Vertical apparatus with elliptical bottoms and "jacket" (VEE)


Vertical apparatus with a "jacket" (VEE) are used in oil and gas and chemical industries. They are used both for storage of various liquids, and for the loading-unloading operations. A distinctive feature is the presence of a jacket that can perform a dual function: to heat or cool the stored product. This is necessary for viscous media or when the ambient temperature drops to the minimum when natural drainage is difficult.

The discharge of the working product occurs both by gravity and by compressed gases displacement (air, process or inert gas).

Operating condition of all-welded vertical vessels with elliptical bottoms and "jacket"

  • designed for tropical, temperate and cold climates
  • ambient temperature: -60°С ... +50°С
  • for storage and delivery: petroleum products, oils, petroleum lubricants, chemicals, food products, gases
  • pressure: 1 MPa
  • heat carrier pressure in "jacket": 0.6 MPaа
  • seismicity: up to 6 points
  • aboveground disposal only

Construction of vertical apparatus with elliptical bottoms and "jacket"

Apparatus VEE are all-welded vessels with elliptical bottoms. There is a so-called jacket for permanent or temporary heating or cooling of the stored liquid in the housing.

The vessels are mounted on leg- or lug-supports.

Manufacture of all-welded vertical apparatus with elliptical bottoms and "jacket"

The Saratov Reservoir Plant has the necessary Certificates of Conformity for the manufacture of apparatus and vessels for various purposes.

Vessels VEE with a "jacket" of the following nominal volumes are manufactured at SARRZ: 1 m3; 2 m3; 3.2 m3; 5 m3; 6.3 m3; 10 m3.

The apparatus are fabricated of different steel grades depending on the operating conditions and customer requirements:

  • carbon steel
  • acid-resistant steel 12Х18Н10Т, 10Х17Н13М2Т, 10Х17Н13М3Т, 06ХН28МDТ (EI 943)
  • low-alloy steel 09G2S, 16GS, 10G2

Our plant produces VEE apparatus with a "jacket" in accordance with accepted state standards:

  • OST 26-291-94 "Vessels and welded steel vessels. General specifications"
  • GOST 9931-85 "Cylindrical steel welded vessels and apparatus housings"
  • GOST R 52857-2007 "Vessels and Apparatus. Norms and methods of strength calculation. General requirements"
