Problems solved by technology

At present, ceramic heating ropes are generally used to heat-treat the fillet welds. The ceramic heating ropes need to be wound around the fillet welds of the BOSS head or small branch pipes to cover the weld area. Due to the small diameter and short size of the general small branch pipes or BOSS heads, And the welding seam has a slope, the heating rope is inconvenient to wind and fix
It is easy to cause the heating rope to break due to the tight winding of the heating rope on site, and the partial temperature caused by the uneven winding of the heating rope

Abstract

The invention discloses an armored heating sheet for heat treatment of a fillet weld of a small connecting pipe. The heating sheet comprises ceramic chips, a heating wire and heating connectors; the ceramic chips are connected in series through the heating wire; and the heating connectors are installed at the two ends of the heating wire and used for being connected with heat treatment equipment. The armored heating sheet for the heat treatment of the fillet weld of the small connecting pipe provided by the invention is convenient in structure, simple to use, easy to mount, reusable, stable in heat treatment effect and uniform in temperature distribution.

Description

technical field [0001] The invention belongs to the field of heat treatment ceramic resistance heating sheets, in particular to an armored heating sheet for heat treatment of small pipe fillet welds for local heat treatment of BOSS heads and small branch pipe fillet welds at welding construction sites. Background technique [0002] There are a lot of BOSS head welding and welding of small branch pipes at the welding construction site, and local heat treatment is required for some low alloy steel fillet welds. At present, ceramic heating ropes are generally used to heat-treat the fillet welds. The ceramic heating ropes need to be wound around the fillet welds of the BOSS head or small branch pipes to cover the weld area. Due to the small diameter and short size of the general small branch pipes or BOSS heads, And the welding seam has a slope, and the heating rope is inconvenient to wind and fix. It is easy to cause the heating rope to break due to the tight winding of the he...
