TTPS Tuff Tube Purgeless Sleeve is an innovative solution designed for tube-to-tube tie

● Enhanced Durability: TTPS sleeve is typically a minimum 1.5 times thicker than

the original tube wall, ensuring a robust and long-lasting connection.

● No Purging Required: Unlike conventional tube repairs or stub header installations,

TTPS eliminates the need for tube purging, even with high-performance alloys such as

P22 (2.25% Chrome), P91 (9% Chrome), and 1% Molybdenum.

● Preheat Efficiency: Welding on high-alloy materials requires preheating up to 450°F.

The self-fitting capabilities of TTPS ensures the contractor does not place any cold tacks

on the fit- up prior to preheating such as conventional tube butt welds (CJP) Complete

Joint Penetration.

● Simplified Welding Process: Compared to conventional butt welds, TTPS utilizes a lap

joint weld, which is easier to execute and reduces the risk of welding defects. This is

especially beneficial in HRSG and boiler tube applications, where thin tube walls (as

small as .105”) make butt welding highly challenging.

● Self-Aligning Fit-Up: TTPS eliminates the difficulties of aligning thin tube edges. The

quick fit-up process takes less than a minute, allowing for rapid preheat application

without the need for tack welds before full heating.

● Eliminates Purging Hassles: Forget about using rice paper, bread, or biscuit dough as

temporary purge dam solutions. TTPS removes the risk of oxidation and "sugaring,"

ensuring a clean and dependable weld every time.

Boost Productivity & Reduce Costs

With TTPS, welders can avoid complex mirror welding, intricate torch positioning, and purge

chamber contamination. The simplified fit-up process and reduced fit-up time translate to

significant savings in labor and materials, making it the smart choice for boiler tube repairs.

Upgrade your welding process with TTPS — Tuff Tube Purgeless Sleeve that delivers

strength, efficiency, and reliability without the complications of traditional butt welds.
