We usually just receive them from customer and perform a fluorescent mpi using a yoke, I think they perform functional tests such as checking latches and load test of lugs. What specs are used? Can eddy current be used as an alternative to MPI? thanks Post Reply      Translate            17:25 Aug-15-2009 Andreas NDT Inspector, Specially in the oilfield Tuboscope Vetco(Deutschland)Gmbh, Germany, Joined Oct 1999 126 Re: drill collar elevator inspection In Reply to anjafo at 23:24 Aug-13-2009 (Opening). The specification is the API Spec 8B.Spec specified MPI . Depends on working time you need to perform a 6 month or yearly inspection.For the 6 month inspection the elevator need not to be disassembled and only the accessible load bearing zone need to be inspected.For the yearly inspection the elevator need to be disassembled and 100% of service need to be inspected. Remark: Before I inspect something ,I should know the specification for the inspection ,otherwise how you know the acceptance criteria etc. Regards Andreas Post Reply      Translate            17:32 Aug-15-2009 anjafo NDT Inspector Norway, Joined Aug 2009 204 Re: drill collar elevator inspection In Reply to Andreas at 17:25 Aug-15-2009 . Thanks. Is the acceptance criteria in the API spec? Thats why Im looking into these things as there is a couple of things we test regular that we dont have the best procedures for. WECO connections is another one? Post Reply      Translate            17:37 Aug-15-2009 shajeer hashim Re: drill collar elevator inspection In Reply to anjafo at 23:24 Aug-13-2009 (Opening). See, the crack might happen at any where during handling, so the client will ask the costumer to do inspection before and during drilling. It’s very difficult to say what spec. using for inspection. Usually costumer asks us to find crack. No, eddy current inspection can be done on painted surface. it need proper caliberation. But in MPI surface must be clean with out any particles. As a matter of fact we won’t get it clean(with out paint). We get the surface with more than 3 or more coats of paint. Both have its own limits. This is my opinion. I don't know about others.

GET THE SPEC AND YOU WILL SEE: Regards Andreas PS: No cracks aloud and dimension on load bearing port.

When we get them they are usually shot blasted so this is good. And we use the "no cracks" or "severe mechnical damage" as the acceptance criteria. Dont find much else anyway.

Thats why the spec secified the inspection intervall as guide , the inspection intervall can be shorten to. Also stated the spec that you need to fellow the recomendation of the manufacturer and he you supply you als with drawings of the critical areas.

What's about the dimension of the so called ears and the allowance of play on the center pin etc. Get the spec read them and work according to them and fellow also the requirements of the manufacturer and of the owner or user when given. Anyway I surprise that elevator are used foe the handling of drill collars.

Drill collars can attach with oilfield equipments. Drilling machine is important working equipment for used heavy pressure drilling tools and machine for work. Post Reply      Translate
