Hot tapping and plugging (HT&P) is a common method for accessing an in-service pipeline for tie-ins, repair, and maintenance. But as with most operations in the pipeline industry, “common” hardly equates to “simple.” Entering and isolating a pipeline is complex by nature.
Fortunately, technological advances are helping keep HT&P projects safe and on schedule. A recent innovation is the ProSeries range of HT&P fittings introduced by pipeline solutions provider T.D. Williamson (TDW).
ProSeries fittings expand the capabilities of the company’s STOPPLE and STOPPLE Plus fittings. Available for 4-inch through 36-inch, ProSeries fittings are engineered and manufactured using best-in-class processes. The result is a broader range of code-compliant fittings to address multiple applications and operating conditions – plus shorter lead times and substantially faster deliveries.
The fitting is a crucial element of the HT&P operation. Manufacturing or delivery delays can send a project off track, Paola Corrales, product manager – HT&P, said. By reducing ProSeries manufacturing time, TDW allows operators to optimise project schedules, so they can become more efficient and complete projects sooner.
“The ProSeries offering ensures operators will have the right fitting for their application, even in the most challenging isolation operation – on time, exactly when they need it,” she said. “Based on our innovative approach to design and production, TDW is also able to shorten delivery time of custom fittings for use in extremely unique applications.”
Consistent product quality is assured through model-based manufacturing, Corrales said. Compliance with ASME B31.1, B31.3, B31.4, B31.8; CSA Z662 CAT I and CAT II; CFR 192 and 195a; and a variety of ANSI and other codes has been proven and validated.
