Emhlabeni wokukhiqizwa kwezimboni, ikakhulukazi emkhakheni wezamandla, ikhwalithi yama-welds ekukhiqizeni amapayipi ibalulekile. Lokhu kuyiqiniso ikakhulukazi kumapayipi egesi, lapho ubuqotho be-weld bungase busho umehluko phakathi kokuphepha nenhlekelele. Embonini yethu eseCangzhou, esiFundazweni sase-Hebei, siyayiqonda indima ebalulekile edlalwa ikhwalithi yokushisela ekuqinisekiseni ukwethembeka nokuphepha kwemikhiqizo yethu. Inkampani yethu yasungulwa ngo-1993 futhi isikhule yafinyelela endaweni engamamitha-skwele angu-350,000, impahla ephelele yezigidi ezingu-RMB 680, kanye nabasebenzi abazinikele abangama-680.
Esinye sezici ezibalulekile okufanele zicatshangelwe lapho i-arc welding amapayipi egesi yemvelo uhlobo lobuchwepheshe bokushisela obusetshenziswayo. Ngobaipayipi elihlanganisiwe elivunguzayo, indlela evame kakhulu i-submerged arc welding (SAW) inqubo. Le nqubo ithandwa kakhulu ngekhono layo lokukhiqiza ama-welds aqinile, aqinile, asezingeni eliphezulu. Inqubo yokushisela i-arc engaphansi kwamanzi ihilela ukwakheka kwe-arc phakathi kwe-electrode ephakelwa ngokuqhubekayo kanye nendawo yokusebenza, ecwiliswa ngaphansi kongqimba lwe-granular flux. Lokhu akuvikeli kuphela i-weld ekungcoleni, kodwa futhi kuthuthukisa ikhwalithi ye-weld ngokuhlinzeka nge-arc ezinzile nokunciphisa i-spatter.
Ukubaluleka kweiphayiphiikhwalithi yokushisela ayikwazi ukweqiwa. Ekuthuthweni kwegesi yemvelo, noma yikuphi ukwehluleka kokushisela kungaholela emiphumeleni eyinhlekelele, okuhlanganisa ukuvuza, ukuqhuma nokulimala kwemvelo. Ngakho-ke, ukuqinisekisa ukuthi izinqubo zethu zokushisela zihlangabezana namazinga aphezulu kuyinto ehamba phambili. Ukuzibophezela kwethu kukhwalithi kuqala ngokukhethwa kwezinto ezingavuthiwe futhi kuyaqhubeka kuzo zonke izigaba zenqubo yokukhiqiza, okuhlanganisa ukuhlolwa okuqinile nokuhlolwa kwamashisela.
Esikhungweni sethu saseCangzhou, sisebenzisa ubuchwepheshe obuphambili nochwepheshe abanamakhono ukuze siqinisekise ukuthi inqubo yethu yokushisela i-arc engaphansi kwamanzi ikhiqiza imiphumela emihle. Ithimba lethu liqeqeshelwe ukuqapha ngokucophelela futhi lilawule imingcele yokushisela, liqinisekise ukuthi i-weld ngayinye ihlangabezana nezidingo eziqinile ezishiwo izindinganiso zomkhakha. Lokhu kunakekela emininingwaneni akuthuthukisi nje kuphela ubuqotho besakhiwo samapayipi ethu egesi, kodwa futhi kuzuza ukwethenjwa amakhasimende ethu, athembele emikhiqizweni yethu ukuze kuthuthwe amandla ngendlela ephephile futhi ephumelelayo.
Ukwengeza, ikhwalithi ye-pipeline weld ithinta ngokuqondile ukusebenza kanye nempilo yepayipi. Ikhwalithi ephezulutube weldukunciphisa amathuba okuba nezinkinga zokulungisa futhi andise impilo yepayipi, ekugcineni konge izindleko kumakhasimende ethu. Embonini lapho ukwethembeka kubalulekile, ukutshala imali kukhwalithi ephezulu yokushisela kungaphezu nje kokukhetha; kuyisidingo.
Sengiphetha, ukubaluleka kwekhwalithi ye-welding yamapayipi ekukhiqizeni amapayipi egesi yemvelo akukwazi ukushaywa indiva. Njengomkhiqizi ohamba phambili embonini, ukuzibophezela kwethu ekusebenziseni ubuchwepheshe bokushisela obusezingeni eliphezulu obufana nokushisela i-arc ngaphansi kwamanzi kanye nokugxila kwethu ekulawuleni ikhwalithi kusenza sibe uzakwethu owethembekile wamakhasimende ethu. Njengoba sinesipiliyoni seminyaka engaphezu kwamashumi amathathu nabasebenzi abazinikele, siyaqhubeka nokubeka phambili ukuphepha nokuthembeka kwemikhiqizo yethu, siqinisekisa ukuthi sihlangabezana nezidingo zemboni yamandla ethuthukayo. Njengoba siqhubekela phambili, sihlala sigxilile emsebenzini wethu wokuhlinzeka ngamapayipi egesi emvelo asezingeni eliphakeme kakhulu, ngoba uma kuziwa ekuthuthweni kwamandla, ikhwalithi ayibalulekile nje kuphela; kubalulekile.
