The system of unpaved heating pipe is designed in such a way that it has a certain length, the functions of heating and transportation – “Composite soil heating pipe”. Since the collector is buried in the ground, low surface energy and a small roughness are formed on the inner wall, which prevents scaling and sedimentation of paraffin. In terms of heating functions and resistance to the deposition of salts, system requires almost no maintenance.
At the inlet and outlet of the unpaved heating pipe system, sensors for measuring internal temperature and internal pressure are installed. The temperature of the oil regulates the heating power so that the temperature of the oil is maintained at a certain temperature range (for example, about 50 degrees). By monitoring the pressure sensor in real time, can determine the point of clogging or accident
The control system also has a remote control function. If a failure or accident, engineers can remotely control the entire system. The control system heating pipe has the following functions:
Heating and heat insulation pipeline with long distance
Often there is a need to pump oil over long distances from one well to another. For this, a heating and heat insulation pipeline is provided. He allows to heat it to a predetermined temperature during the process of transporting crude oil
