Key features and benefits

• Available in a range of standard diameters (Ø approx. 125 mm, 200 mm, 250 mm, 300 mm and 400 mm) for quick selection.

• Round design makes it ideal for inspecting pipes, cylindrical vessels or weld seams that are located around the entire circumference.

• Transparent inspection glass and soft sealing strip ensure good visual observation (bubbles/leaks) during vacuum testing – which is standard procedure in MR Chemie's leak testing program.

• Compatible with MR Chemie's vacuum test equipment and test procedures, so the solution fits into existing inspection setups.

Technical specifications

• Valve with adapter (conical or standard) for connecting vacuum hose; the valve can be sealed at different angles.

• All models have a built-in vacuum gauge to ensure that the correct vacuum level is maintained during testing and to avoid misinterpretations.

Technical specifications

• Diameter selection: from DN 100 to DN 1600 – i.e. pipe diameters from approx. 114.3 mm up to approx. 1626 mm.

• Length: approx. 195 mm for DN 100, and length increases with diameter, up to approx. 730 mm for larger diameters.

• Butt weld only – the box covers the entire circumference of the weld.

Areas of application

• Leakage inspection of fully welded pipe joints (circumferential butt welds) in tanks, pipelines and cylinder structures.

• Applications where the weld is not accessible from both sides, but only the outside can be inspected.

• Laboratory and field use, where visual detection via bubble test requires good sealing and observation through glass.

• Industrial maintenance control – for example in pipe installations, flowing pressure vessels, tanks and ships, especially where leak control is safety or environmental critical.
