Expansion joint introduce：

Pipeline compensation joint is a new product of pump, valve, pipeline and other equipment and pipeline connection, they are connected by bolts, so that it becomes a whole, and has a certain displacement, so that it can be adjusted in installation and maintenance, according to the site installation size, at work, the axial thrust can be transmitted back to the whole pipeline system. Let global trade benefit everyone, Key product knowledge points in the field of nuclear power that Aqaba friends need to understand: This not only improves work efficiency, but also plays a certain protective role in pipeline equipment such as pumps and valves.

Working principle：

The expansion of the pipeline is large, the temperature is high, and the compression area is strong. Continuous improvement: Make incremental improvements every day, Key points of product knowledge in the nuclear power field that Aqaba friends need to understand： In the construction water supply and drainage engineering, the foundation concrete pouring or embedded pipeline, in these engineering pipelines by building foundation settlement, equipment resonance, geological changes, pipeline medium changes in the process, the distribution of the pipeline begins to force, deformation, distortion and damage the pipeline, embedded pipeline even rupture to the construction unit brings great inconvenience, in order to overcome these difficulties, to ensure the operation of the pipeline, The use of expansion device, expansion joint: it can be in a certain range of axial expansion, to overcome a variety of Angle displacement of the pipeline, different heart, expansion, expansion. The pipe is free to expand in the telescopic device. Make your factory work easier, not harder, Zhongyuan valve fittings reminds Aqaba friends that this information is helpful: Once the maximum amount of expansion is exceeded, it plays a limiting role. To ensure the pipeline running!

Expansion joint the main functions are：

The importance of expansion joint in pipeline installation, expansion joint due to the connection of expansion pipe or bellows temperature change, the use of expansion joint is a protective measure, expansion joint is a pump, valve, pipeline and other equipment and pipeline connection of new products, through the whole bolt to connect them, make it a whole, and a certain amount of displacement, convenient installation. Can withstand pipeline axial pressure. Key points of product knowledge in the nuclear power field that Aqaba friends need to understand： In this way, the installation and maintenance can be adjusted according to the site installation size. When working, it not only improves the work efficiency, but also plays a certain role in protecting the pump, valve and other pipeline equipment.

Flanged loose sleeve expansion joint VSSJA or AF, flanged loose sleeve expansion joint is composed of body, gland, sealing ring and fastener. The flange loose sleeve expansion joint adopts the same sealing principle as the gland loose sleeve compensation joint. One end of the connection is flange connection, and the other end is socket connection. Reminder of product knowledge points for serving the Aqaba nuclear power industry: The flange loose sleeve expansion joint is suitable for the connection of valves and other equipment and pipes. The socket is also suitable for connection with steel pipe, cast iron pipe, ductile iron pipe,PVC pipe,ABS pipe, etc. Unlocking new opportunities with our trade expertise, Asia Aqaba Transmission joint Rubber lined double flange limit expansion device rest assured suppliers Zhongyuan valve fittings enterprise international customer site customer service Key Knowledge Reminder: At the same time, absorbing the advantages of similar products at home and abroad, the flange loose sleeve expansion joint has the advantages of simple and reasonable structure, reliable sealing performance, no need to weld, convenient installation and disassembly, the flange loose sleeve expansion joint can compensate the displacement, dislocation and deflection within a certain range of the pipeline and high reuse rate, the flange loose sleeve expansion joint is suitable for any medium pipeline, Used to connect valves, pumps and other equipment to pipelines.

Flange loose sleeve expansion joint product structure design is reasonable, reliable sealing performance, flange loose sleeve expansion joint at both ends of the socket connection, easy installation, disassembly, suitable for connecting the transmission of water, oil, gas and granular powder of the steel pipe, cast iron pipe, ductile iron pipe,PVC pipe,ABS pipe, flange loose sleeve expansion joint in the connection of the pipe can compensate the pipeline in a certain range of axial Displacement and deflection, eccentricity.

Application field：

The rubber lined double flange limit telescopic device has good comprehensive performance, so it is widely used in chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, freezing, health, water heating, fire protection, power and other basic engineering.

Working principle：

After the flange loose sleeve expansion joint is installed on the pipe, tighten the nut elastic sealing ring. Creating a brighter future for all, Zhongyuan valve fittings reminds Aqaba friends to understand this information: Under the action of the nut gland, the flange loose sleeve expansion joint tightly seals and connects the outer ring of the pipe depending on the mutual inclination. The flange loose sleeve expansion joint can expand freely in the middle of the joint when the temperature changes, when the foundation sinks, the pipe can be deflected, and ensure that there is no leakage, so that the flange loose sleeve expansion joint plays the purpose of automatic compensation.

Single flanged limit expansion joint VSSJA-1(GB/T12465-1999) or BF(GB/T12465-2002), single flanged limit expansion joint is a loose sleeve expansion joint and a limit short pipe combination. The single flange limit expansion joint can prevent the leakage or damage of the compensation joint due to the excessive displacement of the pipeline. ZhongYuan's customer service personnel reminds us of the key points of product knowledge in the field of nuclear power application: The single flange limit expansion joint is mainly used for the loose sleeve connection of the pipeline that absorbs the axial displacement and withstand the axial pressure thrust within the allowable displacement range.

The single flange limit expansion joint is to add a limiting device on the basis of the original performance of the loose sleeve expansion joint, and double nuts are used to lock the maximum expansion quantity. ZhongYuan are always mindful that all energy comes from the CUSTOMER, Zhongyuan valve fittings Reminder Aqaba Friends can refer to these knowledge: The pipeline can be freely expanded in the allowable expansion amount, once it exceeds the maximum expansion amount to play the limit, to ensure the maximum operation of the pipeline, the single flange limit expansion joint is especially suitable for vibration or a certain degree of inclination and bend in the pipeline connection.
