Trusted Manufacturer Desalination Plant Applicable Stainless Steel Coils S32169/317L/S31703/S25073 for Membrane Housings

Introduction

In the realm of desalination plants, the choice of materials is crucial for ensuring the longevity and efficiency of the equipment. Our company, a trusted manufacturer since 2017, offers a range of high - quality stainless steel coils including S32169, 317L, S31703, and S25073, specifically designed for membrane housings. These coils are the result of years of research, development, and practical experience in the special steel industry.

Product Specifications

• Surface Treatment: The stainless steel coils undergo a polished surface treatment. This not only gives them an aesthetically pleasing appearance but also provides several functional benefits. A polished surface is smoother, which reduces the adhesion of contaminants and scaling agents. In a desalination plant, where the water can contain various impurities, this feature helps to maintain the cleanliness of the membrane housings and ensures the smooth flow of water through the system.
• Technique: They are produced using the hot - rolled technique. Hot rolling is a well - established manufacturing process that offers excellent mechanical properties to the stainless steel. It allows for the formation of a uniform grain structure, which enhances the strength and ductility of the coils. This means that the coils can withstand the high pressures and mechanical stresses typically encountered in desalination plants without cracking or deforming.
• Standard: Our stainless steel coils adhere to the ASTM standard. ASTM standards are widely recognized and respected in the international market. By following these standards, we ensure that our products meet the highest quality and safety requirements. This compliance also makes it easier for our international customers to integrate our coils into their existing desalination systems, as ASTM - compliant materials are commonly used in the industry.

Types of Stainless Steel Coils

• S32169: This type of stainless steel has good corrosion resistance, especially in environments with high chloride content. Chlorides are commonly found in seawater, and in a desalination plant, the membrane housings are constantly exposed to these corrosive elements. S32169 can resist pitting and crevice corrosion, which helps to extend the service life of the membrane housings.
• 317L: 317L stainless steel is known for its enhanced resistance to general corrosion and stress - corrosion cracking. It has a higher molybdenum content compared to some other stainless steels, which gives it better performance in aggressive chemical environments. In a desalination plant, where the water treatment process may involve the use of various chemicals, 317L is an ideal choice for membrane housings.
• S31703: Similar to 317L, S31703 offers excellent corrosion resistance. It has a balanced composition of elements that provides good mechanical properties and resistance to oxidation. This makes it suitable for long - term use in desalination plants, where the membrane housings need to maintain their integrity over an extended period.
• S25073: S25073 is a super duplex stainless steel. It combines the benefits of both austenitic and ferritic stainless steels. It has high strength and excellent corrosion resistance, especially in chloride - rich environments. The duplex structure also gives it good resistance to stress - corrosion cracking, making it a reliable option for membrane housings in desalination plants.

Company Background

Our company, Wuxi Weiman Gaodeng Special Steel Co., Ltd., has a rich history of growth and development. Starting in 2003 as a company focused on R & D and material solutions for power plant boiler steel, we have gradually expanded our expertise and product range. In 2017, we obtained important certifications such as ISO 9001:2015, API 5L, and EU PED, which allowed us to enter the international market. We have an annual export share ranging from US$5 Million - US$10 Million, and our products are sold in major markets around the world, including North America, South America, Europe, Asia, Africa, and Oceania. Our team consists of 11 - 20 experienced salespeople who are dedicated to providing excellent service to our international customers.

Company Services

• Customization: We understand that different desalination plants may have unique requirements. Therefore, we offer customized materials and value - added services. Whether it is adjusting the dimensions of the stainless steel coils or modifying the chemical composition to meet specific corrosion resistance needs, our technical team can work closely with customers to provide tailored solutions.
• Processing & Testing Capabilities: Our factory has advanced processing and testing facilities. We can fabricate welded elbows and flanges per ASME B16.9, and these products undergo radiographic testing (RT) and liquid penetrant testing (PT) to ensure their quality. We also offer custom - cutting services for plates (with a maximum thickness of 120mm) and pipes (with an outer diameter ranging from 20 - 1200mm). In terms of non - destructive testing (NDT), we use ultrasonic testing (UT) to EN 10228 - 3, which can detect internal defects as small as 0.5mm. Our magnetic particle testing (MT) for surface cracks is certified by SGS and BV, ensuring the reliability of our products.
