Description

Technical Field

[0001] This utility model relates to the field of fiberglass pipe technology, specifically to a fiberglass antistatic pipe. Background Technology

[0002] Fiberglass reinforced plastic (FRP) pipes are a new type of composite material made with resin as the matrix, glass fiber and its products as reinforcement, and silica sand as filler. They are corrosion-resistant, high-strength, long-lasting, and easy and reliable to install, and are widely used in industries such as petroleum, chemical, environmental protection, drainage, and agricultural irrigation. However, in flammable and explosive environments (such as petroleum and chemical industries) or when transporting materials prone to static electricity, ordinary FRP pipes, despite their strong insulation, easily accumulate static electricity, posing a safety hazard. Therefore, anti-static treatment is necessary for FRP pipes.

[0003] Existing methods typically involve coating the surface of fiberglass pipes with conductive coatings or adding conductive materials for antistatic treatment. However, simply coating the surface with conductive coatings is prone to wear and peeling, while uneven addition of conductive materials leads to unstable resistance, high cost, and complex processes. Therefore, we propose a fiberglass antistatic pipe. Utility Model Content

[0005] In view of the above and / or existing problems in fiberglass pipes, this utility model is proposed.

[0006] Therefore, the purpose of this utility model is to provide a fiberglass antistatic pipe. By using the antistatic functional layer as an independent and critical structural layer of the pipe wall instead of a surface coating, it is not easily damaged by wear and corrosion, has a long service life, and strong antistatic ability.

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] This utility model provides a fiberglass antistatic pipe. By treating the antistatic functional layer as an independent and critical structural layer of the pipe wall rather than a surface coating, it is less prone to failure due to wear and corrosion, has a long service life, and strong antistatic ability. At the same time, the antistatic functional layer is reliably electrically connected to the end flange to ensure effective discharge of static electricity, thereby ensuring the stable and reliable antistatic performance of the fiberglass pipe.

[0025] Figures 1-3 The diagram shown is a structural schematic of one embodiment of a fiberglass antistatic pipe according to this utility model. Please refer to [link / reference]. Figures 1-3 The fiberglass antistatic pipe of this embodiment includes a pipe wall 100 and a conductive connector 200 as its main body.

[0026] The pipe wall 100 is made of glass fiber reinforced resin matrix and includes, from the inside out, a corrosion-resistant inner lining layer 101, an antistatic functional layer 102, and a structural strength layer 103. Preferably, in this embodiment, the outermost layer of the pipe wall 100 is also provided with a wear-resistant protective layer 104, which provides wear protection for the outermost layer of the pipe wall 100.

[0027] Conductive connectors 200 are disposed at both ends of the pipe wall 100, and the antistatic functional layer 102 is reliably electrically connected to the conductive connectors 200 at both ends of the pipe wall 100. Preferably, in this embodiment, the conductive connector 200 is a metal flange, and the antistatic functional layer 102 is electrically connected to the metal flange via a pre-embedded metal conductive mesh or conductive adhesive at the pipe end. The conductive connector 200 with a metal flange facilitates the subsequent connection of multiple fiberglass pipes. The antistatic functional layer 102, reliably electrically connected to the end conductive connectors 200, ensures effective static electricity discharge. A positioning rod 201 is fixed to the outside of the conductive connector 200 at one end of the pipe wall 100, and a positioning rod 201 is opened on the outside of the conductive connector 200 at the other end of the pipe wall 100. The positioning groove 202 and the positioning rod 201 are inserted into the positioning groove 202. The positioning rod 201 and the positioning groove 202 are set on the outside of the conductive connector 200 to ensure that the conductive connectors 200 on the two pipes are aligned when connecting pipes, so as to facilitate the subsequent installation of bolts and nuts. A sealing ring 203 is set on the outside of the conductive connector 200. The sealing ring 203 is made of rubber. The sealing ring 203 plays a sealing role at the gap of the conductive connectors 200 of the two pipes, ensuring the airtightness when the two pipes are connected.

[0028] Combination Figures 1-3 The fiberglass antistatic pipe of this embodiment is used as follows: the antistatic functional layer 102, which is reliably electrically connected to the conductive connector 200, ensures effective discharge of static electricity, thereby making the antistatic performance of the fiberglass pipe stable and reliable. The antistatic functional layer 102 is an independent and key structural layer of the pipe wall 100 rather than a surface coating. It is not easily damaged by wear and corrosion during actual use and has a long service life. The wear-resistant protective layer 104 set on the outermost layer of the pipe wall 100 plays a role in wear protection. When connecting multiple fiberglass pipes, the positioning rod 201 and positioning groove 202 set on the outside of the metal flange ensure that the threaded holes on the metal flange are aligned so that they can be installed and fixed by bolts and nuts later.

In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
