Kumaphakheji we-Octal Pipe, ngokuvamile senza ukufakwa ngesitejiUhlu lomugqa we-ISO(usayizi/ishejuli/izinto), ukuze ithimba lokushisela likwazi ukukhetha indololwane/isethi ye-tee elungile nge-spool ngayinye ngaphandle kokuxuba izindonga.

I-Pipe spool prefabrication yama-skid e-modular (ama-welds aphindaphindayo, ukubekezelelana okuqinile):

Izitolo ze-Skid zinamakhulu amajoyinti aphindaphindiwe-ama-concentric reducers, caps, tees, kanye-namandololwane erediyasi amafushane{{0}lapho ishejuli eyodwa engalungile ingase isebenze kabusha kuyo yonke inqwaba. Empeleni, ubungozi buwushintsho "oluncane-kuya{3}}ukujiya" oluphoqa ipharamitha ukuthi ishintshe phakathi-nokukhiqiza okunensayo. I-Octal Pipe isekela ukwenziwa kwe-skid ngokuqondisa i-PO kuyeI-NPS/SCH (noma i-OD×WT)kanye nokuletha okokufakwayo okumaka okucacile kanye{0}}nephakethe lokukhululwa elinemephu eningi, ukuze ama-spools ahlale engaguquki ukusuka ku-weld yokuqala ukuya ku-hydrotest yokugcina.

Ukumuncwa kwepompo / kuyasebenza inqubo (umumo-ukufakwa okuzwelayo):

Eziteshini zokupompa kanye namayunithi okucubungula,ama-eccentric reducersasetshenziswa ngokuqondile ukugwema amaphakethe omoya nokugcina ukumunca okuzinzile-ngokuvamileifulethi-phezulu-phezulu (FOT)emigqeni yokumunca evundlile, kanye nezinciphisi/ama-tee aqondile asetshenziselwa ukugcina imisele yokudonsa amanzi. Ubuhlungu bangaphambili akusona "isinciphisi esikhona," ukuthi isinciphisi sifika ngaphandle kokuma kuchaziwe, ngakho ithimba lenkundla liyiphendula kabi futhi kamuva lijahe ukudlidliza/i-cavitation noma izinkinga zokukhipha amanzi. I-Octal Pipe ivamise ukuqinisekisa imfuneko yokuncishiswa kokuma (FOT/FOB) ngesikhathi sokucaphuna ukuvimbela lokho kulungiswa kwesayithi okugwemekayo.

-izihloko zensiza yezinga lokushisa eliphezulu (i-steam, ukushisa{1}}ukudluliswa, ukuxhumana kwe-heater):

Lawa maphakheji athembela kakhulu kuzinciphisi, izigqoko, nezindololwane okufanele zifane neshejuli yamapayipi engxubevange kanye nezimo zokwelashwa{0}}zokushisa. Ukugxila kokuhlola kuvamise ukubaukulandelela okubonakalayo + ukushisa-ubufakazi bokwelapha + ububanzi be-NDTngoba abanikazi abafuni ukufakwa okungabhaliwe kunhlokweni okuzojikeleza ngokushisa iminyaka. I-Octal Pipe ivamise ukuhambisa izindawo ezilingana nengxubevange enobufakazi bokukhululwa obufakwe kumamephu ukuze ukuhlolwa komnikazi kusule inqwaba ngaphandle kwamaphoyinti okubamba.
