Debut ASME seal for the steam test bench
LESER has extended the scope of its test bench approvals to include the steam test bench.
To assure the quality of its products, LESER has been operating safety valve test benches of its own since the 1950s. Developments and certification checks use air, water or steam as media. Since 1994, the air and water test lab at the Hamburg site has been ASME-certified, allowing the company to perform safety valve certification tests to ASME BPVC Sec. VIII on its own test benches.
In December 2024, the scope of the approval was extended to include the LESER steam test bench. Since 2001, the steam test bench has been located at the Rugenberger Damm waste recycling plant and is directly connected to the steam pipeline system.
The process heat is used to generate electricity and heat. For pressure testing, the plant can deliver a steam volume of up to 15,000 kg/h at pressures of 45 bar and a temperature of up to 425 °C.
LESER is currently the only manufacturer worldwide with a steam test bench that is ASME-approved.
