• Slip-on Flanges

  The slip-on flange has a low hub because the pipe slips into the   flange prior to welding. It is welded both inside and out to provide   sufficient strength and prevent leakage. Slip-on flanges are all   bored slightly larger than the O.D. of the matching pipe.

• Welding Neck Flanges

  The welding neck flange is normally referred to as the “high hub”   flange. It is designed to transfers tresses to the pipe, there by   reducing high stress concentrations at the base of the flange.

• Threaded Flanges

  The threaded flange is similar to the slip-on flange, but the bore is   threaded. Very important that it can be assembled without welding,   example its use in low pressure service at ordinary Temperatures, and   in highly explosive areas where welding create risk.

• Blind Flanges

The blind flange is a flange without a bore. It is used to close off the ends of a piping system and/or a pressure   vessel opening. It also permits easy access to the interior of a line of vessel once it has been sealed and must   be reopened.
