Izihlanganisi zetafula lamapayipi eziqondile zivame ukwenziwa ngezinto zensimbi ezibunjiwe, ezinamandla aphezulu kanye nokumelana nokugqwala. Izinto zensimbi ezibunjiwe zingavimbela ngempumelelo ilunga ukuthi lonakale noma ligqwale ngesikhathi sokusetshenziswa, futhi ziqinisekise ukusebenza okuphephile nokuthembekile kwemitha.
Ijoyinti livame ukwakhiwa umzimba wejoyinti, izihlanganisi zamapayipi kanye nezivalo, njll. Umzimba wejoyinti kanye nezivalo zamapayipi kukhiqizwa ngenqubo yokukhipha, futhi kusebenza kahle ekuvaleni kanye nokumelana nengcindezi. Izivalo zenziwe ngezinto zerabha noma zensimbi ezingagqwali ukuqinisekisa ukuvalwa okuhle kwejoyinti.
Indawo yokusetshenziswa kwe-straight pipe table joint ikakhulukazi uhlelo lwamapayipi ezimboni. Ifanelekela ukulinganisa nokulawula igesi yemvelo, igesi kaphethiloli encibilikisiwe, uphethiloli kanye namanye amagesi angaboli. Ekukhiqizweni kwezimboni, ama-straight pipe gauge joints avame ukufakwa kumapayipi noma imishini ukuze kuqoqwe futhi kuqashwe ingcindezi yoketshezi, izinga lokushisa kanye nemingcele yokugeleza. Lawa mapharamitha abaluleke kakhulu ekulawuleni nasekulawuleni inqubo yokukhiqiza, futhi i-straight pipe meter joint iqaphela ukulinganisa okunembile kwamapharamitha oketshezi ngokuxhuma imitha kanye nepayipi.
