Ipayipi lensimbi lisetshenziselwa ukudlulisa uketshezi kanye nempushana eqinile, ukushintshanisa ukushisa, izingxenye zemishini yokukhiqiza kanye neziqukathi, kuyimpahla yomnotho. Isakhiwo sokwakhiwa kwensimbi esine-truss yensimbi, insika nokusekelwa kwemishini, singanciphisa isisindo, songe insimbi engu-20 ~ 40%, futhi singathola ukwakhiwa kwemishini ngefektri yokukhiqiza amapayipi ensimbi. Ibhuloho lomgwaqo omkhulu alikwazi nje ukulondoloza insimbi, ukwenza lula ukwakhiwa, futhi linganciphisa kakhulu indawo ehlanganisiwe, ukonga izindleko zokutshala izimali kanye nokugcinwa.
