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.
Polytetrafluoroethylene (PTFE) has a series of excellent performance:
High temperature resistance: long-term use temperature 200 ~ 260 degrees;
Low temperature resistance: still soft at - 100 degrees;
Corrosion resistance: resistant to aqua regia and all organic solvents;
Weather resistance: the best aging life of plastics;
High lubrication: with the smallest friction coefficient in plastics (0.04);
Non-stickiness: It has the minimum surface tension in solid materials and does not adhere to any substance;
Non-toxic: physiological inertia.
Product advantage
1.The HEBEIXINQIpump connector and expansion joint protects your pumps and reduces noise and vibration.
2.A durable joint for piping systems reaching temperatures up to 250°F (121°C), the HEBEIXINQI joint differs from standard EPDM expansion joints by integrating HEBEIXINQI cording and peroxide-cured EPDM. It is perfect for high-temp applications requiring modest pipe movement/expansion at higher temperatures.
3.The rugged, long-lasting material and construction will provide years of trouble-free operation at high temperature.An anchor wire, fully-wrapped with HEBEIXINQI corded material, ensures a positive seal between the body and the floating flange.
4.The HEBEIXINQI Style rubber expansion joints are furnished complete with plated carbon steel flanges for corrosion protection. Q235 other 304 or 316 stainless steel flanges are available upon request as well as ANSI 150/250/300 lb., BS-10, DIN PN10 & PN16 and JIS-10K drilling.
5.HEBEIXINQI reinforced, peroxide-cured EPDM rubber greatly enhances tolerance to high temperatures.Anchor wire wrapped with HEBEIXINQI corded material ensures a positive seal between the body and the floating flange.Reduces noise and vibration.Isolates and protects the pump.Available in single and double sphere styles.
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.Rubber material of JGD flexible rubber joint
