Medium use of EPDM Concentric reducing Non Metal Expansion Joint
Natural rubber: < 80°, ordinary water, domestic sewage, air conditioning circulating water, river water, cooling water, fire water, drinking water, pulp;
Noted usually overseas clients will require Neoprene Non Metal Expansion Joint to the pass-through same medium, Because Neoprene is an overseas common use material, and Chinese manufacturer need an import to get Neoprene raw material. so it is expensive about 30% more than a natural rubber-made rubber expansion joint. About 60-70% of Chinese manufacturers will sell natural Non Metal Expansion Joint as Neoprene Non Metal Expansion Joint when they know the pass-through medium is water so their price is not high than the market price. We are honest with all clients, you get the same product we promised. So best you get to know is if your client will accept the use of natural rubber if the drawing shows the material is Neoprene.
EPDM: <120°, boiling water, weak acid, strong alkali, seawater, food, beverage, natural gas, power plant lime slurry, power plant desulfurization, limestone, solar hot water, ground source heat pump, lithium electric acid, and alkali pipeline, automobile spraying, automobile electrophoresis, wastewater sewage, garbage leachate.
NBR:<115° hydraulic oil, emulsion, lubricating oil, thin oil, use for oil exploitation;
Nbr-special: <115° gasoline, diesel oil, aviation kerosene;
Lining PTFE: temperature <80°, strong acid, and alkali, aviation kerosene, petroleum, diesel, gasoline, (non-negative pressure vacuum)
Lining metal or vacuum support ring: if the pipeline has strong vacuum pressure, Lining metal or vacuum support ring Material carbon steel, stainless steel 304/316, according to the medium pass. common medium use carbon steel.
