Description

Technical Field

[0001] The utility model relates to the field of grooved pipe fittings, and more specifically, it relates to a composite grooved pipe fitting. Background Technique

[0002] Grooved pipe fittings are a type of metal pipe fittings, generally used for the connection between steel pipes, and are very common in projects that require water such as fire protection projects. The connection between steel pipes and the turning between steel pipes are realized through two sections of grooved pipe fittings and ordinary steel pipes. Generally, grooved pipe fittings are of an integral structure, and the steel pipe and the grooved pipe fitting are connected through a clamp. During the connection of steel pipes, generally, after the grooved pipe fitting is connected to one end of the steel pipe, there is a certain distance between the steel pipe on the other side and the grooved pipe fitting, making it impossible to connect the steel pipe on the other side to the grooved pipe fitting. Existing grooved pipe fittings lack an adjustment structure and have a fixed length, thus affecting the connection between steel pipes. At the same time, after the steel pipe and the grooved pipe fitting are connected, when they are used for a long time, they are prone to loosening, thus affecting the water flow in the steel pipe and causing problems such as leakage.
