Welding plastic is a critically important part of everyday engineering—especially for preventing leaks in underground water and gas pipes. For decades, engineers have understood that a properly welded ...

Polyethylene pipe welding strength now has a molecular explanation: a Physical Review Letters study published August 2026 uses large-scale molecular dynamics simulations to show that HDPE pipe joints ...

PVC pipe is commonly used as electrical conduit as well as irrigation piping. It's rigid and strong, which doesn't allow it to bend at all. Elbows and couplings make it possible to manipulate the path ...
