Abstract
Description
Technical Field
[0001] The utility model relates to a novel stainless steel seamless coil pipe. Background Art
[0002] In the prior art, the stainless steel seamless coil is a smooth coil. The coil of this structure has the following shortcomings: due to the high strength and toughness of the coil, when cutting the coil, its length (cutting position) can only be roughly judged according to the number of turns of the coil, resulting in low accuracy of the length of the coil after cutting; the cut coil also needs to be processed with a joint at its end, or it can be connected to the connecting end of the device after using a connector, which is relatively inconvenient to use, and the use of the connector will add two more seams, resulting in an increased possibility of leakage; similarly, when two or more discarded coils removed from the equipment need to be connected for reuse, the connection of the two discarded coils is also quite inconvenient. Utility Model Content
[0003] The utility model aims to overcome the deficiencies of the prior art and provide a novel stainless steel seamless coil, which has the advantages of being easy to measure length, easy to connect corresponding equipment, and easy to butt two coils.
[0004] The technical solution of the utility model is: a novel stainless steel seamless coil, comprising a pipe body, on which a plurality of reduced diameter sections are arranged at equal distances, the outer diameter of the reduced diameter sections corresponds to the inner diameter of the pipe body, and a sheath is also arranged on the reduced diameter section, the outer diameter of the sheath is consistent with the outer diameter of the pipe body;
[0005] After the pipe body is cut into reduced diameter sections, the reduced diameter sections form joints, which are used for butting the connection ends of application equipment and also for butting two cut pipe bodies.
[0006] Furthermore, the two ends of the tube body respectively have a head end and a tail end.
[0007] Furthermore, a limiting ring is provided at the connection between the tube body and the reduced diameter section, and the limiting ring is used to limit the position of the sheath.
[0008] Furthermore, the end angle of the connection between the tube body and the reduced diameter section is an arc-shaped transition angle.
[0009] Furthermore, a sealing ring is provided at the joint of the two cut tubes, and a cut sheath is sleeved on the limiting ring of one of the two cut tubes that retains the reduced diameter section, and the sheath is used to abut the sealing ring.
[0010] Optionally, the outer periphery of the tube body is also covered with a metal mesh sleeve.
[0011] Optionally, the outer periphery of the tube body is also covered with a rubber sleeve.
[0012] The beneficial effects of the utility model are as follows: a one-meter spacing is maintained between the reduced diameter sections on the unfolded coil, which provides a reference for cutting the pipe body and overcomes the disadvantage of inconvenient length measurement when cutting the coil; after the coil is cut according to the reduced diameter section, the reduced diameter section forms a joint, which can be directly used for connecting the connecting end of the application equipment, without the need to process the joint or add connecting parts later, thereby reducing the seams and further reducing the possibility of leakage; when the two sections of the cut coil need to be connected, only the connection between the middle pipe body and the reduced diameter section of one coil needs to be cut off, and the reduced diameter section of the other coil can be inserted into the cut portion of the other coil and then welded, so that the connection at the connection is reliable, which is conducive to the reuse of two or more discarded coils.

[0020] After the pipe body 1 is cut according to the reduced diameter section 2, the reduced diameter section 2 forms a joint 4, and the joint 4 is used for connecting the connection end of the application equipment and also for connecting two cut pipe bodies 1.
[0021] In the above structure, the reduced diameter sections 2 on the unfolded coil are kept at a distance of one meter, which provides a reference for cutting the pipe body 1 and overcomes the disadvantage of inconvenient length measurement when cutting the coil; after the coil is cut according to the reduced diameter section 2, the reduced diameter section 2 forms a joint 4, which can be directly used for connecting the connecting end of the application equipment, without the need to process the joint 4 or add connecting parts later, thereby reducing the seams and the possibility of leakage; when the two sections of the cut coil need to be connected, only the connection between the middle pipe body 1 and the reduced diameter section 2 needs to be cut off, and the reduced diameter section 2 of the other coil can be inserted into the cut part of the other coil and then welded, so that the connection at the connection is reliable, which is conducive to the reuse of two or more discarded coils.
