Pressure tanks

Description

Pressure technological tanks are used for storage and delivery of water, process fluids and chemicals under pressure up to 2.5 MPa in manufacturing process at enterprises of various industries (chemical, housing and utilities infrastructure, energy, petrochemical, etc.).

Pressure tanks manufacture at SARRZ

We produce technological pressure tanks up to 32 m3 in vertical and horizontal design for aboveground and underground installing.

Carbon, alloyed and stainless steel with thickness of sheet metal of 4-12 mm and 3-10 mm respectively are used. As the tanks are used with aggressive media and liquids with high corrosion properties, the thickness of the shells and the bottoms is calculated with the corrosion allowance.

Pressure tanks design

Pressure tanks are manufactured in vertical and horizontal versions depending on operating specifications at the facility and customer's requirements. At site, the tanks are mounted on saddle or foot supports. When placed underground, horizontal tanks have supports or lodgements.

Vertical pressure tank Horizontal pressure tank
Vertical pressure tank Horizontal pressure tank

The body has a welded cylindrical design with elliptical, conical or torospherical bottoms that can withstand high pressure operation.

Inlet and outlet pipes are provided for inlet and outlet of the processing liquids. The standard design also includes fittings for drainage and a safety valve.

Additionally, at the customer's request pressure tanks are completed with:

  • level indicator (quartz tube)
  • breathing nozzle
  • surge line nozzle
  • instrumentation and control nozzle
  • recycle nozzle
  • assembly cover
Pressure tank of vertical design

Equipment configuration, its layout and diameter of the fittings are calculated based on the product specifications.

If necessary, the tank may be equipped with protective wall, thay functions as a steam jacket, to keep the temperature with the design limits To heat or cool the liquids, the tanks are equipped with an internal or external heat exchanger - a pipe coil or heating elements.
