Description

Technical Field

[0001] This invention relates to the field of protective guidance, and in particular to a scratch-resistant and guiding device for the end of a small-diameter, seamless, bright, ultra-long heat exchange tube. Background Technology

[0002] Small-diameter seamless bright tubes have a high surface finish, but during transportation or assembly, the ends are prone to collisions with tools and tube sheets, resulting in scratches that affect the appearance and corrosion resistance; traditional plastic sleeves require additional adhesive, are easy to fall off, and have poor compatibility. Extra-long heat exchange tubes, with a single tube length of 8-12m, are prone to collisions and scratches at the ends during transportation and assembly, which can damage the glossy surface. Summary of the Invention

[0003] The purpose of this invention is to solve the existing technical problems by proposing a scratch-resistant and guiding device for the end of a small-diameter, seamless, bright, ultra-long heat exchange tube.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a small-diameter seamless bright ultra-long heat exchange tube end anti-scratch protection and guiding device, including a protective sleeve, which consists of an insert heat exchange tube end, a cylindrical section and a conical end. One side of the cylindrical section is connected to the insert heat exchange tube end, and the other side of the cylindrical section is connected to the conical end. The insert heat exchange tube end is interference-fitted with the inner wall of the corresponding heat exchange tube.

[0005] Furthermore, the heat exchange tube insertion end, the cylindrical section, and the conical end are provided with a communicating inner cavity, and the end face of the heat exchange tube insertion end is provided with an opening.

[0006] Furthermore, the heat exchange tube end, cylindrical section, and conical end are integrally formed.

[0007] Furthermore, the materials for the heat exchange tube ends, cylindrical sections, and conical ends are scratch-resistant nylon.

[0008] Furthermore, the tapered end has a cone angle of 30°.

[0009] Furthermore, air holes are opened on the conical end, and the air holes are connected to the inner cavity.

[0010] Furthermore, symmetrical air holes are opened on both sides of the conical end.

[0011] Furthermore, anti-slip textures are provided on the outer surface of the inserted heat exchange tube end.

[0012] Furthermore, the cylindrical section has a groove on the end face near the end of the heat exchange tube that is inserted into the groove.

[0013] The beneficial effects of this invention are: the integrated design of the heat exchange tube at both ends facilitates insertion of the heat exchange tube into the heat exchanger; the anti-slip texture design prevents slippage during assembly, and the end integrity rate after transportation is increased from 70% to 98%.

[0014] Vent design: Pressure balancing: During the operation of the heat exchanger, the fluid pressure inside and outside the tubes will change continuously; vents can keep the pressure inside and outside the protective sleeve balanced, avoiding the protective sleeve being squeezed, deformed or detached due to excessive pressure difference, thereby affecting the normal operation and protection effect of the heat exchanger tube bundle.

[0015] Preventing liquid buildup: Without vents, condensate or residual fluid may accumulate inside the protective sleeve when the equipment is shut down or the fluid flow changes. Vents allow the accumulated liquid to drain out, preventing corrosion and other problems caused by liquid buildup, and also preventing liquid buildup from affecting the heat transfer efficiency of the heat exchanger.

[0016] Ventilation and heat dissipation: When the heat exchanger is working, the heat of the internal fluid is transferred to the tube bundle. The vents facilitate air circulation, aid in heat dissipation, and prevent the protective sleeve from undergoing material property changes due to excessive temperature, thus affecting its protective function for the tube bundle.

[0017] Installation and Removal Assistance: When installing or removing the pipe end protective sleeve, the vents help air to enter and exit, reducing air resistance and making the installation and removal process of the protective sleeve smoother. Attached Figure Description
