The initial cost of throat hoop connection is 20-30% lower than that of flange connection, the service life of clamp is longer than that of flange connection, and the installation and maintenance are simple and fast, and its economic and technological advantages are obvious. Especially after the development in recent years, the production technology of throat hoop connector in China has been greatly improved. However, due to the influence of the traditional concept for many years, the clamp or the lack of understanding of the engineering which has been used and achieved good results at home and abroad, some project managers in most areas of the clamp are not very receptive to this new type of connector.

Notes on selection of hose hoop connector

1. There are two kinds of throat hoop connectors: forged steel and nodular cast, which have different pressure resistance. Reasonable selection should be made according to the actual needs of the project.

2. The ellipticity of the hose hoop, the fire resistance of the sealing ring and the corrosion resistance of the screw should be strictly inspected when inspecting the throat hoop connector.
