T.D. Williamson Hot Tapping and Plugging Fittings Fully Comply with New European Code

T.D. Williamson (TDW), the global pipeline solutions provider, is releasing a standard offering for isolation fittings that fully complies with the new EN-13480 code, the European standard that replaces national codes in many countries.

With their all-new engineered design—which the company calls the ProSeries™ Advantage—the TDW STOPPLE® and STOPPLE Plus fittings meet EN-13480’s high standard for safety.

Full compliance with EN-13480 means STOPPLE fittings with the ProSeries Advantage demonstrate strict adherence to the relevant code’s stringent requirements.

“Thanks to state-of-the-art, model-based engineering, TDW guarantees STOPPLE and STOPPLE Plus fittings are validated to EN-13480, without deviation or bypass,” Senior Product Manager David Stordeur said. “Traceable, verifiable and complete records support our design parameters and we welcome our customers to audit our work.”

The ProSeries Advantage ensures shorter lead time through a standardized product with high quality materials and a quality-controlled process. In addition, it optimizes on-site welding time.

Available for 4-inch through 36-inch STOPPLE and STOPPLE Plus systems in ANSI Class 600, each fitting is fully compatible with TDW equipment and is suitable for multiple applications and operating conditions.

For decades, hot tapping and plugging (HT&P) isolations have saved pipeline owners and operators time and money by allowing them to safely work on pressurized systems without interrupting product flow.

TDW free e-book shows why HT&P is a safe, reliable isolation solution for pipeline projects – from routine maintenance to urgent interventions, new construction to line expansions.


What’s in the e-book?

  • How the design, manufacturing and testing of HT&P equipment contribute to safe, successful pipeline projects, even under challenging conditions.
  • The positive impact hands-on training has on project safety.
  • How application engineering can further reduce uncertainty about your HT&P project when special circumstances exist.
  • The role of automation in ensuring equipment reliability and availability.
