DN10 To DN1000 Class B Class D Flange AWWA C207-07 Rings Blind Forged Flanges

Types and Standard

• Carbon Steel Flanges are manufactured either by forging or by casting.

• Differences between forged steel flange and cast iron flange

• Forging process is more expensive than the cast iron process
• Casting iron can be manufactured to fit different complex profiles
• Forging process doesn't lead to the manufacture of big or uneven brain
• Cast iron flange is used exclusively for non-pressure pipelines, while forged Steel Flange is used in higher pressure pipeline
• The centrifugal machine is used to manufacture high precision cast iron flange than standard cast flanges
• Forged Steel can easily be cut, and it can withstand higher tensile strength
• Overall, forged steel is better than cast iron flanges in terms of performance as it comes with a better shape and also much lower carbon content which leads to less rusting.

• Referred Standards:

• B16.5 Dimensional standard for steel pipe flanges and flanges fittings
• B16.34 Valves connect by flanges, threaded and welding end
• B16.47 Large diameter steel flanges
• SP44 Standard for steel pipe line flanges
• API 605 large diameter carbon steel flanges

• Coating Types

  There are several types of coatings to protect carbon steel flange from rusting or corrosion:

• Anti-rust painting
• Oil Varnished
• Electric zinc coated (White or yellow zinc)
• Alloy material coated (Lined or Clad)

• Carbon Steel Flange Types

• Weld Neck Flange
• Slip On Flange
• Blind Flange
• Socket Weld Flange
• Threaded Flange
• Reducing Flanges
