Product Introduction
Flange sleeve type pipe expansion joint and pipe expansion joint are compensation devices for hot fluid pipes, mainly used as auxiliary devices for straight pipes. It is applicable to hot water, steam, grease and other media. The sliding sleeve can compensate for thermal expansion by sliding the outer sleeve.Product Features
The service life of flange sleeve compensator is long, and its fatigue life is equivalent to that of pipeline. After special treatment, the sliding surface has good corrosion resistance in salt water, salt solution and other environments, more than 50 times higher than austenitic stainless steel. At the same time, if the sealing effect is weakened due to wear many years later, the flange can be tightened again to enhance the sealing performance, or the bolts can be loosened, the pressure ring can be removed, and then one or two layers of sealing ring can be installed, and the pressure ring can be compressed for further use.Applicable Conditions
