Industrial electrical heating of pipelines
The main objective of heating of pipelines is maintenance of the set temperature of the transported product, and in certain cases and its heating not to allow freezing, change of structure products and failure of all production system.
Application for free calculation
With fall of temperature sharp reduction in the rate of the movement of liquid on pipes or a full stop as a result of formation of plugs is observed, which leads loss of capacities of production. It is possible to successfully resolve this matter, having established the heating cable for the oil pipeline.
The main branches of industrial heating are:
Oil and gas branch
- Chemical branch
- Objects of civil engineering
- Transport branch
The main feature of such equipment is the possibility of adjustment of temperature of heating in the automatic mode. At selection of the corresponding cable it is necessary to take the next moments into account:
- material of pipes production;
- transported liquid;
- required power in working mode and at rest.
Heating of pipelines with the heating cable significantly simplifies process of laying and thermal insulation of pipes. At installation of the equipment there is no need to stack pipes lower than the level of frost penetration in the earth.For reduction of heatlosses by insulating materials to the minimum level it is required to make qualitative thermal insulation of the pipeline. материалами.
The heating cable for oil pipelines allows to effectively solve such problems:
Protection against freezing;
- Protection against formation of condensate;
- Maintenance of technological temperature;
- Heating of technological liquids.
When cooling the transported product (oil, gas, water, fuel, etc.) becomes more viscous or crystallizes, that leads to obstruction of the pipeline and, as a result, failure of the expensive equipment.
Various heating systems of pipelines are applied to prevent the increase in viscosity or freezing of the transported product, but the most effective one is the cable electrical heating.
Advantage of cable systems of an electrical heating is rather low cost of materials, ease of installation, resistance to corrosion, a possibility of powering from the general power supply system of an object and also existence of an automated control system, which precisely and on the set algorithm supports the chosen operating mode, is easily integrated into ACS of the top level and can be applied on branched pipelines of any complexity.
For selection of an optimal solution on the pipeline heating, initial data on the pipeline extent, system designation, temperature condition, thermal isolation and so forth are necessary.
By experience of heating, pipelines up to 400 m long should be heated with a self-regulating cable, which is a cable with the heating matrix with an opportunity to change heating temperature, depending on the set conditions of air temperature. In other words, depending on ambient temperature, for example, from -5 °C to -30 °C, the self-regulating cable maintains the necessary temperature, regulating this way thermal emission power and heats more or less, where needed.
Pipeline heating has a number of advantages:
Allows to reduce the cost of electric power;
- Allows to regulate section length on the place of installation (i.e. it can be cut off the necessary length);
- Has a possibility overlapping the cable.
For pipelines more than 400 m long an optimal solution on heating are single-core and three-core resistive heating cables of the RTS and LTS series. Such cable at the same time heats and feeds lines. It has a number of advantages, such as simplicity of design, low cost in comparison with self-regulating cables, but one disadvantage is the section of strictly set length and it should be considered at a system design stage. Such cables are great when temperature of maintenance is up to 260 °C.
In case when working temperature has to be up to 450 °C a cable in mineral isolation is used, capable to maintain high temperature loading, thanks to the cover.
