Flange concentric reducer rubber joint acid and alkali resistance
Rubber materials are divided into two categories: general-purpose rubber and special rubber. General-purpose rubber refers to rubber that can partially or fully replace the rubber used in pure natural rubber, such as styrene butadiene rubber, isoprene rubber, cis-butyl rubber, etc. It is mainly used in the production and manufacture of a wide variety of car tires and general industrial rubber products. General-purpose rubber has a strong market demand and is an important type of rubber generation. Special rubber refers to the rubber with the advantages of heat resistance, acid and alkali resistance, active oxygen resistance, aging resistance and high sealability.
Sewage generally to not to acid alkaline or for the alkaline, so compared to the cooling circulating water sewage media variability, the rubber material used in the specified pipeline compensator for the import of special corrosion-resistant rubber, the general cooling circulating water pipeline joints are applied to domestic neoprene generated rubber can be. Sewage pipeline rubber shock absorbers are used in an environment where rubber has very good resistance to abrasion. Since the residue in the sewage is basically operating in the pipeline along with the water flow without any deposition, the abrasion-resistant rubber joints can prevent the pipeline from being damaged and thus aggravate the leaching. Is it easy to ignore these key points in the use of pipeline rubber joints? For the pipeline working pressure is not a comprehensive consideration: when the pipeline runs a moment working pressure > 1.0mpa, it is appropriate to choose a joint with 1.6mpa in work. When to choose 5pa rubber joints? It should be selected when the instantaneous pressure is greater than 1.6pa, i.e., one block is raised. In pipeline commodity circulation medium is strong acid and alkali, oil, continuous high temperature and other unique chemical substances, avoiding the pressure on the pipeline due to harmful gas or atmospheric aerosol body boosting the medium itself, using rubber joints with one stop higher than the pipeline pressure is guaranteed.
