Omaka bomkhiqizo

Ishubhu lensimbi elingunxande eliphehliwe yigama lepayipi eliyisikwele nepayipi elingunxande, okuyipayipi elinobude obufanayo obuseceleni.Yenziwe nge-strip steel ngemuva kokucubungula nokugingqa.Ngokuvamile, umucu uyapakishwa, ulinganiswe, uboshwe bese ushiselwa ube yishubhu eliyindilinga, eligoqwe libe ishubhu lesikwele bese lisikwa libe ngobude obudingekayo.Ngokuvamile izinti ezingama-50 iphakethe ngalinye.Kwaziwa nangokuthi amakhaza ayisikwele nonxande akha insimbi engenalutho, ebizwa ngokuthi ipayipi eliyisikwele nepayipi elingunxande, ikhodi F no-J ngokulandelanayo.

Ishubhu Yensimbi Eyisikwele Eyisikwele Egandayiwe Iphepha

1.Ithubhu lensimbi elingunxande elinamagqabhagqabha, Ukuchezuka okuvumelekile kokujiya kodonga akumele kweqe ugqinsi oluphozithivu noma olunegethivu u-10% wokuqina kodonga lapho ukushuba kodonga kungaphansi kuka-10mm, kanye no-8% omuhle noma ongemuhle wodonga lokuzisholo uma udonga ukujiya kungaphezu kuka-10mm, ngaphandle kokuqina kodonga lwekhona nendawo yokushisela.

2.Ithubhu lensimbi elingunxande elinamagalazi, Ubude obujwayelekile bokulethwa bungu-4000mm-12000mm, obungu-6000mm no-12000mm ngobuningi.Ishubhu elingunxande eliyisikwele livumela ukulethwa kwemikhiqizo engekho ngaphansi kuka-2000mm emifushane nengajwayelekile, futhi ingalethwa ngendlela yeshubhu lesixhumi esibonakalayo, kodwa ikhasimende kufanele lisuse ishubhu yesixhumi esibonakalayo lapho lisebenzisa.Isisindo semikhiqizo yobude obufushane noma obungajwayelekile akumele seqe u-5% yenani eliphelele lokulethwa, futhi kumashubhu angama-rectangular ayisikwele anesisindo sethiyori esikhulu kuno-20kg/m akumele seqe u-10% yenani eliphelele lokulethwa.

3.Ishubhu lensimbi elingunxande elinamagalanisi, Idigri yokugoba akumele ibe nkulu kuno-2mm imitha, futhi ingqikithi yokugoba idigri ngeke ibe nkulu kuno-0.2% wabo bonke ubude.

Ukwehlukaniswa Kwethubhu Yensimbi Eyisikwele Esiyisikwele Esiqinile Kwethulwa

1, ukuhlukaniswa kwenqubo yokukhiqiza ishubhu yesikwele
Ishubhu yesikwele ngokuya ngenqubo yokukhiqiza: ishubhu lesikwele elishisayo eligoqiwe elingenamthungo, ishubhu lesikwele elidonswayo elibandayo, cindezela ishubhu lesikwele elingenamthungo, ishubhu lesikwele elishiselwe.Amashubhu ashiselwe isikwele ahlukaniswe: (a) ngenqubo -- amashubhu ayisikwele welding arc, amashubhu ayisikwele welding (imvamisa ephezulu, imvamisa ephansi), amashubhu ayisikwele ashisela igesi, amashubhu ayisikwele ashisela esithandweni (b) ngomugqa wokushisela -- oqondile umthungo Welding amashubhu square, Kuvunguza welding square amashubhu

2. Ukuhlukaniswa kwempahla yeshubhu elingunxande
Ishubhu yesikwele ngokuya ngezinto ezibonakalayo: plain carbon steel square tube, low alloy square tube.General carbon steel ihlukaniswe: Q195, Q215, Q235, SS400, 20 # steel, 45 # steel;Insimbi ye-alloy ephansi ihlukaniswe nge-Q345, 16Mn, Q390, ST52-3, njll.

3. Ukuhlukaniswa okujwayelekile kokukhiqizwa kwepayipi elingunxande
Ishubhu yesikwele ngokwezindinganiso zokukhiqiza: ishubhu yesikwele ye-gb, ishubhu yesikwele esijwayelekile saseJapan, ishubhu yesikwele yesistimu yaseBrithani, ishubhu yesikwele esijwayelekile saseMelika, ishubhu yesikwele esijwayelekile saseYurophu, ishubhu yesikwele esingajwayelekile.

4, ukuhlukaniswa komumo wesigaba seshubhu elingunxande
Ishubhu eliyisikwele lihlukaniswa ngokuma kwesigaba: (1) ishubhu eliyisikwele lesigaba esilula -- ishubhu lesikwele, ishubhu elingunxande (2) ingxenye eyinkimbinkimbi yeshubhu yesikwele -- umumo wezimbali ishubhu lesikwele, ishubhu lesikwele elimise okumile, ishubhu lesikwele eliwuthayela, ishubhu lesikwele elimise okukhethekile.

5, isikwele tube indawo ukwelashwa ngezigaba
Ishubhu yesikwele ngokusho kokwelashwa okungaphezulu: ishubhu lesikwele elishisayo, ishubhu yesikwele eyisikwele kagesi, ishubhu lesikwele eligcotshwe ngamafutha, ishubhu yesikwele yokukhetha

6, ukuhlukaniswa kwe-square tube ukusetshenziswa
Amashubhu ayisikwele ahlukaniswa ngokuya ngokusetshenziswa kwawo -- amashubhu ayisikwele okuhlobisa, amashubhu ayisikwele amathuluzi omshini, amashubhu ayisikwele emboni yemishini, amashubhu ayisikwele emboni yamakhemikhali, amashubhu ayisikwele ezakhiwo zensimbi, amashubhu ayisikwele okwakha umkhumbi, amashubhu ayisikwele ezimoto, isikwele amashubhu emishayo yensimbi namakholomu, amashubhu ayisikwele ngezinjongo ezikhethekile

7. Ukuhlukaniswa kokuqina kwezindonga zepayipi elingunxande
Amashubhu angunxande ayisikwele ahlukaniswa ngokokuqina kodonga -- amashubhu ayisikwele angunxande anezindonga eziwugqinsi, amashubhu angunxande anezindonga eziyisikwele kanye namashubhu ayisikwele anezindonga ezincanyana angunxande.
