Product Introduction

JWY type unconstrained bellows compensator is also called unconstrained bellows, unconstrained expansion joint, direct buried compensator. The bellows in the compensator are single-layer, double-layer or multi-layer U-shaped waves. The bellows and guide sleeve are made of austenitic stainless steel such as 1Cr18Ni9Ti, and other materials are low-carbon steel or low-alloy steel.

The determination of fixed support spacing and calculation of fixed support thrust for unconstrained ripple compensators are identical to ordinary axial compensators.

The unconstrained ripple compensator not only eliminates pre stretching work, but also greatly loosens installation requirements.

The unconstrained corrugated compensator can be installed in the pipeline like a short pipe. It is not necessary to cut the pipe of the same length as the expansion joint after the whole line of steel pipe is connected as required by other axial expansion joint. Due to the sturdy shell of the unconstrained ripple compensator, it also facilitates transportation, installation, and insulation.

The unconstrained ripple compensator is used for axial compensation of pipelines, with a large compensation amount, strong self guidance and super strong bending resistance, which can simplify the design of pipeline guide brackets and allow for arbitrary adjustment of the spacing installation of guide brackets.

Product advantages

Unconstrained ripple compensator is used for axial compensation of pipelines, with a large compensation amount, strong self guidance and super strong bending resistance, which can simplify the design of pipeline guide brackets and make the spacing of guide brackets installation arbitrary.

1. The determination of the spacing between fixed supports and the calculation of the thrust of fixed supports for unconstrained ripple compensators are identical to ordinary axial type compensators. In order to ensure the stability and reliability of the project, the unconstrained compensator requires not only installation close to the fixed bracket, but also three guide brackets within the spacing of each fixed bracket.

2. Unconstrained compensators can be applied to overhead and trench laying of pipelines, as well as directly buried laying with compensation. In this case, inspection wells or dark rooms should be installed at the location of unconstrained compensators.

3. The unconstrained ripple compensator is used for axial compensation of pipelines, with a large compensation amount, strong self guidance and super strong bending resistance, which can simplify the design of pipeline guide brackets and allow for arbitrary adjustment of the spacing installation of guide brackets.
