Piping suction and pressure-suction are designed for suction and injection of various liquids and slurries in the temperature range from -40 to +50 ° C. Suction pipelines operate under vacuum to 600 mm Hg. Suction, pressure-up to 10 kgf / cm2 and discharge to 600 mm Hg. They are produced in diameter up to 530 mm and length up to 7300 mm with flanges or cuffs.

The presence of spacer rings and double helices in the design of the pipelines eliminates the loss of cylindrical shape during bending and discharging. (f 1, f 2)
