EN 1.4404 Slip On Flange & ASTM A182 F316L BLRF Flange manufacturer in India

What is Stainless Steel 316L Flanges?
The Stainless Steel 316L material can be defined as the low carbon version of the SS 316 grade material. It is among one of the most used steel materials worldwide along with the grade 304, 304L, and 316 material. It consists of molybdenum in the alloy which makes the Stainless Steel 316L Flanges more resistant to corrosion compared to the 304 grade flanges. There are different types of flanges available for the 316L grade, like slip on, weld neck, socket, weld, and threaded flanges. They have varied structures and are used for different purposes.
The Stainless Steel 316L Flanges have good weldability due to the presence of low carbon content. They help in decreasing the localized corrosion by reducing the occurrence of intergranular corrosion and carbide precipitate at the welded site. They are also available in different types of faces, which helps to address different purposes.
The Stainless Steel 316L Flanges are used across a wide range of industries for different applications, like in the food processing equipment (especially in chloride environment), marine, architectural, pharmaceutical, chemical and many more.
The Stainless Steel 316L Flanges are a good choice for services that involve high-temperature and high-pressure. This is one of the main reasons why they are widely used in construction and marine applications. It shows good resistance to corrosion and has enhanced strength at elevated temperatures. It remains non-hardened by heat treatment and can be formed and drawn easily. It is a popular choice for high-temperature and high-corrosion applications.

SA182 F316l Slip on Flanges Vs ASTM A182 F316l RTJ Flange
The SA182 F316l Slip on Flanges are available at a very low cost. They come with a low hub through which the pipe can easily slip inside the flange before the welding process takes place. These flanges can be easily aligned welded, from both inside and outside. Clients can get RTJ SA182 F316l Slip on Flanges, as well as the slip-on flanges with other face types. They help to reduce the line size and are widely used for those applications where there is a space limitation. These flanges double welded in the inner and outer side, to enhance the connection strength and prevent leakages. They are mostly used for fluid applications which have low pressure and high temperature systems.
The ASTM A182 F316l RTJ Flange (ring type joint flange) has a circular groove for accommodation of an oval or rectangular ring joint gasket. The two flanges are basically bolted and tightened so that the resultant bolting force helps to deform the gaskets inside the groove of the flange. This helps create a tight seal. Typically, the ASTM A182 F316l RTJ Flange are used in high-pressure and high temperature applications. Clients can get slip-on flanges with raised RTJ faces, as the former is a type of flange and RTJ is a face-type for the flanges.

UNS S31603 Socket Weld Flange Vs A182 Gr F316l Threaded Flange
Both the flanges are made with the SS 316L grade material and hence they would possess similar properties. However, their structural difference is the main reason why they are different from one another.
UNS S31603 Socket Weld Flange can be described as end connections manufactured in such a way that the dimensions of the flanges are customized exactly according to the dimension of the pipe. These are widely used for high-pressure pipelines and for those which do not require frequent disassembling, because they are welded to join them with the piping system. Due to the strong weld, the socket weld flange confirms leak proof connection for a longer time period.
The What is Stainless Steel 316L Flanges? is the most suitable for low pressure applications. This end connection is affordable and can be assembled and installed quickly without any hassles. Hence they are used for those pipes that need frequent disassembling, inspection, maintenance and modifications. Sometimes, the threaded flanges are welded around the joints after they have been assembled.But it might cause issues with the efficient usage of the threaded valve end connections.

Can 316L Stainless Steel Flanges rust?
Stainless steel can get rusted and they form a layer of oxide on their top surface. But the Can 316L Stainless Steel material consists of chromium in its alloy, which would prevent it from getting rusted. The corrosion resistance mechanism for the SS 316L grade material is known as the passivation film theory. It helps the SS 316L material to resist corrosion in a wide range of media environments.

  • Stock Finish: The most commonly chosen flange surface finish since it is basically acceptable for all routine service situations. When compressed, the soft face of a gasket embeds into this finish, assisting in the formation of a seal, and a high amount of friction is formed between the mating surfaces.
  • Spiral Serrated: A continuous or phonographic spiral groove that differs from the stock finish in that the groove is often made with a 90-° tool that forms a "V" geometry with 45° angled serration.
  • Concentric Serrated: This finish has concentric grooves. Serrations are spread evenly over the face using a 90° tool.
  • Smooth Finish: This finish has no visible tool markings. These finishes are commonly used on gaskets with metal facings such double jacketed, flat steel, and corrugated metal.
