Hanging pipelines, such as those used in chemical plants, on pipe bridges, tank farms etc. are fixed with steel U-bolts.
To date, the metal pipes are mounted with direct contact using pipe bracket made of metal. Since all piping have a certain inherent movement due to temperature fluctuations or vibration, the corrosion protection and in some cases even the pipes will be damaged at the point contacts. Therefore repairs are needed after a short time.
In the chemical industry, many pipelines are laid outdoors. Therefore supports are needed, where the pipes are laid or on which they hang. In both cases, the pipe must be fixed using pipe brackets.
The patented pipe bracket has a liner that is installed between pipe and pipe bracket to avoid direct contact between both. This pipe bracket liner has a groove to ensure a perfect fitting with the pipe bracket. The pipe bracket liner is as long as the tubular bracket and it is wider than the tubular bracket. The pipe bracket liner is made of a plastic, wherein the plastic is polyethylene.
Furthermore the tubular bracket is threaded on both ends and has a backstop on each side. When the nut is tightened, the backstop abuts the counter support. The backstop in conjunction with the plate limits the path when tightening the nuts, that the pipe cannot be squeezed.
In 2010, the patent has been issued for the PE steel pipe bracket.
