American standard rubber joint flange is slotted flange, can be made of carbon steel or stainless steel. In most areas, it is mainly made of carbon steel. The surface of carbon steel flange has been galvanized. The flange of American standard rubber joint is forged once with steel plate, so it is also called forged flange, forged flange. Very good performance, can be used in various fields, high temperature resistance and compression resistance can be very good. The spherical material of American standard rubber joint is mainly natural rubber. It can also be changed to rubber of other materials. These depend on the transport medium in the installation area. For example, if the delivery medium is oil, NBR must be used for production, and at higher temperatures, fluororubber and solids must be used. The medium can be made from butyl rubber, while neoprene requires a certain acidity and alkalinity. For complex transport media, such as seawater, EPDM is required. Special u. s. standard rubber joints were installed in the special area to enable it to be displayed. One strong aspect of these special rubbers is that they cannot be used at will, otherwise the effect will be greatly reduced. The installation method of American standard rubber joint is very simple. The flanges at both ends can rotate freely. Therefore, when installing in the pipeline, it is necessary to tighten diagonally to avoid local leakage in the future. Since the spherical part of the NBR rubber joint is rubber, contact between metal and sharp boxes must be avoided. For surface quality requirements: no scratches, no bubbles, no defects on the sealing surface, and avoid direct contact with the sun. Reasonable use of rubber joints can last longer.
