Special tube bending equipment is used to bend the conduit without kinking or denting it. Bronze is somewhat more resistant to denting than aluminum. Because it fills the pores, linseed oil partially protects wood from denting by compression. PVC also permits more rough treatment, as the plastic instrument can be bumped without denting. Four bombs were dropped one hitting and denting "Rochester's" crane but not exploding. Other officers grabbed the phone from Antonissen and threw her against the truck, denting it. The injury occurred on her favorite jump, the lutz, denting her confidence. In 2018, a tugboat dropped its anchor on the pipeline near Michigan, denting the pipe. Ouvrage Denting is a lesser work ("petit ouvrage") of the Maginot Line. Denting is privately owned, and is in relatively good condition. Denting remained under Army control until after 1971, when it was declassified and sold.
