Problems solved by technology

[0008] To sum up, the current plastic pipes have the following problems: the external insulation pipes made of thermal insulation materials externally applied to the plastic pipes have a short service life and poor long-term use effect; the cost of thick-walled plastic pipes with high ring stiffness and large diameter is too high Low market acceptance, serious waste of resources, and the outer winding metal belt is easily delaminated and separated, causing accidents

Embodiment 1

[0022] A hollow-walled continuous fiber prepreg tape winding pipe, including a tubular pipe body 1, a continuous fiber reinforced bearing layer 2, a protective surface layer 4 and support ribs 5, such as figure 1 As shown, the specific structure is:

[0023] The pipe body 1 serves as the inner stress conduction layer;

[0024] The continuous fiber reinforced bearing layer 2 is pasted on the outer wall of the pipe body 1, and the protective surface layer 4 is sleeved outside the continuous fiber reinforced bearing layer 2, and a hollow space is formed between the continuous fiber reinforced bearing layer 2 and the protective surface layer 4. The wall layer 3, the outer wall of the continuous fiber reinforced bearing layer 2 and the inner wall of the protective surface layer 4 are connected by seven supporting ribs 5, and the supporting ribs 5 are evenly distributed around the continuous fiber reinforced bearing layer 2.

[0025] In this embodiment: the pipe body 1 and the cont...

Embodiment 2

[0028] A hollow-walled continuous fiber prepreg tape winding pipe, including a tubular pipe body 1, a continuous fiber reinforced bearing layer 2, a protective surface layer 4 and support ribs 5, such as figure 1 As shown, the specific structure is: the hollow wall layer 3 is evacuated, and the two ends of the mesoporous wall layer 3 are closed with heat-insulating materials. Other structures are all the same as in Embodiment 1.

[0029] When the present embodiment is used, after the hollow wall layer 3 is evacuated and sealed with insulating materials at both ends, it can become a vacuum insulation pipe, which greatly reduces the thermal conductivity of the pipe. Other usage methods are all the same as embodiment 1.

Embodiment 3

[0031] A hollow-walled continuous fiber prepreg tape winding pipe, including a tubular pipe body 1, a continuous fiber reinforced bearing layer 2, a protective surface layer 4 and support ribs 5, such as figure 2 As shown, the specific structure is: the supporting rib 5 is W-shaped. Other structures are all the same as Embodiment 2.

[0032] When the present embodiment is used, after the hollow wall layer 3 is evacuated and sealed with insulating materials at both ends, it can become a vacuum insulation pipe, which greatly reduces the thermal conductivity of the pipe. Other usage methods are all the same as embodiment 1.

Abstract

The invention relates to the field of lined or sheathed plastic molding or connection, in particular to a continuous fiber prepreg tape winding pipe with hollow walls. The continuous fiber prepreg tape winding pipe with the hollow walls comprises a tubular pipe body (1) and is characterized by further comprising a continuous fiber reinforced supporting layer (2), a protection surface layer (4) andsupporting ribs (5). The continuous fiber reinforced supporting layer (2) is attatched to the outer side wall of the pipe body (1), the protection surface layer (4) is arranged outside the continuousfiber reinforced supporting layer (2) in a sleeving mode, and a hollow wall layer (3) is formed between the continuous fiber reinforced supporting layer (2) and the protection surface layer (4), theouter side wall of the continuous fiber reinforced supporting layer (2) is connected with the inner side wall of the protection surface layer (4) through at least three supporting ribs (5), and the supporting ribs (5) are uniformly distributed around the continuous fiber reinforced supporting layer (2). The continuous fiber prepreg tape winding pipe is good in uniformity, long in service life, high in thermal insulation property and high in mechanical strength.

Description

technical field [0001] The invention relates to the field of plastic molding or connection of lining or sheathing, in particular to a hollow wall continuous fiber prepreg tape winding pipe. Background technique [0002] The thermoplastic prepreg tape reinforced composite pipe has the remarkable characteristics of high strength, thin wall, light weight, and long life. Both rigid and soft, at the same time, the pipe can be customized according to the user's different pressure performance 0.6Mpa ~ 30MPa and special functions (such as wear resistance, electrical conductivity, heat conduction, heat preservation, rigidity enhancement), etc. Compared with the same pressure performance High-quality plastic pipes can save more than 60% of materials on average, which is the development direction of plastic composite pipes in the future. [0003] Today's pipe insulation technology is to lay low thermal conductivity insulation materials outside the pipe to achieve heat preservation and...
