The pipeline heater is an electric heating device that is installed in a cylindrical heat-preserving container with a heating tube to heat gas and liquid. The pipeline heater has the characteristics of fast heating speed, good heat preservation performance and high heating temperature.

The pipeline heater consists of two parts: the body and the control system. The heating element is made of stainless steel pipe as a protective sleeve, high temperature resistance alloy wire, crystalline magnesium oxide powder, formed by a compression process. The control part adopts advanced digital circuits, integrated circuit triggers, high back-pressure thyristors, etc. to form an adjustable temperature measurement and constant temperature system to ensure the normal operation of the electric heater.

There are two types of pipe heaters:

1. The gas pipeline heater is usually used to heat air, nitrogen and other gases, and can heat the gas to the required temperature in a short time.

2. Liquid pipeline heaters are usually used to heat water, oil, solution and other fluids to ensure that the outlet temperature reaches the required temperature of the process.

Principle of pipeline heater:

Features of pipeline heater:

1. The pipe heater adopts a stainless steel cylinder, which is small in size, small in area, easy to move, and has strong corrosion resistance. A thickened insulation layer is used between the stainless steel liner and the stainless steel shell to minimize temperature loss. Maintain temperature and save power. To

2. The main parts of the high-quality heating element (stainless steel electric heating tube) use imported materials, and the processing process also uses advanced production equipment and technology, with different voltages to achieve the highest performance. Its insulation, pressure resistance, and moisture resistance are all higher than national standards, and it is safe and reliable to use. To

3. Reasonable design of medium flow direction, uniform heating, no high and low temperature dead angle, high thermal efficiency. To

4. The pipeline heater is equipped with a thermostat of a well-known domestic brand, and the user can freely set the temperature. All are equipped with overheating protectors to control temperature and water shortage and overtemperature protection to avoid damage to heating elements and systems.

Pipeline heater structure type:

Pipeline heaters are divided into horizontal and vertical types, with the same working principle.

1. The vertical pipeline heater occupies a small area but requires height, and the horizontal type occupies a large area but the height is not required.

2. The materials of vertical and horizontal pipeline heaters are: carbon steel, stainless steel SUS304, stainless steel SUS316L, stainless steel 310S, etc. Choose suitable materials according to different heating process requirements.

3. The pipeline heater adopts flange-type electric pipe heating, and is equipped with a professionally designed deflector to ensure that the electric heating pipe heats evenly and the heating medium fully absorbs heat.

4. For high temperature requirements (the temperature of the outlet is greater than 600 degrees), the heat-resistant stainless steel 310S electric radiation heating tube is used for heating, and the temperature of the outlet can reach 800°C.

Pipeline heater application:

It is widely used in many scientific research and production laboratories such as aerospace, weapons industry, chemical industry and universities. It is especially suitable for the test of automatic temperature control and large flow high temperature combined system and accessories. The heating medium of the product is non-conductive, non-combustible, non-explosive, non-chemically corrosive, non-polluting, safe and reliable, and the heated space heats up quickly (controllable).
