Flange DN150

General flange and flange DN150 is an accessory that pumps, valves, pipelines, and other machines use to bond, in order to create a unified structure on the pipeline.

It makes the replacement of pipes and other fittings easier.

Typically, flanges are screwed (threaded) or welded (threadless flanges). Flange joints are designed with small holes in a circle so that they can be connected to each other by bolt links.

And to make the connection tight, between the two flanges there will be a rubber seal (gasket).

Common flange types in the chemical and petroleum industries

The types of flanges want to be used for the petroleum, and chemical industry. Then, certain conditions must be complied with, in order to ensure the safety of the work and the operator.

  • Must be made of high-quality alloy or steel.
  • Good bearing capacity and absolute airtightness to avoid leakage problems. Due to the impact force from the movement of oil and gas, pressure from the flow of oil and gas through, thermal expansion.
  • The disassembly and operation of flanges need to optimize the steps. So that when problems arise, they can be replaced and repaired quickly



Types of flanges used in oil and gas

Types of flanges DN150 used for chemical and petroleum pipelines:

    • Weld neck flange
    • Sliding Flange
    • Flange coupling
    • Threaded Flange
    • Blind flange
