Ukufakwa kwepayipi kuchazwa njengengxenye esetshenziswa ohlelweni lwamapayipi, ekushintsheni indlela, igatsha noma ukushintsha ububanzi bepayipi, futhi ehlanganiswe ngomshini ohlelweni. Kunezinhlobo eziningi ezahlukene zokufakwa futhi ziyafana kuwo wonke amasayizi namashejuli njengepayipi.
Ukufakwa kuhlukaniswe ngamaqembu amathathu:
Ukufakwa kwe-Butt weld okunobukhulu, ukubekezelelana kobukhulu nokunye okuchazwe kumazinga we-ASME B16.9. Izinto ezimelana nokugqwala kwesisindo esikhanyayo zenziwe ku-MSS SP43.
Ukufakwa kwe-Socket Weld Class 3000, 6000, 9000 kuchazwe kumazinga we-ASME B16.11.
Ukufakwa okunentambo, okukrufulwe Ikilasi 2000, 3000, 6000 kuchazwe kumazinga we-ASME B16.11.
Izicelo zokufakwa kwe-Butt weld
Isistimu yamapayipi esebenzisa okokufaka kwe-butt weld inezinzuzo eziningi zemvelo ngaphezu kwezinye izinhlobo.
Ukushisela into efakwa epayipini kusho ukuthi ayivuzi unomphela;
Isakhiwo sensimbi esiqhubekayo esakhiwe phakathi kwepayipi nokufaka sinezela amandla ohlelweni;
Ingaphakathi elibushelelezi kanye nezinguquko eziqondisayo kancane kancane kunciphisa ukulahleka kwengcindezi kanye nesiyaluyalu futhi kunciphise isenzo sokugqwala nokuguguleka;
Isistimu eshiselwe isebenzisa ubuncane besikhala.
I-Butt weld Carbon Steel kanye ne-Stainless Steel Pipe Fittings
Ukufakwa kwepayipi le-Buttweld kuhlanganisa irediyasi endeindololwane, kugxileisinciphisi, izinciphisi ze-eccentric kanyeteenjll. Izinsimbi zokushisela i-Butt stainless steel kanye ne-carbon steel fittings ziyingxenye ebalulekile yesistimu yamapayipi emboni ukuze ushintshe indlela, ucishwe noma uhlanganise imishini ohlelweni. Ukufakwa kwe-Buttweld kuthengiswa ngosayizi bamapayipi okuzisholo ngohlelo olushiwo lwamapayipi. Ubukhulu be-BW fitting nokubekezelela kuchazwa ngokwezinga ngalinye le-ASME B16.9.
Izinqamu ezishiselwe ukufakwa kwepayipi okufana ne-carbon steel nensimbi engagqwali kunikeza izinzuzo eziningi uma kuqhathaniswa nokufakwa kwe-threaded kanye ne-socketweld. Okukamuva kutholakala kuphela kufika kusayizi ongamayintshi angu-4 kanti okokufaka kwe-butt weld kutholakala ngosayizi osuka ku-½” ukuya ku-72". Ezinye zezinzuzo zokufakwa kwe-weld yilezi;
Ukuxhumeka okushiselwe kunikeza uxhumano oluqinile
Isakhiwo sensimbi esiqhubekayo sinezela emandleni esistimu yamapayipi
Ukufakwa kwe-butt-weld enamashejuli wamapayipi afanayo, kunikeza ukugeleza okungenamthungo ngaphakathi kwepayipi. I-weld yokungena egcwele futhi efakwe kahle i-LR 90 Elbow, Reducer, Concentric reducer njll. inikeza ushintsho kancane kancane ngokufaka amapayipi ashiselwe.
Konke ukufakwa kwepayipi le-buttweld kuneziphetho ezigobile njengokujwayelekile kwe-ASME B16.25. Lokhu kusiza ekudaleni i-weld yokungena ngokugcwele ngaphandle kokulungiselela okwengeziwe okudingekayo kokufakwa kwe-butt weld.
Ukufakwa kwepayipi le-butt weld kuvame ukutholakala ku-carbon steel, insimbi engagqwali, i-nickel alloy, i-aluminium kanye nezinto ezikhiqiza kakhulu. Ukufakwa kwepayipi lensimbi yensimbi enesivuno esiphezulu kutholakala ku-A234-WPB, A234-WPC, A420-WPL6, Y-52, Y-60, Y-65, Y-70. Konke ukufakwa kwamapayipi e-WPL6 kukhishiwe futhi kukhona i-NACE MR0157 ne-NACE MR0103 ehambisanayo.
