Weldo Flange
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.
Nippo Flange
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.
