Laryngeal hoop features: worm friction is small, especially suitable for high-grade models or anticorrosive material parts of the connection. Throat hoop has a wide range of application, torsion and pressure resistance, throat hoop torsion torque balance, with a firm lock, but also very tight, large adjustment range, throat hoop is suitable for 30mm above the fastener of soft and hard pipe connection, the appearance of the assembled throat hoop looks particularly beautiful.

For the connection process of the throat hoop, the steel pipe should be cut by the steel pipe cutting machine according to the required length. The incision should be smooth, and the end face of the incision should be perpendicular to the axis of the steel pipe. If there are burrs on the incision, use sandpaper, file or grinder to polish. It is recommended to use the pipe knife of the sleeve machine to break the pipe. Its advantage is that the end face of the pipe is vertical and flat, and there are few burrs. When the conventional toothless saw breaks the pipe, it is easy to cause the dislocation and burr of the pipe section due to the uneven end face of the saw blade when leaving the factory, excessive force, pipeline rotation and other factors.
