Screwed flange

Screwed flange is a type of flange attached to the pipeline system by threaded joints. The Screwed flange is internal thread and the pipe is an external thread. Stainless steel Screwed flange are manufactured from stainless steel materials SUS 304, 304L, 316, 316L.

Screwed stainless steel flanges are commonly used in small diameter pipeline systems and have the advantage of being easy to assemble without the need for pipe welding. Screwed flanges are suitable for low pressure, low temperature piping systems and systems that do not involve welding, burning and grinding because they will loosen the thread.

  • 304 and 316 stainless steel threaded flanges are resistant to chemicals and corrosives
  • Withstand high pressure and temperature environments
  • Highly practical, safe, low cost flanges can be fitted to pipes of different sizes without welding and this is a major benefit for which these flanges are highly demanded.

Applications of Screwed flanges in industry and in life

Screwed  flanges are commonly used in pipeline systems where welding cannot be used or where pipes are small in size or in flammable areas. Applications of stainless steel Screwed flanges are often used in:

  • Water pipeline system, wastewater discharge pipe.
  • Oil and compressed air filtration system.
  • Chemical production system.
  • Wine production system.
  • And some other systems.
