  The connection process is simple to operate:

  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.

  Easy to install to reduce material 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.

  The original characteristics of the pipeline are not affected:

  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 maintenance cost is low in the later period:

  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.

PRODUCT ALBUM

INSTALLATION INSTRUCTIONS

1. It should be noted that the metal expansion joint does not absorb torque, so it is not allowed to be twisted when installing stainless steel bellows.
2. 2.In addition to the pre-tension or “cold-tight” deformation required by the design, it is strictly prohibited to use bellows deformation method to adjust the deviation of the installation pipeline, so as to avoid affecting the normal function of the metal bellows, otherwise it will reduce its service life and increase the load of the pipeline, equipment and supporting components.
3. The insulation layer should be made on the outer protective jacket of the metal bellows, not directly on the bellows.
4. During installation, no welding slag is allowed to splash on the surface of bellows, causing other mechanical damage to the bellows.
5. The bracket must meet the design requirements. It is strictly prohibited to test the pressure in the pipeline before the bracket is installed in order to avoid pulling it out.
6. All moving parts of the stainless steel 304L metal bellows shall not be caught or restricted by the external components.
