Umehluko phakathi kwepayipi lokunciphisa elishisayo kanye nepayipi lensimbi ye-LSAW linamaphuzu amabili alandelayo:
1, Okuholela ekwehlukeni kwekhwalithi yomkhiqizo ngenxa yezinqubo ezihlukene, ukunciphisa ukunwebeka okushisayo nakho kwenze inqubo ngemva kwenqubo yokushisela imvamisa ephezulu engatholakali ipayipi lensimbi ye-lsaw —— I-Longitudinal awekho umugqa ocacile ngaphakathi nangaphandle kwama-burrs. Ukuba khona kwe-Burr kuzothinta uketshezi lwe-tube - ukugeleza, i-burr ivimbe ukugeleza okuvamile koketshezi, okuholela ku-whirlpool. Ngokwemigomo ye-fluid mechanics, i-welding kufanele ikhulise ukucindezelwa kwendawo, ukungaqhubeki kwenza ukuphepha kwepayipi kuncishiswe kakhulu, ukunwebeka okushisayo kunciphisa inqubo yokukhiqiza insimbi - kucatshangelwa ngokugcwele ukuba khona kwengozi ye-burrs, ukunciphisa ukukhishwa kwe-burr, okwenza kube okufanayo. ukujiya, akukho mehluko ekubukekeni nokungenamthungo. Ngakho-ke ngokwaleli phuzu lokubuka, amapayipi anciphisa ukunwebeka ashisayo nawo aqedele uguquko ngaphandle komthungo.

I-2, ikhwalithi ye-Weld inquma ngokuqondile ikhwalithi yepayipi elihlanganisiwe, ipayipi elingenamthungo lihlanganiswe nomehluko omkhulu kakhulu. I-Longitudinal ngemuva kokushiswa kwe-high-frequency welding, i-seam seam set carbon ayikwazi ukuqedwa, i-weld futhi umzali avele ahlangane futhi angahlanganiswa ngokuphelele abe munye - akakwazanga ukumelana nesikhathi nokucindezela. Ukushisa okushisayo kunciphisa ipayipi lensimbi yokushisela imvamisa ephezulu ngemuva kokushisisa ukuze kudlule lonke, izinga lokushisa eliphelele le-annealing lama-degree angama-800, bese livula inqubo yokushintsha, ngemuva kwalokho uchungechunge lwezinqubo, ukusebenza kwe-weld kanye nokusebenza kwenhlangano yomzali - kube okufanayo ekuncibilikeni okuphelele, okwenziwe kahle ukusuka kumthungo kuya kuguquko olungenamthungo.
