Njengoba igama lisho, ipayipi lensimbi elinamandla liwuhlobo lwepayipi lensimbi elingathuthukisa ukumelana nokugqwala kwepayipi lensimbi, ngakho-ke indlela ye-zinc plating isetshenziswa ebusweni bepayipi lensimbi ukuze kuthuthukiswe impilo yepayipi lensimbi. Manje abakhiqizi abaningi ngokwengeziwe, abakhi, abathengi badinga lolu hlobo lwepayipi yensimbi hhayi nje ngenxa ye-anti-corrosion eqinile kodwa futhi nokuvikelwa kwemvelo. Namuhla, izinga lemboni liya ngokuya liqinile kakhulu kumapayipi ensimbi kungakhathaliseki ukuthi amapayipi afakwe uthayela noma ezinye izinhlobo zamapayipi. Kudingeka sihambisane nejubane lesikhathi samanje. Ngakho-ke uyazi ukuthi yiziphi izinkinga nezici ezinomthelela?
1. izici zethonya emakethe yamashubhu ensimbi
Imakethe iyashintsha kodwa zonke izinto zinezidingo kubathengi nakosonkontileka. Endabeni yokwakhiwa kwesakhiwo, amapayipi ensimbi afana nepayipi lensimbi yesikwele kudingeka afakwe uthayela ukuze kuqiniswe ukuphepha kanye nomphumela wokufaka isicelo. Ngaphandle kwalokho, ukucaciswa kwepayipi lensimbi kufanele kulungiswe ngokuvumelana nokucaciswa phansi, ngaphandle kwalokho, kuzobangela ukuchithwa kwezinsiza. Yiqiniso, ukukhethwa kwamapayipi ensimbi nakho kubalulekile futhi izindawo ezahlukene zidinga amapayipi ensimbi ahlukene. Isimo semakethe yamapayipi ensimbi sithintwa yilezi zici.
2. ukusebenzisana phakathi kweChina namazwe angaphandle
Siyazi sonke ukuthi maningi amabhizinisi eChina atshalwe yizinkampani zakwamanye amazwe. Kunjalo, maningi amaphrojekthi okwakha phesheya atshalwe eChina. Njengoba ukubambisana kwe-sino-angaphandle sekuye kwathandwa kakhulu, izinkinga ekuhwebeni kwangaphandle kosayizi wepayipi lensimbi eligoqiwe elibandayo nazo zikhona. Ukuthatha ishadi lemininingwane leshubhu lensimbi yesikwele njengesibonelo, ukusetshenziswa kwasekhaya nezangaphandle kuhlukile. Umkhiqizi wamapayipi ensimbi wasekhaya kufanele alandele imithetho yemakethe ekuhwebeni kwangaphandle ngesisekelo soshintsho olufanele. Ngaphezu kwalokho, kubalulekile futhi ukuhlukanisa ipayipi lensimbi elinamandla, eliqinile kakhulu emazweni angaphandle. Ukubambisana phakathi kweChina namazwe angaphandle kungahlala isikhathi eside uma behloniphana.
3. izidingo zemvelo
Ukungcoliswa kwemvelo kuyinkinga enkulu ebangelwa ukuthuthuka ngokushesha kwezimboni okuhlanganisa nokungcoliswa kwamapayipi ensimbi. Sonke siyazi ukuthi ipayipi lensimbi lisetshenziswa kakhulu futhi lingabonakala kwezinye izinto zokuhamba zikawoyela, amanzi kanye nophethiloli. Kodwa-ke, udoti wamakhemikhali uzoba yingozi emvelweni kanye nasemzimbeni womuntu. Abakhiqizi bepayipi lensimbi kufanele banciphise umphumela omubi ohlelweni lokuthuthukiswa.
