High Conductivity Stainless Steel Coils Gr660/SUH660/316Ti/S31668 Factory Direct for Heat Exchanger Plates

Product Overview

Our high - conductivity stainless steel coils, available in Gr660, SUH660, 316Ti, and S31668 grades, are specifically designed for heat exchanger plates. These coils are sourced directly from our factory, ensuring high - quality products at competitive prices. With a focus on precision and performance, these stainless steel coils are an ideal choice for various industrial applications that require efficient heat transfer.

Surface Treatment

The surface of these stainless steel coils undergoes a polished treatment. This polished finish not only gives the coils an aesthetically pleasing appearance but also offers several functional benefits. Firstly, it reduces the surface roughness, which in turn minimizes the adhesion of contaminants. In heat exchanger applications, this is crucial as it helps maintain the efficiency of heat transfer by preventing the build - up of deposits that could act as insulators. Secondly, the polished surface enhances the corrosion resistance of the coils, increasing their lifespan and reliability in harsh operating environments.

Manufacturing Technique

These coils are produced using the hot - rolled technique. Hot rolling is a well - established manufacturing process that offers several advantages. During hot rolling, the steel is heated above its recrystallization temperature and then passed through rollers to achieve the desired thickness and shape. This process results in a more uniform grain structure within the steel, which improves its mechanical properties. The hot - rolled coils have better ductility and toughness compared to cold - rolled ones, making them more suitable for applications where the coils may need to be formed or bent during the manufacturing of heat exchanger plates.

Compliance with Standards

Our stainless steel coils strictly adhere to the ASTM standard. ASTM (American Society for Testing and Materials) standards are widely recognized and respected in the global market. By meeting these standards, our coils ensure high - quality and reliable performance. Whether it's the chemical composition, mechanical properties, or dimensional accuracy, our coils are manufactured to meet or exceed the requirements set by ASTM. This compliance also makes it easier for our international customers to integrate our products into their existing systems, as they can be confident in the quality and compatibility of the coils.

Grade - Specific Features

• Gr660/SUH660: These grades are known for their excellent high - temperature strength and oxidation resistance. In heat exchanger applications, where the coils are often exposed to high - temperature fluids, these properties are essential. They can withstand elevated temperatures without significant loss of strength, ensuring the long - term stability of the heat exchanger plates.
• 316Ti/S31668: The addition of titanium in these grades enhances their corrosion resistance, especially in environments containing chlorides. Chloride - induced corrosion is a common problem in many industrial settings, and the 316Ti and S31668 grades offer a reliable solution. They are also highly resistant to intergranular corrosion, which can occur at welds and other critical areas of the heat exchanger plates.

Factory Direct Advantages

As a manufacturer, we offer these stainless steel coils directly from our factory. This eliminates the middlemen, allowing us to offer more competitive prices to our customers. Additionally, we have full control over the production process, from raw material sourcing to the final inspection. This enables us to ensure consistent quality in every coil we produce. Our factory is equipped with state - of - the - art production and testing facilities. We have automated production lines that can produce large quantities of coils with high precision. Our advanced NDT (Non - Destructive Testing) services, such as Ultrasonic Testing (UT) to EN 10228 - 3 and Magnetic Particle Testing (MT), ensure that every coil is free from internal and surface defects.

Applications in Heat Exchanger Plates

In heat exchanger plates, our stainless steel coils play a vital role. Heat exchangers are used in a wide range of industries, including chemical processing, power generation, and HVAC systems. The high conductivity of our coils allows for efficient heat transfer between different fluids. The excellent corrosion resistance ensures that the heat exchanger plates can operate in corrosive environments without premature failure. The mechanical properties of the coils, such as their strength and ductility, enable them to withstand the pressure and stress that occur during the heat exchange process. Whether it's a small - scale heat exchanger in a laboratory or a large - scale industrial heat exchanger, our coils can provide reliable performance.
