Flanged Metal Expansion Joint
Flexible, Pressure-Rated, and Maintenance-Friendly – Built for Industrial Piping Demands
When your industrial pipeline system requires movement compensation with fast, flanged installation, a metal expansion joint with flanged ends is the go-to solution. Whether you’re dealing with thermal stress, pump vibration, or misaligned pipework, this flanged bellows expansion joint provides a durable, flexible, and leak-proof solution that integrates directly with your bolted connections.
Our flanged metal bellows expansion joints are engineered for durability, built to international standards, and ready for rapid delivery.
Description
This flanged metal bellows expansion joint consists of a corrugated stainless steel bellow designed to absorb multi-directional movement. It is terminated with welded flanges on both ends, enabling secure bolted installation to pumps, valves, tanks, or adjacent pipelines.
Ideal for high-temperature, high-pressure, and corrosive service conditions, these steel expansion joints with flanges are widely used in steam lines, chemical plants, and HVAC systems.
Made from premium stainless steel grades such as SS304, SS316L, our bellows offer excellent corrosion resistance and mechanical strength, making them suitable for high-temperature, high-pressure, and chemically aggressive environments.
TOT is a reliable expansion joint manufacturer and supplier that can not only provide you with stainless steel expansion bellows of various types, materials and sizes, but also customize them according to your requirements. Contact us now and let us support your business.

FAQ
What standards do your flanges follow?
ANSI B16.5 (150/300), DIN EN 1092-1 (PN10/16), JIS 10K, or customized drilling upon request.
Can I install this on a steam or hot oil system?
Yes, these high-temperature expansion joints are designed to handle up to 600°C in continuous operation.
Is gasket sealing required?
Yes, flanged connections require gaskets. We provide PTFE, graphite, or metallic options depending on your media and pressure class.
What’s the difference between single-ply and multi-ply bellows?
Multi-ply bellows offer greater flexibility, lower spring rate, and better fatigue resistance, ideal for cyclic systems.
Do you offer internal sleeves or flow liners?
Absolutely. For abrasive, high-velocity, or turbulent flow, internal liners protect the bellows and enhance flow stability.
