ZECO stainless steel gate valve is basically used for pipelines with corrosive media. For any kind of stainless steel material, the ability to resist medium corrosion is relatively limited, and is affected by many external factors, such as temperature, pressure, PH. However, as long as the heat treatment and processing process are completely in accordance with the standard in the manufacturing process, the material can be guaranteed to withstand corrosion within the range of corrosion. So in the selection of stainless steel gate valve, we need to consider the concentration of medium, working environment temperature and the selection of materials and other factors on corrosion resistance. ZECO is a professional manufacturer of stainless steel gate valves for nearly 30 years, providing professional suggestions for users to choose models and materials for working conditions.
1. ZECO stainless steel gate valve has a variety of stainless steel materials for users to choose according to the actual working conditions, casting including ASTM A351 CF8, ASTM A351 CF8M, ASTM A351 CF3, ASTM A351 CF3M, forging including ASTM A182 F304, ASTM A182 F304L, ASTM A182 F316, ASTM A182 F316L, and duplex stainless steel UNS SS32205 and so on;
2. The raw materials suppliers selections of ZECO stainless steel gate valve is reference to international famous enterprises of the supply chain system standard. First of all, the first sample analysis report of ZECO quality inspection department is passed, and then the technical department evaluates it according to the supplier's management system and production process. Only after the evaluation and approval of the two departments, can it enter the business negotiation of the purchasing department. Later, it will test each batch of delivery by the supplier, so as to divide the procurement into different levels and batches;
3. ZECO stainless steel gate valve is designed with renewable seat for easy replacement in case of seat damage;
4. ZECO stainless steel gate valve has strong corrosion resistance and the material fully meets the requirements of international standards.
