The three plates are produced according to the ISO2531 standard, with a pressure of PN16 and made of ductile iron, which has good ductility and toughness.
The lining of the three plates and three connections is made of cement mortar and Portland cement, and the outside is coated with metallic zinc and asphalt paint.
The three plates and three connections are manufactured using the lost foam process, with a short production cycle and high dimensional accuracy. They are lined with cement, sprayed with zinc and asphalt paint, and have a long service life.
Main technical parameters of the three disks:
Material: nodular cast iron GGG-50450-12, etc
