Astec Tubes is a leading name in the industry for serving out the wide variety of SS 316 / 316L Flanges. Flanges are very important components of any piping industry for making a connection. Therefore, we produce all the common and special flanges for completing your need for flanges. In short, clients can get a wide range of flanges that differ in specifications and dimensions for their requirements.

Flanges are commonly a known product for providing a connection to the pipes. They are a very popular way of making a connection after the method of welding. On contrary to welding, flange connection allows easy dismantling of pipes hence they are popularly preferred. As a result, you get maintenance flexibility. The flanges can connect a pipe with various other components like valves and more. However, the connection is made using gaskets and bolts.

The SS 316 / 316L Flanges are classified based on connection to be made, flange facing types, material types, and pressure-temperature ratings. As per flanges types, there are threaded flanges, socket weld flanges, slip-on flanges, lap joint flanges, weld neck flanges, and blind flanges. And based on flange facing types, we produce tongue and groove type, male and female type; ring joint, raised face, and flat face. And when we talk about the pressure-temperature rating, the flanges are classified based on the alloy used to make it.

Our SS 316 / 316L Flanges have high-pressure temperature ratings that make them perfect product for withstanding high pressure and temperature. This is because the SS 316 and 316 L is most sought material for manufacturing these flanges. There better corrosion-resistant property is making them a widely used material. In addition to this, pitting resistant and crevice corrosion are few of the properties that make our flanges a highly demanded product.

Henceforth, many industries demand our flanges where they provide secure connections. Industries like rubber industry, chemical processing equipment, pollution control, paper and pulp industry, pharmaceutical industries, and more are demanding for these flanges. The low carbon variant of the stainless steel is also used for making these flanges of the highest quality.
