Alpha Nickel

Carbon Steel Flanges Manufacturer, Supplier In Mumbai India

Alpha Overseas is a well-known producer and supplier of carbon steel flanges. Carbon steel pipe flange material can only have minimum chromium, nickel, molybdenum, vanadium, and titanium content. The heat treatment on the flanges makes them more complex and more robust. There are various types based on the type, such as the carbon steel blind flange, which is used to close a connection. The CS flanges come with a collar or flare for bolt holes or welding.

We are one of India's most significant carbon steel flange manufacturers, producing these flanges in various sizes and types. There is various pressure based on the pressure capacities of the flanges. Class 150 carbon steel flange is the lowest class, with higher classes ranging up to 2500.

Carbon steel has a good yield strength in the range of 250 mpa minimum and tensile strength of 485 mpa minimum. Carbon steel spectacle blind flanges are another type of blind flange in which a ring and a plate are joined on the horizontal axis.

Carbon steel flanges have the following characteristics:

  • • Available in a variety of diameters,
  • • They require very little vertical flange space.
  • • It's simple to install and assemble.
  • • Low price

Our clients highly regard these due to their long life and resistance to wear and strain. We guarantee the premium quality of the entire range of items to be offered because we are committed to exceeding our valued customer's expectations. These flanges are almost certainly subjected to tests and inspections to determine their quality.

The tests include:

  • • A hydrostatic test.
  • • A destructive test.
  • • A flare test.
  • • A flattening test.
  • • A third-party inspection.
  • • A pitting resistance test.
  • • A macro- and micro-test.

These tests are carried out under the watchful eye of professionals and by industry laws and regulations. Finally, the carbon steel flanges are packaged and delivered to the clients.
