ANSI Standard Flanged Stainless Steel D-Type Large Deflection Compensator Expansion Joint

Product Introduction

D-type large deflection loose sleeve compensation joint is a commonly used compensation device in urban heating and gas pipelines, with double compensation function, suitable for displacement and axial thrust compensation. Its components include loose sleeve compensating joints, limiting devices, sealing rings and brackets. The working principle is that when the pipeline is displaced, the loose sleeve compensation joint can move freely, and when the displacement reaches a certain amount, the limiting device works, and the sealing ring maintains the sealing performance. In the design and installation, the displacement and direction of the pipeline should be fully considered, and the type and specification of the compensation joint should be reasonably selected.

How the product works

1. When the pipeline is displaced due to temperature changes or other factors, the loose sleeve compensation joint can move freely along the axial and radial directions of the short pipe to achieve displacement compensation.
2. When the displacement reaches a certain amount, the limiting device plays a role to prevent further displacement of the pipeline and protect the safety of the pipeline and support.
3. During operation, the sealing ring always maintains good sealing performance to prevent media leakage.

Product installation precautions

1. Avoid using the joint part as a lifting point: So as not to damage the pipeline and valve.
2. Avoid strong corrosive media or high-temperature and high-pressure pipelines: D-type large deflection compensation joints are not suitable for these environments.
3. Ensure that there are no impurities: Clean the pipeline before installation to ensure that the pipeline and joints are clean and free of impurities.
4. Pay attention to the direction and position of the joint: When installing, you should pay attention to the direction and position of the joint, and whether it is installed horizontally or vertically.
5. Avoid over-tight bending: Ensure that the compensating joint assembly does not produce over-tight bending, and the fluid medium will not cause excessive abrasion to the inner rubber layer of the compensating joint.
6. Model confirmation: When installing, it should be determined whether the model is correct, due to the large deflection loose sleeve compensation joint of many models, special attention should be paid when choosing.
