Purpose

The СПГ gas flow stabilizer is designed to damp the flow swirls and fluctuations and to reduce the straight portions in front of and behind the СГ16-МТ, СГ16МТ-Р gas meter and is mounted directly in front of the meter.

When СПГ is used, an additional straight portion in front of and behind the meter is not required.
СПГ has a pipe connection with the G-1/2-B thread for connection of devices measuring pressure losses on the СГ meter.

Designation for requisitioning

When ordering it is necessary to specify the name of device, nominal bore value DN and the ambient air limiting reduced temperature – 30 (for a temperature of minus 30ºC) or 40 (for a temperature of minus 40ºC).

Example

Gas flow stabilizer СПГ for DN 50 designed for operation at a temperature of minus 40ºC: СПГ50-40

Warranty period: 24 months from the date of putting into service.

Service life: 12 years .
