Metal Expansion Joint
Metal expansion joints (also known as stainless steel expansion joint) are flexible connectors designed to absorb thermal expansion, vibration and misalignment in piping systems.
With TOT’s precision-engineered bellows, you can protect your equipment from fatigue, pressure surges and thermal stress without compromising flow or safety.
Our OEM and custom expansion joints are used in a wide range of industries including oil and gas, aerospace, power generation, petrochemical, water supply and wastewater treatment.
Are you looking for a flexible solution to manage pipe stress and thermal displacement?
As a reliable metal expansion joint manufacturer, TOT’s carefully designed industrial metal expansion joints absorb displacement, reduce vibration and extend the life of your piping system even in the most demanding industrial environments.
- All stainless steel construction
- Customized sizes and displacement types
- Meets ASME/EJMA standards
- Fast global delivery
Be careful when choosing a new valve supplier, the disappointment of poor quality can last much longer than the joy of a low price!

FAQ
A metal expansion joint is designed to absorb thermal expansion, vibration, and mechanical movement in piping systems, helping to reduce stress and prevent damage or failure at connection points.
Metal expansion joints are suitable for high-pressure and high-temperature applications, offering better strength and durability. Rubber joints, while more flexible, are limited to lower pressure/temperature conditions and are more prone to aging.
You should consider movement direction (axial, lateral, angular), operating pressure, temperature, media compatibility, and installation space. TOT team can help you select or customize the right joint based on these factors.
Typical lifespan ranges from 5 to 15 years depending on operating conditions, material selection, and system design. Proper installation and regular inspection significantly extend service life.
Yes, stainless steel expansion joints are commonly used in steam systems due to their ability to withstand high temperature and pressure while managing pipe growth and vibration.
Absolutely. We provide fully customized solutions including size, material, movement capacity, and end connections—tailored to your system’s exact needs.
Yes. While their primary role is to absorb movement, metal expansion joints also help reduce vibration and noise transmission, especially in pump and turbine lines.
We can provide you with flange, welding or threaded end types to install in your system, depending on your pipe configuration. But be sure to follow the installation guidelines and calibration instructions to avoid premature failure.
