Critical Technical Advantages
-
Exceptional Mechanical Strength: Drilled and machined from solid round barstock with root diameters ranging from 9 to 50 mm, the TT151 is engineered to withstand extreme process pressures up to 500 bar (7,252 psi).
-
iTHERM TwistWell Technology: Available in a unique helical design, the TwistWell option effectively breaks up vortex shedding. This significantly reduces vortex-induced vibrations (VIV) in high-velocity applications, often eliminating the need for support collars or shortened immersion lengths.
-
Standardized and Custom Compliance: Whether your facility follows DIN 43772, ASME B40.9, or NAMUR NE 170 norms, the TT151 can be configured to meet these specific dimensional and material requirements, ensuring a “drop-in” fit for existing infrastructure.
-
Versatile Tip Geometry: To optimize the balance between mechanical strength and thermal response time, tips are available in straight, tapered, or stepped configurations.
-
Wide Material Selection: To combat chemical stress, the TT151 is available in a broad array of materials, from standard 316L stainless steel to high-performance alloys like Alloy C276 or Monel, ensuring compatibility with corrosive or toxic media.
-
Flexible Installation: The modular design supports a vast selection of process connections, including various thread sizes, standard flanges (ANSI/ASME, EN/DIN), and weld-in versions for permanent installations.
