high temperatureHigh pressure pipeThe furnace is mainly used in metallurgy, glass, heat treatment, lithium battery, positive and negative materials, new energy, abrasive and other industries. It is a professional equipment for measuring materials under certain temperature conditions. The furnace has simple structure, convenient operation, easy control and continuous production.

The high-temperature and high-pressure tube furnace is a new type of high-efficiency and energy-saving electric furnace developed by advanced technology. Tube furnace has a single tube, double tube, horizontal, can be opened, vertical, single temperature zone, double temperature zone, three temperature zone and other furnace type. Mainly used in universities, research institutes, industrial and mining enterprises of the experiment and small batch production. It has the advantages of safe and reliable, simple operation, high temperature control precision, good heat preservation effect, large temperature range, high furnace temperature uniformity, many temperature zones, optional atmosphere, vacuum furnace type, etc.

Single set point or 30 segment programmable controller can be selected. Energy-saving ceramic fiber material and double-layer structure can reduce the surface temperature to normal temperature. The average temperature zone is long, the operation is simple, the seal is reliable, and the comprehensive performance index is high, reaching the domestic level. Furnace tube can choose heat-resistant steel, quartz glass, ceramic tube and other materials.

8. Can be combined with multiple furnaces for mass production.

Disadvantages of high temperature and high pressure tube furnace:

(1) The applicability of heavy raw materials has certain restrictions

In the cracking of heavy raw materials, because the heavy raw materials are easy to coke, it is necessary to shorten the operation cycle, reduce the cracking depth, and often appear light coke, which not only shortens the effective production time of the year, but also affects the service life of the cracking furnace and furnace tube. Due to the reduction of cracking depth, the utilization rate of raw materials is not high, the number of low-value products such as heavy raw oil is large, and the cost of public works also increases.

(2) According to the process requirements of high temperature, short residence time and low hydrocarbon partial pressure, the surface thermal strength of the furnace tube will inevitably increase, which requires oil-resistant high-temperature alloy pipe and cast pipe technology.

Use SuperHigh pressure pipePrecautions and safety measures for the use of high-pressure pipes, and precautions for the use of ultra-high-pressure pipes are as follows:

1. It is important that the choice of rubber hose must be fair.

2. Correct end connection: Nut connection is widely used because of its convenience and low cost. However, in the case of large vibration, the problem of loosening of the nut should be fully considered. In this case, a flange connection can be considered. If the impact pressure of the system is higher than the specified working pressure of the high-pressure hose, it will not only reduce the service life of the high-pressure hose, but also cause personal and equipment accidents.

3. Fluid compatibility: The fluid in the high-pressure hose should meet the name in the "use" of the product sample. In addition, the service life and safety of the pipeline cannot be guaranteed.

4. Temperature: The fluid temperature and ambient temperature, whether undisturbed or instantaneous, must not exceed the temperature tolerance limit of the high-pressure hose, and the temperature should be lower or higher than the recommended temperature of the high-pressure hose.

5. Pressure: The working pressure specified by the high-pressure hose shall not be lower than the large system pressure under normal conditions.
