Types of Stainless Steel Flanges

Naysha Steel which is always committed to produce stainless steel flanges in raised standards is offering variety of flange type in order to supply to multiple industrial applications. Our fitting range consists of Weld Neck Flanges, Slip-On Flanges, Blind Flanges, Socket Weld Flanges, and Threaded Flanges. Weld Neck Flanges, one of the main products of the company, is steadily gaining ground for their immense strength and high resistance to pressure where these flanges find their application as very suitable elements. Slip-On Flanges possess the advantages of simple installation and the ability to work with low-pressure systems of a pipework. In the event of Blind Flanges being introduced these would seal the piping system efficiently. The Socket Weld Flange excels at resisting high compared to other flange types, making it an ideal choice for demanding high-pressure applications. However, the choice may depend on the application since the Threaded Flanges may be chosen due to their convenient installation without any welding.

Uses of Stainless Steel Flanges

  • Stainless steel flanges that can firmly hold the pipes together provide regular flow of fluids within the varied industrial processes and operational conditions.
  • Leak-proof connections such as flanges provided in these machines do the function of not allowing leakage of fluids and contamination, thereby maintaining the safety and efficiency of the operations of the industries.
  • Premium-quality stainless steel flanges are much resistant to corrosion and are thus more durable in environments where other substances could not withstand corrosion.
  • Efficient fluid control with less leakages is enabled by connection flanges thanks to the tight seals the flanges offer. This allows for more precise regulation of flow rates and pressure levels.
  • Installing the stainless steel flange improves safety standards and the work environment since it eliminates leaks and causes the system to be efficient.
