Collar flanges are classified by diameter and pressure. Depending on the pressure of gases and liquids in the pipeline system, the number of holes in the bolts of the flange fittings varies.
The diameter of the flange connections is from 15 to 2500 mm, the nominal pressure is from PN 16 to PN 160 Kgs/cm.
Different in type and diameter, flanges in terms of technical characteristics fully comply with current standards.
Documents regulating their production:
GOST 12820−80;
GOST 12821−80;
GOST 12822−80.
Flange fittings are manufactured using the latest technologies from high-quality steel, widely used in the oil, gas and chemical industries.
High-quality steels are used for the manufacture of flanges:
grades St3sp GOST380-94;
grade st20 GOST1050-88;
grade 15X5M GOST 4543-71;
grade 09G2S GOST19281-89;
grade 10G2 GOST4543-71
