Internal Pressure Bellows Compensator

Product Description

Internal Pressure Bellows Expansion Joint, also known as Internal Pressure Bellows Compensator, is a common type of metal expansion joint designed to absorb axial thermal expansion and contraction in straight pipeline systems. The flexible stainless steel bellows element expands and contracts under temperature changes, reducing thermal stress and protecting pipelines and connected equipment.

This type of expansion joint is mainly used in steam pipelines, hot water systems, chemical pipelines, power plants, petrochemical facilities, and industrial process piping systems where internal pressure acts directly on the bellows.

Key Features

Reliable Axial Movement Compensation
Effectively absorbs axial expansion and contraction caused by temperature fluctuations in pipeline systems.

Simple & Compact Structure
The internal pressure design provides a simple structure with easy installation and maintenance.

High Pressure Resistance
Manufactured with high-quality stainless steel bellows to withstand internal pipeline pressure.

Excellent Fatigue Performance
Designed for repeated expansion and contraction cycles with long service life.

Reduce Pipeline Thermal Stress
Helps minimize stress caused by thermal expansion and protects pipelines and equipment.

Customized Design Available
Available in different sizes, materials, pressure ratings, and movement capacities according to project requirements.
