Problems solved by technology
Its disadvantages: first, the connection is unreliable, construction is difficult, and production efficiency is low; second, the plastic layer on the surface of the section steel will separate from the steel strip, which will cause the steel strip to corrode
Disadvantages: low ring steel, large investment in equipment and difficult to enlarge the pipe diameter
Its disadvantages: the product cost is high and unbearable; the electric heating fuse is easy to fall off during construction, making it difficult to guarantee the construction quality

Embodiment 1
[0018] Example 1: refer to the attached figure 1 An electrofusion socket type glass fiber reinforced drainage pipe comprises a socket, a socket, a spiral reinforcing rib and a spiral heating wire.
Embodiment 2
[0019] Example 2: On the basis of Example 1, first mix plastic and glass fiber, extrude a ribbon-shaped plastic tape containing glass fiber and wrap it on a rotating cylindrical high-temperature mold, and continuously wrap it to make it welded into a A whole. At the same time, the mold at the other outlet of the extruder extrudes a tubular glass fiber-containing plastic pipe, and a PP liner is sleeved in the glass fiber plastic pipe, so that it is simultaneously wound with the glass fiber-containing plastic tape extruded before. On a high temperature mold, the glass fiber-containing plastic tube and the glass fiber-containing plastic tape are bonded together. Continuous production, helical reinforcing ribs are formed on the outside of the electrofusion socket-type glass fiber reinforced drainage pipe. The reinforcing ribs are distributed in the middle 98% of the pipe, and its two ends are the socket and socket without reinforcing ribs. After cooling and setting, the socket en...

The invention relates to an electrically melted socket-type fiber glass reinforced plastic drain pipe and a manufacturing method thereof. The electrically melted socket-type fiber glass reinforced plastic drain pipe not only has the characteristics of a plastic pipe, but also has the characteristic of high ring stiffness of a metal pipe. The electrically melted socket-type fiber glass reinforced plastic drain pipe has the advantages that: 1) compared with similar plastic pipes, the pipe has the characteristic that 30 percent of polyethylene (PE) materials are saved; 2) the pipe is convenient to connect, only 1000RMB is required to be invested in connecting equipment and the connection of one pipe can be completed within 17 minutes; 3) the connection reliability is high and the goal of 100 percent of no leakage is achieved; 4) the cost is low and is 30 percent of the plastic pipe with the same performance and the service life and anticorrosive property are more than five times of the service life and anticorrosive property of cement pipes; 5) since an electric heating fuse is embedded in the pipe wall, the electric heating fuse does not fall off during socket construction; 6) the pipe can adapt to severe construction conditions and the excavated volume for construction is small; 7) the ring stiffness of the pipe is high and the amount of used materials is small; and 8) since the pipe is made of plastics and glass fibers, the pipe is not corroded by sewage.
Description
technical field [0001] The invention relates to a glass fiber reinforced plastic pipe with a structural wall, which belongs to the field of manufacturing drainage pipes. Background technique [0002] The steel strip reinforced pipe adopts steel plate as the inner layer in the structural design, so as to improve the ring stiffness of the intake and drain pipes. Its shortcomings: First, the connection is unreliable, the construction is difficult, and the production efficiency is low; second, the plastic layer on the surface of the profiled steel will be separated from the steel strip, causing the steel strip to corrode. [0003] Double-wall corrugated pipe adopts PE plastic molding structural wall pipe to improve its ring rigidity. Disadvantages: The ring stiffness is low, the equipment investment is large and the diameter of the pipe is not easy to enlarge. [0004] Carat pipe, in the structural design, is reinforced with PE hollow pipe, so as to improve the rigidity of the...
