Custom Color double tied expansion joint bellows with tieds

Product introduction

Compound tie rod transverse corrugated expansion joint: it can compensate the transverse displacement in any plane of the curved pipe, and can also withstand the pressure thrust generated by the internal pressure of the pipeline medium.The bellows expansion joint of the transverse tie rod is a flexible part composed of two bellows connected by the intermediate pipe with the same geometric parameters and wave number, and the tie rod and end plate.It is mainly used to compensate the transverse displacement of the curved tube sections.Suitable for "L" and "Z" type piping.Because the tie rod can bear the action of pressure thrust and other additional external forces, the expansion joint itself absorbs the internal pressure thrust and will not produce external forces on the pipeline. Therefore, the pipeline at both ends of the expansion joint can use intermediate fixed support or guide support to reduce the construction cost and improve the construction efficiency.

Product features

Compound tie rod transverse corrugated expansion joint: by the connection, two bellows and tie rod components.It can absorb the transverse displacement in any plane of the pipe system.The displacement spherical nut rotates around the spherical washer and the pull rod has the ability to withstand internal pressure thrust.The bellows expansion joint of the transverse tie rod is composed of two bellows connected by the intermediate pipe and the tie rod, end plate, spherical and conical washers, etc. It mainly absorbs the transverse displacement, and can also be used to compensate the axial, transverse, angular and arbitrary displacement combined by these three forms.It is recommended to install the double pull rod type expansion joint in the middle short pipe arm of the 90° z-shaped pipe to compensate for the axial displacement of the long pipe at both ends.

Installation work

1. After the arrival of the compensator, the following contents shall be unpacked for inspection:

Documentation: check whether the model, specification and technical parameters listed on the compensator label and qualification certificate are consistent, and whether other required technical documents are complete.

Appearance inspection: the compensator has no obvious scratch or sharp indentation;There should be no foreign body inside the compensator (trough);The connection ports should be in good condition. If the sealing surface of the flange connection should be free from penetrating scars, the coating should be free from peeling, cracking and peeling, and the large tie rod, transport tie rod and fasteners should be complete.

2. Matters needing attention in hoisting and transportation of compensator:

When hoisting, special hoisting fixture or lifting lug shall be used, and transport tie rod shall not be used as load bearing part.A small - bore compensator without lifting lug can be attached to the joint with rope because of its light weight.

Transport, storage process to prevent the sun and rain, water immersion, harmful gas corrosion.

Transport, storage process to prevent falling, collision, do not pile up with other items together, so as to avoid damage to the bellows.

The transport process to be bound firmly, to prevent the movement and rolling.
