Premium Quality Stainless Steel 317 and 317L Flanges Supplier from India Tricon Steel & Alloys. These Products are high-performance components known for their exceptional corrosion resistance and durability in demanding environments.

Stainless Steel 317 FlangesThese: These flanges are prepared from a chromium-nickel-molybdenum alloy, enhancing their resistance to corrosive substances such as acids, chemicals, and chlorides, making them suitable for use in harsh industrial settings. Including molybdenum further improves their resistance to pitting and crevice corrosion, ensuring prolonged service life even in challenging conditions.

One of the key Benefits of Stainless Steel 317L Flanges is their versatility. They are available in various types, including slip-on, weld neck, blind, socket weld, and lap joint flanges. They cater to diverse application requirements across industries such as chemical processing, petrochemical, pharmaceutical, and food processing. These flanges offer ease of installation and provide a secure, leak-proof connection, which is critical for maintaining the integrity of piping systems in demanding applications.

SS 317L corrosion resistance and versatility: Stainless Steel 317L Flanges exhibit excellent mechanical properties, including high tensile strength. They can withstand elevated temperatures without compromising their structural integrity, making them suitable for high-temperature and cryogenic applications.

Stainless Steel 317 / 317L Flanges

Stainless Steel 317/317L Flanges adhere to industry standards such as ASTM A182, ASME B16.5, and ASME B16.47, ensuring quality, dimensional accuracy, and compatibility with piping systems. Testing is crucial to ensure the quality and reliability of SS 317 flanges. Various tests are conducted during manufacturing to assess their performance characteristics and adherence to industry standards. These tests may include hydrostatic testing, ultrasonic testing, radiographic testing, and visual inspection, among others. Each test is designed to detect defects or irregularities in the flanges, ensuring they meet the specified requirements for strength, integrity, and dimensional accuracy.

317L Stainless Steel Flanges Manufacturing Process

Flange Forging

Compared to cast flanges, forged flanges typically contain less carbon and are less likely to corrode. Forgings have superior mechanical qualities, a thicker structure, and a more streamlined shape.

Heat Treatment

The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds. The flange is undergoing heat treatment; the forging process has the slowest total cooling pace, while the standardizing and reducing processes have faster cooling speeds.

Forging Rolling

Roll forging is a forging technique that shapes a metal object by using opposing rolls. Although roll forging employs rolls to accomplish the desired material deformation, it is categorized as a metal forging procedure rather than a rolling procedure.

Rust Prevention

For steel flanges, conventional rust protection treatments include hot dip galvanizing, electro galvanizing (cold), varnish paint coating, black paint coating, black phosphating treatment, yellow (golden) paint coating, etc.
