Steel welded reservoirs are designed for reception, storage, transportation and discharge of liquid and gaseous media, harmful, explosion- and/or fire-hazardous ones including, classified by GOST 12.1.007 and GOST 12.1.011 (except for the type ÂÊÏ apparatuses) with the density of not exceeding 1600 kg/m³ and temperature of -70°C to +200°C in the condition of single and multiple static loads with the number of load cycles of not more than 1000 for the entire operation period, in the regions of max. 6-magnitude seismicity.

Basic structural material depends on the temperature and represents: 

carbon steel ÑòÇñï, GOST 380; low-alloyed steel 08Ã2Ñ. 16ÃÑ, GOST 5520; stainless steel 08X22H6T, 12X18H10T, 10X17H13M2T, GOST 5632.

• horizontal with ellipsoidal heads, ÃÝÝ type, with volume capacity of 10 m³ and reference pressure of 0,6; 1,0 and 1,6 ÌÐà (6,10 and 16 kgf/cm²) (see foto);

• horizontal with ellipsoidal heads, ÃÝÝ1óðå, with tube bundle, volume capacity of 10m³ and reference pressure of 0,6 MPa (6 kgf/cm²). The tube bundle is intended for medium heating or cooling. The heat-transfer agent pressure does not exceed 0,6 MPa (6 kgf/cm²);

• vertical with ellipsoidal heads, ÂÝÝ type, volume capacity of 10m³ and reference pressure of 0,6, 1,0 and 1,6 ÌPà (6,10 and 16 kgf/cm²) (see foto);

• vertical with ellipsoidal heads, ÂÝÝ type, with jacket, volume capacity of 10 m³, reference pressure of 1,0 ÌÐà (10 kgf/cm²);

• vertical with conical bottom and flat top heads, ÂÊÏ type, volume capacity of 10 and 16 m³, designed for storage of liquid explosion- and fire-hazardous media (harmful media of 3 and 4 class of danger, GOST 12.1 007, including) of increased viscosity and having a sediment. In case need is arise to maintain the preset temperature condition, the reservoir is provided with a coil, in which heat-transfer agent pressure must not exceed 0,6 ÌÐà (6 kgf/cm²).
