Prithviraj Industries manufactures 6B and 6BX flanges in various sizes & pressure ratings as per API 6A. Most common material is low alloy steel AISI 4130. AISI 410 or UNS 31803 which are used for some of the critical services. Application of CRA (SS 316 or Nickel alloy 625) enhance the corrosion resistance ability of ring groove, thus enhancing the product life.
Prithviraj Industries manufactures metallic Ring Joint Gaskets which are suitable for high pressure and high temperature applications. The Gaskets are available in R, RX, BX styles and in oval/octagonal profiles. In addition, these units are manufactured in accordance with specific tolerances on CNC machines. Our Ring Joint Gaskets fully comply with the ASME B16.20 standard and the API spec 6A requirements (wherever applicable).
The Units Are Manufactured In A Variety Of Standard And Special Materials As Mentioned In Tables Below
