The practical use of drainage expansion joints

The practical use of drainage expansion joints
Expansion joints in practice because they have this commonality in the pipeline connection, so they have a complementary, interchangeable alternative role in the use of pipeline connections, only in specific cases selected a certain model series of pipe fittings joints used. Expansion joint installed in the pipe nut tight retaining ring in the gland nut, due to the influence of each other under the slope, pressure and the role of the outer ring of the connection pipe seal. The practical use of drainage expansion joints.
Expansion joints in practice because they have this commonality in the pipeline connection, so they have a complementary, interchangeable alternative role in the use of pipeline connections, only in specific cases selected a certain model series of pipe fittings joints used. The expansion joint is installed in the pipe nut tight retaining ring in the gland nut, due to the influence of each other under the slope, pressure and the role of the outer ring of the connection pipe seal. When the foundation sinks, the pipe can be tilted and ensure the seal without leakage, thus achieving the purpose of automatic compensation. Metal expansion joint loose short sleeve expansion joints, expansion joints or welded metal castings composed of loose casing site trapezoidal ring, rubber seals, bolts, screws under the rubber compression elastic deformation theory in the use of the effect gland, forcing the seal joint deformation degree circle in the body between the static seal exterior wall expansion extension tube.
Installation and maintenance can be adjusted according to the size of the site, axial thrust can be transferred to the entire pipeline, can protect the pipeline to improve efficiency. As double flange limit expansion joint belongs to metal products, high tensile strength, soft sealing performance, easy loading and unloading, widely used in electric power, metallurgy, chemical industry, water supply and drainage, sewage treatment and other industries. Double flange limit expansion joint mainly functions as the connection between valve and pipeline. Double flange limit expansion joint has certain multi-directional displacement in the pipeline operation, and has important expansion and contraction compensation for thermal expansion and contraction, crustal subsidence and force in the pipeline operation. Therefore, the double flange limit expansion joint can relieve the blind thrust in the pipeline operation and play a certain protective role for the pipeline.
