Double flange limited telescopic joint is loose telescopic joint and a short pipe flanges limit combination of expansion joints in the loose set of the original performance based on the additional stopperExpansion at the maximum amount of double nut lock. The amount of pipeline stretching allowed the freedom to stretch, once more than the maximum amount of stretch to play a limit to ensure the safe operation of the pipeline is mainly used in the Allows absorption of axial displacement within the displacement and the axial pressure thrust, Loose pipe connections suitable for a vibration or a certain slope and bend the pipe connection. It can prevent the pipeline due toOver-compensation for the displacement caused leaks and damage to the joints.

Advantages: scalable capacity, easy installation and quick.
Features: For both ends of the pipe above the flange connection
Connection: flange type, working pressure : 0.6-1 . 6 MPA,
Nominal by : 65-3200mm, use of media: water, sewage.
Temperature: ≤ 170 ℃, sealing materials: NBR,
Manufacturing standards: ANSI
Install a brief description: VSSJA-2 dual flange limit applies to both sides of expansion joints and flange connections at both ends of the adjustment of product installation, the connection with the flange length, angle of turn of the uniform
Tighten gland bolts, nuts, and then adjust the limit so that we can make within the pipes in the amount of free telescopic retractable, locking telescopic quantity, to ensure the safe operation of pipelines.

Concrete expansion joint classification: BF (VSSJA-1)-type single flange limited telescopic joint, B2F (VSSJA-2) Double flange limited telescopic joint BY (SSJB-3) type of gland-type limit expansion joints,
AY (SSJB) type of gland-type expansion joints, flange limit expansion joints, flange loose set of expansion joints.
