ERW ipayipi weld contour shape
Ngokusho kwamazinga e-API SPEC 5L, imboni yokukhiqiza yasekhaya eminingi ngesikhathi sokuhlolwa kwe-SAW pipe weld tensile, imvamisa igcina ukuqiniswa kwe-weld, ukuhlolwa okuqondile okuqinile okuvela ekuhlolweni okungavamile ukuphulwa kwesimo sokushisela.Isizathu esiyinhloko singabangwa ukuba khona kokuqiniswa kwe-weld.Ipayipi le-SAW, elishiwo ngaphezu kokuphezulu noma ukuqinisa ukuphakama, ngenhloso yokwandisa ubukhulu bendawo yokushisela, futhi kuthuthukise amandla esakhiwo se-weld, amandla wendawo weld (amandla esakhiwo jikelele) kunamandla esisekelo. izingxenye zensimbi.
Ireferensi ye-SAW pipe weld Ukuqinisa indima enenzuzo ekushiseleleni ipayipi le-ERW ihlose ukuminyanisa, eduze nendawo yokushisela ukwenza ugqinsi olukhulu kunobukhulu bezinto eziyisisekelo, ludlulele endaweni eqinisayo ye-weld ethinteke ukushisa, bese ngaphakathi. ukwakheka kwe-burr yokushisela ilingane ngokuphelele, kwakha isifunda senguquko esimagagasi esibushelelezi ukuze kuthuthukiswe amandla esakhiwo sendawo yokushisela phakathi kwesisekelo sensimbi nokushisela kwensimbi.Phakathi naleso sikhathi, njengoba ukushuba kwamapayipi okushisela kunokubekezelelana okukhulu, ngisho nokuguquguquka kwesistimu ngenxa ye-glitch yangaphakathi, okuholela ezingeni elithile lokushisela kwe-groove, ngeke kubangele ukwehla okukhulu kwamandla e-weld.Ngaphezu kwalokho, i-weld kanye nesisekelo sensimbi inguquko ebushelelezi, ukuhlolwa kwe-ultrasonic ye-weld akubangeli ukwanda kwamanga kwamanga.
Klwepha ama-welds angaphakathi abushelelezi kakhulu, i-weld kanye ne-base metal transition bushelelezi kakhulu.Ngokuvamile ugqinsi lwamapayipi ensimbi luwu-11.9mm, ububanzi obuwugqinsi bokushisela ama-extrusion ngokuvamile busukela cishe ku-25mm kuya kunoma yiluphi uhlangothi lwe-weld ngayinye, ingxenye yokushisela ngemva kokususwa kwe-burr kunezinye izingxenye zogqinsi oluyisisekelo olucishe lube ngu-10%.Ugqinsi oluncane lwepayipi, khama uhla oluwugqinsi lungase luncishiswe, kodwa ingxenye yezingxenye ezijiyile zokushisela zokulawula jikelele 10% wesisekelo sezinto ezibonakalayo.
