Description

technical field

[0001] The invention belongs to a heater, more precisely the invention relates to a tube heater. Background technique

[0002] In the aerospace, chemical, power, machinery and petroleum industries, in order to quickly heat the shape memory alloy pipe joints, so as to achieve the purpose of fastening the pipe ends and realizing the pipe connection. The method of induction heating is adopted at home and abroad, and its characteristic is that the pipe joint is heated rapidly and the temperature rise of the inner layer of the pipe is low, which should not cause the deterioration of the anti-corrosion layer on the inner wall of the pipe. However, the induction heating equipment is complex, expensive, difficult to maintain, and inconvenient to carry, so it is not suitable for use in projects with mobile construction sites. Contents of the invention

[0003] The purpose of the present invention is to ove...
