What are the 7 benefits of Hastelloy C276 flanges?

A unique metallurgical composition – nickel, molybdenum, and chromium – makes these flanges highly desirable in the industrial realm. Hastelloy C276 flanges boast numerous advantages warranting their demand:

  • Good corrosion resistance (pitting, crevice corrosion, cracking due to stress, and intergranular)
  • Easy machinability due to the low carbon proportion. Cutting is straightforward and does not produce undue heat.
  • High strength
  • Good ductility and formability
  • Resistant to oxidation up to 1250°C
  • A Hastelloy C276 lap joint flanges is one of the lightest materials with this strength. In fact, it has a density of just 0.321 lb/in3.
  • High wear-and-tear resistance

We are Hastelloy flanges manufacturer in India that complies with  standards ASTM B564

Which welding technique is used for Hastelloy flanges?

Sensitive sectors, such as medical equipment and aerospace, utilise Hastelloy flanges. These components can be welded by standard techniques. But TIG or Tungsten Inert Gas welding is favoured for its stability and precision. A tungsten electrode (non-consumable) is employed for this process.

In TIG, the technician uses a welding rod from a wire feeder. This approach works for thinner components, needing a single pass through each side (it also works for thicker joints). The welding of a nickel C276 plate flanges uses a filler metal. However, a few applications may also turn to SMAW or shielded metal arc welding. It uses a consumable electrode.

We are an established and affordable supplier of Alloy C276 blind and slip on flanges in Mumbai as per ASME B16.5 standards

Alloy C276 blind flanges vs Werkstoff 2.4819 slip on flanges

The tolerance of these components is impressive: they can handle many acids, alkalis, and salts. Whether you pick a blind or a slip-on flanges will depend on the application’s needs. An Alloy C276 blind flanges closes off pipe ends for maintenance.

It can isolate a piping section and does not need to join two pipes. On the other hand, a Werkstoff 2.4819 slip on flanges is preferred for repeated or frequent disassembly. Installing it is direct – just sliding over and then welding.

As stockist we offer Werkstoff 2.4819 socket weld and weld neck flanges in various pressure rating such as Class 150 to Class 2500 and with the required certifications

What is the size range of Alloy C276 weld neck flanges available in the market, and are custom sizes available on request?

These flanges efficiently tackle high-pressure installations, avoiding a stress buildup at the bottom. An Alloy C276 weld neck flanges is available in sizes from 1/2 inches to 48 or up to 60. Buyers can select pressure classes from 150 to 2500 and the respective schedules from 10 to 160. Customisations may also be discussed per needs.

To elaborate on customisation: Mills follow global standards to produce these components but can make custom sizes based on drawings. You should select a contemporary manufacturer with state-of-the-art production capacities for these requirements.

Are there specific applications where ring joint face types are preferred for UNS N10276 socket weld flanges?

The ring joint face is the ideal choice for high-pressure applications. A UNS N10276 socket weld flanges with this face type is also suited to high temperatures.

Socket weld flanges usually work with pipes of small nominal sizes. With an RTJ face, their general applications are in chemical processing, aerospace, oil refineries, and paper production. These face types work in oil fields and pressure vessels.

How does hardness testing help assess the quality and integrity of DIN 2.4819 threaded flanges ?

Sectors like crude oil refining and pharmaceuticals require flanges showing sturdiness and high integrity. A DIN 2.4819 threaded flanges uses a material with a hardness of 40 HR or Brinell 230. Manufacturers use hardness tests like Rockwell, Brinell, Knoop, and Vickers to assess the properties ofAlloy C276 flanges.

Generally, these tests use a scratch-based or indentation method to judge the substance’s hardness. Products that match the desired properties are likelier to ensure safety and long-term performance in critical applications. Hardness tests are a part of most quality-control standards, with their results included in the Mill Test Certificate (MTC).
