Umthumeli ngaphandle kwe-Intanethi iTianjin Youfa Brand Spiral Welded Steel Pipe

Spiral Welded Steel Pipes Manufacturing Process

Ukukhethwa kwezinto:

Iintsimbi zetsimbi: Iikhoyili zetsimbi ezikumgangatho ophezulu zikhethwa, ngokuqhelekileyo zenziwe kwi-low-carbon or medium-carbon steel, ukuhlangabezana neempawu ezifunekayo zomatshini kunye nokwakheka kweekhemikhali.

Ukuqhawula kunye nokuCandwa:

Ukuqhawula: Iikhoyili zentsimbi azikhohliwe kwaye zicandwe kwifom yephepha.
UkuSlitting: Intsimbi eyisicaba inqunyulwa ibe yimicu yobubanzi obufunekayo. Ububanzi bomgca bumisela ububanzi bombhobho wokugqibela.

Ukubumba:

I-Spiral Formation: Umcu wentsimbi utyiswa ngothotho lweerola ezithi ngokuthe ngcembe ziwenze ube yimo engqukuva. Imiphetho yomtya idityaniswe kunye kwipatheni ye-helical ukwenza umbhobho.

Ukuwelda:

I-Summerged Arc Welding (SAW): I-spiral seam yombhobho idityaniswe ngokusebenzisa inkqubo ye-arc welding ephantsi kwamanzi. Oku kubandakanya ukusetyenziswa kwe-arc yombane kunye ne-granular flux, enika i-weld eqinile, esemgangathweni ophezulu kunye ne-spatter encinci.
Ukuhlolwa kwe-Weld Seam: Umthungo we-weld uhlolwe umgangatho usebenzisa iindlela zokuvavanya ezingonakalisi ezifana novavanyo lwe-ultrasonic okanye lwe-radiographic.

Ubungakanani kunye nokuBumba:

IiSizing Mills: Umbhobho odityanisiweyo udlula kwimilinganiselo yokusila ukufikelela kwidayamitha echanekileyo kunye nobungqukuva obufunekayo.
Ukwandiswa: Ukwandiswa kwe-hydraulic okanye koomatshini kungasetyenziselwa ukuqinisekisa imilinganiselo yemibhobho efanayo kunye nokuphucula iimpawu zemathiriyeli.

Uvavanyo olungangonakalisi:

Uvavanyo lwe-Ultrasonic (UT): Isetyenziselwa ukufumanisa iziphene zangaphakathi kwi-weld seam.
Uvavanyo lwe-Hydrostatic: Umbhobho ngamnye uphantsi kovavanyo loxinzelelo lwe-hydrostatic ukuqinisekisa ukuba inokusingatha uxinzelelo lokusebenza ngaphandle kokuvuza.

Ukugqibezela:

I-Beveling: Iziphelo zemibhobho zifakwe kwi-beveled ukulungiselela i-welding kwindawo yofakelo.
Unyango loMphezulu: Imibhobho inokufumana unyango olungaphezulu olunjengokucoca, ukugquma, okanye ukugalela intsimbi ukomeleza ukuxhathisa ukudleka.

Uhlolo noLawulo loMgangatho:

Ukuhlolwa koMda: Imibhobho ihlolwe ukuthotyelwa kwedayamitha, ubukhulu bodonga, kunye neenkcukacha zobude.
Uvavanyo loomatshini: Imibhobho ivavanyelwa ukomelela kokuqina, ukomelela kwesivuno, ubude, kunye nokuqina ukuqinisekisa ukuba iyahlangabezana nemigangatho efunekayo.

UkuMakisha nokuPakisha:

Ukumakisha: Imibhobho iphawulwe ngolwazi olubalulekileyo olufana negama lomenzi, iinkcukacha zemibhobho, ibakala, ubungakanani, kunye nenani lobushushu ukwenzela ukulandeleka.
Ukupakishwa: Imibhobho iyadityaniswa kwaye ipakishwe ngokweemfuno zabathengi, ilungele ukuthuthwa kunye nokufakwa.
