Straight tube pressure balance type and steering type expansion joint

Product description

Straight pipe pressure balance type and steering type expansion joints are used to compensate the axial displacement of the pipe system, internal pressure thrust self-balance, straight pipe pressure balance type ripple compensator (expansion joints) is suitable for high straight pipe or large diameter pipeline where it is difficult or difficult to set the main fixed bracket.

Product structure features of straight pipe pressure balance type and steering type expansion joint

1. There is a working bellows at both ends of the corrugated expansion joint, and a balance bellows in the middle. The corrugated expansion joint bears the internal pressure thrust through the stress member (big pull rod or tongue tube), so the pipe system only needs the middle fixed bracket.Such corrugated expansion joints can only absorb axial displacement

2. There is a working bellows at both ends of the bellows expansion joint, and a balance bellows in the middle. The bellows expansion joint bears the internal pressure thrust through the stress member (big pull rod or tongue tube), so the pipe system only needs the middle fixed bracket.Such bellows expansion joints can only absorb axial displacement.

Parameters

Notes for installation and use of straight pipe pressure balance type and steering type expansion joints

1. Straight pipe pressure balance type ripple compensator (expansion joint) is generally applied to the straight pipe line overhead, installed horizontally.

2. After the installation of the straight pipe pressure balance type ripple compensator (expansion joint), all the small tie rods shall be removed.

3. In order to reduce the elastic reaction of the bellows expansion joint to the support, the bellows expansion joint can be pre-pulled or pre-pressed before installation (it can be achieved by adjusting the small tie rod on it).
