Heating of pipelines
Pipework heating in industry is most often required by industries that transport products via oil and gas pipelines, the food industry and the chemical industry. Violation of the temperature regime in such a situation is fraught not only with a temporary stoppage of work, but also with considerable monetary losses. They are caused by downtime, leaks resulting from compromised pipe integrity, fines for environmental damage if the product is toxic. Not all, but many problems can be avoided with pipework heating.
Industrial pipework heating is in demand in the oil and gas, chemical, transport, food, chemical and civil engineering sectors. It significantly reduces the risk of loss due to slow movement of fluid through pipes and helps to keep production efficiency high.
Heating of pipelines with heating cable is only realised in three cases:
- Freeze protection;
- Maintaining the process temperature;
- Warming up is an increase in temperature.
Let’s take a brief look at each of them.
Product freeze protection is necessary to eliminate the possibility of ice forming in the product or the product solidifying. This is characteristic of water or water-containing products. In industrial plants, frost protection systems are used when it is necessary to maintain the set temperature of a product (water, acids, alkalis) slightly above zero. Heating of pipelines with frost protection implies “temperature maintenance” not more than plus 10 degrees with heating cable power up to 30-40 W/m depending on the type and thickness of thermal insulation.
Process temperature maintenance is the setting of temperatures between 10 and 600 degrees Celsius in industrial electric heating systems, at a power of up to 98 W/m depending on the type and thickness of the thermal insulation. Usually high temperatures are maintained in pipelines for viscous products (fuel oil, bitumen, etc.), petroleum products (gas oil, diesel fuel, etc.) and chemical products (sulphuric acid, nitric acid, etc.).
Product heating is the raising of different types of products in pipework over a period of time, with cable power up to 120 W/m depending on the type of product being heated. The product can be heated in the tube from any temperature (even sub-zero temperatures) up to sufficiently high process temperatures. It is usually not practical to heat up the product with heating cables, either self-regulating or resistive, because the product is not heated with heating cables. product heating is usually characterised by the application of very high power per metre of pipe. But in many cases it is possible to solve the problem of temperature rise. The fact is that a cable heating system has a limited wattage per metre of heating cable and applying very high wattage on a pipe is problematic. There is an option to lay the heating cable spirally along the pipe or in multiple strands along the pipe, but usually even with this arrangement the power may not be sufficient.
For the correct selection of the electric pipe heating system you need to contact specialists who will make a thermal calculation and select a suitable heating cable with all the necessary components.
