End face seal rubber joint, the flanging EPDM acidproof alkali in a flexible rubber joint, can be overly acidic alkaline medium, the product material is composed of EPDM EPDM sulfide, has excellent physical performance in a flexible; Excellent corrosion resistance, acid and alkali resistance; The use of non-toxic gas blowing mold production surface smooth, does not breed microorganisms, not easy to accumulate dirt. Suitable for DN100 to DN3200 all calibers, easy to install. Acid and alkali resistance can be sustainable for 30 years without failure under normal use environment.

Key words: acid and alkali resistant rubber joint,EPDM flexible rubber joint, over acid and alkali rubber joint, large flanged acid and alkali resistant rubber joint

Common pipeline flow acid and alkali medium is generally transported by four-fluoride lined pipe, acid and alkaline fluid, at present, such acid and alkali transport pipeline is mainly used in chemical anti-corrosion engineering, including: power plant, fuel, sewage treatment, caustic soda, desulfurization and other pipelines. In addition to the important link of pipeline anticorrosion, the acid and alkali anticorrosion engineering is followed by the anticorrosion performance of the flexible rubber joint connecting the pipeline fittings.

Ningtai Hydropower large flanging EPDM acid and alkali resistant flexible rubber joint, can be over acid and alkaline medium, Ningtai hydropower for many years in the pipeline acid and alkali technology under the continuous scientific research and innovation. This series of EPDM in a flexible rubber joint has won each big chemical industry specified product quality certification, the products material is composed of EPDM EPDM sulfide, has excellent physical performance in a flexible; Excellent corrosion resistance, acid and alkali resistance; The use of non-toxic gas blowing mold production surface smooth, does not breed microorganisms, not easy to accumulate dirt. Suitable for DN100 to DN3200 all calibers, easy to install. Acid and alkali resistance can be sustainable for 30 years without failure under normal use environment.
