Mapombi epombi dzemafuta anowanzo machubhu esimbi, ayo akabatanidzwa newelding uye flanges nemimwe michina yekubatanidza ine mapaipi akareba, uye mavharuvhu anoshandiswa kuvhura nekuvhara kudzora uye kuyerera.Pombi yemafuta inonyanya kuve neisothermal yekufambisa, yekufambisa yekudziya uye inoteedzana yekufambisa uye humwe tekinoroji yekufambisa.Corrosion yepombi uye nzira yekudzivirira kuora ndeimwe yenzira dzakakosha dzekuchengetedza pombi.Nekuda kwekuti oiri iyi yaive nesarufa neasidhi, uye pombi yakafumurwa mumhepo nemvura inonaya, pombi yacho iri nyore kuita ngura.Pipeline corrosion inonyanya kuve nemhando dzinotevera: simbi yeokisijeni corrosion inokonzerwa nemusimboti we galvanic cell;Kuora kweHydrogen evolution nekuda kwekunaya kweasidhi kunokonzerwa nemasarufidhi ane acid yakanyanyisa (sulfur dioxide nehydrogen sulfide) pamusoro pepombi;Carbon dioxide acid corrosion inokonzerwa nekunaya kwemhepo;Utachiona hwehutachiona hunokonzerwa nehutachiona hunokwanisa kuisa sulfate pamusoro pepombi uye kuora kunokonzerwa nemvura mupombi.
Iyo pombi inoshandiswa pamapombi emafuta inonyanya kuvepa kabhoni simbi pombi, iyo inogona kukamurwa kuita seamless simbi pombi uye welded simbi pombi maererano kwayo kugadzira.Seamless simbi pombi ine hunhu hwekusimba kwepamusoro, kutaurwa kwakawanda, saka inokodzera zvigadzirwa zvemafuta ekuora kana tembiricha yakakwira.Seamless simbi pombi yakakamurwa inopisa akakungurutswa uye kutonhora akakweva maviri marudzi.Nekuti inotonhora yekudhirowa maitiro inokonzeresa kuomarara kwezvinhu, zvinodikanwawo kuita zvinoenderana nekupisa kurapwa zvinoenderana nekushandiswa chaiko kwepombi.Welded simbi pombi inogona kupatsanurwa mumarudzi maviri: musono simbi pombi uye akadonha welded pombi.Nekuda kwemaitiro eiyo kabhoni simbi pombi, rudzi urwu rwesimbi pombi iri nyore kuita brittle pane yakaderera tembiricha, saka inonyanya kukodzera kune yakajairika tembiricha pombi, tembiricha yekushandisa yepombi haifanire kudarika 300 degrees Celsius, kazhinji kutaura, tembiricha yekushandiswa kweyakajairwa kabhoni simbi pombi iri pakati pe0 ne300 madhigirii Celsius.Kana kushandiswa kwemhando yepamusoro kabhoni simbi pombi, tembiricha siyana uye kuzorora - 40 kusvika 450 madhigirii Celsius.
