An example of the type codes in the ordered specification:
T-socket with a ball valve for water dumping, outer diameter of the main pipe 426 mm, with thickness of pipe wall 7 mm and nominal diameter of the ball valve for water dumping 32 mm, with isolation of type 1 from polyurethane foam, in polyethylene (galvanized) casing:
T-socket with ball valve for water dumping St426*7-32-1-PUF-PEM
T-socket with ball valve for water dumping St273*7-32-PUF-GalM
Notes:
The nominal diameter of the ball valve for water dumping and also the height H can be set by the project.
