Pipelines
Steel technological pipelines type TT are used for hydraulic and pneumatic transport of various materials and fluid in industrial facilities, including hazardous production facilities.
Pipelines can be of different types depending on their purposes:
НВ – delivery-suction pipeline;
Н – delivery pipeline;
В – suction pipeline;
Б – free-flow pipeline (return pipeline).
Pipelines can be of different types depending on transported fluid:
М – pipelines w/o internal protection to transport non-aggressive and mildly aggressive fluid;
С – pipelines w/o internal protection to transport mildly aggressive fluid;
А – pipelines w/o internal protection to transport highly aggressive fluid;
АА – pipelines with inner chemically and wear-resistant protection to transport abrasive and aggressive fluid, including powders and fine-grained bulk solids.
