Advantages of the design:
The geometry of the flow part is specially designed to eliminate cavitation and increased noise. The cranes have a high throughput and a wide range of regulation, ensuring minimal pressure loss. Self-cleaning of the running part of the cranes with the working medium in the open position. Seal in the metal-to-metal gate. Wear-resistant coating of surfaces with tungsten carbide.
Appointment:
Maintaining the necessary parameters of the working medium (pressure, flow rate) on the specified sections of the pipeline.
Working environments:
— commercial oil at temperatures from -15 °C to +80 °C;
— petroleum products at temperatures from -35 ° C to +60 ° C.
Climatic version:
«U» (areas with a temperate climate and ambient temperature from -40 °C to +40 ° C;
«HL» (areas with a cold climate and ambient temperature from -60 °C to +40 ° C;
«UKHL» (areas with temperate and cold climate and ambient temperature from -60 °C to +40 ° C;
Crane placement category — 1 according to GOST 15150.
Earthquake resistance:
Execution according to the 12-point scale of seismic intensity MSK-64:
— non-seismic resistant (for areas with seismicity up to 6 points inclusive);
— earthquake-resistant (for areas with seismicity from 6 points to 9 points inclusive);
— increased seismic resistance (for areas with seismicity from 9 points to 10 points inclusive).
Connection to the pipeline:
The installation position of the cranes is on a horizontal pipeline with a vertical arrangement of the crane spindle with a deviation from the horizontal axis up to 4 ° in a vertical plane perpendicular to the axis of the pipeline.
Connection to the pipeline:
— flanged (version F) according to GOST 33259;
— for welding.
To install cranes on a pipeline having a nominal diameter greater than the required nominal diameter of the crane, concentric transitions made in accordance with the requirements of the regulatory documents of PJSC Transneft are used.
