Tanks for CHP-plants, NPGS and HPP

Description

Tanks and containers for CHP-plants, NPGS and HPP are designed to store process waters and chemicals used for chemical water treatment and other processes.

The Saratov Resevoir Plant produces three designs of the tanks:

Tanks for CHP-plants, NPGS and HPP production

Tanks for CHP-plants, NPGS and HPP are manufactured on the basis of ОСТ 34-42-566-82 "Tanks and containers for CHP-plants, NPGS and HPP made of carbon steel up to 1000 m3. Technical specification".*

Due to severe operating conditions, the tank body is made of carbon, alloy or stainless steel with a thickness of 4-12 mm (for carbon and alloy) and 4-10 mm (for stainless). If anti-corrosion treatment of the inner surface is not applicable, the shell thickness is calculated with corrosion allowance at the rate of 1 mm for 10 years of operation.

If necessary, heat insulation is equipped with a design load of up to 0.00045 MPa.

Fittings and nozzles are disposed on the shell and the bottoms for processing medium supply and delivery, for processing equipment installation (safety valve, level gauge, level alarm, instrumentation and control equipment, etc.). The equipment configuration is designed in accordance with the customer's requirements.

As well as the tanks of large volumes may be provided with a ladder and maintenance platform.

When designing, the space between the liquid surface and the shell (As) is provided, which must necessarily remain unfilled. It is necessary to prevent hydrodynamic impact. There are also strict requirements for the perceived ccontour pressure of the bottoms on the foundation (qmax). (see table below)

Volume, m3 Interval As, mm Pressure qmax, t/m
up to 100 300 2.0
100 430 2.42
160 450 2.9
250 510 2.3
400 550 3.3
630 600 4.3
1000 650 6.0

Rectangular tanks for CHP-plants, NPGS and HPP

Rectangular tanks are produced up to 2.5 m3 and are designed for indoor installation only.

Horizontal cylindrical tanks for CHP-plants, NPGS and HPP

Horizontal tanks are manufactured with a volume of 2-100 m3 with the possibility of outdoor installation, taking into account the wind load.

Tanks up to 75 m3 inclusive may be used as deaerator vessel and operated under pressure up to 0.02 MPa.
