Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 6, the present invention provides a technical solution:

the high-pressure-resistant metal corrugated pipe body comprises a heat-insulating layer 1, and a vibration-proof pad 2 is fixedly mounted on the inner wall of the heat-insulating layer 1.

As an embodiment of the present invention, as shown in fig. 1, fig. 3, fig. 4 and fig. 6, the heat insulating layer 1 includes an elastic shell 11, and the elastic shell 11 is a metal steel coil;

clamping tables 12 are fixedly arranged at two ends of the elastic shell 11;

the inner wall of the clamping table 12 is provided with a threaded hole 13, and the surface of the threaded hole 13 is connected with a thread on the surface of a locking bolt 14;

the inner wall of the threaded hole 13 is in threaded connection with a locking bolt 14;

when the device works, the surface of the elastic shell 11 is fixedly provided with the heat-insulating layer 1, and the heat-insulating layer 1 has a good heat-insulating effect, so that a flowing high-temperature medium is prevented from scalding workers, the safety of the device is improved, the thermal stress inside and outside the metal corrugated pipe is reduced, and the risk of cracks on the metal surface is reduced;

during operation, the staff cup joints the device in the outside of corrugated metal pipe, passes the clamp platform 12 with locking bolt 14 and twists screw hole 13 inside, and the staff screws up locking bolt 14 with the spanner afterburning afterwards, and locking bolt 14 pulling clamp platform 12 draws close each other, and clamp platform 12 drives elastic housing 11 incurving to reach elastic housing 11 and give an inward compressive force of corrugated metal pipe, improve corrugated metal pipe's rigidity.

As an embodiment of the present invention, as shown in fig. 2, 5 and 6, the crash pad 2 includes an insulating layer 21, the insulating layer 21 is made of a high temperature resistant material, and a corrugated boss 22 is fixedly connected to an inner wall of the insulating layer 21;
