Production-oriented users in the food industry and research on various scientific research and experimental projects,

Used for hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation,

Containers for process operations such as hydrocarbonization, polymerization, condensation, heating and blending, and isothermal reactions.

Features of the stainless steel reactor: The inner surface is mirror-polished to ensure there are no sanitary dead spots.

The fully enclosed design ensures that the material remains sterile at all times; the outer surface can be optionally sandblasted or frosted.

Cold-rolled, natural-color matte finish; heating and cooling: heating methods available include steam, electric heating, and thermal oil.

To meet the process requirements of various working environments, including resistance to acids, alkalis, high temperatures, wear and corrosion.

By pressure class: Low-pressure (code L) vessels—0.1 MPa ≤ p < 1.6 MPa;

Medium-pressure (code M) vessels: 1.6 MPa ≤ p < 10.0 MPa; High-pressure (code H)

Pressure vessels: 10 MPa ≤ p < 100 MPa; ultra-high-pressure (code U) vessels: p ≥ 100 MPa.

Classified by the role of the vessel in production: Reaction pressure vessels (code R):

Used to carry out physical and chemical reactions of the medium. Heat-exchange pressure vessel (code E):

Used for heat exchange with the medium. Separation pressure vessel (code S):

Used for fluid pressure balance buffering and gas purification separation to complete the medium.

Storage pressure vessels (code C, with spherical tanks coded B): used for storing and containing gases and liquids.

Media such as liquefied gases. According to safety technical supervision and management, they are classified into three categories: Class I pressure vessels;

Class II pressure vessels; Class III pressure vessels. Classified by installation method:

Stationary pressure vessels; mobile pressure vessels.

When using a stainless steel reactor, the coolant inlet valve must be closed.

Drain the remaining refrigerant from both the pot and the jacket, then feed in the material and start the agitator.

Then, open the steam valve and the electric heating power supply. Once the desired temperature is reached,

First, close the steam valve and the electric heating power supply. After 2 to 3 minutes, then turn off the stirrer.

After processing is complete, once the remaining condensate in the pot and jacket has been drained, promptly rinse with warm water.

Scrape off the sticky material, then thoroughly clean the inner walls of the container with an alkaline solution at a temperature of 40℃ to 50℃.

Rinse thoroughly with clean water, especially when the stainless steel reactor vessel is empty—without any materials (heat-absorbing medium) inside.

Do not open the steam valve or the electric heating power supply. Pay special attention to the steam pressure.

The working pressure must not exceed the rated working pressure.

When maintaining a stainless steel reactor, you should regularly pay attention to the operating conditions of the entire equipment and the reducer.

If the reducer’s lubricating oil level is insufficient, it should be replenished immediately. The electric heating medium oil must be replaced every six months.

Safety valves, pressure gauges, distillation ports, and electric heating rods located on the jacket and lid of the pot, etc.

Electrical instruments and other equipment should be inspected regularly. If any faults are found, they should be replaced or repaired immediately. When the equipment is not in use,

Be sure to thoroughly clean both the inside and outside walls of the container with lukewarm water, and regularly scrub the pot body.

Keep the exterior clean and the inner lining bright to ensure durability.

Local Repair of Damaged Inner Wall of Reactor Vessel

Local Repair of Damaged Inner Wall of Reactor Vessel

The reaction vessel is an indispensable corrosion-resistant piece of equipment in the chemical industry. During use, mechanical impacts...

Sudden temperature changes and other factors often cause chipping, cracks, bubbles, porosity, and other defects in the surface glaze.

These defects are absolutely unacceptable in enamel equipment, and if they do occur, they must be repaired immediately.

The on-site repair agent made of polymer composite materials consists of polymeric polymers,

A two-component composite material based on alloy steel powder or wear-resistant ceramic powder, formulated with a curing agent.

Compared to conventional resin-based repair agents, polymer composite materials rely on their own more compact and refined polymer structure.

This enables the material itself to have stronger adhesion as well as excellent corrosion resistance and anti-corrosion performance.

Polymers can even penetrate into metals, forming a denser polymer-composite protective layer.

Repair process: Surface cleaning → Rust removal → Cleaning with anhydrous alcohol → Application of base-layer repair agent → Application of top-layer repair agent → Curing → Use
