Njengamanje, amapayipi ensimbi asetshenziswa kabanzi futhi anezinhlobo eziningi.Ukunwetshwa kwe-thermal carbon steel pipe kungenye yazo.Inezinzuzo eziningi, kodwa-ke akukhona ngaphandle kokubi.Okulandelayo incazelo eningiliziwe yezinzuzo kanye nobubi bamapayipi ensimbi anwetshiwe ashisayoabakhiqizi bepayipi lensimbi ye-carbon, ngethemba ukukusiza uqonde lo mkhiqizo.

Izinzuzo zeukwanda okushisayoipayipi lensimbi ye-carbon:

Ingacekela phansi ukwakheka kwepayipi lensimbi, icwenge usayizi wokusanhlamvu wepayipi lensimbi elinwebekayo ngokushisa, isuse amaphutha e-microstructure, yenze ipayipi lensimbi elinwebekayo lihlangane esakhiweni futhi lithuthukise izakhiwo zemishini.Lokhu kuthuthukiswa kubonakala ngokuyinhloko ekugibeleni, ukuze ipayipi lensimbi elinwebekayo lingasenayo i-isotropy ehambisanayo, futhi ama-bubbles, imifantu kanye ne-porosity ekhiqizwa inqubo yokuthulula nayo ingashiswa ngaphansi komsebenzi wokushisa okuphezulu nokucindezela okukhulu. .

Ububi beukwanda okushisayoipayipi lensimbi ye-carbon:

1. Ukucindezeleka okusalayo okubangelwa ukupholisa okungalingani.Ukucindezeleka okuyinsalela kubhekisela ekucindezelekeni kokuzilinganisa kwangaphakathi ngaphandle kwamandla angaphandle.Izingcindezi eziyinsalela ezinjalo zikhona kumapayipi ensimbi anwebekayo ezingxenyeni ezihlukahlukene eziphambanayo.Ngokuvamile, ubukhulu besigaba sensimbi yesigaba esikhulu, kukhulu ukucindezeleka okusalayo.Ukucindezeleka okusalayo kuwukulinganisa ngokwemvelo kwesigaba sokuzimela, kodwa kusenomphumela ohambisanayo ezicini zezingxenye zensimbi ngaphansi kwesenzo samandla angaphandle.Izici ezifana nokuguquguquka, ukungabi nesiphithiphithi, ukumelana nokukhathala, njll. kungase kube nemiphumela emibi.

2. Ngemuva kokunwetshwa kokushisa okushisayo, ama-non-metallic inclusions (ikakhulukazi ahlanganiswe nama-sulfide nama-oxides nama-silicates) kupayipi yensimbi yokwandisa ukushisa acindezelwe emashidini amancane, okuholela ku-delamination (interlayer).I-Delamination izolimaza kakhulu izici eziqinile zepayipi lensimbi elinwebekayo eduze kogqinsi, futhi lapho i-weld incipha, ukudabuka kwe-interlaminar kungenzeka.Ubunzima obuyingxenye ngenxa yokuncipha kokushisela ngokuvamile kuvame izikhathi eziningana lapho kutholakala khona isivuno futhi kuphakeme kakhulu kunohlobo oluthile ngenxa yomthwalo.
