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


What is Stainless Steel 316L Flanges?
The low carbon variant of the stainless steel 316 grade material is known as stainless steel 316L. Along with steel of grades 304, 304L, and 316, it is one of the steels that is used the most in the world. Molybdenum is a component of the alloy that gives the stainless steel 316L flanges more corrosion resistance than the 304 grade flanges. For the 316L grade, various flange types are available, including slip-on, weld neck, socket, weld, and threaded flanges. They are utilised for many reasons and have a variety of structures.
The Stainless Steel 316L Flanges due to the existence of low carbon content, offer superior weldability. By lowering intergranular corrosion and carbide precipitate at the welded site, they aid in reducing localised corrosion. Additionally, they come in a variety of faces, which aids in serving a variety of functions.
In a variety of industries and for a variety of purposes, stainless steel 316L flanges are employed. Some examples include food processing equipment (particularly in chloride environments), maritime, architectural, pharmaceutical, chemical, and many more.
The high-temperature and high-pressure services are an excellent fit for the stainless steel 316L flanges. They are used extensively in marine and construction applications because of this, which is one of the key reasons. It exhibits good corrosion resistance and gains strength at high temperatures. Heat treatment does not cause it to become harder, and it is easily formable and drawable. It is a well-liked option for situations involving high temperatures and high corrosion.

SA182 F316l Slip on Flanges Vs ASTM A182 F316l RTJ Flange
The SA182 F316l Slip on Flanges are affordable and readily available. They include a low hub that makes it simple for the pipe to slide inside the flange before welding. From the inside as well as the exterior, these flanges are simply positioned and welded. Customers can purchase slide-on flanges with additional face types in addition to RTJ SA182 F316l slip on flanges. They are frequently employed in applications where there is a space restriction and they aid in reducing the line size. To strengthen the connection and stop leaks, these flanges are doubly welded on the inside and outside. They are mostly utilised in fluid applications with high temperature and low pressure systems.
The ASTM A182 F316l RTJ Flange (ring type joint flange) has an oval or rectangular ring joint gasket-accommodating circular groove. The two flanges are essentially bolted together and tightened in order for the resulting bolting force to assist in deforming the gaskets inside the flange groove. This aids in forming a tight seal. The ASTM A182 F316l RTJ Flange is typically utilised in high-temperature and high-pressure applications. Since the former is a type of flange and RTJ is a face-type for the flanges, customers can obtain slip-on flanges with elevated RTJ faces.

UNS S31603 Socket Weld Flange Vs A182 Gr F316l Threaded Flange
Since both flanges are constructed of SS 316L grade material, their characteristics would be equivalent. The primary distinction between them, nevertheless, is in their structural differences.
UNS S31603 Socket Weld Flange can be characterised as end connections that are made so that the flanges' dimensions are precisely matched to the pipe's dimensions. Due to the fact that they are welded to the piping system, these are frequently employed for high-pressure pipelines and those that do not require frequent disassembly. The socket weld flange assures a leak-proof connection for a longer period of time because of the strong weld.
TheWhat is Stainless Steel 316L Flanges?is ideal for applications requiring minimal pressure. This end connection is reasonably priced, simple to manufacture, and hassle-free to install. They are therefore applied to pipes that demand regular disassembly, inspection, upkeep, and alterations. After the joints have been put together, the threaded flanges are occasionally welded all the way around them. However, it might affect how well the threaded valve end connections are used.

Can 316L Stainless Steel Flanges rust?
Stainless steel can rust and develop an oxide coating on its top surface. However, the alloy of the Can 316L Stainless Steel material contains chromium, which would shield it from rusting. The passivation film theory is the mechanism behind SS 316L grade material's corrosion resistance. It aids the SS 316L material's ability to withstand corrosion in various media conditions.

  • 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.
  • 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.
