New diaphragm materials available

diaphragm seal materials

Badotherm is continuously adding new diaphragm materials to its scope of supply. Adding new diaphragms is a complex activity. Next to finding the right materials, it also asks for extensive R&D activities, like testing diaphragm pressing techniques, flexibility calculations, prototyping, and weldability.

Below the complete list of diaphragm materials:

 

  • AISI 304
  • AISI 316L
  • AISI 316L UG
  • AISI 321
  • AISI310 MoLN / 25Cr22Ni2Mo
  • AISI 904L / Uranus B6
  • Hastelloy C-276
  • Hastelloy B2
  • Hastelloy C-22
  • Monel 400
  • Tantalum
  • Nickel 201
  • Niobium
  • Inconel 600
  • Inconel 625
  • Incoloy 825
  • Duplex 2205
  • Superduplex 2507
  • Titanium Gr.1
  • Zirconium
  • 254 SMO / 6MO

 

Diaphragm material availability has to be complementary with the body material of the diaphragm seal construction and the specific (welding) requirements of the materials. For more information, see the datasheet where you can check what materials are possible and suitable for specific diaphragm seal types. Badotherm aims to support their customers with the supply of the best material possible to meet their process requirements and corrosion resistance. Badotherm however does recommend or select any material; this is and remains always the end responsibility of the end user.
