EXPLOSION PROTECTION


Flanged pipework was tested in the following configuration up to 3 bar over-pressure: Pipes


Segments 5°to 45° Bends 30° to 90° T-pieces


Forks 30° and 45° Cone pieces


Symmetrical forks 60° Symmetrical forks 90°


2 mm thick up to DN 800 mm 2 mm thick up to DN 800 mm 2 mm thick up to DN 800 mm


2 mm thick up to DN 500 mm, 3 mm thick up to DN 800 mm 2 mm thick up to DN 500 mm, 3 mm thick up to DN 630 mm 2 mm thick up to DN 630 mm, 3 mm thick up to DN 800 mm 2 mm thick up to DN 500 mm, 3 mm thick up to DN 800 mm 3 mm thick up to DN 630 mm


• For shock explosion proof pipe connections, bolt quality 8.8 is required • Bolt torque: M 10 = 40 Nm, M 12 = 60 Nm


Cleaning pipes are not available in a shock explosion proof version. Alternatively, inspection pipes (diameter of opening 115 mm) up to DN 630 mm pipe diameter can be delivered in a special version.
