Joints Metal Bellows

We are manufacturer of Joints Metal Bellows to meet their individual requirements. Our strict manufacturing processes and quality control procedures insure a precise product every time. Single ply and multi ply bellows are available in sizes 1-1/2" through 84" diameter. Metal bellows can be made in most alloys. We use 321 stainless steel as a standard due to its excellent forming properties and high temperature properties. Other common alloys stocked at Black Flex we include 316 and 304 stainless steel. An expansion joint is a device used to allow movement in a piping system while containing pressure and the medium running through it. Frequently, thermal growth, equipment movement, vibration or pressure pulsation can cause movement in a piping system. When flexibility for this movement cannot be designed into the piping system itself, an expansion joint is the ideal solution.

PRINCIPAL USE
1. Absorption of thermal expansion or contraction of straight pipe runs where proper anchoring and guiding are feasible.
2. Addition of flexibility in short complex piping on machinery and vessels.
3. Isolation of mechanical vibration from piping and Ducting.
4. Sealing of piping penetrations in bulkheads of contaminant vessels, heat exchangers and ships.
5. Pressure operated control systems to absorb vibrations.

APPLICATION IN INDUSTRIES
1. Diesel engine construction: For exhaust lines of large engines to absorb mechanical vibrations and thermal expansions.
