Abstract

The natural gas burning bent pipe heater includes semi-circular heater, bent pipe opening-closing structure, jet and adjustable locating unit. The bent pipe opening-closing structure is a hinge mechanism comprising operating handle and hinge; the jet consists of air regulating screw sheet, nozzle and outer jet pipe; and the adjustable locating unit consists of locating clamp board, guide block and fixture. The present invention has small volume, easy moving, fast heating, easy operation and low cost. It may be used in heating to fasten various unions of shape memory alloy, annealing to eliminate stress, etc.

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...
