Weld Nozzle Flanges, SAE Weld Nozzle Flanges , Swievel Flanges
  • Weld Nozzle Flanges are designed with Butt weld type to weld the pipe on both the side to the attached Nozzle.
  • Weld Nozzle Flanges are consists of Set of Split Flanges assembled with Weld nozzle both side with O ring, Allen Bolts & Nuts.
  • Weld Nozzle Flanges are easy for assembled, weld & ease of removal during assembly or disassembly of Piping Joints.
  • SAE Weld Nozzle Flanges are used for Bigger sizes of Joints in the piping conncetion where Nut & ferrule asembly is not possible.


  • SAE Weld Nozzle Flanges are in MOC - Steel, Stainless Steel SAE weld Nozzle Flanges are assembled with Split flanges or Mono Flanges or Flat Socket type flanges with Weld Nozzle on both side having O ring Seal groove.
  • SAE Weld Nozzle Flanges are designed as per ISO 6162 with Static Pressure for 3000 psi & 6000 psi Series.
  • Sizes Available - 1/4" NB up to 5" NB



  • CETOP Flanges
  • CETOP Flanges and ISO 6164 Specify Flanges with Butt weld ends and Square clamping Flanges for 250 bar and 400 bas static working Pressure respectively.
  • These correspond to 160 bar and 315 Bar dynamic Working Pressures. The Flange System consist of a Sleeve to be Butt or Socket Welded to the Pipe and clamped together betwwen two square Flanges by a set of four Hex bolts, Nuts and Spring washers, One of the sleeves carries an O ring groove fitted with an O ring for sealing the interface.
  • CETOP Flanges are designed as per CETOP RP 63H with consist of Sqaure Flange Body with Swievel Weld Nozzle either on One side or on both side as per Piping assembly Requirements.
  • Many a times , with the introduction of more corrosive fluids in piping systems, the total joint is not required to be of non -corrosive material, e.g. - Stainless Steel - SS only the sleeves which are wetted by the fluid are required to be of SS.
  • This makes for an economical Joint.


  • CETOP Flanges are available in 3000 & 6000 Psi Series.
  • CETOP Flanges are available in Steel & Stainless Steel MOC.
  • CETOP Flanges are available in sizes up to 5" NB to weld pipe.


  • Sqaure Flanges
  • The use of ISO 6164 Flanges has one disadvantage, The size of the Square Flange require a higher pitch between pipes due to the Flange Sizes.
  • In order to reduce the distance between pipes, SAE introduced their own Standards which are now incorporated in to ISO 6162 for the 3000 psi and 6000 psi static Pressure ranges respectivelty.
  • SAE system depends on the same set of butt welding sleeves held together by a set of Split Flange and Solid Flange secured by Hex Bolts and Nut.
  • Many a times, with the introduction of more corrosive fluids in piping systems, the total joint is not required to be of non -corrosive material, e.g. - Stainless Steel - SS only the sleeves which are wetted by the fluid are required to be of SS.
  • This makes for an economical Joint.


  • Sqaure Flanges are designed as per ISO 6164 standards.
  • Sqaure Flanges are assembled with 4 bolts & nuts.
  • Sqaure Flanges are available in Steel & Stainless Steel MOC.
  • Sqaure Flanges are available in sizes up to 5" NB to weld pipe.
