Product Description
Material Description:
EPDM-Good heat resistance and suitable for alkaline waste water,compressed air terpolymer(oil free) and chemicals,weather- resistance,good gas tightness except for hydrocarbon.
NBR-Oil and fuel quality,also suitable for gases,solvents and fats.
Rubber expansion joint Details:1.The raw material of flexible rubber expansion joint is high quality rubber,and the content of natural rubber is more than 50%.2.The flange of JGD flexible single sphere rubber joint is made of high quality steel,large CNC machine,galvanized surface and standard flange typing.3.All rubber expansion joints are finished with retaining flanges,and limit rod units are available on special request.
Polytetrafluoroethylene (PTFE) has a series of excellent performance:
1.High temperature resistance: long-term use temperature 200 ~ 260 degrees;
2.Low temperature resistance: still soft at – 100 degrees;
3.Corrosion resistance: resistant to aqua regia and all organic solvents;
4.Weather resistance: the best aging life of plastics;
5.High lubrication: with the smallest friction coefficient in plastics (0.04);
6.Non-stickiness: It has the minimum surface tension in solid materials and does not adhere to any substance.
7.Non-toxic: physiological inertia.

Product installation
Installation of JGD flange type rubber joint:
1. Rubber joints are strictly prohibited from installation during the installation.
2. Installation bolts should be symmetrical and gradually pressurized to prevent local leakage.
3.1.6MPa above working pressure, installation bolts should have elastic pad to prevent bolts loosening when working.
4. Vertical force support should be provided at both ends of the joint pipe during vertical installation, and anti-pull-off device can be adopted to prevent working pressure pull-off.
5. Rubber joints should be installed away from the heat source. Ozone zone zone. Strictly prohibit strong radiation light exposure and the use of non-conforming media.
6. Rubber joints shall be strictly prohibited from cutting the surface and sealing surfaces during transportation and handling.
Notes:
1. Rubber soft joint should not be installed beyond the limit of displacement.
2. Pipeline must have fixed support or bracket, and the force of fixed bracket must be greater than the axial force.
3. When installing vertically or overhead, fixing brackets and stress brackets should be installed at both ends of the product to prevent pulling-out after working under pressure.
