Tie-ins 24 miles of 24 inch pipe FBE the job consisted of a few welds a day. When we didn’t have welds we would fall back and jeep the pipe we had previously been working on. We would simply heat the welds depending on the ambient temperature that had been taken from the pipe. We then proceeded to heat the weld drive all the moisture out and hit the desired temperature within specifications, then we would sandblast. I would check anchor profile with testex tape and look for any dark spots and make sure the feathering was 3 inches to the sides looking for rust spots. If it all checked out according to standards near white blast we would then proceed with checking batch numbers from the coating container and verifying the expiration date.

As long as everything checked out we would mix the 2 part epoxy I would keep up with the start time. While applying the coating I would verify mils with a wet film thickness gauge make sure we didn’t have any runs, sags and allow the coating to cure. Afterwards I would get dry film thickness readings and find the average to then set and calibrate the jeep. Once that had been done we would jeep and patch any holidays. I would write down how many holidays we found and get them patched and re-jeeped.

Mainline sandblasting and coating 20 inch FBE 11 miles. I was responsible for keeping up with paperwork and working amongst other labors. I kept up with weld numbers, anchor profiles, batch numbers, expiration dates on coating containers, start and stop times of coating application on welds, number of holidays per weld. Calibration of jeep.

I would start by taking ambient temperature and depending on that we would start by heating the welds to remove the moisture then would proceed to sandblast. I would make sure the feathering was 3 inches to each side of the weld and was up to standards near white blast. I would then get testex tape and apply on the weld at 12,3,6,9 and check every 5 welds and I would proceed to get the coating container get the batch number and see the 2 part epoxy get mixed and and time of application. I would then use a wet film thickness gauge and check coating thickness and allow the coating to cure and the crew towards the end of the day would fall back and jeep doing repairs as necessary.

Tie-ins 12 inch FBE pipe. I helped coating inspector gather information such as weld numbers, batch number and expiration dates of coating containers. I would get anchor profiles with surface profile gauge and verified to be in order with specs. Heat the weld to temperature that was specified. Continue with mixing 2 part coating writing down temperature of coating and what time the application of coating began, often checking wet film thickness with wet thickness gauge and allow the coating to cure to proceed with dry film thickness using a digital dry film thickness gauge average out the mils of the coating and setting jeep to correct voltage jeep the welds and repair any holidays found and re-jeep to verify no other jeeps were missed.

Station job sand blasted and coated valves and jeeped any weld and any exposed pipe.

This was a short compressor station job. I helped the lead inspector with any weld numbers needed and ambient temperatures. I would then heat the welds to desired temperature to run the moisture of the pipe and proceed to sandblast. Then I got my anchor profiles with testex tape and as long as specs from client were met, I would proceed and get batch number from coating container, along with expiration date and would mix the 2 part epoxy coating which was Denso 7200. I would keep up with the time of application and verify thickness with wet film thickness gauge. Allow time for coating to cure or would sometimes get indirect heat to help cure to then get dry film thickness at 12,3, 6 and 9 around the weld and average out the mils and proceed to calibrate the jeep and jeep the weld if any holidays were found then it would be scuffed with sandpaper and cleaned free of any debris heated and coated with patch kits.

• Prepared surfaces for sandblasting by removing rust, dirt, paint, and other debris.
• Set up and operated sandblasting equipment according to safety protocols.
• Cleaned and maintained all sandblasting equipment after each job was completed.
• Inspected parts before and after sandblasting process to ensure quality control standards were met.
• Followed established environmental regulations when disposing of waste generated from projects.
• Used hand tools such as chisels, hammers, scrapers, wire brushes., for more detailed cleaning tasks.

Mainline 12 inch FBE pipe. I kept up with weld numbers and would get ambient temperature. I would then run a blotter test 2 times a day. Then heat pipe in order to get moisture out and heating the pipe to cure coating when applied. sandblasted to required specifications.

I would then get batch number, dates of the coating container then I would proceed to mix 2 part epoxy coating. I would write down start time and check thickness, with wet and dry film thickness gauge. Towards the end of the day we would fall back and jeep the pipe, do any patch work necessary and then would re-jeep the pipe.

Tie-ins 42 inch pipe FBE. First thing was to get ambient temperature, weld numbers, heat pipe, get moisture out. Sandblast continue to get anchor profile. Making sure weld were up to standards. I then had 2 part epoxy, proceeded to verify number from coating buckets to make sure we didn’t have expired product. I would write down batch numbers. I would Oversee mixing of both parts before mixing together, while getting temperature of coating and the time of mixing and application. I would then use wet film thickness gauge to verify coating thickness and would allow pipe to be heated with indirect heat and cure the coating. I would proceed to get dry film thickness for calibration of jeep. Then jeep the weld and if holidays were found we would then scuff with sandpaper, heat and coat and Re-jeep.

• Mainline sand blasting and coating FBE and 32 inch FBO pipe that was used for bore. I would check the sandblasting rig and proceed to do a blotter test. Depending on ambient temperature, then would heat welds to remove all moisture check the ambient temperature again. Sand blast the weld and would then proceed to get anchor profile standard of near white blast.
• After desired anchor profile and cleanliness the crew and myself would proceed to mix 2 part epoxy 2888. I would write down batch numbers dates and times of application of the coating. While applying coating, I would check thickness with wet film thickness gauges, allow time for the coating to cure and proceed to the next weld. I would keep up with the anchor profile, temperature, what time the coating was mixed and applied. Towards the end of the day the crew would fall back and jeep the work we had finished and do patch work to any holidays found.

Mainline sandblasting and coating 42inch pipe FBE as a mainline crew, I made sure that we had brushes, coating, mixing paddles, patch kits, propane tanks, sand paper, grinders, sand for the sandblasting rig anything that was needed.

Part of my paperwork was writing down weld numbers keeping count of how many welds had been sandblasted and coated. Keeping up with how many coating buckets, brushes, and sand had been used, to be able to place for orders.

My job out in the field was getting weld number ambient temperatures. Sandblasting to required specs from the client. Then I would write down the batch numbers of the coating. I would oversee the mixing of the two parts before adding them together. I would write down the time of the application and would often get thickness with wet film thickness gauge proceed to let the weld cure then getting dry film thickness and go on repeating the same steps throughout the day and once we had achieved the desired amount of welds. The crew would fall back and jeep and do patch work and re-jeep any holidays that had been patched.
