Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0024] Example 1:

[0025] This embodiment provides an enhanced stainless steel braided corrugated pipe, comprising:

[0026] Pipe body 1, with a straight connector 2 and an elbow 3 connected to both ends of pipe body 1 respectively;

[0027] Adapter 4 is welded between pipe body 1 and straight head 2, and between pipe body 1 and elbow 3;

[0028] Connecting nuts 5 are fixedly fitted on the other end of both the straight head 2 and the elbow 3.

[0029] As can be seen in this embodiment, the two ends of the pipe body 1 are respectively connected to a straight connector 2 and an elbow 3. The pipe body 1 is the main channel for fluid transportation and is made of stainless steel, which has good corrosion resistance and strength. The outer side of the pipe body 1 is provided with a braided coating layer made of stainless steel wire. The coating layer is tightly wrapped around the outside of the pipe body 1 through the braiding process, which can effectively enhance the pressure resistance and tensile strength of the pipe body 1. The two ends of the pipe body 1 can be equipped with straight connectors 2 or elbows 3 according to different needs. There are conversion joints 4 welded between the pipe body 1 and the straight connector 2, and between the pipe body 1 and the elbow 3. The other... One end is fixedly fitted with a connecting nut 5, and the inner wall of the connecting nut 5 is provided with a thread. An adapter 4 is added between the pipe body 1 and the straight head 2 or elbow 3. The adapter 4 isolates the discoloration problem at the welding position. After laser welding, bright annealing is used to ensure that there is no discoloration on the inner surface of the product. The existing products are argon arc welded to the corrugated pipe and the joint, and there are defects such as weld slag, weld spots, yellowing, blackening and bluing on the inner and outer surfaces. Compared with the existing technology, the welding adapter 4 will not have defects such as weld slag, weld spots, yellowing, blackening and bluing. Moreover, the adapter 4 can enhance the pressure resistance of the stainless steel braided corrugated pipe.

[0031] This embodiment provides an enhanced stainless steel braided corrugated pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0032] The adapter 4 is laser welded to the pipe body 1.

[0033] As can be seen from this embodiment, the conversion connector 4 and the pipe body 1 are laser welded. The high energy density of the laser enables rapid welding, and the heat-affected zone is small, which avoids deformation or damage to the welded part, and effectively prevents the generation of weld slag and weld spots.

[0034] Example 3:

[0035] This embodiment provides an enhanced stainless steel braided corrugated pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] The adapter 4 has a protective sleeve 6 welded to its outer side.

[0037] As can be seen from this embodiment, a protective sleeve 6 is welded to the outside of the adapter 4. The protective sleeve 6 is made of metal and protects the adapter 4 from damage caused by collisions during installation and use.

[0038] Example 4:

[0039] This embodiment provides an enhanced stainless steel braided corrugated pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] The sheath 6 has a steel wire 7 inside.

[0041] As can be seen from this embodiment, the sheath 6 is provided with steel wires 7 inside. The steel wires 7 are evenly distributed inside the sheath 6 and are tightly fitted with the sheath 6. The steel wires 7 enhance the strength and deformation resistance of the sheath 6, and further improve the protection effect on the adapter 4.

[0042] Example 5:

[0043] This embodiment provides an enhanced stainless steel braided corrugated pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0044] Both the straight head 2 and the elbow 3 are provided with a limit ring 8 at the end away from the pipe body 1. The two ends of the limit ring 8 are respectively provided with a first sealing ring 9 and a second sealing ring 10. The first sealing ring 9 fits into the limit ring 8 and the connecting nut 5.

[0045] As can be seen in this embodiment, a limiting ring 8 is provided at the end of the straight head 2 and the elbow 3 away from the pipe body 1. A first sealing ring 9 and a second sealing ring 10 are respectively provided at both ends of the limiting ring 8. The first sealing ring 9 fits into the limiting ring 8 and the connecting nut 5. The limiting ring 8 is used to limit the connection position and ensure the accuracy of the connection. The first sealing ring 9 and the second sealing ring 10 provide good sealing performance to prevent fluid leakage.

[0046] Example 6:

[0047] This embodiment provides an enhanced stainless steel braided corrugated pipe, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0048] A connecting ring 11 is fitted on the outer wall of one end of the straight head 2 and the elbow 3 located inside the connecting nut 5. The second sealing ring 10 fits against the connecting ring 11 and the limiting ring 8. Slots 12 are opened at both ends of the side wall of the connecting ring 11. An inclined groove 13 is provided on one side of the slot 12. Protrusions 14 are fixedly connected to both sides of the inner wall of the connecting nut 5.

[0049] As can be seen in this embodiment, the connecting ring 11 is sleeved on the outer wall of one end of the straight head 2 and the elbow 3, and the connecting ring 11 is located inside the connecting nut 5. The two ends of the side wall of the connecting ring 11 are provided with slots 12, and a slanted groove 13 is provided on one side of the slot 12. The inner walls of the connecting nut 5 are fixedly connected with protrusions 14. After the connecting ring 11 is sleeved on one end of the straight head 2 and the elbow 3, it is pressed towards the end of the limiting ring 8, thereby pressing the first sealing ring 9 and the second sealing ring 10 to improve the sealing performance. The protrusions 14 pass through the slots 12 and press and rotate the connecting ring 11. The slanted groove 13 can provide a channel for the protrusions 14 to rotate out of the slots 12, thereby limiting the connecting ring 11 and improving the sealing performance.

[0053] As can be seen from this embodiment, two limiting grooves 15 are symmetrically opened on the surface of the connecting ring 11. After the protrusion 14 is inserted into the limiting groove 15, under the elastic force of the first sealing ring 9 and the second sealing ring 10, the protrusion 14 is locked in the limiting groove 15, thereby locking the connecting ring 16 and preventing it from rotating.
