Name: VSSJA-1-type single flange limited telescopic joint
flange limited telescopic joint is set in the AF-type Falan Song additional compensation on the basis of joint stud from the limit, the maximum amount of stretching at the double nut lock, compensation foundation settlement due to thermal expansion and contraction caused by the pipeline and the axial displacement and the deflection and eccentric, to protect the valve device. According to the different connections into a single flange limited telescopic joint and dual flange limited telescopic joint.
Single flange limited telescopic joint application
VSSJA-1 single-flange limited telescopic joint is suitable for conveying water, fresh water, hot and cold water, drinking water, sewage, crude oil, fuel oil, lubricating oil, oil, air, gas, the temperature is not higher than 250 degrees of steam and particle powder and other media.
Single flange limited telescopic joint installation instructions:
VSSJA-1 single-flange limited telescopic joint and flange for the side, side and pipe welding, installation and adjustment of product at both ends of the length of pipe or flange installed on the angle turn evenly tighten the gland bolts, then adjust the limit nut so that we can make within the pipes in the amount of free telescopic retractable, locking telescopic capacity to ensure the safe operation of pipelines.
Single flange limited telescopic joint Features
a single flange limited telescopic joint, model VSSJA-1 or Type BF, single flange limited telescopic joint is a loose set of expansion joints and limit short-tube combination. VSSJA-1 single flange limited telescopic joint to prevent excessive displacement due to lead pipe joints for leaks or damage compensation, mainly for absorption within the allowable displacement axial displacement and axial pressure thrust of the pipe loose set of connections.
Single flange limited telescopic joint Advantages: quick and easy installation, reliable sealing, easy maintenance.
Single flange limited telescopic joint features: realization of the pipeline side of the flange, while convenient for the welding of the inconsistency connection.
