NipoFlange

A Nippo Flange is an integration of a welding nipple and a flange, often used for branch connections where space is limited. It is ideal for high-pressure systems requiring strong welded joints. The compact and sturdy design makes Nippo flanges suitable for applications in oil & gas, petrochemical, and power generation industries.

Customization Available: Tailor-made solutions for barrel length, bore size, bevel ends, and flange faces (RF, RTJ, FF) to suit your project needs.

Weldoflange
A Weldo Flange is a combination of a weld neck flange with integral O-let fitting. It is used as a branch connection and is directly welded to the run pipe, ensuring high integrity in high-pressure applications. Weldo flanges provide a smooth flow transition from the header to the branch line and are commonly used in refineries, chemical plants, and offshore facilities. 
O-let Fittings
  • Sizes: ½” to 20”
  • Standard: ASME B31.3, Client Drawing
  • Types: Weldolet, Sockolet, Threadolet, Latrolet, Sweepolet, Nipolet
  • Material Grades: Incoloy, Alloy 20, Hastelloy, Cupronickel, Monel 400, Inconel, Titanium, Urea Grade, Duplex/Super Duplex, Stainless Steel, Alloy Steel, Carbon Steel

Applications: Used to connect branch pipes to main run pipes with reinforced strength per ASME B31.3. Suitable for high-pressure and high-temperature piping systems in oil & gas, petrochemical, and industrial sectors. Machined forged pieces provide structural integrity and prevent leaks at connection points.
