Groove fittings include two major categories of products:
① The pipe fittings that play a role in connecting and sealing include rigid joints, flexible joints, mechanical tees, and grooved flanges;
② The pipe fittings that serve as transitional connections include elbows, tees, tees, reducers, blind flanges, etc.
The traditional pipeline connection method of welding and flange connection not only requires skilled welding workers, but also is time-consuming, difficult for workers to operate, and prone to welding smoke pollution. Due to differences in operating space and welding skills, it is difficult to achieve satisfactory results in welding quality and appearance, which affects the overall quality of the project.
In addition, as the groove fittings are finished products, the required operating space on site is small, and it is possible to install them against walls and corners, greatly reducing the difficulty of operation, thereby saving floor space and beautifying the effect of pipeline installation. The original characteristics of the pipeline are not affected by the connection of groove fittings. Only a groove is squeezed out on the outer surface of the connected pipeline using a groove rolling machine, without damaging the inner wall structure of the pipeline. This is a unique technical advantage of groove fitting connection. If traditional welding operations are used, many pipes with layered inner walls will be damaged. Therefore, the regulations stipulate that galvanized pipes, plastic lined steel pipes, steel plastic composite pipes, etc. shall not be welded or flanged, otherwise secondary treatment is required.
Due to the unique sealable structural design of its rubber sealing ring and clamp, the groove connection has good sealing performance, and its sealing performance is correspondingly enhanced with the fluid pressure inside the pipe
