I Petrochemical Industry: Corrosion Resistance and Explosion Proofing Are Key
The working conditions in this industry are complex, involving flammable and explosive oil and gas, as well as acidic and alkaline solutions, often accompanied by high temperatures and pressures. It is recommended to use 316 stainless steel, which offers strong corrosion resistance and can withstand the erosion of crude oil and chemical solvents. Additionally, the explosion-proof and sealed design eliminates the risk of electric sparks.
II Pharmaceutical/Food Industry: Sterility and Hygiene are Core Principles
For processes such as pharmaceutical fermentation and food sterilization, equipment must be free of contamination, meet hygiene standards, and be explosion-proof in scenarios involving organic solvents. The selected material is food-grade 304 stainless steel, which is free of harmful substance leaching, complies with GMP standards, and can be directly used for pharmaceutical heating and canned sterilization.
III Electroplating Industry: Resistance to Strong Acids is the Priority
The plating pickling tank contains highly acidic solutions, which can corrode and cause leaks with ordinary materials, posing safety risks. Specialized titanium explosion-proof flange heating tubes are selected for their resistance to strong acids and high temperatures, ensuring stable long-term operation in the pickling solution.
Ⅳ Ship/Marine Engineering: Salt Fog Corrosion Resistance
The ship engine room and offshore platforms operate in highly humid and salt spray environments, requiring heating of fuel and hydraulic oil, which imposes extremely high demands on material corrosion resistance. Special corrosion-resistant treated 316L stainless steel can withstand salt spray erosion, offers excellent sealing performance, and is suitable for flammable and explosive working conditions.
In addition, industries such as coal chemical and environmental wastewater treatment customize suitable materials based on specific working conditions—304 stainless steel for general water heating, high-temperature resistant alloys for molten media, and titanium or Hastelloy for highly corrosive environments.
