Stainless steel 304 flanges are often used in various applications, from welding to the food industry. They are available in various finishes and sizes, from Weld-neck flanges to Slip-on and Reducing flanges.

Slip On Flanges

Stainless Steel 304 Flanges are made from grade 304. It is an austenitic steel alloy with a low carbon content, making it suitable for welding applications. It is also a good choice for high-pressure applications. Aside from its corrosion resistance, 304 flanges have the best heat resistance of any stainless steel. It can withstand up to 450℉.

Besides the standard 304 flanges, there are many other products. These include pipe fittings, flanged fittings, spouts, flanged outlets, pipe tees, and flanged outlets. These products are useful in the following industries: petrochemical, power, oil and gas, and pharmaceutical.

Aside from the usual suspects, a good place to start is with a look at the ANSI B16.5 standard. The standard flanges are manufactured in all pressure classes, making them a worthy addition to any pipeline. The standard flanges are in stock, making it easy for customers to choose the right flange for the job.

Weld Neck Flanges

Whether you are looking for a shiny new flange or a spiffy replacement for your old one, you can’t go wrong by choosing one of the many top-notch manufacturers out there.

As the name suggests, this is the highest grade of chromium-nickel alloy available. This material is a great choice for many waters and natural gas applications. Not to mention, it’s a great way to reduce turbulence in your pipeline. It is also well-suited for applications requiring low-pressure fittings and couplings.

The best thing about this particular flange is that it is not only a cinch to install but is also inexpensive to boot. In short, this is the perfect flange for your next big project.

Reducing Flanges

Stainless Steel 304 Flanges are used for piping systems. They are available in different types, sizes, and shapes. They have good corrosion resistance, processing characteristics, and welding qualities. These flanges are often used for transportation, chemical processing, and the food and beverage industry. These flanges are marked with the material, heat number, class, and dimensions. They are also available in different shapes, including round, square, and rectangular.

The most widely used stainless steel grade is grade 304. The material contains chromium and nickel and has excellent forming and welding properties. It is also used for equipment that can be exposed to acidic solutions. The low carbon content improves weldability. However, it reduces the condensed corrosion resistance around the weld. The material is also resistant to 3% acid at room temperature.

The material is available in two different grades: grade 304H and grade 316H. The letter grade has a higher carbon content and is suitable for higher-temperature services. In addition, it contains a small amount of molybdenum, which further increases corrosion resistance. It also has the same properties as the regular grade 304. However, it is more resistant to sulfuric acid at higher concentrations.

Lap Joints Flanges

Stainless steel lap joint flanges are used in systems that require frequent cleaning and inspection. They are similar to slip-on flanges but with a stub end added to the center. A lap joint flange consists of two parts, the Lap Joint Stub End and the Backing Flange. The lap joint stub end is butted welded to the pipe, while the backing flange is slid onto the pipe before welding. Both are manufactured from different materials.

The lap joint flange’s face is designed to extend far enough from the pipe end to place a weld bead. The back side of the flange is also welded. It can be welded with either a fillet weld or a phonograph finish. This phonograph finish can improve gasket adherence. The inner surface of the flange is also curved to match the radius of the stub end.

The lap joint flanges come in various dimensions, including ANSI flanges, DIN flanges, and ASME flanges. In addition, they can also be manufactured with other materials.
