AI Technical Summary
The outer wall of traditional plastic water supply and drainage pipes is too smooth, resulting in low adhesion, poor wrapping, easy to detube, and small heat dissipation surface, which affects the installation and backfill effect.
The plastic outer striped water supply and drainage pipe is designed. By setting longitudinal or transverse trapezoidal stripes on the outer wall of the circular annular pipe, the adhesion and wrapping of the pipe and the wall are increased, and the contact heat dissipation area with the ground backfill is increased through the stripe design. .
It effectively improves the adhesion and wrapping between the pipe and the wall, prevents detubes, and controls the retraction problems caused by thermal expansion and contraction by increasing the heat dissipation area.

Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of water supply and drainage pipes, in particular to a plastic outer stripe water supply and drainage pipe. Background Art
[0002] Since the country proposed the policy of replacing steel with plastic in the early 1990s, plastic water supply and drainage pipes (such as pp-r pipes, pE-RT, pE, and other plastic pipes) have been widely used in civil buildings, industrial and commercial buildings, and decoration fields.
[0003] Since the outer walls of traditional plastic pipes are relatively smooth and glossy, the adhesion to the wall filler is low and the wrapping is not strong when the building water heating pipes are installed, buried or grooved for decoration. When installing, laying and backfilling the low-temperature auxiliary floor heating pipes, there are disadvantages such as the outer wall of the pipe is too smooth, which makes it easy to detach the pipe from the manifold, the smooth surface has a small heat dissipation surface and slow heat dissipation, and the smooth surface has poor wrapping and adhesion with the backfill. Utility Model Content
[0004] In view of the above problems, the utility model provides a plastic outer striped water supply and drainage pipe, including a circular pipe, and a plurality of stripes arranged on the outer wall of the circular pipe, the stripes are arranged horizontally or vertically on the outer wall of the circular pipe, the stripe height is 0.3-5mm, the intervals between the stripes are the same or different, the stripe cross-section is trapezoidal, and the stripes are discontinuous; the utility model solves the drawbacks of traditional plastic water supply and drainage pipes, and increases the adhesion and wrapping of the pipe and the wall by designing the outer wall structure of the plastic water supply and drainage pipe with longitudinal stripes, and also solves the problem of the pull-out and anti-detachment of the pipe between the pipe and the connector, and increases the contact and heat dissipation area between the pipe and the ground backfill through the longitudinal stripe design.
[0005] The technical solution of the utility model is as follows: a plastic outer stripe water supply and drainage pipe comprises: a circular ring-shaped pipe and a plurality of stripes arranged on the outer wall of the circular ring-shaped pipe.
[0006] Furthermore, the stripes are arranged transversely on the outer wall of the annular pipe.
[0007] Furthermore, the stripes are longitudinally arranged on the outer wall of the annular pipe.
[0008] Furthermore, the intervals between the stripes are the same.
[0009] Furthermore, the intervals between the stripes are different.
[0010] Furthermore, the stripe height is 0.3-5 mm.
[0011] Furthermore, the cross section of the stripe is a trapezoid.
[0012] Furthermore, the stripes are discontinuous.
[0013] Furthermore, reinforcing ribs are provided on the outer wall of the annular pipe.
[0014] The beneficial effects of the utility model are:
[0015] It solves the drawbacks of traditional plastic water supply and drainage pipes. The adhesion and wrapping properties of the pipes and walls are increased by designing horizontal and vertical stripes on the outer wall structure of the plastic water supply and drainage pipes. At the same time, the problem of the pipes and connectors being resistant to pulling and detaching is also solved. The contact and heat dissipation area between the pipes and the ground backfill is increased by designing horizontal and vertical stripes, effectively controlling the longitudinal shrinkage and creep problems caused by thermal expansion and contraction of plastic pipes.
