Electric Pipeline Heater for Heavy Oil Heating

Short Description:

Electric pipeline heater is a highly efficient, reliable heating solution specifically designed for heavy oil transportation and storage systems. Heavy oil features high viscosity and low fluidity at low temperatures, which often causes pipeline blockages, reduced flow efficiency and even production shutdowns. Our electric pipeline heater directly heats heavy oil as it flows through the pipeline, maintaining a consistent operating temperature that keeps heavy oil fluid, ensures smooth transportation and reduces energy waste caused by pumping resistance.

Product Overview

Our electric pipeline heater is a highly efficient, reliable heating solution specifically designed for heavy oil transportation and storage systems. Heavy oil features high viscosity and low fluidity at low temperatures, which often causes pipeline blockages, reduced flow efficiency and even production shutdowns. Our electric pipeline heater directly heats heavy oil as it flows through the pipeline, maintaining a consistent operating temperature that keeps heavy oil fluid, ensures smooth transportation and reduces energy waste caused by pumping resistance. Compared with traditional steam heating systems, this electric heating solution eliminates the need for boiler equipment, steam pipelines and complex water treatment processes, featuring lower installation costs, smaller footprint, higher energy efficiency and more precise temperature control. It is suitable for heavy oil gathering pipelines, long-distance transmission pipelines, storage tank outlet pipelines and terminal loading pipelines in petroleum exploitation, refining, chemical engineering and road construction industries.

Working principle

The electric pipeline heater for heavy oil adopts an integrated tubular heating structure. High-quality electric heating elements are directly installed inside the pipeline section, which directly transfers heat to the flowing heavy oil through contact heating. The entire heating process is carried out in a fully enclosed pipeline, so there is almost no heat loss, and the thermal efficiency can reach more than 95%. The equipment is equipped with a high-precision intelligent temperature control system that can real-time detect the outlet temperature of heavy oil and automatically adjust the heating power to maintain the set temperature. For different pipeline diameters and heavy oil flow rates, we provide customized power configurations to ensure that the temperature rise meets production requirements without causing excessive energy consumption or oil quality deterioration caused by overheating.

1.Electricity conversion: external power source (usually industrial AC) is input into the heater control system.

2.Electric thermal conversion: Electric energy is converted into thermal energy through built-in electric heating elements.

3.Control cabinet: Real time monitoring of crude oil temperature through temperature sensors installed on pipelines (such as PT100 thermistor or K type thermocouple), and feedback of signals to the temperature controller. The controller intelligently adjusts the power supplied to the electric heating element based on the set target temperature (usually achieved through thyristor, solid-state relay, etc. for on-off or power regulation control), achieving precise and stable temperature maintenance.

Working condition application overview

1) Overview of sewage heating pipeline electric heater

The electric heater is a kind of equipment which is mainly used for sewage heating in sewage treatment project. The electric heater converts electrical energy into heat energy to realize the heating effect of the sewage heating pipe and improve the efficiency and quality of the sewage treatment process.

2) Working principle of electric heater of sewage heating pipeline

The working principle of the electric heater in the sewage heating pipeline can be divided into two parts: electric energy conversion and heat transfer.

1. Electric energy conversion

After the resistance wire in the electric heater is connected to the power supply, the current through the resistance wire will produce energy loss, which is converted into heat energy, heating the heater itself. The temperature of the heater surface increases with the increase of the current, and eventually the heat energy of the heater surface is transmitted to the sewage pipe that needs to be heated.

2. Heat conduction

The electric heater transfers heat energy from the surface of the heater to the surface of the pipe, and then gradually transfers it along the wall of the pipe to the sewage in the pipe. The process of heat conduction can be described by the heat conduction equation, and its main influencing factors include pipe material, pipe wall thickness, thermal conductivity of heat transfer medium, etc.

3) Summary

The electric heater converts electrical energy into heat energy to realize the heating effect of the sewage heating pipeline. Its working principle includes two parts: electric energy conversion and thermal heat transfer, of which thermal heat transfer has many influencing factors. In practical applications, the appropriate electric heater should be selected according to the actual situation of the heating pipeline, and reasonable maintenance should be carried out.

Product Features

1. 1. Efficient and Uniform Heating
  
  The heating elements are arranged reasonably in the pipeline to ensure that heavy oil can fully exchange heat during the flow process, avoiding local overheating or uneven temperature distribution. This uniform heating method effectively maintains the original properties of heavy oil and prevents coking and deterioration caused by local high temperature.
  
  2. Safe and Reliable Operation
  
  Multiple safety protection measures are built into the equipment, including over-temperature protection, over-current protection, leakage protection and pressure-resistant housing. The outer wall of the heater adopts high-performance thermal insulation material, which not only reduces heat loss but also ensures the surface temperature is within the safe range, avoiding the risk of scalding to operators. All electrical components meet international explosion-proof standards, can be used in flammable and explosive hazardous environments such as oil fields and refineries, and comply with Class I Divison 2 explosion-proof requirements.
  
  3. Intelligent Automatic Control
  
  The equipped intelligent temperature control system supports remote monitoring and adjustment, can be connected to the central control system of the production site, and realizes unattended operation. Users can set the required heating temperature according to different types of heavy oil and ambient temperature changes, the system will automatically maintain the temperature, no need for manual adjustment on a daily basis. It also supports data recording and fault alarm functions, which is convenient for equipment management and maintenance.
  
  4. Long Service Life and Low Maintenance
  
  The heating elements are made of high-temperature resistant and corrosion-resistant alloy materials, which can work stably in heavy oil medium for a long time. The fully welded sealing structure ensures no leakage, and regular inspection only needs to check the electrical control part, no need for frequent replacement of vulnerable parts, effectively reducing the overall operating cost.
  
  5. Flexible Customization
  
  We can provide customized design and manufacturing according to the user's on-site pipeline parameters, including different pipeline diameters from DN50 to DN1200, different power ranges from 10kW to 1000kW, and different pressure ratings from 1.0MPa to 10.0MPa, which can perfectly match the existing pipeline system of the user and reduce the difficulty of on-site installation and transformation.
