Kungani Umugqa Wokugaya Nokukhazimulisa Wangaphakathi Ubalulekile Emapayipini Ensimbi Asebenza Kahle Kakhulu?

Ukugaya nokukhazimulisa kwangaphakathi kuyisinyathelo esibalulekile sokuqedela ekukhiqizeni amapayipi ensimbi asezingeni eliphezulu.

Le nqubo yakhelwe amapayipi asetshenziselwa izinhlelo zokuthutha uketshezi ezidinga kakhulu: ukudluliswa kwamanzi aphuzwayo, amapayipi kawoyela ongahluziwe nawoyela ohluziwe, izinto zamakhemikhali ezidlayo, udaka kanye nokuthuthwa koketshezi okuhuzulayo.

Kulezi zimo zokusebenza, umgodi wangaphakathi kufanele uhlale ubushelelezi, ungenasici futhi ulingane ngokwezilinganiso phakathi namashumi eminyaka okusebenza.

Ingaphakathi lepayipi elishisisiwe noma elishiselwe njengoba linjalo lithwala isikala sasefekthri, amaconsi okushisela, ukungalingani kobukhulu kanye nokugqwala okusele.

Ngaphansi kokugeleza okuqhubekayo, ingaphezulu langaphakathi elimaholoholo landisa ukulahleka kokungqubuzana, likhuphula ukusetshenziswa kwamandla okumpompa, futhi libamba isikala nenhlabathi okusheshisa ukugqwala kwangaphakathi.

Umugqa wokugaya nokupholisha wangaphakathi uxazulula le nkinga eyinhloko.

Usebenzisa iziteshi eziningi zamasondo okugaya ukusebenzisa umgodi wangaphakathi ukuze ube nokungalingani okufanayo nokuhlangana kwesikhungo, kususwe amaconsi okushisela, isikala sasefekthri kanye nezinkinga zangaphezulu ngokuhamba okukodwa.

Ingaphezulu langaphakathi elisuswe kahle linganciphisa ukumelana nokugeleza, lithuthukise ukunamathela kwengubo yokumboza yangaphakathi ye-epoxy / cement mortar, futhi liqinisekise ukusebenza okuzinzile kwe-hydraulic kulo lonke ipayipi.

Ezingxenyeni zensimbi ezinkulu ezigaywe ngaphakathi, le mithetho ebalulekile kufanele ilandelwe ngokuqinile:

· Ukuqondaniswa kwekhanda lokugaya okunembayo — qinisekisa ukugaya okuthinta ngokuphelele kulo lonke ubude bomgodi, kungabikho zindawo ezigwenyiwe noma ukujula okungalingani.

· Iphrofayela yobukhulu obulawulwayo — hlanganisa isidingo sephrojekthi se-Ra (ngokuvamile i-Ra 6.3–12.5 μm kumapayipi ane-lining, kucole kakhulu kusevisi ye-hydraulic/pneumatic). Ukuba makhulu kakhulu kubangela ukulahleka kokugeleza; ukuba bushelelezi kakhulu kwenza ubuhlobo be-coating buthaka.

· Ukulingana komugqa we-weld — umugqa wangaphakathi we-weld kufanele ugaywe ufane nensimbi eyisisekelo, kuqedwe i-eddy yokugeleza kanye namaphoyinti okugxila kwengcindezi.

· Ukuhlolwa kobukhulu obungaphakathi — ukuhlolwa kobubanzi nge-ultrasonic / laser ngemva kokugaya ukuqinisekisa ukuthi i-ovality kanye nokubekezelela kodonga kuhlala kungaphakathi kwesimiso.

· Ukuhlanzeka ngemva kokugaya — phendula i-steel grit nothuli ngokushesha, bese ufaka uwoyela wokuvimbela ukugqwala noma ugoqe ukuze ugcine, ukuvimbela ukugqwala okusheshayo endaweni esanda kugaywa.
