High-pressure piping systems with heat insulation and electric heating

High-pressure piping systems with heat insulation and electric heating represent polymer-armored flexible multilayer piping intended for transportation and pumping of aggressive media, oil, gas (including admixtures), chemical liquids under the temperatures from minus 60ºС to plus 60ºС and operating pressure of up to 180 аtm.  They are used for laying on land and can sustain both dynamic and static loads.

The high-pressure piping systems with heat insulation and electric heating are specifically designed for low temperatures. The specific feature is presence of the heat insulation and electric heating layers. The electric heating layer makes it possible to transport fluids over the considerable distance without any notable temperature drop and to prevent fluid freezing in case of the pipeline shutdown.

The structure of pipes may vary depending on the operation conditions and necessity to perform specified functions. The internal diameter may vary from 30 to 140 mm considering the operation conditions. Operating pressure is from 40 to 180 atm.

To tie-in the segments the fitting gear is used. To control the process of heating control stations are employed.

Patent protection of the design on the territory of Russia is ensured.

High-pressure piping systems are manufactured in accordance with the technical specifications of the manufacturer basing on the TU compliance certificate.

High-pressure piping systems represent polymer-armored flexible multilayer piping.

Well have the following structure:

  • Core – polymeric layer which ensures undamaged condition of the transported fluid. The core is made by continuous extrusion from the compositions based on the low pressure polyethylene.

  • Reinforcing layer – structural component comprising several layers of metal tape wrapped over in the opposite directions which enhances resistance of the flexible pipe to internal and external pressure and to mechanical collapse load.
  • Anti-wear layer – non-metal layer in the form of tape wrapping intended for reduction of wear between the layers.

  • Electric heating layer – structural component, comprising segments with heating and signal conductors, intended for heat conservation of the transported fluid.  
  • Heat insulation layer – polymeric layer made of foamed polyethylene, which ensures heat conservation of the transported fluid.
  • Outer sheath – polymeric layer intended for protection of reinforcing elements from corrosion, abrasive and mechanical damage and for retaining the elements in the position predetermined by shaping. The outer sheath is made by continuous extrusion from the compositions based on the low pressure polyethylene.

Inner diameter 30 – 140 mm (1,5”– 6”)
Operating temperature range -60°С … +60°С
Operating pressure 40 – 180 atm
Maximum end-to-end dimension (for diameter 50 mm) 1 400 m
Handled media oil, gas, water, abrasives, aggressive media

High-pressure piping systems as compared to metal piping have the following advantages: larger end-to-end dimensions and consequently reduction of the installation time, provision for underwater, underground and aboveground laying. The components being in contact with the fluids are made of polymers and demonstrate high corrosion resistance.

The high-pressure piping systems may be placed into the narrow trench (the trench width is by 40% less than for steel piping). Due to reduction of the volume of welding works, works on protection of the welding joints and insulation coating, installation, laying and putting into operation is eight times as fast as in the case with the steel piping.

Irrespective of the fluid corrosive power the service life of the high-pressure piping systems is longer than for steel piping.

Heat insulation and electric heating layers provide for the required temperature of the fluid in the course of transportation and prevent its freezing in case of shutdown.

On the diagram you can see the fluid temperature drop along the pipeline with the breakdown by the type of piping.

The following data were used for building up the diagram:

  • Pipeline inner diameter - 80 mm;
  • Initial temperature of flow - plus 20 °С;
  • Ambient temperature - minus 20 °С;
  • Fluid flow rate - 20 м3/hour; pipeline length - 1000 m.

As you can see from the diagram the high-pressure piping system ensures maintaining of the same level of the fluid temperature along the pipeline.

Depending on the operation conditions it is possible to make the reinforcing layer from the polymer tapes, preserving the maximum values of the internal operating pressure, which provides for chemical resistance of the pipe to all aggressive media in case of production and transportation of gas and oil.

Five-layer inner liner, comprising a barrier layer made from special material, ensures reduction and complete elimination of gas permeability in comparison to other pipes. Our competitors cannot boast of such opportunities. Due to reduction of gas permeability the barrier layer decreases corrosion of metal tapes or completely fixes the problem. The piping of this type is used for delivery of oil and gas with high content of СО2, H2S and CH2.

The barrier layer of 1 mm thick demonstrates same characteristics as the wall made of the low -pressure polyethylene of 10m thick.
