Advantages for Grooved Type Metal Bellows Expansion Joints


Our company (Shandong Hesper Rubber Plastic Co., Ltd.) have various of expansion joints: metal expansion joints and non-metallic expansion joints. For metallic expansion joints, also have many types, Grooved metal bellows expansion joints is a new type of steel pipe connection joints, here let’s know some advantages for its connection.

1. Simple operation

The connection operation of grooved metal bellows expansion joints is very simple, no special professional skills are required, and ordinary workers can operate after simple training. This is because this kind of expansion joints has integrated a large number of fine technical parts into the product in a factory, only takes a few minutes to connect a pipe fitting, which greatly simplifies the technical difficulty of on-site operation and saves man-hours, thereby stabilizing the project quality and improving work efficiency. This is also the general direction of the development of installation technology.

Meanwhile, because the grooved expansion joints finished products, the operation space required on site is small, and it can be installed against the wall and corner, and the operation difficulty is greatly reduced, thus saving the floor area and beautifying the pipe installation effect.

2.The original characteristics of the pipe are not affected.

The connection of grooved expansion joints only extrudes a groove on the outer surface of the connected pipe with a rolling groove machine without destroying the inner wall structure of the pipe. This is a unique technical advantage of grooved type metal bellows joints.

3.Conducive to construction safety

Adopting grooved pipe fitting connection technology, only cutting machine, rolling groove machine and wrench for tightening bolts are needed on site, and the construction organization is convenient.c

4.Good system stability and easy maintenance

The grooved pipe fittings connection has a unique flexible feature, which makes the pipeline have the ability to resist vibration, shrinkage and expansion. Compared with welding and flange connections, the stability of the pipeline system is increased, and it is more suitable for temperature changes, thus protecting The pipeline valve parts are reduced, and the damage to structural parts caused by pipeline stress is also reduced.

5.Economic Analysis

The connection operation of grooved expansion joints is simple, labor-saving and time-saving, so it has good economic benefits.
