The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0029] "Top surface", "bottom", "bottom surface" are referenced based on the normal use state of the seamless steel pipe assembly, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to the present utility model.

[0030] As Figure 1-4 shown, a super-clean seamless stainless steel pipe assembly includes a pipe body 1; end covers 8, one of which is respectively provided at both ends of the pipe body 1, and the end cover 8 is hermetically connected to the pipe body 1 through a sealing ring 5; a sealing sleeve bag 2, the bag mouth of the sealing sleeve bag 2 has a sealing part 201, and the pipe body 1 and the end cover 8 are both arranged inside the sealing sleeve bag 2; a buffer assembly 3, there are multiple buffer assemblies 3, the buffer assembly 3 is annular and sleeved on the pipe body 1 and the end cover 8 respectively, and the sealing sleeve bag 2 is located inside the buffer assembly 3.

[0031] The above-mentioned ultra-clean stainless steel pipe assembly is used to seal the pipe body 1 of the stainless steel pipe, ensuring the sealing effect of the pipe body 1 during transportation, reducing the probability of the pipe body 1 being corroded or contaminated, and thus ensuring the performance of the stainless steel pipe. In this stainless steel pipe assembly, the end caps 8 wrap around both ends of the pipe body 1, and the sealing between the end caps 8 and the pipe body 1 is achieved through the sealing rings 5, thereby realizing the sealing of the ends of the pipe body 1 and preventing dust, impurities or moisture from entering the interior of the pipe body 1, achieving the effect of protecting the inner wall of the pipe body 1. The sealing sleeve bag 2 seals both the end caps 8 and the pipe body 1 inside it, thereby realizing the overall sealing protection of the pipe body 1 and reducing the probability of the pipe body 1 being corroded or contaminated. The annular buffer assembly 1 can buffer the mutual collision between the pipe bodies 1 during transportation, reducing the probability of the pipe body 1 being damaged, and at the same time reducing the probability of the sealing sleeve bag 2 being damaged, ensuring the sealing effect of the pipe body 1. Through the buffer assembly 3, the sealing sleeve bag 2 and the end caps 8 can also be strengthened, improving the firmness of the connection between the sealing sleeve bag 2 and the end caps 8 and the pipe body 1, further ensuring the sealing effect of the pipe body 1, thereby reducing the probability of the pipe body 1 being corroded or contaminated during transportation and ensuring the performance and yield rate of the pipe body 1.

[0032] A further improvement is that, as Figure 3 and 6 shown, the sealing ring 5 includes an inner ring 502 circumferentially arranged on the inner peripheral surface of the end cap 8 and an outer ring 501 circumferentially arranged on the outer peripheral surface of the end cap 8. The sealing ring 5 can be made of silicone material. Silicone has good sealing performance and elasticity, making the sealing ring 5 have excellent sealing performance. The inner ring 502 is located between the outer peripheral surface of the pipe body 1 and the inner peripheral surface of the end cap 8, playing a sealing role between the pipe body 1 and the end cap 8 and improving the sealing effect of the end cap 8 on the end of the pipe body 1. Since the ultra-clean seamless stainless steel pipe has extremely high requirements for the purity and cleanliness of the medium inside the pipe body 1 during use, the protection of the inner wall cleanliness of the pipe body 1 is particularly important. Through the setting of the end cap 8, the effect of ensuring the cleanliness of the inner wall of the pipe body 1 can be achieved. The outer ring 501 is located between the sealing sleeve bag 2 and the end cap 8. The outer ring 501 made of silicone material is relatively soft, which can reduce the probability of the end cap 8 scratching the sealing sleeve bag 2, and at the same time can increase the friction between the sealing sleeve bag 2 and the pipe body 1, preventing the pipe body 1 from sliding inside the sealing sleeve bag 2, thereby reducing the wear on the outer surface of the pipe body 1.

