Addresses copper leaching challenges in tracing lines

TLV CorpIn June, the P21S version C steam trap joined the PowerDyne family, Charlotte, N.C.-based TLV Corp.’s line of thermodynamic steam traps. What’s distinctive about it is that it addresses a specific challenge found in copper tracing lines.

As the cognoscenti will already be aware, in process production, copper tubing is often used for the small bore, steam-bearing tracing lines used to maintain elevated temperatures in larger diameter pipe runs carrying viscous fluids. The practice is common in the food & beverage, refining and chemical industries. Over time, however, the inside diameter of the copper tubing erodes, with copper entering into the condensate solution, after which it can fall out and collect in steam traps, causing blockage. TLV, with the P21S version C, has simplified a steam trap’s discharge passageway, so that copper precipitate is carried out of the trap before it causes excessive trap blockage.

TLV’s solution includes the trap’s valve trim and Y-strainer design. The P21S version C also can be equipped with an optional blowdown valve.

The Breakthrough Products award-winning steam trap was originally developed by TLV for a client with special challenges when it came to copper-blocked steam traps, James R. Risko, TLV president, says, “But 80% of applications in refineries involve steam tracing and use of copper tubing is widespread in chemical processing. If there’s a copper leaching problem this is the steam trap for it.”

With a possible natural gas-driven North American manufacturing renaissance on the horizon, Risko is looking forward to what’s ahead for TLV. “Steam is here to stay. It remains the best available source of low-cost industrial heat. And TLV is about everything having to do with optimizing steam systems.”
