Pipeline Branch Connections

Both types of piping intersections can meet the pressure reinforcement requirements of most international piping codes. The reinforced stub-in requires more carefully supervised workmanship, but can be less expensive in the third world with low labor rates. The Bonney Forge weldolet, in my opinion is usually a superior joint.

Weldolets are not available in all materials, however a reinforced stub-in can be fabricated from virtually all piping materials

If, by "better" you mean stronger, then the forged weldolet is a better choice. Werldolets have lower calculated Stress Intensification Factors (as per B31.1 and B31.3) in case you are performing stress analysis with your purloined copy of CEASAR or similar program.

It is important to note that the USA Bonney Forge company, who developed the weldolet, swepolet, elbowlet and spent miliions in development has been run out of business by cheap, third world imitations.

India, China and many other countries who refuse to respect trademaks and patent law have destroyed this fine Pennsylvania company and superb center of research.

Defective, poorly forged products called "weldolts" currently flood the market
