Ukufakelwa kwepayipi kuchazwa njengenxalenye esetyenziswa kwinkqubo yepayipi, ekutshintsheni icala, ekwandiseni okanye ekutshintsheni ububanzi bepayipi, kwaye edityaniswe ngoomatshini kwinkqubo. Kukho iintlobo ezininzi ezahlukeneyo zokufakelwa kwaye ziyafana kuzo zonke iisayizi kunye neeshedyuli njengombhobho.
Izixhobo zokufakelwa zahlulwe zibe ngamaqela amathathu:
Izixhobo zeButtweld (BW) ezinobukhulu, ukunyamezelana kobukhulu njl. njl. zichazwe kwimigangatho ye-ASME B16.9. Izixhobo ezikhaphukhaphu ezingamelani nokugqwala zenziwe kwi-MSS SP43.
Izixhobo zeSocket Weld (SW) zeClass 3000, 6000, 9000 zichazwe kwimigangatho ye-ASME B16.11.
Izixhobo ezinemisonto (THD), ezinezikrufu zeClass 2000, 3000, 6000 zichazwe kwimigangatho ye-ASME B16.11.
Usetyenziso lweZixhobo zeButtweld
Inkqubo yokufakelwa kwemibhobho esebenzisa izixhobo zokufakelwa kwe-buttweld ineengenelo ezininzi ezingokwemvelo kunezinye iindlela.
Ukuwelda isihlanganisi kumbhobho kuthetha ukuba ayivuzi ngonaphakade;
Isakhiwo sesinyithi esiqhubekayo esenziwe phakathi kombhobho kunye nokufakelwa kombane songeza amandla kwinkqubo;
Umphezulu ongaphakathi ogudileyo kunye notshintsho oluhamba kancinci kancinci lunciphisa ukulahleka koxinzelelo kunye nokuxinana kwaye lunciphise isenzo sokugqwala kunye nokukhukuliseka;
Inkqubo edibeneyo isebenzisa ubuncinci besithuba.
