Emkhakheni wokwakha kanye nobunjiniyela bomphakathi, izinto ezisetshenziswayo zinomthelela omkhulu ekuqineni nasekuphepheni kwephrojekthi. Enye yezinto ezinjalo ezihlonishwa kakhulu embonini izinqwaba zamapayipi ensimbi, ikakhulukazi lawo ahlangabezana nezinga le-ASTM A252. Ukuqonda leli zinga kubalulekile konjiniyela, osonkontileka, nabaphathi bephrojekthi ngokufanayo, njengoba kuqinisekisa ukuthi izinto ezisetshenziswayo zihlangabezana namazinga athile ekhwalithi nokusebenza.
Izinga le-ASTM A252 limboza izinqwaba zamapayipi ensimbi angama-cylindrical ngokuqondile. Lezi zinqwaba zenzelwe ukusetshenziswa njengamalungu ahlala unomphela athwala imithwalo noma njengezindlu zezinqwaba zikakhonkolo ezifakwe endaweni. Lokhu kuguquguquka kubenza babe yingxenye ebalulekile ezinhlobonhlobo zezicelo zokwakha, okuhlanganisa izisekelo zamabhuloho, izakhiwo, nezinye izakhiwo ezidinga izisekelo ezijulile.
Elinye lamaphuzu abalulekile e-I-ASTM A252okujwayelekile ukugxila kwayo ezicini zemishini yensimbi esetshenziswa ezinqwabeni zamapayipi. Izinga lichaza izidingo zamandla esivuno, amandla aqinile, nobude ukuze kuqinisekiswe ukuthi insimbi ingakwazi ukumelana nemithwalo nezingcindezi engase ibhekane nazo phakathi nempilo yayo yesevisi. Ngaphezu kwalokho, izinga licacisa izindlela ezamukelekayo zokuhlola lezi zakhiwo, linikeza uhlaka lokuqinisekisa ikhwalithi.
Mayelana nokukhiqiza, izinkampani ezikhiqiza izinqwaba zamapayipi ensimbi kumele zithobele izinga le-ASTM A252 ukuze ziqinisekise ukuthi imikhiqizo yazo ithembekile futhi iphephile ukuthi ingakhiwa. Isibonelo, inkampani enempahla ephelele yezigidi ezingu-RMB 680 kanye nabasebenzi abangu-680 ikhiqiza amathani angu-400,000 amapayipi ensimbi e-spiral ngonyaka nenani eliphumayo lika-RMB 1.8 billion. Izinkampani ezinjalo zidlala indima ebalulekile ochungechungeni lokuhlinzeka, zihlinzeka ngezinto ezisezingeni eliphezulu ezihlangabezana nezindinganiso zomkhakha.
Inqubo yokukhiqiza yeinqwaba yepayipi lensimbikuhilela izinyathelo eziningi, okuhlanganisa ukukhethwa kwempahla eluhlaza, ukwakhiwa kwamapayipi kanye nokufaka isicelo sokunamathela esivikelayo. Isinyathelo ngasinye kufanele silawulwe ngokuqinile ukuze kuqinisekiswe ukuhambisana nezinga le-ASTM A252. Isibonelo, insimbi esetshenziswayo kufanele ivele kubahlinzeki abahloniphekile abanganikeza izitifiketi zokugaya ezifakazela ukuthi okokusebenza kuhlangabezana nezicaciso ezidingekayo.
Ukwengeza, indinganiso ye-ASTM A252 ihlanganisa izinqubo zokushisela nezakhiwe ezisetshenziselwa ukukhiqiza izinqwaba zamashubhu. Izindlela zokushisela ezifanele zibalulekile ekugcineni ubuqotho besakhiwo sezinqwaba ze-tubular, futhi indinganiso inikeza imihlahlandlela yokuqinisekisa ukuthi ama-welds ayenziwa ngendlela efanele futhi ahlolwe kahle.
Sekukonke, izinga le-ASTM A252 liyincazelo ebalulekile kubo bonke abasebenza embonini yezokwakha, ikakhulukazi uma kukhulunywa ngokusetshenziswa kwezinqwaba zamapayipi ensimbi. Ukuqonda izidingo zaleli zinga kusiza ukuqinisekisa ukuthi amaphrojekthi ahlala isikhathi eside futhi asebenzisa izinto ezizomelana nesikhathi. Izinkampani ezikhiqiza lezi zinto, njengalezo ezishiwo ngaphambilini, zidlala indima ebalulekile embonini ngokuhlinzeka ngemikhiqizo yekhwalithi ephezulu ehlangabezana nezindinganiso eziqinile. Njengoba amaphrojekthi wokwakha eqhubeka nokuvela, ukuhlala unolwazi lwakamuva ngamazinga afana ne-ASTM A252 kubalulekile ukuze uphumelele kulo mkhakha.
