Ukufaneleka kwepayipi kuchazwa njengengxenye esetshenziswa ohlelweni lwamapayipi, ngokuguqula ukuqondisa, ukuguquguquka noma ukuguqulwa kobubanzi bepayipi, futhi okuhlanganiswe ngohlelo kuhlelo. Kunezinhlobo eziningi ezahlukahlukene zokufakelwa futhi ziyefana kuwo wonke amasayizi namashejuli njengepayipi.
Ukufakelwa kuhlukaniswe ngamaqembu amathathu:

Izicelo zokufakwa kweButweld
Uhlelo lokusebenzisa amapayipi usebenzisa ukufakwa kweButtweld lunezinzuzo eziningi ezingokwemvelo ngaphezu kwamanye amafomu.
Ukushiswa kwe-welding, kufanelekile ipayipi kusho ukuthi kuvuza ngokuphelele ngokuphelele;
Isakhiwo sensimbi esiqhubekayo esakhelwe phakathi kwepayipi nokufaneleka kwenezela amandla ohlelweni;
Indawo ebushelelezi yangaphakathi kanye nezinguquko eziqondiswa kancane kancane zinciphisa ukulahleka kwengcindezi kanye nesiphithiphithi futhi kunciphise isenzo sokugqwala nokuguguleka;
Uhlelo lwe-Welded lusebenzisa ubuncane besikhala.
