Leak-off testing of heating systems

SOTA-20-20 Flow: 200 m³/hour
Pressure: 200 m

Task

Leak-off testing of heating mains before the start of heating season.

Region Omsk Industry Housing and communal services

Solution

SOTA-20-20

Design features:

Load-bearing hood that provides upper overload without the use of crossheads
Use of shutter doors for convenience of operation and maintenance
Application of additional systems for preventing overheating, heat takeoff, and cooling of bearing supports when the pump is in dry run.
Wi Fi data exchange (online) while leak-off testing (using a removable industrial antenna)
Certified hardware and software unit
The software installed on the laptop allows you to build graphs and reports with accurate recording of all parameters of hydro-testing process in time

Calculate my project

The customer needed to check the tightness and integrity of the heating mains in a new district before the start of the heating season.

Since the tests had to be carried out locally, without disconnecting a large section of heating networks, the solution needed to be mobile and fully automated.
Our company solved the task with help of the automated station
Water pressure test of SOTA 20-20 pipelines.

SOTA Station provides:

creating, retaining and relieving pressure in heating networks with a set speed and frequency
detecting of pipeline break by the specified flow parameters
emergency shutdown of the installation when detecting of pipeline break or maintaining the necessary flow rate to search for the pipe break
water intake from the source using a special feeding device (optional, necessary if there is no backwater at the inlet)

The SOTA use makes it possible:

conducting planned hydraulic tests on small sections of heating networks;
carrying out unscheduled water pressure testing of heating networks in new housing areas;
reducing the required time for performing annual pressure testing operations;
improving the safety of pressure testing operations for personnel and a city’s infrastructure;
saving the service life of stationary stations;
reducing the risk of pipeline accidents;
Reducing periods of turning off hot water;
disabling a smaller number of heat consumers.

Advantages of a controller-based system:

Convenient graphical operator panel
Wi-Fi access to controller and archive data.
Maintaining an archive on a specialized memory card
Access to the archive via a browser from a PC
Real-time test monitoring program on a PC
Control of the water pressure testing in both automatic and manual modes
Automatic detection of emergencies and their handling.
Duplicate emergency stop functions using a mechanical button and remotely using a PC
Duplicate the main controls using mechanical buttons, toggle switches, switches and indicators.
