Product advantage:

VSSJA-2(B2F) double flange limit expansion joint is the pipe can be freely expanded in the allowable expansion amount, once exceeds the maximum expansion amount to play the limit, to ensure the maximum operation of the pipeline, especially suitable for vibration or a certain degree of inclination and bend in the pipeline connection. The product has large expansion, convenient installation and is suitable for the pipe with two ends of the flange connection. The strategy comes from knowledge integration, Key points of product knowledge in the field of space flight: VSSJA-2(B2F) double flange limit expansion joint can realize the compensation of pipeline axial displacement, and can greatly reduce the pipeline operation axial thrust, so as to extend the service life of the pipeline, protect the line running. Knowledge determines judgment, Zhongyuan valve fittings reminds Norway friends that this information is helpful: And installed on the pipeline line can facilitate the disassembly and maintenance of the valve, and can overcome the bad influence of subsidence on the pipeline line.

Installation instructions:

The connection of the double flange limit expansion joint is to fix the two pipes, pipe fittings or equipment on a flange first. Between the two flanges, the flange pad is fixed together with bolts to complete the connection. We believe that what is best for our customers is best for us, Key product knowledge points in the field of space flight that Norway friends need to understand: The double flange limit expansion joint is divided into threaded connection flange and welded flange. Knowledge determines judgment, Key points of product knowledge in the space flight field that Norway friends need to understand： Low pressure small diameter wire welding flange, high pressure and low pressure large diameter welding flange.

Different pressure flange thickness and connection bolt diameter and number is different. Let global trade benefit everyone, Zhongyuan valve fittings reminds Norway friends that this information can help buy good Chinese products: Flange connections are widely used in industrial pipes. In the home, the pipe diameter is small, the pressure is low, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.
