Sweco Fab, Inc., a division of PT&P, fabricated a variety of six spectacle blinds that will be used for selective line isolation. The spectacle blinds are fabricated from A516-70 carbon steel with sizes ranging from 4″ to 14″ diameter and per ASME B16.48 code. The function of a spectacle blind is to allow a line to be in either full shut-off mode or full flow mode, depending on which side is being utilized. Spectacle blinds are a lower cost alternative to double block and bleed valves where OSHA requires positive isolation of piping segments for safety reasons.

PT&P designed and fabricated a full coverage bulletproof shield for a company in Texas. This critical defense product is cost-effective, easy to move, compact to store, and convenient to access at a moment’s notice. Each unit includes slots in order to store four bulletproof riot shields. We hope the need never arises; however, this safety product is suited for public spaces such as schools, churches, concerts, public events, government agencies, and functions. The shield can function as a cover for a doorway, providing safety to inhabitants while also allowing for mobility, enabling persons to exit safely from an unforeseen situation. The key design considerations this shield sought to address were the safety of the defense personnel by providing for head-to-toe protection, but also enabling mobility during one-on-one incidents.

In addition to our deep technical expertise in the design and manufacturing of supports and expansion joints for piping systems, we have always been able to pivot to build what is the task in the moment by our customers and community. The bulletproof shield showcases our ability to be flexible, think outside of the box, and solve most problems.

Some of our key products, such as the big ton, are a product of this kind of exchange with our customers. We invite you to take a look at your project needs and our scale and capabilities, and ask what we can do for you.
