Function of limit expansion joint

What is the difference between expansion joints and limit expansion joints in terms of functionality, what is the difference between the surfaces, and what is the most suitable application for everyone's engineering projects to acquire that type? Let's get to know each other. Expansion joints and limit expansion joints are all components of pipeline connection, which can be connected with pipelines to become a whole, bringing a good guarantee effect to the operation of pipelines. Both expansion joints and expansion joints belong to expansion joint products, which are also called expansion joints, expansion joints, pipeline connectors, etc. But their actual efficacy is different. However, their actual efficacy differs from each other.
The primary function of expansion joints is to stretch and shrink in the pipeline to compensate for the deflection caused by vibration operation or heat rise and cold shrinkage of the pipeline, to facilitate the installation, disassembly, overhaul and maintenance of facilities such as gate valve centrifugal pumps, etc. The common expansion joints are expansion joints, monoflanged expansion joints, screw cap expansion joints, limit expansion joints, etc. The main function of expansion joint is to transmit radial driving force, which can connect valve accessories and pipeline into a whole, and its own foot bolt can adjust the installation length. The expansion joint excites the connection efficacy in the pipeline, and it is the machine and equipment that cannot be missing in the field of purifying water sewage treatment, and it is the stage that cannot be missing in all sewage treatment.
The disassembled expansion joint has itself, sealing ring, screw cap, reach reduction tube and other key components constituting the commodity is applicable to both sides of the pipeline connected with the flange when used to adjust the assembly length of both sides of the commodity and the flange, the top angle is evenly twisted tight valve cover foot bolt to apply it into a product with a certain offset amount convenient installation and maintenance according to the spot when the adjustment is carried out according to the spot specifications. In the operation can be anti-radial push force transmission to all pipeline. Application areas: This product is suitable for transporting sea, talk water, cold and hot water, domestic water, domestic sewage treatment, petroleum, gas and diesel oil, grease, wholesale refined oil, gas, liquefied gas, steam, granular powder and other substances whose temperature does not exceed 250 degrees. Material: off-loading type expansion joint material: ductile ink casting QT, carbon steel Q235,Q345, stainless steel plate 304,316.
