Introduction to Double Flange Limit Expansion Joint
The double flange limit expansion joint is composed of main components such as the body, sealing ring, gland, expansion short pipe, etc. The double flange limit expansion joint adds a limit device on the basis of the original performance of the loose sleeve expansion joint, and uses double nuts to lock at large expansion amounts. The pipeline can freely expand and expand within the allowable expansion and contraction amount, and once the larger expansion and contraction amount is exceeded, the limit will be set to ensure the smooth operation of the pipeline. It is particularly suitable for connection in pipelines with vibration or certain slope and bends.
Purpose of double flange limit expansion joint
Double flange limit expansion joints are suitable for transporting seawater, fresh water, cold and hot water, drinking water, domestic sewage, crude oil, fuel oil, lubricating oil, product oil, air, gas, steam and particulate powder with a temperature not higher than 250 degrees Celsius.
The VSSJA-2 double flange limit expansion joint is suitable for connecting both sides of the product to the flange. During installation, adjust the connection length between both ends of the product and the flange, tighten the gland bolts diagonally and evenly, and then adjust the limit nuts. This allows the pipeline to freely expand within the expansion range, locking the expansion amount, and ensuring the operation of the pipeline.
