Rigid copper pipe is typically joined by soldering — using an open-flame torch in tight spaces next to wood framing — so replacing damaged pipe sections can be perilous. Unless, that is, you use a ...

Materials with negative linear compressibility are sought for various technological applications. Such effects were reported mainly in framework materials. When heated, they typically contract in the ...

Abstract: The surface of PVC plastic was treated by coupling agent before chemical plating, in order to substitute chromic acid due to its toxicity to environment and human beings. Three kinds of ...

Reduces installation time for joining rigid PVC conduit subject to movement Five times faster to install Accommodates axial or parallel deflection of up to ¾ in. T&B Fittings nonmetallic ...

Abstract: This paper presents the design of a controlled trajectory rapid compression and expansion machine (CT-RCEM) that offers the unique capability of real-time piston trajectory control. While in ...
