Embodiment Construction
[0034] Specific embodiments of the present invention, such as figure 1 As shown, a self-flange type steel mesh reinforced plastic pressure pipe 1 includes a pipe wall 4, a steel mesh 3 is sandwiched in the pipe wall 4, and integrally formed flanges 2 are arranged at both ends of the pipe, and at least one end of the pipe is There is an annular groove on the flange 2. The flange 2 is used to connect the pipe ends during construction, and the annular groove is used to place a sealing ring to seal the connection. The flange 2 is used to connect, which not only ensures the connection strength but also makes the connection process faster.
[0035] A method of manufacturing self-flange steel mesh reinforced plastic pressure pipe of the present invention, comprising the following steps:
[0036] Wrap plastic tape 5 on the outer wall of the inner mold, and wrap steel mesh 3 outside the plastic belt 5, wherein the outer wall of the inner mold 8 has the same shape as the inner wall of...

The invention discloses a self-flanged steel mesh-reinforced plastic pressure pipe, comprising a pipe wall and a steel mesh sandwiched inside the pipe wall, and characterized in that: two ends of the pipe are provided with integrally-formed flanges and the flange at one end at least is provided with an annular groove. The invention has the beneficial effect that: the integrally-formed flanges arranged at two ends of the pipe and the sealing-ring-embedded annular groove arranged on the flange at one end facilitate pipeline construction connection; and production cost can be remarkably saved byheating up with flame during the manufacturing.
Description
technical field [0001] The invention relates to a plastic pipe and a manufacturing method thereof, in particular to a self-flange type steel mesh reinforced plastic pressure pipe and a manufacturing method thereof. Background technique [0002] Steel mesh reinforced plastic pressure pipe refers to the pipe reinforced with steel mesh in the plastic pipe wall, which is usually used as a large diameter pressure pipe. The existing plastic processing methods can be referred to for the manufacture of steel mesh reinforced plastic pressure pipes. The existing plastic processing methods mainly include the following four types: extrusion molding, injection molding, blow molding and rotational molding. [0003] Extrusion molding is continuous molding, suitable for making pipes, profiles, sheets, etc. The mold is stationary during extrusion molding, and its disadvantages are that it is not suitable for manufacturing large-diameter pipes, and cannot form integrally formed flanges at th...
