Pipe and Valve Shielding
T-Flex® is the most versatile shielding material that NPO has to offer. Its ability to be poured as a liquid and cured as a flexible solid makes it ideal for fitting the maximum amount of shielding around a component while keeping space and weight to a minimum. The most common way this is put into practice it through pipe and valve shielding. NPO is able to conform the shielding snugly around a pipe and valve which brings the most shielding possible closest to the source while staying clear of any interferences in the immediate area. Below is a showcase of different pipe and valve shields NPO has made over the last few years.

Mold Making Capabilities
The flexible nature of T-Flex® not only applies to the material itself, but it’s ability to take any shape needed for a given application. With use of computer aided design software, NPO can create virtually any shaped shield as a plant would need it.

Steam Generator Hand Hole Shield
The NPO steam generator hand hole shield is a light weight T-Flex® Tungsten shield with captured screws fitted for existing bolt circle. A friction hinge allows door to remain partially open for instrumentation while keeping workers shielded.
