It improves the compressive strength of the seamless tube, thereby ensuring the service life of the seamless tube.
[0016] 3. This utility model achieves the effect of supporting the inner wall of the seamless steel pipe by setting up an inner lining column, a support column, an alloy column, a support rod, and a support plate. A support plate is set at the end of the support rod, and a support groove is provided on the inner surface of the seamless pipe at the position of the support plate. The support plate is fitted into the support groove. A support column is set on the outer surface of the inner lining column, and a support rod is set on the outer surface of the support column.

The ceramic heat-resistant layer 11 is a special coating, typically composed of ceramic particles or powder mixed with a binder, used to improve the high-temperature resistance, wear resistance, and corrosion resistance of the substrate. This can effectively improve the high-temperature resistance and durability of the equipment, extend its lifespan, and reduce maintenance. Cost is one of the important surface protection technologies in the industrial field. The inner surface of the outer tube 1 is provided with a slot 10 at the position of the clamping platform 12.

The energy-absorbing liner 17 and the support tube 15 support the outer tube 1. When the present invention is subjected to force, the energy-absorbing liner 17 and the support tube 15 absorb the force, thereby protecting the present invention. Thus, the working process of the device is completed.

[0029] In this embodiment, during use, the inner lining column 9 supports the support column 5, and the support column 5, support rod 4 and support plate 19 support the inner wall of the seamless tube 3, thereby improving the support strength of the seamless tube 3. The alloy column 8 supports the inner lining column 9, thereby improving the strength of the inner lining column 9, and thus improving the support strength of the seamless tube 3.
