T-Flex Blankets

NPO’s T-Flex® blankets are highly flexible non-lead shielding blankets with grommets located at the corners. These blankets come in the standard sizes shown in the table below. They are ASTM E-84 Class A rated.

T-Flex® blankets are more flexible and versatile than their lead counter parts, making them perfect for wrapping around a pipe or hanging from racks or scaffolding. Below are the sizes of T-Flex® blankets kept in stock. Other size available upon request, both in the standard lead wool blanket sizes and custom as well.

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.

Large Scale Pipe and Valve Shielding

The versatility of T-Flex® extends passed isolated valves, elbows, and short runs of piping. Some projects require extensive shielding across multiple pipe sizes and various valves and bends. The NPO engineering team uses a combination of plant drawings, laser scan data, picture references, and computer aided design software to create a completely custom, form fitting shielding package.

In plants like Perry and Davis-Besse, these huge installations have become permanent shielding and eliminated the need for blocking off high dose areas.

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 needs in order to fit around, cover, hold, or be inserted near whatever requires shielding.

Variety of Colors and Shapes

NPO can add a color layer to any tile. Different colors can help differentiate pieces in an assembly, act as a warning, or just make the shielding visually appealing.
