Example of a symbol in an order specification:
Pipeline end element with an outside diameter of 273 mm, a wall thickness of 7 mm, with
Type 1 insulation made of polyurethane foam in a polyethylene (galvanized) shell, with a metal insulation plug 650 (200) mm long
Pipeline end element St273x7-1-PPU-PE-650 with MZI
Pipeline end element St273x7-PPU-OC-200 with MZI
Distance from the end of the pipe to the metal insulation plug 70 mm – for diameters up to and including 219 mm, 110 mm – for pipes of other diameters.
