We do not know that in the development of fasteners, there is often a kind of fastener at the connection of hard and soft pipes, which is the so-called throat hoop. In our prior art, the throat hoop is easy to appear dead angle when it is used for the connection of small-diameter soft and hard pipes,

In the prior art, when the throat hoop is used for the connection of small-diameter soft and hard pipes, the dead angle will appear, resulting in the leakage of liquid and gas. The throat hoop adopts an open inner and outer ring structure and is fastened with bolts. The hose hoop can effectively solve the problems of dead angle and leakage of liquid and gas in the connection of small-diameter soft and hard pipes. The simple structure and easy manufacturing cost are 30% of the original product. The hose hoop is widely used in motor vehicles, petrochemical, pharmaceutical, food brewing sewage treatment, purification, dedusting, steam car accessories and other machine accessories.

       Features of throat hoop: small friction of worm, especially suitable for the connection of high-grade models or anti-corrosion materials. The scope of application of the throat hoop is very wide, it is resistant to torsion and pressure, the torque of the throat hoop is balanced, it has firm locking, and it is very tight, and the adjustment range is large. The throat hoop is suitable for the fasteners connected by more than 30mm soft and hard pipes, and the assembled throat hoop looks particularly beautiful outside.

       For the connection process of stainless steel throat hoop, the steel pipe shall be cut by the steel pipe cutter according to the required length, the cut shall be flat, and the end face of the cut shall be vertical to the steel pipe axis. If there is burr at the incision, it shall be sanded with sandpaper, file or grinder. It is suggested to use the pipe cutter of the threading machine to break the pipe, which has the advantages of vertical flatness of the end face of the pipe and few burrs. When the conventional toothless saw breaks the pipe, it is easy to cause the dislocation of the pipe section and many burrs due to the factors such as the uneven end face of the saw blade, excessive force, pipe rotation and so on.
