Umbhobho odityanisiweyoyahlulahlulwe ngokubanzi kumbhobho odityanisiweyo othe tye kunye nombhobho odityanisiweyo weentlobo ezimbini.

Inkqubo yokuwelda

Ukusuka kwinkqubo yokuwelda, indlela yokuwelda yombhobho odityanisiweyo kunye nombhobho wentsimbi womthungo othe tye uyahambelana, kodwa umbhobho odityanisiweyo othe tye uya kuba ne-weld eninzi enemilo ye-t, ngoko ke amathuba okuba iziphene ziphuculwe kakhulu. I-t-shaped seam welding residual stress inkulu, imeko yoxinzelelo lwentsimbi ye-weld ihlala ngeendlela ezintathu kwandisa amathuba okuqhekeka.Kwaye, ngokwemigaqo yenkqubo ye-arc welding ephantsi kwamanzi, i-weld nganye iya kuba ne-arc kunye ne-arc. in, kodwa yonke imibhobho edityanisiweyo ethe tye xa i-weld girth, ayikwazi ukuhlangabezana neemeko, ngaloo ndlela kusenokubakho iziphene kwi-arc welding.

Iimpawu zamandla

Xa uxinzelelo kumbhobho ukumelana, ngokuqhelekileyo uxinzelelo ezimbini eziphambili eludongeni, ukuba uxinezeleko radial kunye axialδ.Uxinzelelo lweweld yokwenziwaδ, aphoα yi-engile ye-helix ye-spiral weld pipe.I-Spiral welded seam degree ye-helix angle iqhelekile ukuba yenziwe, kwaye i-spiral weld Uxinzelelo lwe-Longitudinal lolona xinzelelo luphambili.Ngaphantsi koxinzelelo olufanayo lokusebenza, umbhobho ojikelezayo wobubanzi obufanayo kunodonga lwe-Longitudinal ubukhulu bunokuncipha.

Amandla okuqhuma kweHydrostatic

Ngovavanyo olufanelekileyo lothelekiso lokuqinisekisa umbhobho we-spiral welded kunye noxinzelelo lwesivuno seLongitudinal kunye noxinzelelo olugqabhukileyo olulinganisiweyo kunye nexabiso lethiyori..umdlalo, ukutenxa kusondele.Kodwa nokuba luxinzelelo lwesivuno okanye uxinzelelo olugqabhukileyo, bezisezantsi kuneLongitudinal spiral welded.Uvavanyo lwe-Burst lukwabonisa ukuba ireyithi ye-deformation ring spiral welded umbhobho ogqabhukileyo i-Longitudinal inkulu kunomlomo.Ngaloo ndlela kuqinisekiswa ukuba i-spiral welded deformation ye-plastiki isakhono kune-Longitudinal, umlomo oqhumayo uvalelwa ngokubanzi kwi-pitch, ekwandiswa kwe-spiral weld ukukrazula kwisiphumo esibophelelayo esinamandla.

Ukuqina kunye namandla okudinwa

Umkhwa wokuphuhliswa kombhobho unobubanzi obukhulu kunye namandla aphezulu.Ngokunyuka kobubanzi bombhobho kunye nokwenyuka kwebakala lentsimbi, ingcebiso enkulu ye-ductile fracture iyanda ukwanda.Nangona umbhobho odityanisiweyo ojikelezayo kunye nombhobho odityanisiweyo othe ngqo unomgangatho ofanayo, umbhobho odityanisiweyo we-spiral unokuqina kwempembelelo ephezulu.Imibhobho yokuhambisa ngenxa yobungakanani botshintsho kumsebenzi wangempela, umbhobho uxhomekeke kwisiphumo somthwalo oguqukayo.
