Flange Features
1.Easy Installation: Flanges are connected via bolts, eliminating the need for complex welding processes and specialized equipment, simplifying installation and improving construction efficiency.
2.Reliable Sealing Performance: Effectively prevents fluid leakage, ensuring good sealing within certain pressure and temperature ranges when correctly installed and used.
3.Strong Compatibility: Can connect with pipes and equipment of various materials and types.
Clad Flange (Overlay Welding Clad)
Clad Flange (Overlay Welding Clad) is an advanced flange fitting made by applying a high-performance alloy layer onto the surface of a base metal through a Overlay Welding process. This technique enhances the flange’s resistance to corrosion, wear, and high-temperature conditions, making it ideal for demanding applications in industries such as oil and gas, chemical processing, and power generation. The surfacing process not only strengthens the surface but also improves the flange’s overall durability and performance, allowing it to withstand harsh environments that would typically degrade standard flanges.
The clad structure of the flange ensures the combination of mechanical strength from the base metal with superior surface protection from the alloy layer, providing a longer service life and reducing the need for frequent replacements. The surfacing welding method allows for precise control over the thickness and quality of the alloy layer, optimizing the flange for both high-pressure and high-temperature applications. With enhanced resistance to abrasion and chemicals, Composite Flanges are a reliable, cost-effective solution for securing connections in critical systems where traditional flanges might fail prematurely.
Carbon Steel &stainless Steel Flange
Carbon Steel and Stainless Steel Flanges are essential components used to connect pipes, valves, and other equipment in various industrial systems. Carbon steel flanges are known for their strength, durability, and cost-effectiveness, making them a popular choice in applications where high pressure and temperature resistance are required, such as in the oil and gas, power, and construction industries. While they offer excellent structural integrity, carbon steel flanges may be prone to corrosion in harsh environments, which is why they are often used in non-corrosive or low-corrosive applications, or when additional protective coatings are applied.
On the other hand, Stainless Steel Flanges provide superior resistance to corrosion, oxidation, and staining, making them ideal for use in environments where exposure to moisture, chemicals, and extreme temperatures is a concern. Stainless steel flanges are commonly used in the chemical, pharmaceutical, and food processing industries, where hygiene and durability are critical. They offer long-term reliability and can handle both high-pressure and high-temperature conditions without compromising on performance. Whether for corrosive or high-stress applications, both carbon steel and stainless steel flanges offer tailored solutions for a wide range of piping and connection needs.
