AI Technical Summary

Benefits of technology

The patent describes a swivel that can connect directly or indirectly between a hydrant manifold and a industrial water supply pipe system. The preferred embodiments show a simple and direct connection. The technical effect of this swivel is the ability to create a secure and reliable connection between two pipes, which can help to prevent leaks and reduce the risk of contamination during industrial water supply operations.

Problems solved by technology

Fire field logistics present problems that rank nearly as high as equipment-on-hand problems and personnel-available problems when facing an industrial fire fighting response.

Large diameter hose is expensive.

However, a duplication of iron and of header equipment is then required.

Although the industrial fire fighting industry has historically tolerated the waste of hose and duplication of hydrants associated with fixed hydrant manifolds, with the increased diameter requirements for the supply pipes and hoses, the cost of the waste has risen.

A swiveled hydrant manifold saves the cost of providing multiple manifolds facing different directions and / or of providing a hundred or more extra feet of hose required to redirect water without undue pressure loss.
