Nickel Alloy Flanges

KANAKRATNA STEELAGE supplies a wide range of quality industrial forged steel pressure flanges and fittings including slip-on flanges, socket weld flanges, blind flanges and other shapes for connection applications in the oil, gas, chemical, wind, pharmaceutical and other industries, manufactured in accordance with ASTM, ANSI, ASME, API and other engineering standards.

The types of flanges are described and shown below:


  • Forged Weld Neck Ring Flangeweld neck flange drawing Weld neck flanges are circumferentially welded at the neck where the integrity of the butt welded area can be easily examined by radiography. The bores of both pipe and flange match, which reduces turbulence and erosion inside the pipeline. The weld neck is therefore durable in critical applications.


  • Forged Slip-On Ring Flangeslip on flange Slip-on flanges are fitted over the pipe and then fillet welded. Slip-on flanges are easy to use in fabricated applications.


  • Forged Blind Ring Flangeblind flange drawing Blind flanges are used to blank off pipelines, valves and pumps. They can also be used as an inspection cover. It is sometimes referred to as a blanking flange.


  • Forged Socket Weld Ring Flangesocket weld flange drawing Socket weld ring flanges are counter-bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same to provide good flow characteristics.


  • Forged Threaded Ring Flangethreaded flange drawing Threaded flange are referred to as either threaded or screwed. They are used to connect other threaded components in low pressure, non-critical applications. No welding is required.


  • Forged Lap Joint Ring Flangelap joint flange drawingLap joint flanges are always used with either a stub end or taft which is butt welded to the pipe with the flange loose behind it. This means the stub end or taft always makes the face. A lap joint is used in low pressure applications because it is easily assembled and aligned. To reduce costs, these flanges are supplied without a hub.

Product Details:
Material StandardANSI B16.5, ANSI B16.47, MSS SP44, ANSI B16.36, ANSI B16.48
We are one of the Leading, manufactures & suppliers of Slip On Flanges.

Slip On Flanges are a popular type of pipe flanges. These are type of flanges that slide over the end of piping and then welded in place. These flanges are ideal for lower pressure applications. These are easily fitted and welded into different pipes. Welding reduces fabrication costs of these pipes. These are available in wide variety of sizes and applications.

Material Used:Common materials used are as follows :
  • Stainless steel
  • Brass
  • Steel
  • Alloy Steel
  • Aluminum
  • Plastics
  • Titanium
  • Monels
  • Carbon steel
  • Alloy titanium etc.

Advantages of Slip on flanges :
  • Low cost installation
  • Less time needed to spent on ensuring the accuracy of the cut pipe
  • They are somewhat easier to align
  • The slip-on flanges have low hub because the pipe slips into the flange before welding
  • The flange is welded both inside and outside to provide sufficient strength
  • They prevent leakage

Key Features :
Some important features are as follows :
  • One size fits all pipe schedules.
  • Fabricators can more easily cut pipe to length for slip-on flanges.
  • The smaller thickness of this flange allows for easier alignment of bolting holes.
  • They are generally not preferred for high pressure temperature environments.
