I-API 5CT Blast Joint For Completion Pipe String

I-Blast Joint iyingxenye ebalulekile ekusebenzeni kukawoyela negesi, eklanyelwe ukuhlinzeka ngokuvikelwa entanjeni yeshubhu futhi inciphise umthelela wokuguguleka kwangaphandle oketshezini olugelezayo.Yakhiwe kusetshenziswa insimbi yekhwalithi ephezulu enezinga lokuqina elisukela ku-28 kuya ku-36 HRC ngokusho kwe-NACE MR-0175.
Lokhu kuqinisekisa ukuqina nobuqotho bayo ngaphansi kwezimo ezinzima.

Ngokubeka ngokuhlelekile ilunga lokuqhuma elibhekene nezimbobo zomthombo noma ngaphansi kwe-tubing hanger ngesikhathi sokuphuka kwesihlabathi, kunikeza ungqimba olwengeziwe lokuzivikela entanjeni yeshubhu.Ukwakhiwa kwamashubhu anezindonga ezinzima ze-blast joint kuvikela amandla okuguguleka futhi kuvimbele ukulimala kwezinto zokukhiqiza.

Ukuze kugcinwe ububanzi obugcwele obugcwele ngaphakathi kweshubhu, i-blast joint yakhelwe ukuthi ibe nobubanzi obufanayo bangaphandle njengama-couplings axhunywe kuyo.Lokhu kuvumela ukugeleza koketshezi olubushelelezi ohlelweni ngaphandle kwemikhawulo ebalulekile.

Ezimeni lapho ubukhona be-hydrogen sulfide (H2S) bukhathaza, i-Landrill inamandla okukhiqiza amajoyinti aqhumayo aklanyelwe izinsiza ze-H2S.Lawa majoyinti okuqhuma enziwe ngezinto eziphathwa ngokushisa nezinga lobulukhuni phakathi kuka-18 no-22 HRC athobelana nezicaciso ezishiwo ku-NACE MR-0175.Ukunamathela kulawa mazinga kuqinisekisa ukumelana kwelunga emiphumeleni elonakalisayo ye-H2S futhi kugcina ubuqotho buphelele bentambo yeshubhu ezindaweni ezinothile nge-H2S.

Sekukonke, i-blast joint iyingxenye ebalulekile ekuqedeni kahle nasekukhiqizeni, enikeza ukuvikeleka nokuphila isikhathi eside kuchungechunge lweshubhu kuyilapho igcina izici zokugeleza ezifanele.
