We need to connect some cathodic protection
cables to a pipe line (gas and oil in operation)
using Exothermic Weld (Cadweld), and we need to
find specifications, rules where say about of the
Criteria’s which must be had in account to carry
out this activity: maximum operation pressure,
minimum wall thickness, temperatures, etc.
I appreciate your cooperation.

Here is another supplier of exothermic welding products that you might be able to get your required information.

Anecdotal:
The largest pucker factor I've ever seen was when the plant Safety Supervisor walked up on a crew as they lit a charge on the side of a storage tank that contained over a 100,000 lbs. of Cyclohexane. They had been shown the wrong tank by operations. The weld was successful but the copper lead lay exposed for several years until the tank was taken out of service.
The Supervisor was give a exothermic weld connection at his retirement party.
