Qingdao Acoustic Pipe manufacturers 18134186469- Zhao Lei -18,134,186,469 its Double Double seal clamp compression at the top end of the socket set out two convex slot inside its own ring, at the time of installation of this product will be inserted into the socket end socket end, and then at the same time using a hydraulic clamp to implement the two convex slot extrusion, then is extruded into a pipe where occurs after contraction deformation force, the groove between two convex outer pipe deep into the inner pipe, thus effectively solved the trusted connection to the product; and at the same time in the rubber material deformation after being squeezed between two tubes attached to clothing, played a very good seal double insurance effect. While welding clamp compression joints of their first single in the top has been formed, but which on the other end of the tube inserted into the double-groove joints, hydraulic crimping force reduction, and thus led to its joint is tightly together, has a dual seal in the middle of its place, thus making it more possible to seal, if such a single head of the clamping type, requiring only one clamping on it . Advantages: 1, the use of specialized hydraulic clamp conducted convergence, is ready to work outside of the site do not need, do not need all the equipment, convenient, easily fixed to the steel cage, two from harsh weather, can according to the Demand from the field on a long trip with no loss. 3, the product is a patented product and market conduct in the same kind of product comparison, more high in tensile strength, and has reached more than 320Mpa (typically about other products tensile strength 30Mpa). 5, saving the cost and time needed to prepare to use, does not require skilled workers, loss of savings, there will not be restricted site. 6, very safe, does not require welding work carried out on site. 7, which uses a deformable material, making the local connection as well as the emergence of a large middle two small situation, leading to the occurrence of a one-time connection stuck, avoiding the possibility of a loose union. Whether in the drawing or in resistance to resist the anti-torque performance is represented by very stable and good, and bumps into a circular, small bumps degree, effectively prevent and catheters, vibrators and other collide.
