Description

Technical Field

[0001] This invention relates to the field of pipeline protection technology, and in particular to safety protection devices for chemical pipelines. Background Technology

[0002] Chemical pipelines are essential equipment used in chemical production to transport various fluids (such as gases, liquids, and slurries), and are widely used in industries such as petroleum, chemicals, pharmaceuticals, and food. The design, material selection, installation, and maintenance of chemical pipelines are crucial to the safety and efficiency of production.

[0003] In chemical production, targeted protective measures are required for chemical pipelines, such as anti-static, leak prevention, insulation, and physical protection. Current protective measures mostly involve spraying paint on the pipeline surface; further improvements may include wrapping the surface with tape or insulation materials. Overall, the protection solutions are relatively simple. Summary of the Invention

[0004] To address the aforementioned problems, this invention discloses a safety protection device for chemical pipelines, comprising: a second aluminum foil tape wrapped around the pipeline; two clamping members fitted onto the outer side of the second aluminum foil tape, forming a tubular structure; and a foamed layer filling the space between the second aluminum foil tape and the clamping members. The foamed layer on the sidewall of the pipeline provides insulation and protection, while the foaming process ensures that the foamed material completely fills the interior of the clamping members.

[0005] The outer side of the clamping component is covered with a rock wool layer, and a first aluminum foil tape is wrapped around the outer side of the rock wool layer. The rock wool layer provides a fireproof effect.

[0006] Preferably, one side of the clamping component has several through holes, and the other side has a second threaded hole. A first bolt is inserted through the through holes, and the first bolt engages with the second threaded hole, with its end abutting against the second aluminum foil tape. The first bolt not only connects the two clamping components together, but also ensures that the axis of the foam layer and the axis of the pipe are collinear, meaning the foam layer has a consistent thickness on the sidewall of the pipe.

[0007] Preferably, the clamping member has a plurality of first threaded holes in its middle portion. Some of the first threaded holes serve as injection ports for foaming material.

[0008] Preferably, a second bolt is threaded into the first threaded hole, and the end of the second bolt abuts against the second aluminum foil tape. The second bolt, in conjunction with the first bolt, ensures that the pipe fitting and pipeline composed of the two clamping parts are arranged coaxially.

[0009] Preferably, the end of the retaining member is provided with two plugs, and the two plugs are fitted together on the pipe. The plugs seal one end of the retaining member, which facilitates the construction of the foam layer.

[0010] Preferably, the end of the plug is provided with a side lug, and a third bolt is inserted through the side lug, with a nut threaded onto the third bolt. The two plugs are fixedly connected by the third bolt and the nut, thus clamping them onto the pipe.

[0011] The beneficial effects of this invention are as follows:

[0012] 1. It is equipped with a foam layer and a rock wool layer, along with a clamping component, which provides the pipeline with thermal insulation, fire protection, and physical impact protection.

[0013] 2. The foam layer is obtained by foaming inside the cohesive component, so that the foam layer can fully fill the interior of the cohesive component.

[0014] 3. A second aluminum foil tape is provided, the smooth surface of which facilitates the cleaning of the foam layer.

[0015] 4. The first aluminum foil tape provides a certain degree of anti-static effect. Attached Figure Description

[0022] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0023] like Figures 1 to 4 As shown, a safety protection device for chemical pipelines includes a second aluminum foil tape 6 wrapped around the pipeline. A smooth sidewall is achieved by pre-winding a layer of the second aluminum foil tape 6 around the pipeline. Two clamping members 4 are fitted onto the outer side of the second aluminum foil tape 6, forming a tubular structure. A foam layer 5 is filled between the second aluminum foil tape 6 and the clamping members 4. After the clamping members 4 are installed, foam material is injected between the clamping members 4 and the second aluminum foil tape 6. This method completely fills the space between them. The foam layer 5 provides insulation and protection. Furthermore, the smooth sidewall of the second aluminum foil tape 6 facilitates the peeling of the foam layer 5 from the pipeline, making subsequent inspection and maintenance more convenient. The foam layer 5 is made of polyurethane.

[0024] The outer side of the retaining component 4 is covered with a rock wool layer 3, which serves as a fireproof layer and also provides some insulation. A first aluminum foil tape 2 is wrapped around the outer side of the rock wool layer 3. The first aluminum foil tape 2 covers and fixes the rock wool layer 3 to prevent the rock wool from being exposed. Furthermore, when the rock wool layer 3 is wrapped around the retaining component 4, the rock wool can be tied with steel wire.

[0025] The clamping component 4 has several through holes on one side and a second threaded hole on the other side. When two clamping components 4 are spliced ​​together, the through holes on one side of the clamping component 4 fit into the second threaded hole of the other clamping component 4. The two clamping components 4 are structurally identical and can fit into tubular parts. A first bolt 7 is installed through the through holes, and the first bolt 7 fits into the second threaded hole. The end of the first bolt 7 abuts against the second aluminum foil tape 6. The two clamping components 4 are fixedly connected together by the first bolt 7. At the same time, the end of the first bolt 7 abuts against the second aluminum foil tape 6, which can ensure that the gap between the clamping component 4 and the pipe meets the foaming requirements.

[0026] The clamping member 4 has several first threaded holes 9 in its middle. Some of the first threaded holes 9 can be used as injection holes for foaming material, that is, after the clamping member 4 is installed and fixed, foaming material can be injected into the injection holes.

[0027] A second bolt 8 is threaded into the first threaded hole 9, and the end of the second bolt 8 abuts against the second aluminum foil tape 6. The use of the second bolt 8, in conjunction with the first bolt 7, ensures that the pipe is securely positioned between the two assembled clamping parts 4. Since foaming material needs to be injected into the first threaded hole 9, the number and position of the second bolts 8 can be determined according to actual needs.

[0028] Furthermore, since the ends of the first bolt 7 and the second bolt 8 are in direct contact with the second aluminum foil tape 6, if the protective device is subjected to external force, its ends are likely to damage the side wall of the pipe. Therefore, rubber ends are added to the ends of the first bolt 7 and the second bolt 8, or gaskets are installed between the first bolt 7, the second bolt 8 and the pipe.

[0029] The end of the clamping component 4 is provided with two plugs 1, and the two plugs 1 are clamped together on the pipe. The plugs 1 are provided to seal the end of the clamping component 4 to prevent the foaming material from leaking out during the foaming process.

[0030] The end of the plug 1 is provided with a side lug 10, and a third bolt 12 is inserted through the side lug 10. A nut 11 is threaded onto the third bolt 12. The two plugs 1 form a clamp. When the two plugs 1 are clamped together, the side lugs 10 at the same end are attached. Then the third bolt 12 and nut 11 are used to fix the plugs 1 together.

[0031] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features.
