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.
Valve Removal Plugs are threaded plugs that can be installed in the wellhead to enable gate-valve removal under pressure. Valve Removal Plug material as a minimum meets the requirement of PSL3. Material is in accordance with material designation 60K for 13.8 MPA to 69 MPA working pressure & 75k for 103.5 MPA to 138 MPA working pressure The material requirement of Valve removal plugs shall be for sour services (DD, FF or HH). Valve removal plugs threads are coated to minimize galling and to develop maximum leak resistance. Valve Removal Plugs are not designed for use with test and blind flanges. There are 4 sizes and 2 pressure ratings available.
Bull Plugs are threaded nipple with a rounded, closed end used to stop up a hole or close off the end of a line. Pressure-containing closer for a female threaded and or outlet connection which may have an internal counter bore and/or test port. The Material & Design of Bull Plugs are determined with the working pressure and external load capacity. Bull Plug material as a minimum meets the requirement of PSL 3 material in accordance with material designation 60K for 13.8 MPA to 69 MPA working pressure. The material requirement of Bull Plug shall be for sour services (DD, FF or HH). Bull Plug conforms to the dimension and tolerance for NPT Size 4 Inch & Larger inline pipe size.
