Metallic Expansion Joints
WahlcoMetroflex is a leader in the design and manufacture of thin-walled, high performance convoluted metallic bellows expansion joints in round and rectangular configurations. In addition to design expertise of the expansion joint itself, the company’s application engineering capability allows WahlcoMetroflex to apply the joints in the piping/ducting systems to properly accommodate the movements caused by thermal growth, pressure contraction, machine vibration, seismic disturbances and installation irregularities.
WahlcoMetroflex Metallic Expansion Joints are designed to operate under the most severe temperatures and pressures: temperatures to 2000F/1093C and pressures to over 1000 PSIG/69 bar. As a fully qualified ASME code fabricator, WahlcoMetroflex is able to design and manufacture expansion joints in accordance with the ASME Boiler and Pressure Vessel Code.
Round metal bellows can be manufactured in diameters ranging from 4″ to 25’. Bellows can be designed to carry numerous types of media including steam, emission gases, water, acids, alkalis and hydrocarbons.
WahlcoMetroflex has manufacturing expertise in all relevant metals including stainless steels, high nickel alloys, titanium and aluminum. WahlcoMetroflex sits on the technical committee for EJMA, (The Expansion Joint Manufacturers Association).
