How to improve the thermal insulation of water pipes at the pier
After several tests, Dandong Port finally decided to use PP-R pipes for water pipes and a series of low-temperature self-regulating electric heating cables for electric heating.
Jan 31,2023
Dandong Port made a number of improvements to the Wharf Water Pipeline Isolation Project in 2006. The original cast iron water supply pipeline was replaced with a polypropylene pipe, and the polyurethane foam and electric heating method was replaced with the original mineral wool. Insulation., which not only prolongs the service life of the pipeline, but also increases the corrosion resistance, compression resistance and compression resistance.
Polyurethane foaming technology is rapidly replacing crude oil pipeline insulation measures to occupy the market due to its advantages: low thermal conductivity, low bulk density, high compressive strength, good overall connectivity and good water resistance; Accurate control, high reliability, long service life. beneficial for environmental protection, Saving insulation materials, simple and convenient design, small maintenance work and high efficiency. Can significantly reduce energy consumption and other advantages.
After several tests, Dandong Port finally decided to use PP-R pipes for water pipes and a series of low-temperature self-regulating electric heating cables for electric heating.
Low temperature self-regulating electric heating tapes are widely used in civil solar energy, geothermal heating, fire, petroleum, chemical, steel, electric power, environmental protection and other industrial enterprises for heating, heat preservation, anticoagulation and anti-freeze protection of pipelines and tanks. The heating cable is suitable for common areas, explosive zones and corrosion zones. After being used together with the explosion-proof power junction box, it is suitable for T6, T4 and T3 explosive gas mixtures in the first and second areas of the plant, which are not directly affected by external forces.

Electrical heating installation precautions
Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.
Which electric heating should be chosen for the main pipeline transport of heavy oil
Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.
Which electric heating cable should be considered for a 4 km pipeline
According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.
Application of outdoor electric heating cable in oil main pipelines with high paraffin content
Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.
What heating product to choose for main infusion pipelines
In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.
The role of leather tracer cables in the insulation of asphalt main pipelines
The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
