Ngokuthuthuka okuqhubekayo kwenqubo yezimboni zomhlaba wonke, isidingo seamashubhu ensimbi ye-carbon (cs tube)liyakhula unyaka nonyaka. Njengezinto ezisetshenziswa kakhulu zamapayipi, amashubhu ensimbi e-carbon asetshenziswa kabanzi emikhakheni eminingi njengamandla, ukwakhiwa, kanye nezimboni zamakhemikhali. Kodwa-ke, lapho kuthengwa amashubhu ensimbi ye-carbon, kudingeka sinake izinto ezithile ezibalulekile ukuze siqinisekise ukuthi izinga nokusebenza kwamapayipi ensimbi athengiwe kuzohlangabezana nokulindelwe. Lesi sihloko sizokwethula kwezinye izinto ezidinga ukunakwa lapho uthenga amashubhu ensimbi ye-carbon.

Okokuqala, kubaluleke kakhulu ukukhetha impahla efanele. Ukukhethwa kwe-carbon steel tube material kuncike endaweni yokusetshenziswa kwayo kanye nezidingo. Ngokuvamile, amashubhu e-carbon steel afaneleka ezindaweni ezivamile zezimboni, kodwa kwezinye izindawo ezikhethekile, njengezindawo zasolwandle noma izindawo zokugqwala kwamakhemikhali, kuyadingeka ukusebenzisa izinto ezinokumelana nokugqwala okungcono, njengeamashubhu ensimbi engagqwali. Ngakho-ke, kuyadingeka ukucacisa izidingo zezinto ezibonakalayo ngaphambi kokuthenga bese ukhetha ithubhu ye-carbon steel efanelekile.

Okwesibili, ukukhetha ngokucophelela abahlinzeki nakho kubalulekile. Ukukhetha umphakeli ohlonishwayo nonolwazi kungaqinisekisa ukuthengwa kwamashubhu ensimbi ensimbi ekhabhoni enokwethenjelwa. Lapho ukhetha umphakeli, ungabheka iziqu zakhe, okokusebenza kokukhiqiza, amakhono obuchwepheshe kanye nesevisi yangemuva kokuthengisa. Ngesikhathi esifanayo, ungafunda mayelana nekhwalithi yomkhiqizo womphakeli nesimo sengqondo sesevisi ngokuthintana namarekhodi omlando okwenziwa komsebenzi kanye nokuhlola kwamakhasimende. Ngokubambisana nabahlinzeki abathembekile kuphela lapho ungagwema khona ukuthenga imikhiqizo yekhwalithi ephansi noma ukuhlangabezana nesevisi engeyinhle ngemva kokuthengisa.

Futhi, intengo akuyona ukuphela kokucatshangelwa. Nakuba intengo iyindaba ekhathaza kakhulu abathengi, lapho uthenga amashubhu e-carbon steel, umuntu akufanele agxile kuphela ngentengo futhi anganaki ikhwalithi nokusebenza komkhiqizo. Amanani aphansi ngokuvamile asho ikhwalithi yomkhiqizo engathembekile. Ngakho-ke, lapho uthenga amapayipi ensimbi, ibhalansi phakathi kwentengo nekhwalithi kufanele kucatshangelwe ngokuphelele. Kuphela ngokukhetha imikhiqizo engabizi kakhulu, okungukuthi, izinga eliphezulu le-carbon steel amapayipi namanani anengqondo, singakwazi ukuhlangabezana kangcono nezidingo zephrojekthi.

Ngaphezu kwalokho, kubalulekile futhi ukuba nokulawula okuqinile phezu kwenqubo yokuthenga. Ngaphambi kokuqala ukuthengwa kwempahla, kuyadingeka ukucacisa izidingo, ukwenza uhlelo lokuthenga, nokuxhumana ngokugcwele nomphakeli. Qiniseka ukuthi inkontileka yokuthenga iqukethe ukucaciswa okucacile, inani, isikhathi sokudiliva nokunye okuqukethwe okubalulekile ukuze ugweme izingxabano ezilandelayo. Ngemuva kokuthola izimpahla, ukuhlolwa kufanele kwenziwe ngokuhambisana ngokuqinile nezidingo zenkontileka ukuze kuqinisekiswe ukuthi amapayipi ensimbi athengiwe ahlangabezana nezidingo. Ukwengeza, kuyadingeka futhi ukwenza ukuhlolwa kokusebenza kwabahlinzeki ngezikhathi ezithile ukuze kuqinisekiswe ikhwalithi yesevisi kanye nekhwalithi yomkhiqizo wabahlinzeki ohlelweni lokulethwa.

Okokugcina, isevisi efika ngesikhathi ngemva kokuthengisa iyingxenye ebalulekile yenqubo yokuthengwa kwepayipi lensimbi ye-carbon. Enqubweni yokusebenzisa amashubhu ensimbi ye-carbon, akunakugwenywa ukuthi ezinye izinkinga zizohlangana, njengokuguga kwamapayipi nokuvuza. Umphakeli onomthwalo wemfanelo kufanele anikeze isevisi efika ngesikhathi ngemva kokuthengisa ukuze axazulule izinkinga abasebenzisi abahlangabezane nazo ngesikhathi sokusetshenziswa. Ungabhekisela ekuhlolweni kwabasebenzisi besikhathi esidlule kanye nokuzibophezela kwesevisi komphakeli ukukhetha umphakeli onganikeza isevisi ephelele nangesikhathi sangemva kokuthengisa.

Ngamafuphi, kunezici eziningi okufanele zicatshangelwe lapho uthenga amashubhu ensimbi ye-carbon. Ukukhethwa okufanele kwezinto zokwakha, ukukhethwa kwabahlinzeki abahloniphekile, ibhalansi phakathi kwentengo nekhwalithi, ukulawula okuqinile kwenqubo yokuthengwa kwempahla, nokugcizelela isevisi yangemva kokuthengisa kuyizihluthulelo zokuqinisekisa ukuthi amashubhu ensimbi ekhabhoni athengiwe angakwazi ukuhlangabezana nezidingo zekhwalithi. Ngethemba ukuthi ukwethulwa kwalesi sihloko kungakusiza wenze izinqumo ezingcono zokuthenga amashubhu ensimbi ye-carbon.
