Ipayipi eliyisikwele liyigama lepayipi eliyisikwele kanye nepayipi elingunxande, okungukuthi, ipayipi lensimbi elinobude obulinganayo nobungalingani ohlangothini. Lenziwe ngensimbi egoqiwe ngemva kokwelashwa kwenqubo. Ngokuvamile, insimbi eyisikwele iyasuswa, ilinganiswe, igoqwe futhi ihlanganiswe ukuze kwakhiwe ipayipi eliyindilinga, bese igoqwa ibe yipayipi eliyisikwele kusukela epayipini eliyindilinga, bese inqunywa ibe ubude obudingekayo.

1. Ukuphambuka okuvumelekile kobukhulu bodonga lwepayipi eliyisikwele akufanele kudlule u-plus noma u-minus ongu-10% wobukhulu bodonga obujwayelekile lapho ubukhulu bodonga bungekho ngaphezu kuka-10mm, kanye noma u-minus ongu-8% wobukhulu bodonga lapho ubukhulu bodonga bungaphezu kuka-10mm, ngaphandle kobukhulu bodonga lwamakhona nezindawo zokushisela.

2. Ubude obujwayelekile bokulethwa kwepayipi eliyisikwele elingunxande bungu-4000mm-12000mm, ikakhulukazi u-6000mm no-12000mm. Ipayipi eliyisikwele livunyelwe ukuletha imikhiqizo yobude obufushane nobungaguquki okungenani u-2000mm, futhi lingathunyelwa ngesimo sepayipi eliyisikwele, kodwa i-Demander izosika ipayipi eliyisikwele uma iyisebenzisa. Isisindo semikhiqizo yegeyiji emfushane negeyiji engaguquki akufanele sidlule u-5% wevolumu yokulethwa iyonke. Kumapayipi e-square moment anesisindo esingaphezu kuka-20kg / m, akufanele sidlule u-10% wevolumu yokulethwa iyonke.

3. Izinga lokugoba lepayipi elingunxande eliyisikwele akumele libe ngaphezu kuka-2mm ngemitha, futhi izinga lokugoba eliphelele akumele libe ngaphezu kuka-0.2% wobude obuphelele

Ngokwenqubo yokukhiqiza, amashubhu asikwele ahlukaniswe ngamashubhu asikwele angenamthungo ashiswayo, amashubhu asikwele angenamthungo adonswayo abandayo, amashubhu asikwele angenamthungo akhishwe kanye namashubhu asikwele ahlanganisiwe.

Ipayipi lesikwele elihlanganisiwe lihlukaniswe phakathi

1. Ngokwenqubo – ishubhu lesikwele lokushisela i-arc, ishubhu lesikwele lokushisela ukumelana (imvamisa ephezulu kanye nemvamisa ephansi), ishubhu lesikwele lokushisela igesi kanye neshubhu lesikwele lokushisela isithando somlilo

2. Ngokusho kwe-weld - ipayipi lesikwele elihlanganisiwe eliqondile kanye nepayipi lesikwele elihlanganisiwe elijikelezayo.

Ukuhlukaniswa kwezinto

Amashubhu ayisikwele ahlukaniswe ngamashubhu ajwayelekile ensimbi yekhabhoni kanye namashubhu ayisikwele aphansi ngokwezinto ezibonakalayo.

1. Insimbi yekhabhoni evamile ihlukaniswe phakathi kwe-Q195, Q215, Q235, SS400, 20# insimbi, 45# insimbi, njll.

2. Insimbi e-alloy ephansi ihlukaniswe phakathi kwe-Q345, 16Mn, Q390, St52-3, njll.

Ukuhlukaniswa okujwayelekile kokukhiqiza

Ishubhu lesikwele lihlukaniswe ngeshubhu lesikwele elijwayelekile likazwelonke, ishubhu lesikwele elijwayelekile laseJapan, ishubhu lesikwele elijwayelekile laseBrithani, ishubhu lesikwele elijwayelekile laseMelika, ishubhu lesikwele elijwayelekile laseYurophu kanye neshubhu lesikwele elingeyona ejwayelekile ngokwezindinganiso zokukhiqiza.

Ukuhlukaniswa kwesimo sesigaba

Amapayipi ayisikwele ahlukaniswa ngokwesimo sesigaba:

1. Ishubhu lesikwele eliyisigaba esilula: ishubhu lesikwele, ishubhu elingunxande.

2. Ishubhu eliyisikwele elinesigaba esiyinkimbinkimbi: ishubhu eliyisikwele elimise okwembali, ishubhu eliyisikwele elivulekile, ishubhu eliyisikwele eligoqekile kanye neshubhu eliyisikwele elimise okwekhethelo.

Ukuhlukaniswa kokwelashwa kwendawo

Amapayipi ayisikwele ahlukaniswe ngamapayipi ayisikwele afakwe igesi ashisayo, amapayipi ayisikwele afakwe igesi kagesi, amapayipi ayisikwele afakwe amafutha kanye namapayipi ayisikwele afakwe igesi ngokuya ngokwelashwa kwendawo.

Sebenzisa ukuhlukaniswa

Amashubhu ayisikwele ahlukaniswa ngokusetshenziswa kwawo: amashubhu ayisikwele okuhlobisa, amashubhu ayisikwele emishini yamathuluzi omshini, amashubhu ayisikwele embonini yemishini, amashubhu ayisikwele embonini yamakhemikhali, amashubhu ayisikwele esakhiwo sensimbi, amashubhu ayisikwele okwakha imikhumbi, amashubhu ayisikwele ezimoto, amashubhu ayisikwele emishayo yensimbi namakholomu, kanye namashubhu ayisikwele ezinhloso ezikhethekile.

Ukuhlukaniswa kobukhulu bodonga

Amashubhu angunxande ahlukaniswa ngokobukhulu bodonga: amashubhu angunxande anodonga oluqinile kakhulu, amashubhu angunxande anodonga oluqinile kanye namashubhu angunxande anodonga oluncane. Ifektri yethu inobuchwepheshe bokukhiqiza emakethe, futhi inekhono elikhulu. Siyakwamukela bangani bamazwe ngamazwe ukuthi bazokubonisana. Sizozama konke okusemandleni ethu ukuhlangabezana nezidingo zakho ezahlukahlukene.
