Tank Flanges

Tank flanges are flanges most commonly used to connect a pipe to a vessel or tank of some kind. They can also be used to connect two pipes together. There are a few different types of this this of flange and they are applied to pipes or tanks depending on the material they are made of and what they are being applied to.

Aluminum or forged steel weld on tank flanges each need to be welded on to tanks of their corresponding material. They each have ready-made reservoir ports and can be welded to tanks once a hole is drilled into the tank the size of the flanges’ pilot. Steel and aluminum weld on tanks flanges are very sturdy and strong and are slimmer and less noticeable than other flanges once applied.

Polypropylene bolted tank flanges come with standard EPDM (a type of synthetic rubber) Gaskets. They are made of polypropylene that is reinforced by glass. These bolted tank flanges provide outstanding resistance against chemicals, corrosion and the cracking that derives from stress. They are rigid but also lightweight. Polypropylene “bottom drain” bolted tank flanges allow for full drainage of a tank once they are applied to the bottom of that tank. They are ultrasonically sealed through the use of bolt head plugs.

Tank flanges are used in many applications

Some tanks and other applications they are used for include:

  • Bolted Tanks
  • Distillates
  • Hydrocarbons
  • Oilfield Storage Tanks
  • Water Tanks

Unlike threaded or weld neck flanges, which work well in high pressure situations, tank flanges perform well when used for unpressurized machinery and vessels. High quality tank flanges from Detroit Nipple Works come in various materials and all different sizes and weights.
