Amapayipi angenamthungoziyizingxenye ezibalulekile zezimboni ezihlukahlukene, kusukela kwezezimoto kuye kwezokwakha kanye nezobunjiniyela.Zinikeza indawo yangaphakathi ebushelelezi eqinisekisa ukugeleza koketshezi, amagesi, noma ezinye izinto ngaphandle kokuvinjelwa.Intengo yamapayipi angenamthungo ingahluka kakhulu kuye ngobukhulu bawo, izinga lempahla, ukujiya kodonga, nokunye.
Kumaphrojekthi ezimboni adinga amapayipi anobubanzi obukhulu ekusetshenzisweni kwengcindezi ephezulu njengezindawo zokuhluza uwoyela namapayipi egesi, insimbi engagqwali ingenye yezinto ezisetshenziswa kakhulu ngenxa yekhono layo lokumelana nokugqwala emazingeni okushisa aphakeme. Amapayipi ensimbi engenamthungo atholakala kumabanga ahlukahlukene njenge-304L/304H noma 316L futhi afika nobubanzi bodonga olusuka ku-Sch 5s ukuya ku-XXS. Intengo yamapayipi angenazihibe izoncika ebangeni elikhethiwe kanye nosayizi nenani eli-odwa ikhasimende.
Insimbi ye-carboniphinde ibe inketho ekahle yezinhlelo zokusebenza eziningi zezimboni uma kubhekwa izici zayo zamandla kuyilapho inikeza ukonga kwezindleko uma kuqhathaniswa nezinye izinsimbi ezifana nezingxube zensimbi engagqwali.Imikhiqizo yensimbi yekhabhoni inesethi yayo eyingqayizivele yezinzuzo nezingozi okufanele zicatshangelwe lapho kunqunywa ukuthi yiluphi uhlobo lwensimbi okufanele lusetshenziswe kumaphrojekthi athile ngokusekelwe ezidingweni zokusebenza uma kuqhathaniswa nemingcele yesabelomali. Kuya ngezidingo ezithile zohlelo lokusebenza ezifana nokushisela noma izici zokusebenziseka kalula zingathonya ukuthi i-carbon steel izokhethwa ngaphezu kwezinye izinsimbi uma kufika isikhathi sokunquma ukuthi hlobo luni lomkhiqizo okufanele luthengwe uma kubhekwa amapharamitha athile esabelomali i-AISI 1020 iyibanga eliyisibonelo esisodwa nje elisetshenziswa ezinhlelweni zamapayipi anomfutho ophansi lapho izakhiwo zemishini zingabaluleki kakhulu kodwa izinketho zokonga zifunwa ngaphezu kwenani eliphakeme.I-ASTM A106 Ibanga B/C.
Ekugcineni izintengo zamapayipi angenazihibe zingashintshashintsha kakhulu kuye ngesidingo semakethe ngakho-ke amakhasimende kufanele avame ukuthenga ngaphambi kokuphothula noma yimaphi ama-oda okuthenga uma kungenzeka ukuze aqinisekise ukuthi athola inani elingcono kakhulu lemali esetshenzisiwe ngokucabangela kokubili izindinganiso zekhwalithi kanye nezikhathi zokulethwa ezidingekayo ezidingweni ezithile zephrojekthi.
