Ukufakwa kwamapayipi kuchazwa njengengxenye esetshenziswa ohlelweni lwamapayipi, ukushintsha isiqondiso, ukuhlanganisa amagatsha noma ukushintsha ububanzi bamapayipi, futhi ehlanganiswa ngomshini ohlelweni. Kunezinhlobo eziningi ezahlukene zokufakwa futhi ziyafana kuzo zonke izilinganiso namashejuli njengepayipi.
Izinhlobo zokufakelwa zihlukaniswe ngamaqembu amathathu:
Izithako ze-Buttweld (BW) ezinobukhulu bazo, ukubekezelelana kobukhulu njll. okuchazwe ezindinganisweni ze-ASME B16.9. Izithako ezimelana nokugqwala ezilula zenziwe nge-MSS SP43.
Ukufakwa kwe-Socket Weld (SW) Class 3000, 6000, 9000 kuchazwe ezindinganisweni ze-ASME B16.11.
Izingxenye ezinemicu (THD), ezinezikulufo ze-Class 2000, 3000, 6000 zichazwe ezindinganisweni ze-ASME B16.11.
Ukusetshenziswa kwe-Buttweld Fittings
Uhlelo lwamapayipi olusebenzisa izinto zokubopha ezigoqekayo lunezinzuzo eziningi ezingokwemvelo kunezinye izinhlobo.
Ukushisela ukufakelwa kwepayipi kusho ukuthi akuvuzi unomphela;
Isakhiwo sensimbi esiqhubekayo esakhiwe phakathi kwepayipi nokufakwa kwensimbi sinezela amandla ohlelweni;
Ubuso obubushelelezi bangaphakathi kanye nezinguquko eziya kancane kancane kunciphisa ukulahlekelwa yingcindezi kanye nokuxokozela futhi kunciphise isenzo sokugqwala nokuguguleka;
Uhlelo oluhlanganisiwe lusebenzisa isikhala esincane kakhulu.
