Key Features & Advantages

  • Premium 316L Material: Offers superior resistance to corrosion and high temperatures, ensuring a long service life even in harsh chemical or marine environments.

  • Type A Design & Unpolished Finish: Manufactured to strict specifications with an unpolished surface, making it suitable for systems where a non-reflective or standard industrial finish is required.

  • Butt Weld Connection: Features beveled ends that create a strong, flush weld when joined to pipe, allowing for maximum flow and easy inspection access.

  • Versatile Compatibility: Typically used with B38SL flanges, allowing for quick disconnection for system maintenance and cleaning.

3. Working Principle

The 14VB Stub End functions as a lap joint flange adapter. When welded to the end of a pipe, it provides a flat, perpendicular surface. A loose flange (backing ring) is slid over the stub end. When bolted to a mating flange, the stub end acts as the sealing surface, while the flange provides the mechanical clamping force. Critically, the flange is not welded to the pipe, which allows for rotational alignment and easy disassembly without disturbing the pipe weld.
