Another Gas Spud Job
« on: March 19, 2020, 07:22:24 PM »
We have a large job coming up, where the facility, has since day one have burnt oil, they now want to have the ability to burn either oil or natural gas. The area does not have natural gas, too mountainous, too few people and a poor utility infrastructure. They have decided to set the facility up as a burner of compressed natural gas, trucked to the facility in specially designed tank trailers. The compressed natural gas station, will have 10 tanker bays, with tank trailers in transit on a daily basis.

The original burner was sold as an oil burner with the possibility of future gas hook up. The original seller, sold the burner with the gas ring, but none of the other parts of the necessary for gas operation, so I’ve had to fabricate multiple pieces to get the burner set up for gas operation.

The needed (40) 3/8” stainless steel pipe x 4-1/4” gas spuds with (10) 3/16” gas holes, in a diamond pattern, with a sealed top.

I started with (40) 3/8” x 5” stainless steel nipples, then cut to the correct length, the holes drilled, the end of the nipple tapped for a 1/4” npt stainless steel pipe plug, the cut off flush, then faced in the lathe. The next set is for a smaller burner, so the spud sizing and orifice size and pattern will differ.

seems stupid to convert to gas when none is available. Doesn't their oil last longer than the amount of gas required?


Good work for you, stupid in theory. The seller knew they would never need the rest of the gas options... at least he thought.


Who's paying for the job, the seller, or the company?

Manual, I drew a line on the spud, then using a centering jig with 4 evenly spaced hole marks, drilled the 4 center holes, then rotate the spud 45 degrees, and centered 3 holes on the 4 hole already drilled, the rotated the spud again tp place the second set of holes 45 degrees from the original holes and drilled 3 more holes, giving me the 10 required holes.

Cool.   Job like that is screaming for a rotary with a chuck or indexing head.
