouth opening is centered and aligned with the hole, and then the lower shell is rotated along the tube end (for example, the mechanical cross, the lower shell method is the same as the upper shell) to close the upper and lower parts. 3. Flange plate installation Install the flange piece: first loosen the screws on both sides, separate the two flanges, insert the ring-shaped key parts of the two flange pieces into the groove of the grooved pipe end, and then put the two sides Screw the screws tightly and adjust the clearance on both sides to be close. Install the sealing ring: push the “Cshaped opening of the sealing ring away from the flange and push it into the inner diameter groove of the flange along the tube end. Second, the bracket setting 1, the fixed bracket and the guide bracket The hanger and bracket can control the degree of freedom of the pipeline, the spring hanger can make the pipeline fully free. Flexible joints allow for deflection in the pipe. This feature has great advantages in installation and engineering piping, but careful consideration should be given to the spacing of the brackets and hangers in the piping. The design and installation of the end supports must be carefully considered for the cumulative elongation of the pipe when the internal pressure increases or the temperature rises. Fixed fulcrums can be used to prevent pipe displacement caused by internal pressure and expansion. There are two types of fixed fulcrums: the main fixed fulcrum and the intermediate fixed fulcrum. 2. Influence of long pipelines For long-pipe systems, intermediate fixed points are used to disperse the forces generated by the thermal expansion of the pipeline and the internal pressure of the pipeline. The weight of the piping and equipment in the piping system needs to be supported by the brackets. In addition, some brackets should allow the ducts to expand and contract. 3. Influence of thermal expansion and contraction The displacement caused by thermal changes in the piping system can be partially compensated by the piping method. The flexible joint can effectively compensate the displacement of the pipeline caused by thermal expansion and contraction. If the predicted displacement exceeds the total joint compensation in the system, a metal expansion joint must be installed at the relevant location of the system. Third, the actual installation of the support and hanger in the Changli Road system Long riser system mainly has the following forms: (1)

Clamp-type flexible pipe joints are fast, simple and economical pipe connection technology. From the perspective of the medium to be transported, it can be applied to transport water, natural gas, petroleum, coal ash, chemical liquids, etc., to fully compensate and overcome the defects and deficiencies in the pipeline flange connection, in coal, electricity, natural gas, water supply, fire protection , petrochemical and other industries have been widely used. The clamp type flexible pipe joint is such that the clamp is stuck on the positioning ring of the pipe to ensure that the axial tension is not pulled when the axial tension is sufficient. Compared with flanges, bolt fastening is simple, convenient and reliable. The seal ring of the clamp type flexible pipe joint has a structure of type C. The elasticity of the apron can be used to seal the pipeline. When the clamp is installed, the height of the rubber ring is higher than the height of the tube and the clamp, and the rubber ring is further squeezed by the inner space of the clamp, and the internal pressure is generated throughout the entire surface of the rubber ring, and the sealing effect is further enhanced. When the medium exists in the pipeline, the medium enters the C-shaped cavity and acts on the sealing lip of the apron, which increases the adhesion of the rubber ring and the pipe, thereby achieving self-sealing. The greater the fluid pressure in the pipe, the greater the pressure of the apron and the better the sealing performance.

ShandongExcellent Pipeline Technology Co., Ltd. uses the Hunter wire molding machine imported from the United States for casting. The casting process is fully automated, which effectively guarantees the stability of product quality and eliminates the blisters and sands that are easy to occur during the casting process. , water wave and other defects.The company’s high-pressure pipe clamps are widely used in coal mine pipeline installation. Due to the high pressure of the high-pressure pipe clamps, the normal working pressure reaches 10.5MPa, the UL test pressure can reach more than 20 MPa, and the installation has certain flexibility. The application has been well received and the products have been distributed throughout the country.The pipe material of the company is in accordance with American Society for Materials Engineering ASTM A 536 grade 65-45-12. The tensile strength of the material is 450Mpa, the yield limit is 310Mpa, and the elongation is more than 12%, which provides sufficient strength and toughness for the pipe fittings.The company’s apron formulation and process design meets the US ASTM D2000 and UL standard test requirements. Depending on the fluid medium used, we can provide different aprons. The sales of the rubber ring are subjected to hardness, tear strength, elongation at break and hardness change after the hot air aging and tear strength change, elongation at break test to ensure the safety of the sales apron in use. Sex.The company’s bolts are imported bolts that meet the US ASTM A-183 standard. It adopts 8.8 grade, low carbon alloy steel, quenched and tempered, the minimum tensile strength is 800Mpa, and the yield strength is 640Mpa. The sufficient strength can prevent the possibility of bolt breakage accidents in large-volume applications.The company provides the rolling groove machine in the customer’s distribution, and for the new customers, the company’s technical personnel are free to send on-site guidance to the installation and commissioning. For the problems that arise in the future installation process, the after-sales service personnel of the company receive the call within 24 hours. Arrived on the spot to solve.

Grooved pipe joint technology, also known as clamp connection technology, has become the first technology for the connection of liquid and gas pipelines. Although this technology is developed later in China, due to its advanced technology, it is quickly adopted domestically. Received by the market. Since its development in 1998, it has gradually replaced the two traditional pipe connections of flange and welding after just a few years of development and application. Not only is the technology more mature, the market is generally recognized, and it has been actively guided by national laws and regulations.The application of the grooved pipe connection technology makes the complicated pipe connection process simple, fast and convenient. Make pipe connection technology a big step forward.
