Q. Does Seal Tite restrict the flow through tubing or lead lines?
A. No, it doesn't. In field tests that we have run with oil companies, the flow through our lined tubing and lead lines has been equal to or a little better than through bare pipe.
Q. Why is this?
A. P.V.C. is 50% smoother than steel. This allows more to flow by eliminating friction loss; our V-Cup seal also eliminates turbulence in the collar area.
Q. Does your seal make a restriction?
A. No. Our engineer, and also oil company engineers, tell us that the seal is not long enough to make a restriction. There is a suction created by the venturi-effect of the seal.
Q. What do you back your P.V.C./C.P.V.C. lining with?
A. Pure Portland cement with some chemical additives. This is approximately 1/16" thick.
Q. Can you line used tubing and line pipe?
A. Yes, if it will test and drift to A. P. I. specifications.
Q. What special tools are needed to run Seal Tite P.V.C./C.P.V.C. lined pipe?
A. None. It is designed so that any pulling unit crew or roustabout crew can run it with the tools they would use on a normal tubing job or lead line job.
Q. Can the seals be reused if they are pulled?
A. Yes. However, we do recommend that you replace the O-rings before reinstalling the seals. Replace any seals if cracked or broken when pulling pipe.
Q. Should the packer be lined?
A. Yes. We recommend it because this will let you have a seal at the top of the packer and eliminate a weak link in the string.
Q. What pressures should be used when making up the pipe?
A. The same as you would on a regular tubing or lead-line job and follow the seal installation directions, running the tongs on a medium speed.
Q. Do the seals have to be fitted or go to a special point?
A. No. Once the pin end passes the V-cup you have a seal. Makeup should be no more than one thread showing or just covering the last thread.
Q. Will anything eat up the PVC lining?
A. There are a few chemicals that will; consult the B. F. Goodrich chemical resistance charts which have been included for reference or call SEAL TITE @1-800-835-0133 toll free.
Q. Can we acidize through Seal Tite?
A. Yes. The hydrochloric acids used for this have no effect on the lining or the seal. If using hydroflouric acid, be sure to wash the acid to the formation not allowing it to stand in the static fluid column.
Q. Will tracer tools go through Seal Tite lined pipe?
A. Yes. Most tracer tools are 1 1/4", if you anticipate using larger ones, you might consider using 2 7/8" pipe. Your service companies have tools available for all sizes of our lined tubing.
Q. Can Seal Tite lined pipe be used for producing wells?
A. Yes, but only certain types. It is being used on submersible pumps such as the REDA pump and these wells are working fine. (We DO NOT recommend Seal Tite on rod pumps though there are a few producers that are using it this way.
Q. On lead lines can Seal Tite lined pipe be laid over hills and around corners?
A. Yes, but we don't recommend sharp turns or bends. Common sense and reasonable care should be used when curving lined pipe of any kind.
Q. Where is Seal Tite PVC lined tubing available?
A. Through Seal Tite Distributors, nationwide.
