The groove type bellow expansion joint also called a clamp type bellows expansion joint. The groove type bellow expansion joint is a compensating element. Using the effective telescopic deformation of the corrugated pipe of the working body to absorb the dimensional changes caused by thermal expansion and contraction of pipelines, pipes, containers, etc., for compensating for axial, lateral and angular displacement of pipelines, pipes, vessels, etc. For example: a new type of special grooved type bellow for fire protection.
Super high temperature resistance, corrosion resistance, high pressure resistance
The connection process is simple to operate. The groove is connected to the grooved type bellow and the process is very simple and requires no special expertise. A pipe connection takes only a few minutes, which simplifies the technical difficulty of on-site operation and saves man-hours, thus stabilizing project quality, improving work efficiency and reducing labor costs.
Flange-connected metal hoses need to be paired with flanges, bolts, gaskets, and installation time. The grooved metal fittings do not have these fittings, which greatly reduces engineering costs. Used mostly in fire lines and water lines.
Grooved type bellow, only in the connected nozzle tube groove, without damaging the thickness of the tube wall, which is a technical advantage unique to the grooved type bellow process. The groove-connected bellow has a unique flexibility, which makes the pipeline anti-vibration, anti-shrinkage and expansion. Compared with welding and flange connection, the stability of the piping system can be enhanced, which is more suitable for temperature changes. This protects pipes, valves and equipment and also reduces damage to components by pipe stresses.
The grooved type bellow is simple for connecting the grooved pipe fittings, and the required operating space is small, which brings many convenient conditions for future maintenance. When the pipeline and valve equipment need to be repaired or replaced, just loosen the two groove clamps to replace, rotate, and modify a section of the pipeline. No need to damage surrounding walls, reducing repair time and maintenance costs.
