Njengoba kuvunywa kahle, kusukela ekusungulweni kwensimbi, abenzi bensimbi baye bakhiqiza amamaki ahlukene ensimbi ngokusekelwe kwezicelo. Lokhu kwenziwa ngokushintsha inani lekhabhoni. Namuhla, i-carbon steel pipe iyilungu elilodwa elidumile lamapayipi ensimbi ekusetshenzisweni okuhlukahlukene. Ngokuvamile, izindlela zokupheka zensimbi zinengxenye yesisindo sekhabhoni ebangeni lika-0.2% kuya ku-2.1%. Ukuze kuthuthukiswe ezinye izakhiwo zensimbi eyisisekelo, izingxube zingase futhi zihlanganisa i-chromium, i-manganese, noma i-Tungsten. Kodwa ingxenye yalezi zinto ayicacisiwe.
Ipayipi lensimbi ye-Carbon livame ukusetshenziswa emisebenzini ehlukahlukene ngoba liqinile futhi liphephile. Izinto zokwakha ngaphansi komhlaba zingase zibe sengozini yokubola kanye nezinambuzane. Insimbi ngeke ibole futhi ayingenwa yizinambuzane ezinjengomuhlwa. Insimbi nayo ayidingi ukuphathwa ngezivimbelakuvunda, izibulala-zinambuzane noma iglue, ngakho iphephile ukuyiphatha nokusebenza nxazonke. Njengoba insimbi ingashi futhi yenza kube nzima ukuba umlilo ubhebhetheke, kuhle ukusebenzisa ipayipi lensimbi ye-carbon kumapayipi ensimbi esakhiwo lapho wakha amakhaya. Izakhiwo zohlaka lwensimbi zimelana kakhulu nezinhlekelele zemvelo njengeziphepho, iziphepho, umbani, nokuzamazama komhlaba. Ngaphezu kwalokho, ipayipi le-carbon steel limelana kakhulu nokushaqeka nokudlidliza. Umfutho wamanzi oguquguqukayo noma ingcindezi yokushaqeka evela esando samanzi ayinawo umthelela omncane ensimbi. Izimo zethrafikhi ezisindayo namuhla zibeka ingcindezi enkulu ezisekelweni zemigwaqo. Ipayipi lensimbi ye-Carbon alinakunqamuka kwezokuthutha kanye nesevisi, futhi ngenxa yalesi sizathu kulungile ukubeka amapayipi amanzi ngaphansi kwemigwaqo.
Kunoma yikuphi ukucindezela okunikezwayo, amapayipi ensimbi e-carbon angenziwa abe mncane kakhulu kunamapayipi enziwe kwezinye izinto, ngakho-ke anomthamo omkhulu wokuthwala kunamapayipi ezinye izinto ezinobubanzi obufanayo. Futhi amandla angenakuqhathaniswa amapayipi ensimbi akhulisa ukuphila isikhathi eside futhi anciphisa isidingo sokushintshwa kanye nokulungiswa. Abakhiqizi bamapayipi ensimbi bangakhiqiza amapayipi ngezilinganiso eziningi, ukusuka ngaphansi kwe-intshi ukuya ngaphezu kwamamitha amahlanu. Zingagotshwa futhi zenziwe ukuze zigobe futhi zilingane noma kuphi lapho zidinga khona. Amalunga, ama-valve nokunye ukufakwa kutholakala kabanzi ngamanani amahle.
Ipayipi lensimbi elithambile litholakala ngezimo ezihlukahlukene zesakhiwo ezishiselwa kalula zibe ipayipi noma ishubhu futhi njll. Eziningi zazo kulula ukulenza, zitholakale kalula, futhi zibiza kancane kunezinye izinsimbi eziningi. Ezindaweni ezivikelwe kahle, isikhathi sokuphila sepayipi lensimbi elithambile yiminyaka engama-50 kuya kweyi-100. Ngokungafani nepayipi lensimbi elinekhabhoni ephezulu, ipayipi lensimbi elithambile linokuqukethwe kwekhabhoni okungaphansi kuka-0.18%, ngakho lolu hlobo lwepayipi lushiselwa kalula kuyilapho ezinye izinhlobo zamapayipi ensimbi enekhabhoni ephezulu, njengepayipi lensimbi engagqwali, elidinga amasu akhethekile ukuze weld kahle impahla. Namuhla, ipayipi lensimbi elithambile liye lasetshenziswa kumapayipi amaningi emhlabeni, ngoba alishiselwa kalula nje libe endaweni eguquguqukayo kodwa futhi lingagwema ngandlela-thile ukuqhekeka nokuphuka ngaphansi kwengcindezi.
