1. Inkqubo yoMveliso

Umbhobho wentsimbi engenamthungo

Iipayipi ezingenamthungo zenziwe ngeiibhilethi zentsimbi eqinileyoI-billet iyafudunyezwa ize igqojwe ukuze kwenziwe ityhubhu engenanto. Emva koko ityhubhu iyaqengqeleka okanye itsalwe kwimilinganiselo yokugqibela kusetyenziswaiindlela zokuzoba ezishushu okanye ezibandayo.

Amanyathelo aphambili:

l Ukufudumala kunye nokuhlolwa kwebillet yentsimbi

Ukubhoboza iibhilethi ukuze kwenze iqokobhe elingenanto

l Ukuqengqeleka okushushu okanye ukukhupha

l Umzobo obandayo (onganyanzelekanga kwiityhubhu ezichanekileyo)

l Unyango lobushushu, ukuqondisa, kunye nokugqiba

 

Imibhobho engenamthungo inayoakukho mthungo wokuwelda, enika iipropati ezifanayo zoomatshini kulo lonke ujikelezo.

Umbhobho wentsimbi ewelding

Imibhobho edibeneyo yenziwa ngokuqengqa iipleyiti zentsimbi okanye imicu ibe yimilo ye-cylindrical, emva koko idityaniswa umthungo kusetyenziswaUkuwelda kokumelana nombane (ERW), ukuWelda okude, okanye ukuWelda okujikelezayo.

Amanyathelo aphambili:

l Ipleyiti yentsimbi/ukwakha umcu

l Ukulungiselela umphetho kunye nokuwelda

l Unyango lobushushu okanye ukukhululeka kuxinzelelo (ukhetho)

l Ukulungisa, ubungakanani, kunye nokugqiba

 

Nangona imibhobho edibeneyo ine-seam, iindlela eziphambili ezifanaumzobo obandayo phezu kwe-mandrel (DOM)kunye nokugqitywa ngokuchanekileyo kunciphisa ukubonakala komthungo kwaye kuphucule ukufana kwesakhiwo.

Ipropati	Umbhobho ongenamthungo	Umbhobho odibeneyo	Amanqaku
Unikeze Amandla	Phezulu	Phakathi ukuya phezulu	Imibhobho engenamthungo iphatha uxinzelelo oluphezulu ngenxa yesakhiwo esifanayo
Tensile strength	Phezulu	Iphakathi	Imibhobho engenamthungo inomjelo ofanayo wengqolowa kujikelezo
Ukumelana noxinzelelo	Phezulu kakhulu	Phakathi ukuya phezulu	Iipayipi ezingenamthungo zikhethwa kwiinkqubo zoxinzelelo oluphezulu
Ukuqina	Igqwesile	Kulungile	Umthungo we-weld unganciphisa kancinci ukuqina kwimibhobho e-welded
Ukumelana nokudinwa	Igqwesile	Kulungile	Imibhobho engenamthungo imelana ngcono nomthwalo ojikelezayo

Iipayipi zentsimbi ezingenamthungo ngokubanziyomelele kwaye ihlala ixesha elidekunemibhobho edibeneyo. Imibhobho edibeneyo idla ngokubaengabizi kakhulukwaye isafanelekile kwiintlobo ngeentlobo zezicelo zoshishino nezakhiwo.

 

3. Ukuchaneka kunye nokunyamezelana ngokwemilinganiselo

Iipayipi ezingenamthungo, ingakumbiimibhobho engenamthungo etsalwe ngokubandayo, isiphoukunyamezelana okuqinileyo, ukujiya okuphantsi, kunye nokuthe tye okuphezulu. Oku kubenza bafaneleke kakhuluiinkqubo zoomatshini ezichanekileyo, imibhobho enoxinzelelo oluphezulu, kunye neetyhubhu zebhoyila.

Ipharamitha	Umbhobho ongenamthungo	Umbhobho odibeneyo	Amanqaku
Ukunyamezelana kobubanzi bangaphandle	± 0.05–0.10 mm	± 0.1–0.25 mm	Iipayipi ezingenamthungo zichaneke kakhulu
Ukuqanda	≤50% yokunyamezelana kwe-OD	≤75% yokunyamezelana kwe-OD	Umthungo we-Weld unokuchaphazela ukungqukuva
Ukuthe tye	≤1/1000	≤2/1000	Imibhobho engenamthungo inokutsalwa ukuze iqonde ngokuchanekileyo
Ubukhulu bodonga	± 7.5%	± 10%	Iipayipi ezingenamthungo zibonelela ngobukhulu bodonga obufanayo
