The connection of the steel spiral corrugated pipe is generally connected by a flared interface to an internal expansion interface and a double hot melt interface.
1. Flared interface structure
The purpose of the flared interface PE pipe is to use malleable cast iron or ductile iron as the main material. It is composed of a liner body (bushing), a nut or bolt, a threaded ring or a flared flange and a sealing rubber ring. The nut is tightened or the blue is pressed to make the pipe shrink, and the inner surface of the pipe and the sealing rubber ring on the inner pipe body form a metal pipe connection of the oblique side sealing connection.
Steel-plastic composite pipe
2. The mechanical connection of the internal expansion interface is made of malleable iron or ductile iron. It consists of pipe body, nut or bolt, expansion flange or expansion thread ring, expansion ring and sealing rubber ring. The expansion and expansion mouth pressure blue or the expansion thread ring and the expansion ring snap ring are integrated into one body, and the end face of the pipe and the end face of the pipe or the end face of the pipe and the end face of the pipe are formed by fastening the nut or pressing the blue. Sealed metal fittings.
Steel-plastic composite pressure pipe
3. Double hot melt interface structure
The double hot-melt interface connection is to insert the steel-plastic tube into the tube body after the plastic layer inside and outside the steel-plastic tube and the tube body and the socket surface are respectively melted and melted, and then the molten surface is pressed together, and the polymer molecules are Under the action of heat and pressure, they are intertwined and coiled to produce van der Waals force, and the connection form of the welding surface is formed after cooling.
