1. Introduction
Thank you for your purchase of a
Hot Coils
®
Heater. We know you will find the
Hot Coils
®
Heater a valuable addition to your tool kit and
you will benefit from the efficiency, safety and
enviromental advantages that are to be found
over traditional pipe pre-heating methods.
The coil heater is designed to preheat new
piping to specified temperature prior to the
welding sequence (this is usuallyspecified by the
owner/welding procedure/ or the boilers branch,
or any other authority that has jurisdiction).
Also all insitu piping in a H2S service requires a
hydrocarbon bake out prior to cutting or welding
(specified by authority in place). The heater coil
in this case expels the H2S molecules at 550º
F (286ºC) so that cutting and or welding can
commence without fractures to the parent metal.
Hot Coils
®
offer SAFTY ADVANTAGES over
traditional pre-heat techniques.
Hot Coils
®
can be installed quickly and easily.
The coil provides even heat throughout the weld
joint and provides better weld platform as heat is
localized.
Hot Coils
®
offers different models and may not
be exactly as shown in Figures 1 and 2 below.
