Special flexible rubber joints for natural gas pipelines Gongyi Chengxiang Water Supply Materials Co., Ltd. is a manufacturer specializing in the production of various pipeline accessories. Our company has recently developed a rubber expansion joint suitable for long-distance pipeline compensation of natural gas pipelines using high-quality corrosion-resistant rubber. It has good performance As a professional corrosion-resistant flexible rubber joint expansion joint for natural gas pipelines, our company's products have been used many times in coal-to-gas and natural gas pipelines. The chemical composition and physical and chemical properties of natural gas vary from place to place. The main component is methane, and also contains small amounts of ethane, butane, pentane, carbon dioxide, carbon monoxide, hydrogen sulfide, etc. It is a colorless and odorless gas without hydrogen sulfide, so the gas in the natural gas pipeline is very corrosive. Rubber joints based on the principle of corrosion-resistant flexible rubber joints are much more effective than stainless steel bellows and steel expansion joints. Good corrosion resistance, especially in outdoor environments, rubber joints are basically free of maintenance during operation, as long as they are manufactured and manufactured. The general service life is more than one year, which is incomparable to ordinary steel expansion joints and stainless steel bellows. , but compared to the price, flexible rubber joint expansion joints also have their own incomparability.
In order to ensure the safety of pipeline operation, various countries have stipulated the quality standards of gas entering gas transmission pipelines, which generally include stipulating standards for hydrogen sulfide, moisture, dew point and other standards in natural gas. Pipelines determine the quality of each gas according to the population density index of the area they pass through. Design coefficients for similar areas, methods for determining the minimum thickness of pipe walls, formulating fire safety distances, stipulating the welding performance, impact toughness, and crack arresting performance of the steel selected for pipelines, and stipulating that the pipes selected for transporting natural gas pipelines that do not meet gas quality standards should have Anti-sulfur properties, etc. Our company's flexible rubber joint expansion joints are designed and manufactured using the latest molds. The end-face fully sealed flexible rubber joint has tighter pipe sealing. Compared with ordinary direct flange connections, an additional layer is added between the flanges. The rubber sealing layer ensures the safe and effective operation of the pipeline without leakage. The soft performance of the rubber joint can also compensate for the displacement and ground subsidence of long-distance coal gas and natural gas pipelines. Generally, the displacement of meters of long-distance pipelines is 3 meters, so it must be Use compensator, welcome to use our company's products to ensure the operation of your pipeline.
