[0032] The outer tube assembly 100 includes a first abutting strip 120 that fits against the outer wall of the pressure-resistant assembly 200. The top end of the first abutting strip 120 is provided with a first abutting surface 130. The end of the first abutting strip 120 away from the pressure-resistant assembly 200 is connected to the outer tube 110.

[0033] The compression-resistant component 200 includes a first compression-resistant plate 210 that is in contact with the first contact surface 130. Both ends of the first compression-resistant plate 210 are connected to compression-resistant strips 220. A second compression-resistant plate 230 is fitted to the end of the compression-resistant strip 220 away from the first compression-resistant plate 210.

[0034] The above-mentioned structural design facilitates the transmission of pressure from the outer tube 110 to the first abutment strip 120 when the outer tube 110 is subjected to external pressure or impact. The first abutment strip 120 then transmits the force to the first pressure-resistant plate 210. The first pressure-resistant plate 210 is subjected to pressure and generates an inward pulling force, thereby pulling the pressure-resistant strip 220. The pressure-resistant strip 220 transmits the tensile force to the second pressure-resistant plate 230. The pressure is then transmitted to the pressure-bearing component 300, which in turn transmits the pressure to the keel component 400 before finally transmitting it to the inner tube 500.

[0035] When the outer tube 110 is subjected to pressure, the pressure is absorbed and resisted through multiple structures, thereby greatly enhancing the pressure resistance of the stainless steel pipe. At the same time, due to the hollow design of multiple parts inside, combined with the mechanical structure layout, the stainless steel pipe can reduce weight and cost while maintaining excellent pressure resistance.

[0037] The structure design described above, through the compression-resistant assembly 200, when one position of the outer tube assembly 100 is subjected to pressure, the pressure received is transmitted to a larger area through the compression-resistant assembly 200, so that the stress area is increased and the pressure received by a single area is reduced, and because the compression-resistant piece is distributed in an equidistant array along the circumferential direction of the outer tube assembly 100, the compression resistance of the entire circumferential direction of the stainless steel pipe is uniform, and pressure received in any direction can be transmitted to the compression-resistant assembly 200 and the pressure is dispersed through the compression-resistant assembly 200.
