Fire safe test-API 607
Himan Nikdin
Dear Experts
I have a problem with my vendor regarding interpretation of fire safe test of ball valves, according to clause 4.5.2 of API std 607:
”When a purchase order stipulates fire-tested valves, valves qualified by fire testing as specified in the third or fourth edition of this standard (API Standard 607) may be supplied for a period of 3 years after the date of this standard. After that 3-year period, all certified valves must meet all the requirements of the fourth edition of this standard",
My interpretation of this clause is fire safe test will be expired after 3- years and manufacture shall repeat the test, but the manufacturer this agree with me and tells me that the certificate will never expired.
Would you please share your technical information with me.
Regards,
Himan Nikdin

Dear Mr. Manpreet Singh Many thanks for your response… Actually, I am working as a consultant engineer in crude oil tank construction project in the south of Iraq. They ask me to design ICCP system for tanks and underground pipe. Up to my information connecting of silicon iron electrodes to the tank body was known. The problem is how to connect electrode cable to the underground pipe, I think they used a special procedure to do that…..So, would you please help me with an information about the standard method or any other method…. Accept my profound regards… |

Dear Friends,
Connection with cable to pipe / tank is by means of thermit welding with thermit weld cartridges, and further to that epoxy will be used for sealing
Sequence of photos are attached for your reference.
Pic 1.
Removal of insulation on the pipe and for the cable.
Placing the cable on to the position and keeping thermit welding cartridge on the cable
Filling of gun powder in the cartridge
Pic 2
Firing of the gunpowder.
Cleaning of the weld debris.
Pic3
Placing of canopy on the cable and opened insulation spot.(100 mm dia PVC pipe piece)
Mixing of epoxy part A and part B as per manufacturer stds
Pouring the liquid epoxy in to the canopy’s.
Within 4-6 Hrs liquid epoxy will become hard and cathodic insulated.
Thanks and Regards................?

From the below post, I reckon that the information you need is how to connect electrode cable to the underground pipe:-
*All cables should be carefully inspected to detect defects in insulation and the cable for the rectifier negative terminal should be connected to the Pipe (structure to be protected), cable connections to the rectified must be mechanically scure and electrically conductive.
*All buried or submerged lead wire attachments should be coated with an electrically insulating material, compatible with the external pipe coating and wire insulation.
Please notify if further information is needed.

Manpreet Singh
