QUESTIONNAIRE

The field of application
Pressure reduction block PGB-13V-2-0.6-OG-U1-SG is assigned for purification from contamination and fiscal registration of volume consumption and natural gas pressure reduction from high to average and low values according to state standard GOST 5542. The unit automatically maintains the pressure in required range and switches the gas supply off in the event the pressure rises or falls beyond acceptable levels. The unit is used in gas distribution and consumption systems.
Main technical characteristics
1.2.1 Block is assigned for open-air operating in macroclimate regions with temperate climate in U-type construction and placement category 1 according to GOST 15150.
1.2.2 Estimated snow load is 120 kgforce/m2 corresponds requirments of II territory region, and wind load 38 kgforce/m2 – II territory region according to SNiP 2.01.07-85.
