Performance characteristics
The limit device is used in reasonable combination with flexible rubber joints, in pipe-like connections or in pipelines with displacement requirements When in use, it can play a role in limiting the displacement. When the flexible rubber joint is connected to the pump valve, a limiting device is equipped on the flexible rubber joint to transmit force. It is a steel force transmission joint. ideal alternative product.
Flexible rubber joints for natural gas pipelines
Gongyi Chengxiang Water Supply Materials Co., Ltd. specializes in the production of various pipeline accessories. Our company has recently developed a new product using high-quality corrosion-resistant rubber that is suitable for long-distance pipeline compensation of natural gas pipelines. The rubber expansion joint has good corrosion resistance. 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 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 a small amount 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 operations, various countries have stipulated the quality standards of gas entering gas pipelines, which generally include stipulating the hydrogen sulfide moisture dew point in natural gas and other standards. Pipelines are determined according to the population density index of the areas they pass through. The design coefficient, the method of determining the minimum thickness of the pipe wall, formulating the fire safety distance, stipulating the welding performance of the steel selected for the pipeline, the impact toughness and crack arresting performance, and stipulating the sulfur resistance properties of the pipes selected for transporting natural gas pipelines that do not meet gas quality standards. wait. 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 is necessary Use compensator, welcome to use our company's products to ensure the operation of your pipeline.
