Polymer armoured pipelines for main lines and flowlines
Description
The company OOO “Pskovgeokabel” designed high pressure flowlines. It is possible to increase operational characteristics of the pipelines using armouring technique. High strength materials make armouring. The base pipe can be produced of polymer resistant to hydrocarbons, and in this case, it is possible to pump through oil products and gas. The pipelined produced with such technology have much better limits for breaking force, inside pressure and they are more stable by crashing loads.
The important issue by operation of the pipelines is the increase of thermal isolation. Most of our country is in the area of moderate and cold climate, and matter of keeping temperature of pumped fluid is very important.
One of the most effective way to decrease factor of heat transfer is use of complimentary intermediate thermal insulation from foamed polyethylene. Insulation layer 3-6 mm decreases losses of temperature to 30 -60 %. However, use of complimentary insulation often does not solve the problem of cooling transported fluid. Cooling the fluid can lead to thickening and even to its full freezing. Heated pipeline can be used for operation in these conditions. Heating conductors are set in the pipe wall under thermal insulating sheath that significantly increase effectiveness of the heating. By this design of the pipeline, heating power 10 W/m is enough to compensate heat losses and keep operation of the pipeline even by -60 oC.
