[0001] This utility model relates to the field of stainless steel pipe technology, specifically to a stainless steel pipe with strong heat insulation and pressure resistance. Background Technology

[0002] Stainless steel pipe is a metal pipe material with excellent corrosion resistance. It is made of stainless steel strip or plate through forming, welding, heat treatment and surface treatment. Its core component is iron, with the addition of ≥10.5% chromium, nickel, molybdenum and other alloying elements to form a dense chromium oxide protective film, which effectively resists the corrosion of water, air and chemical media. It is suitable for humid and corrosive environments. According to the structure, it can be divided into seamless pipe integral forming, pressure-bearing pipe and welded pipe with low cost and flexible specifications. According to the application, it covers decorative pipe with bright surface, used for furniture and building decoration; industrial pipe with high pressure resistance, used for petroleum, chemical, food machinery and sanitary pipe with polished inner wall, which meets the hygiene standards of the pharmaceutical and food industries. It has a long service life of up to 50 years or more, low maintenance cost, environmental protection and pollution-free, and is recyclable. It has a wide range of applications, such as building water supply and drainage systems, automobile exhaust systems, medical devices, marine engineering, etc. With the development of technology, new products such as ultra-thin wall pipes and special-shaped pipes are constantly emerging to meet the needs of precision manufacturing and have become an indispensable basic material for modern industry.

[0003] The prior art patent document CN222085372U provides a stainless steel pipe with a double-layer structure consisting of an inner tube and an outer tube, which can improve the overall compressive strength of the stainless steel pipe. The cavity is equipped with a reinforcing plate, which further improves the overall strength of the stainless steel pipe. However, existing stainless steel pipes generally lack effective insulation structures, and the heat of the medium inside the pipe is easily lost, which not only wastes energy and increases the cost of use, but may also affect the normal temperature requirements of the medium. Under complex stress environments or external impacts, stainless steel pipes are prone to deformation or even breakage, leading to medium leakage. Therefore, we need a stainless steel pipe with strong heat insulation and pressure resistance. Utility Model Content

[0004] The purpose of this utility model is to provide a stainless steel pipe with strong heat insulation and pressure resistance, so as to solve the problem mentioned in the background art that existing stainless steel pipes generally do not have strong heat insulation and pressure resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel pipe with strong heat insulation and pressure resistance, comprising a first pipe, a connecting component on one side of the first pipe, a second pipe on one side of the connecting component, a pressure-resistant component inside the first pipe, the pressure-resistant component comprising a fixing block, a rotating shaft rotatably connected to one side of the fixing block, a screw fixedly connected to one end of the rotating shaft, a threaded sleeve threadedly connected to the outer wall of the screw, and a support ring provided at one end of the threaded sleeve.

[0006] Preferably, the connecting assembly includes a first flange, which is fixed to one side of the first pipe. A bolt is provided inside the first flange, and a nut is provided on the outer wall of the bolt. A first sealing gasket is fixedly connected to one side of the first flange. An insulation layer is provided inside the first pipe. A second flange is fixedly connected to one side of the second pipe, and a second sealing gasket is provided on one side of the second flange.

[0007] Preferably, the first flange and the second flange form a detachable structure by bolts, and one end of the bolt passes through the first flange and the second flange to connect with a nut.

[0008] Preferably, the first flange and the second flange form a sealing structure through the first sealing gasket, and one side of the first sealing gasket is fitted to one side of the second sealing gasket.

[0009] Preferably, the fixing block forms a rotating structure with the screw via a rotating shaft, and the rotating shaft is disposed between the fixing block and the screw.

[0010] Preferably, the support ring forms a threaded structure with the screw through a threaded sleeve, and the inner diameter of the threaded sleeve matches the outer diameter of the screw, and the inner wall of the threaded sleeve is fitted to the outer wall of the screw.

[0011] Preferably, there are multiple support rings inside the first pipe, and the multiple support rings are evenly spaced inside the first pipe.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this stainless steel pipe has strong heat insulation and pressure resistance. (1) By rotating the screw, it can rotate flexibly on one side of the shaft and inside the threaded sleeve, thereby driving the threaded sleeve to move, so that the support ring can accurately fit the inner wall of the pipe. This design provides reliable internal support for the pipe, greatly enhancing the stability of the pipe. When the pipe is subjected to external pressure, the support ring can effectively disperse the pressure, prevent the pipe from deforming or being damaged due to excessive pressure, significantly improve the pressure resistance of the pipe. Moreover, the component is easy to operate and can flexibly adjust the support position and force according to the actual situation of the pipe, ensuring that the pipe can operate safely and stably under various complex working conditions and extending the service life of the pipe. (2) By precisely connecting the first pipe and the second pipe, the first flange and the second flange are connected, and the first gasket and the second gasket are tightly sealed, which greatly improves the sealing performance of the pipe connection, effectively prevents media leakage, and ensures the safe and stable operation of the pipeline system. Moreover, the connection method of bolts through the two flanges and then fastening with nuts is not only easy to operate and can quickly complete the pipe connection, but also facilitates subsequent disassembly and maintenance, greatly improving construction efficiency and reducing maintenance costs, and providing a reliable guarantee for the high-quality construction and long-term use of pipeline projects.

[0019] Further such as Figure 2 As shown, there are multiple support rings 405 inside the first pipe 1, and the multiple support rings 405 are evenly spaced inside the first pipe 1. By setting multiple support rings 405, the multiple support rings 405 can fit into the inside of the first pipe 1 for fastening and support.

By connecting the first pipe 1 and the second pipe 3... The connection allows the first pipe 1 to be connected to the second pipe 3, and the first flange 201 to be connected to the second flange 206. At the same time, the first sealing gasket 204 on the first flange 201 and the second sealing gasket 207 on one side of the second flange 206 are fitted and sealed, thereby improving the connection sealing between the first pipe 1 and the second pipe 3. In addition, the bolts 202 pass through the first flange 201 and the second flange 206, and are tightened by the nuts 203, which facilitates the connection between stainless steel pipes.
