Ukufakwa kwensimbi engagqwali kumagatsha amapayipi okuthembekile, okugeleza okushelelayo okushisayo okushisayo, ukumelana nokugqwala okungu-304/316, kanye neziphetho ezilungele ukushisela zezinhlelo zamapayipi ezimboni.

Indololwane yensimbi engagqwali ene-curvature ebushelelezi eyakhiwe ngokushisa, ukumelana nokugqwala, nokusebenza kwengcindezi ezinzile kumakhemikhali, amanzi olwandle, umoya, ukudla, namapayipi ekhemikhali.
Indololwane ye-Carbon steel engu-180-degree yezakhiwo zepayipi le-U-turn, enikeza amandla awakheke ashisayo, ukujiya kodonga olufanayo, ama-bevel alungele ukushiselwa, kanye nokumelana nengcindezi yezimboni.
