Stainless Steel 347 Flanges

We are manufacturers of stainless steel flanges to serve the multiplying needs in several industries and have been working specialized in these for very many years. Our experienced engineers can manufacture flanges in standard specs or according to the client's need. SS 347 Flanges show great resistance to abrasion and high creep resistance factors, which make them suitable for application in conditions related to continuous heating, normally in the range of 800-1650°F.

The mechanical properties of SS 347 are retained at higher temperatures, making them suitable for numerous applications, such as aircraft exhaust stacks, expansion joints, treatment boxes, and boss rings. We make SS 347 Flanges in many different shapes, such as slip-on flanges, socket weld flanges, welding neck flanges, long weld neck flanges, reducing flanges, and so on.

Our excellence mantra is also reflected in the variety of stringent testing processes applied to ensure the quality of our products, from hardening to proof tests and dimensional checks, to PMI (Positive Material Identification), IGC (Intergranular Corrosion) tests at various levels, both small and full-sized. All the tested materials would further be sent beneath the eagle eyes of an expert team evaluating superior quality.

The raw material test reports, 100% radiography test approvals, and detailed inspection reports are accompanied by test certifications. The certifications and the accompanying documents are provided to the purchasers upon request. We package our products marked by strong environmental packaging materials in a bid to ensure that the flanges remain intact up to the time of dispatch. We promise safe ways of ensuring the products are delivered and that our deliveries find their way in optimal conditions to the clients in the different countries.
