ASTM A182 F53 Super Duplex Steel 2507 / S32750 Nipolet , MSS SP-97 Pipe Fitting
It functions as a hybrid of three components:
Weldolet/Nipolet (for branch integration)
Flange (for bolted connection)
This design eliminates intermediate welds, enhancing structural integrity and leak prevention.
ASTM A182 F53 Super Duplex Pipe Fitting Specification
A Nipolet combines a branch outlet fitting (similar to Weldolet) with a flange, forming an integrated unit for 90° branch connections3.
It functions as a hybrid of three components:
Weldolet/Nipolet (for branch integration)
Flange (for bolted connection)
This design eliminates intermediate welds, enhancing structural integrity and leak prevention.

Design and Testing of pipe olet
Reinforcement Principle: Forged fittings eliminate the need for external reinforcement by integrating extra material around the branch junction310.
Testing:
No Hydrostatic Testing: Fittings rely on validated design calculations instead of mandatory hydrotests10.
Non-Destructive Examination (NDE): Mandatory radiography/ultrasonic testing for weld integrity3.
Marking Requirements: Each fitting must include:
Manufacturer’s trademark, material grade (e.g., WPHY-52), size (Run NPS × Outlet NPS), and "SP-97"
