Riser welding - conrol heat zone

Riser welding - conrol heat zone

Riser welding - conrol heat zone

(OP)
Does anybody have practical knowledge of a system or product to control the heat generated from a weld. The process being used is Flux Cored MIG, we intend to complete a 7 1/2" horizontal riser butt as topside completion to a flexible riser on a offshore Oil Platform. I would be interested in a compound that suppresses the travel of heat to an adjacent Umbilical Riser.
My thought?

Compound "Cool Pack"
Water powered "Cooling Sleeve"

Has anybody experiance of these are alternatives

RE: Riser welding - conrol heat zone

Hi apple01,
Your best solution would be "silica heat dissipating paste"
and is usually available from repair and maintainance welding alloy companies.It sticks to anything,very effective
as a heat stop,completely re usable and washes off with water easily.I saw it demonstrated once by a rep who covered
his hand with approx 20mm,and proceeded by holding an
oxy-acetylyne welding torch onto his hand for what seemed like a very long time!Bearing in mind that oxy-acetylene
can reach temperatures in the range of 3200 celsius!
Hope you find some quite easy,best of luck,

RE: Riser welding - conrol heat zone

I used some of this stuff about 20 years ago called 'Heat Ban'.  It was very good.  If anyone knows where you can buy this stuff I would like to know as I too have an application for it.
