Description

The generalized understanding of stainless steel reactor is the vessel through the structural design and parameter configuration to realize the functions of heating, evaporation, cooling and low-speed and high-speed mixing required by the process with physical or chemical reaction.It is widely used in petroleum, chemical, food, medicine, pesticide, scientific research and other industries to complete the reaction equipment of polymerization, condensation, vulcanization, alkylation, hydrogenation and many processes of inorganic/organic and intermediates. It is suitable for large-scale or batch production in various enterprises under the conditions of high temperature, high pressure, high vacuum, high speed, suspension and convection, the reaction medium can be completely in a static sealing state to react with harsh media such as flammable, explosive, highly toxic, hydrogen, hydrofluoric acid and so on.

The structure of stainless steel jacketed reactor mainly includes a top cover with nozzles, a integral closed vessel, a top insert agitator, motor-gear driving device, shaft seal, U type or limpet coil type heating/cooling jacket, bottom flush valve, temperature and pressure measurement device, CIP/SIP device and etc.

Resistance to corrosion and staining, easy clean and sterilize, low maintenance, and familiar luster make stainless steel reactor an ideal for many applications where both the strength, cleaness and corrosion resistance are required.

PROPERTY OF COMMON USE SST MATERIAL

Stainless steel is a group of ferrous alloys that prevents the iron from rusting. Stainless steel's resistance to rusting results from the presence of chromium in the alloy, which forms a passive film that protects the underlying material from corrosion attack.

Model/Code/Type 304 is the most widely used kind of chromium-nickel austenitic stainless steel with good corrosion resistance, heat resistance, low temperature strength and mechanical properties; good hot workability by stamp and bend, no heat treatment hardening phenomenon (application temperature -196 ℃ to 800℃). It has good processability and weldability. The disadvantage is corrosion very fast in the presence of chloride ions, even exceeding than carbon steel.

Model/Code/Type 316L is the second widely used kind of low-carbon content chromium-nickel-molybdenum austenitic stainless steel，the added molybdenum content improves resistance to pitting corrosion and provides greater resistance to acids and localized corrosion caused by chloride ions. 316L have carbon contents below 0.03% to avoid corrosion problems caused by welding. It is generally accepted that 316 has better corrosion resistance and is more corrosion resistant than 304 in high temperature environment. However, the corrosion rate is very fast in high temperature concentrated sulfuric acid environment.

Most of the existing 316L stainless steel plates for pressure vessels in the market are produced according to American standards. The American standard stipulates that the Ni content of 316L is 10 ~ 14%, and the Japanese standard stipulates that the Ni content of 316L is 12 ~ 15%. Therefore, when purchasing 316L products, customers need to confirm whether the products refer to ASTM or JIS standards.

Model/Code/Type 321 is chromium-nickel austenitic stainless steel, its properties are very similar to 304. However, due to the addition of metal titanium, it effectively controls the formation of chromium carbide and has better intercrystalline corrosion resistance and high temperature strength. 321 austenitic stainless steel has good corrosion resistance in the atmosphere. It applicated in outdoor equipment with high requirements for intercrystalline corrosion resistance, heat-resistant parts and parts with difficulty in heat treatment. It is widely used in petrochemical, electric power, bridge, automobile and other industries.

CAUTION

Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary mild steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry.
