Question on Sucker Rod Threads

LonM · Sep 24, 2013

I am building some cattle pens with 3/4" and 7/8" used sucker rods. Some of the couplers are a little rough and I want to chase the threads to make it go together faster. What sort of thread type do these have? One neighbor told me pipe thread but that is too fine. Any help would be appreciated!
Thanks,
LonM

McMaster car show 3/4" with 10 and 16 TPI coupling nuts.
7/8"only shows 9TPI.
Comp[ared to what I am used to you have big sucker rods.

Thank You for locating that information. I might have some trouble finding those types of taps....

Yes it is way courser than pipe thread.
3/4 pipe would have 14 threads and 3/4 sucker rod would have 10 threads per inch.

Just curious.......
Was this used pipe checked with a Geiger counter before you drug it home.

if you have a oil field supply store around you try to rent a rod chaser from them I think you might find one that will do both 3/4 and 7/8 I know I have seen a 5/8 and 3/4 tool before you might have to get one for each they will chase both the rods and boxes
Hope this helps

Thanks for your help. I got the rod from a steel warehouse in eastern SD that handles a lot of used oilfield pipe and so forth. Most of their customers use it to build cattle corrals and feedlots. I do not know if it was checked for radiation or not, and it never crossed my mind. I do not know much about the drilling industry either. Does much of this equipment come into contact with radioactive soil?

Thank You for that idea of renting one from a drilling supplier- I'll check into it more if I can't clean them up enough with oil and a wire brush.

Everything the oil drilling companies use comes in contact with Radium; a naturally occurring radioactive material. It is more of a problem of the south but it might be worth checking.
Just take a piece of the pipe to a scrap yard. They can check it to see how hot (if at all) it is.

When I built my catch pen/corral/chute, I used 2 3/8 new pipe for the top rails and sucker for the rest. The guy that did the welding for me brought along some little steel u shaped things made out of about 6 ga. wire that he put over the rod and welded to the vertical posts. Made a lot of sense since the rod was very rusty and the joints of rod to post were less than stellar. Been 8 years and all still intact.

Might want to add them to your project.

The rod box tap we used was a cross 5/8 x 3/4 male and female...If you come up on rods with 2 boxes just lay the box on a sledge hammer head and warm it up good, most of time it will loosen right up..when pulling rods out of well we would have to change boxes because of wear I would use 2 hammers hitting box at same time...

That is a pretty interesting article. I was not aware that it could be a problem, but it makes sense with all the pipe and rod in different types of soils and rock. Its certainly something nobody selling used pipe would tell a customer...
Thanks again,
LonM

We had considered using oil field pipe for posts but opted for railroad ties. Then we bought some clips that hold the rod to the tie with two lag screws. It goes together pretty well. But I have seen corrals and such made entirely of steel pipe and rod like you mention, and I think that is the closest thing there is to a permanent fence!

You do what you can. I started 35 years ago with wood. As time passed the benefits of steel became very obvious. As I got the kids grown and all I had more money to do things the way I wanted to and all my fencing has been with steel.

Line fence is pipe corners and every 100' a weight support with T posts and Gaucho 15 1/2 gauge high tensile barbed wire from Arkansas. The weight support is a pipe sitting in a 12" dia x 3' deep concreted hole to hold up the weight of the wire. Black clay here and in the summer it cracks open and would otherwise swallow the T posts set at about 10' apart. Have not been sorry.