[0033] A further improvement is that, as Figure 5As shown, the side wall of the end cover 8 is provided with a plurality of notches 801 along its own axial direction, and each notch 801 is evenly spaced around the axis of the end cover 8. Each notch 801 divides the side wall of the end cover 8 to form a plurality of clamping claws 802. The notch 801 is connected to the outside at one end adjacent to the opening of the end cover 8, and at least one of the inner ring 502 and the outer ring 501 covers the notch 801. The notch 801 is provided so that a gap is reserved between each clamping claw 802, so that the clamping claw 802 can be turned toward or away from the axis of the end cover 8. When the clamping claw 802 is turned, the operation of clamping or loosening the pipe body 1 can be completed, so that the end cover 8 can be applied to pipe bodies 1 of different diameters, thereby improving the practicality of the stainless steel pipe assembly.

[0034] A further improvement is, Figure 6 As shown, the sealing ring 5 also includes an elastic connecting portion 503, and the inner ring 502 and the outer ring 501 are fixedly connected through the connecting portion 503. The number of the connecting portions 503 is equal to the number of the notches 801 and corresponds one to one, and the connecting portion 503 is plugged into the notches 801. The connecting portion 503 is also made of silicone and is an integrally formed structure with the inner ring 502 and the outer ring 501. The connecting portion 503 is a strip structure so that the notches 801 can be filled. Through the setting of the connecting portion 503, firstly, the firmness of the connection between the inner ring 502 and the outer ring 501 can be improved, and the strength of the sealing ring 5 can be improved. Secondly, after the connecting portion 503 is plugged into the notch 801, the firmness of the installation of the sealing ring 5 can be improved, and the sealing performance between the end cover 8 and the tube body 1 can be ensured.

[0035] A further improvement is, Figure 3 and 4 As shown, an isolation net 6 is provided inside the end cap 8, and the isolation net 6 abuts against the end face of the inner ring 502 away from the opening of the end cap 8. The isolation net 6, the bottom wall of the end cap 8 and the side wall of the end cap 8 enclose a space for accommodating the drying element 7. The isolation net 6 is inserted into the inside of the end cap 8, and under the limiting effect of the inner ring 502, the probability of the isolation net 6 falling from the inside of the end cap 8 can be reduced, so that the drying element 7 is limited to the bottom of the end cap 8 through the isolation net 6; the drying element 7 is a bagged desiccant, and the setting of the drying element 7 can reduce the humidity inside the tube body 1, thereby reducing the corrosion of the inner wall of the tube body 1 and improving the quality of the stainless steel tube.

[0036] A further improvement is, Figure 7As shown, the buffer assembly 3 includes an elastic anti-slip sleeve 301 sleeved on the outer periphery of the sealed bag 2. A buffer ring 302 is circumferentially arranged on the outer periphery of the anti-slip sleeve 301; a circumferential annular groove 303 is formed on the outer periphery of the buffer ring 302, and a tie strap 4 is circumferentially arranged inside the annular groove 303. The anti-slip sleeve 301 is made of rubber material and is sleeved on the outer peripheries of the end cap 8 and the pipe body 1, so as to enhance the firmness of the connection among the end cap 8, the sealed bag 2 and the pipe body 1 through the anti-slip sleeve 301, and prevent the end cap 8 from falling off during transportation; the arrangement of the annular groove 303 is used to enhance the stability of the connection between the tie strap 4 and the buffer assembly 3, so as to tie the buffer assembly 3 through the tie strap 4, and further enhance the firmness of the installation of the buffer assembly 3; the buffer ring 302 is made of polyurethane foam plastic and can play a good buffering role. Under the buffering effect of the buffer ring 302, the probability of damage to the pipe body 1 caused by collision can be reduced, and at the same time, the probability of damage to the sealed bag 2 can also be reduced, so as to enhance the protection effect on the pipe body 1 and ensure the performance and quality of the pipe body 1.

[0037] A further improvement is that, as Figure 1 and 2 shown, the sealing part 201 is a self-sealing strip. The self-sealing strip can complete the sealing immediately and quickly without additional tools or equipment, greatly saving time and operation complexity, and can also be reused, greatly improving the convenience of disassembly and assembly of the sealed bag 2.
