AI Technical Summary

Problems solved by technology

Similar to other known tube heat treatment techniques, the apparatus disclosed by Sherman et al. can only treat a relatively small portion of the tube surface at a time, resulting in a slow and inefficient heat treatment process

Embodiment Construction

[0021] Directional terms such as "near", "far", "longitudinal", and "transverse" in the following description are used for relative reference purposes only, and are not intended to indicate how any object is positioned during use, or how it is mounted on a Any restrictions on how the component is installed or relative to the environment.

[0022] Embodiments described herein relate to methods for heat treating one or more interior surfaces of elongated cavities of a target structure, and in particular of tubular structures or other closed structures having longitudinally extending cavities. heat treatment device. One application where the described embodiments can be used is in the bonding of coatings to the interior surfaces of pipes. The thermal processing apparatus includes a process head having as a heat source an array of high intensity heat lamps, such as plasma arc lamps; the plasma arc lamps are lengthwise (i.e., longitudinally) arranged on the process head to allow t...

Abstract

A heat treatment apparatus for heat treating an inner surface of a longitudinally extending cavity of a target structure, the heat treating apparatus having a machining head comprising a longitudinally extending central support member and a distal end protruding transversely from the central support member. end caps and proximal end caps. Each end cap has a plurality of apertures configured to respectively receive the distal and proximal ends of the elongated plasma arc lamp and position the plasma arc lamp to extend longitudinally along the central support member and around the central The support member extends transversely to direct radiation generally emitted by the plasma arc lamp generally radially outward from the processing head. The process head also includes a coolant path having a heat exchange region in thermal communication with the plasma arc lamp, and coolant supply and coolant return conduits in fluid communication with the heat exchange region.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 61 / 828,102, filed May 28, 2013, the contents of which are hereby incorporated by reference. This application also claims priority to US Patent Application No. 14 / 090,885, filed November 26, 2013, the contents of which are hereby incorporated by reference. technical field [0003] The present disclosure generally relates to apparatus for heat treating the interior surface of an enclosed structural member, such as a pipe. Background technique [0004] Heat treatments are often performed on the interior surfaces of pipes and other closed structural members to improve certain mechanical properties of the structural member, such as increased corrosion resistance and surface strength. For example, a plating or coating can be deposited on the inner surface of the tube and bonded to the tube by applying heat from a high density heat source. Known high-...
