Ipayipi elihlanganisiwe lensimbi engagqwali liwumsebenzi omusha owenziwe ngensimbi engagqwali kanye nensimbi yesakhiwo se-carbon ehlanganiswe ngokuhambisana nokucindezela okungabhubhisi.Inokumelana nokugqwala nokumelana nokugqokwa kwensimbi engagqwali kanye nokubukeka okuhle nokuhle, kanye namandla amahle okugoba nomthelela wokumelana nomthelela we-carbon steel.Ngokuhambisana nezimiso zikazwelonke zokongiwa kwamandla kanye nokuthandwa kwabantu.

Iinsimbi engagqwali eyinhlanganisela ipayipiinokuqukethwe okuphezulu kwezobuchwepheshe, okokusebenza okunembile, ubuchwepheshe obuphambili, ikhwalithi yomkhiqizo ezinzile, nokulawula ikhompuyutha okuzenzakalelayo.Imikhiqizo isetshenziswa kakhulu ekwakhiweni kwemisebenzi yomphakathi kamasipala, isakhiwo sensimbi, ukwakhiwa kwegridi, i-petroleum kanye ne-petrochemical, izikhungo zikamasipala, imigwaqo yokuqapha imigwaqo kanye nebhuloho, ukwakhiwa kobunjiniyela bomgwaqo onguthelawayeka;ukwakhiwa kobunjiniyela bomhlobiso wezakhiwo;izindawo zezemidlalo ezobunjiniyela zokwakha igridi yethrafikhi, inethiwekhi yokuhlukanisa ujantshi, imihlobiso yokwakha, amalambu omgwaqo, izimpawu zokuma, amagridi ensimbi, ifenisha, ukukhiqizwa kwezimoto nezikebhe, amanethiwekhi amapayipi asemadolobheni, ukuthuthwa kukawoyela negesi, obhampa bezithuthuthu, izinsimbi zokomisa, izibambo zamabhayisikili, njll. .
