Use of stainless steel flanges

As far as the stainless steel flange product itself is concerned, it is a new product of water treatment and has the advantages of corrosion resistance and service life. It is an ideal supporting product for pump valve and hydropower industry. Stainless steel flanges are due to these advantages. It determines the logistics. The packaging market has a strong demand for it. The stainless steel flange is composed of loose flange and a short pipe. It is to add a limit device on the basis of the original performance of loose flange, and lock it with double nuts at the expansion and contraction. The pipeline can expand and contract within the allowable expansion and contraction amount. Once it exceeds its expansion and contraction amount, it plays a limit to ensure the operation of the pipeline. It is mainly used to absorb axial displacement and bear axial pressure and thrust within the allowable displacement range. The loose sleeve connection of the pipeline is especially suitable for the connection in the pipeline with vibration or certain slope and bend. It can prevent the leakage and damage of the compensation joint caused by excessive displacement of the pipeline. Stainless steel flange is mainly composed of body, sealing ring and bolt. Most stainless steel flanges are made of 16MnR, and the sealing ring is sealed with nitrile rubber, which has good water tightness and air tightness. The fasteners are nickel base stainless steel, with strong wear and corrosion resistance and long service life. The surface of stainless steel flange in contact with the medium shall be coated with epoxy resin paint with a coating thickness of 250 μ m. Strong corrosion resistance and sanitary dyeing, suitable for use in water or sewage environment. All parts, fillers and seals shall be made of non-toxic and harmless materials, and the surfaces of all stainless steel flanges shall be pickled and passivated. Simple structure, few parts and light weight. It is easy to install and can compensate the position and angle error of pipeline flange. The matching use of stainless steel spectacle blind flange brings great convenience to the maintenance of the valve. The expansion joint adopts standardized design. Similar parts are interchangeable and have a long service life. The overall trouble free working time is not less than 50000 h and the service life is not less than 20 years.
