I-Blast Joint yinxalenye ebalulekileyo ekusebenzeni kwe-oyile kunye negesi, eyilelwe ukubonelela ngokhuseleko kumtya we-tubing kunye nokunciphisa impembelelo yokhukuliseko lwangaphandle olusuka kumanzi ahambayo. Yakhiwe kusetyenziswa insimbi ephezulu kunye nenqanaba lobunzima ukusuka kwi-28 ukuya kwi-36 HRC ngokwe-NACE MR-0175.
Oku kuqinisekisa ukuhlala kwayo kunye nokuthembeka kwayo phantsi kweemeko ezinzima.
Ngokubeka ngokucwangcisekileyo i-blast joint echasene ne-perforations yomthombo okanye ngaphantsi kwe-tubing hanger ngexesha lemisebenzi ye-santi fracturing, inika umaleko owongezelelweyo wokukhusela kumtya we-tubing. Ulwakhiwo lwetyhubhu oluluqilima olunodonga olunzima lukhusela amandla okhukuliseko kwaye lunqanda umonakalo kwizixhobo zemveliso.
Ukugcina i-diameter egcweleyo yangaphakathi ye-tubing, i-joint joint blast yenzelwe ukuba ibe nobubanzi obufanayo obungaphandle njengoko i-couplings exhunywe kuyo. Oku kuvumela ukuhamba kwamanzi agudileyo kwisixokelelwano ngaphandle kwezithintelo ezibalulekileyo.
Kwiimeko apho ubukho be-hydrogen sulfide (H2S) buyinkxalabo, i-Landrill inamandla okuvelisa amalunga okuqhuma alungiselelwe ngokukodwa iinkonzo ze-H2S. Ezi zixhobo eziqhumayo zenziwa kwizinto eziphathwa ngobushushu kunye nenqanaba lobunzima phakathi kwe-18 kunye ne-22 HRC ehambelana neenkcukacha ezichazwe kwi-NACE MR-0175. Ukuthobela le migangatho kuqinisekisa ukuchasana kwe-joint kwimiphumo enobungozi ye-H2S kwaye igcina ingqibelelo yonke yentambo ye-tubing kwiindawo ezityebileyo ze-H2S.
Ngokubanzi, ukudibanisa ukuqhuma yinxalenye ebalulekileyo ekugqityweni kakuhle kunye nemisebenzi yemveliso, enikezela ukhuseleko kunye nokuphila ixesha elide kumtya wetyhubhu ngelixa ugcina iimpawu zokuhamba kakuhle.
