Industrial pressure-resistant polypropylene pipe fittings

Abstract

This utility model relates to the field of industrial production technology and proposes an industrial pressure-resistant polypropylene pipe fitting. The fitting includes a pipe body comprising an inner pipe and an outer pipe, with a fiberglass mesh disposed between them. The inner pipe, outer pipe, and fiberglass mesh are connected by hot-melt bonding. The inner pipe, outer pipe, and fiberglass mesh are integrally formed by heated extrusion. This device, through hot-melt bonding and heated extrusion integral forming processes, tightly integrates the inner pipe, outer pipe, and intermediate fiberglass mesh, significantly enhancing the overall integrity and structural stability of the fitting body. It improves pressure resistance from the internal structure, adapting to the pressure environment of industrial fluid transportation. Simultaneously, the staggered anti-compression ribs on the outer pipe effectively disperse external stress, significantly strengthening the outer pipe structure, reducing the risk of deformation and damage under pressure and impact, and extending service life.

Description

Technical Field

[0001] This utility model relates to the field of industrial production technology, specifically to industrial pressure-resistant polypropylene pipe fittings. Background Technology

[0002] In industrial production, fluid transport systems, as a core component, place extremely stringent requirements on the performance of pipe fittings. Especially in industries such as chemical, petroleum, and metallurgy, the transported media often exhibit characteristics such as high pressure, high temperature, and strong corrosiveness. This necessitates pipe fittings possessing excellent pressure resistance, structural stability, and service life to ensure the safe and efficient operation of the entire transport system.

[0003] However, traditional industrial polypropylene pipe fittings have gradually revealed many problems during long-term use. Conventional single-structure polypropylene pipe fittings, due to limitations in their material properties and molding processes, have relatively insufficient overall structural strength. Under high-pressure fluid transportation environments, they are prone to rupture and leakage due to excessive internal pressure, which not only affects normal production but may also lead to safety accidents.

[0004] Meanwhile, in the external environment, pipe fittings are inevitably subjected to external forces such as compression and collision. Traditional pipe fittings lack effective pressure-resistant structural design, and external stress cannot be properly distributed, which can easily lead to deformation or even damage of the pipe fittings, greatly shortening their service life and increasing the maintenance costs and equipment replacement frequency for enterprises.

[0014] (III) Beneficial Effects

[0015] In summary, this utility model has at least one of the following beneficial technical effects:

[0016] This industrial pressure-resistant polypropylene pipe fitting utilizes a device that integrates the fiberglass mesh between the inner and outer pipes through hot-melt bonding and heated extrusion, resulting in a tight bond between the three components. This significantly enhances the overall integrity and structural stability of the pipe fitting, improving its pressure resistance from an internal structural perspective. It better adapts to the pressure environment of fluid transport in industrial settings. Simultaneously, the staggered anti-pressure ribs on the outer pipe effectively disperse stress from external pressure, significantly improving the structural strength of the outer pipe and reducing the risk of deformation or damage under external pressure or impact, thus extending the pipe fitting's service life.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-3Industrial pressure-resistant polypropylene pipe fittings include a pipe fitting body 1, which includes an inner pipe 2 and an outer pipe 3. A fiberglass mesh 4 is provided between the inner pipe 2 and the outer pipe 3. The inner pipe 2, the outer pipe 3, and the fiberglass mesh 4 are connected by heat fusion. The heat fusion connection can tightly combine the inner pipe 2, the outer pipe 3, and the fiberglass mesh 4, enhance the integrity and structural stability of the pipe fitting body 1, and improve the pressure resistance.

[0024] It should also be noted that the inner tube 2, outer tube 3, and fiberglass mesh 4 are integrally formed by hot extrusion. This hot extrusion integral forming method can further ensure the tightness of the joint between the parts, reduce the connection gaps, improve the overall strength and pressure resistance of the pipe body 1, and at the same time simplify the production process and improve production efficiency. The outer tube 3 is provided with staggered anti-compression ribs 5, which can effectively enhance the structural strength of the outer tube 3, improve the extrusion resistance of the pipe body 1, and disperse stress when subjected to external pressure, reducing the risk of deformation or damage to the pipe body 1. Both ends of the pipe body 1 are fixedly connected with flanges 6, which facilitates the connection of the pipe body 1 with other components. The connection of pipes or equipment is simple and reliable, ensuring the sealing and stability of the connection. A reinforcing ring 7 is provided at the connection between flange 6 and pipe body 1. The reinforcing ring 7 is integrally formed with pipe body 1 and flange 6, which can enhance the structural strength of the connection between flange 6 and pipe body 1, prevent the connection from breaking or being damaged due to excessive force, and improve the overall durability of pipe body 1. Multiple connection holes 8 are provided on flange 6. The multiple connection holes 8 make the connection between flange 6 and other components more stable. The appropriate connection position can be selected according to actual needs to ensure the reliability and sealing of the connection.

[0025] In summary, the working principle and process of this industrial pressure-resistant polypropylene pipe fitting are as follows: First, place the industrial pressure-resistant polypropylene pipe fitting in the required position according to the installation path. Then, adjust the angle of the pipe fitting body 1 so that the connection holes 8 of the flanges 6 at both ends are aligned with the flange holes 6 of the pipe to be connected, ensuring accurate connection. If multiple pipe sections are involved in the splicing, the positioning of each section must be completed sequentially to ensure that the overall pipeline route meets the design requirements. Then, place a sealing gasket between the two connecting flanges 6, pass bolts through the connection holes 8 of the flanges 6, and pre-tighten with nuts. During pre-tightening, tighten the bolts diagonally, and then gradually tighten all bolts until the specified torque is reached.

[0026] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
