Anucha Metals is one of the reliable Stainless Steel 304 Flanges suppliers in Bangkok, Thailand, with high-quality flanges for pressure piping and structural use. SS 304 flanges have superior corrosion resistance, formability, and weldability, well suited for water supply systems, chemical plants, and food-grade uses. Come in different types such as slip-on, weld neck, socket weld, blind, and lap joint, all the flanges are manufactured to ASME B16.5, ASTM A182, and other international standards. Our 304 flanges are long-lasting, dimensionally precise, and ideal for high-temperature and sanitary service conditions.
SS 304 flanges contain 18% chromium and 8% nickel, which provides them with tensile strength ~515 MPa, and yield strength ~205 MPa. They have good resistance to corrosion and oxidation, particularly in mild corrosive and ambient environments. The flanges are strong at elevated temperatures and possess good weldability and toughness, even at cryogenic temperatures.

Chanchai Stainless follows high-quality standards for its Stainless Steel 304 Flanges. Every flange is thoroughly tested for dimensional checks, visual inspections, and non-destructive testing such as ultrasonic and magnetic particle tests. In addition to that, the flanges are even submitted to mechanical testing in terms of tensile, hardness, and impact tests to confirm their strength and durability. All the products have the relevant certificates. They also carry material test reports (MTRs) and meet international standards. This will provide reliable performance in various industrial applications.
SS 304 long weld neck flanges are designed for high-stress applications, featuring a long tapered neck that provides a strong, continuous weld connection. They offer excellent strength and resistance to leakage.
SS 304 lap joint flanges are versatile components designed for ease of assembly and disassembly. They feature a loose fit, allowing for easy alignment and maintenance, with excellent resistance to corrosion.
SS 304 reducing flanges are used to connect pipes of different diameters, providing a smooth transition between sizes. They ensure a secure, leak-proof joint while offering strong corrosion resistance and durability.
304 stainless steel flanges find application in water treatment plants, chemical processing industries, pharmaceutical equipment, dairy & food processing units, and applications in the sea. They are required in pipeline systems, valve and pump connections, manifolds, and storage tanks. In sanitary surroundings, SS 304 flanges provide clean connections without compromising the hygiene. They have an appearance fit for decorative architectural piping, brewery hardware, and compressed air systems as well. SS 304 flanges are a standard industry solution for corrosive and moderate-pressure fluid systems.
