Profile: Dannenbaum LLC specializes in providing equipment for the oil and gas industries. We offer three main types of pipe expansion joints also known as piping expansion joints metal, rubber, and fabric. An expansion joint is installed in a pipe system for a couple of reasons. Firstly expansion joints can absorb vibrations and shock. Secondly expansion joints can also be used to relieve anchor stress, reduce noise, and compensate for misalignment. Our pipe expansion joints are made of metal, fabric, or an elastomer (rubber). Expansion joints are also designed for other criteria, such as noise absorption, anti vibration, earthquake movement, and building settlement.
