Izwi rakajairwa remajekiseni maitiro anoshandisa yakakosha makemikari mhinduro kunatsiridza kudzoreredza kweoiri, kubvisa kukuvadzwa kwekuumbwa, kucheneswa kwakavharika perforations kana maumbirwo akaturikidzana, kuderedza kana kumisa kutu, kusimudzira mafuta asina kuchena, kana kugadzirisa kuyerera kwemafuta asina kuchena.Jekiseni rinogona kupihwa nguva dzose, mumabhechi, mumatsime ejekiseni, kana dzimwe nguva mumatsime ekugadzira.
Akasarudzika ekugadzira masimba uye maitiro anobvumira Meilong Tube kugadzira iyo yakareba inoenderera inoenderera makemikari jekiseni mutsara wechubhu inowanikwa mumasimbi asina tsvina uye yakakwirira nickel alloys.Yedu refu refu tubing macoil anoshandiswa zvakanyanya kune makemikari jekiseni mu subsea uye onshore matsime.Iyo yakareba isina orbital welds iyo inoderedza mikana yekuremara uye kukundikana.Pamusoro pezvo, macoil edu ane akanyanya kuchena uye akatsetseka mukati mepamusoro akanakira majekiseni emakemikari.Macoils anopa pfupi hydraulic mhinduro nguva, yakakura kudonha simba, uye kubviswa kwemethanol permeation.
