thermal and mechanical alterations, sometimes, can not be absorbed in a pipe system; these should be compensated in order not to damege the installation. Where these are not taken into account, an overload can occur in the pipe system which, in extreme cases, can cause deformation, destruction or failure of the plant. Our expansion joints offer the optimum solution and are the most effective form of absorbing contraction, expansion and vibration in pipework system. The place of use and the type of movemet should be explained during the design ohase in order to choose a standard catalogued compensator.
TYPE OF METAL BELLOW EXPANSION JOINTS:
annularly corrugated metal bellows, formed from welded tubes; designed and manufactured fully according with EJMA standards and in conformity with the pressure and temperature ratings. Bellows and internal sleeves (liners) made of stainless steel, end connections either in stainless steel or carbo steel; other materials on request. Connections: fixed or floating flanges, male or female threaded ends, welding ends. Nominal diameters: from DN25 (1") up to DN 2600(104"). Pressure ratings: up to max 64 bar. Temperature ranges: from -196C degrees up to +1050C degreees, depending on the materials. Rating PN25: designed and manufactured to compensate at least 1000 full cycles at rated pressure and movements,
