100% virgin material EPDM flanged rubber bellows installation suggestion
The official website of Shanghai Songjiang shock absorber Group Co., Ltd. introduces you: 100% virgin material EPDM flanged rubber bellows installation suggestion
The following is the Key factors for installation to obtain good performance and prolong the flange rubber bellows.
Fixed points:
An rubber bellows acts as a piston by the forces arising from the internal pressure. To prevent the pipes from damage they are to be properly anchored to take care of these reaction forces (Fr).
The Reaction force of an rubber bellows is calculated by the following formula:
Fr = Q x P x 0.01
Fr = reaction force in kN.
Q = effective cross-sectional area in cm2.
P = actual pressure in bar or KP/cm2
Installation:
The turnable metal flanges make installation easier and eliminate twists.
The low inherent rigidity of Songjiang rubber bellows makes for easier accommodation of installation dimensions.
Check the permissible movements, temperature, pressure, and proper rubber quality before installation!

100% virgin material EPDM flange rubber bellows installation suggestionThe rubber bellows shall be easily accessible and open to regular supervision. Lt is recommended to let the rubber bellows work in compression rather than stretching. Torsion is not permitted.Maintenance instructions: observe whether the rubber joint is overstretched and keep the flange rubber bellows at normal length every month.Pressure-restrained expansion joint on the pump (with tie bar).
Counter flanges:
The safe operating and life expectancy of the rubber bellows needs to make a proper installation of the counter flanges(Fig. 2 to 5). The sealing face of the counter flange must be machined smooth and cover most of the rubber sealing face(or at least 60%)to ensure good sealing(Fig.2).

Precaution:
Do not paint or lubricate rubber parts of rubber bellows!
When welding work is to take place the bellow has to be protected from welding heat and sparks!
Attention: Please strictly use the rubber fittings of the union according to the above requirements, if not used, cause any consequence, be not responsible for.
