Ipayipi lesikwele igama lepayipi eliyisikwele kanye nepayipi elingunxande, okungukuthi, ipayipi lensimbi elinobude obulinganayo futhi obungalingani. Yenziwe ngensimbi egoqiwe ngemuva kokwelashwa kwenqubo. Ngokuvamile, insimbi ye-strip iyakhishwa, ilinganiswe, igwetshwe futhi ishiselwe ukuze yakhe ipayipi eliyindilinga, bese igoqwa ibe yipayipi eliyisikwele elisuka epayipini eliyindilinga, bese lisikwa libe ngobude obudingekayo.

1. Ukuchezuka okuvumelekile kokuqina kodonga lwepayipi eliyisikwele akumele kudlule ukuhlanganisa noma kususe u-10% wogqinsi oluvamile lodonga lapho ukujiya kodonga lungengaphezu kuka-10mm, kanye noma kukhishwe u-8% wobukhulu bodonga lapho ukujiya kodonga kungaphezulu. kuno-10mm, ngaphandle kokuqina kodonga lwamakhona nezindawo zokushisela.

2. Ubude obujwayelekile bokulethwa kwepayipi lesikwele elingunxande ngu-4000mm-12000mm, ikakhulukazi u-6000mm no-12000mm. Ishubhu elingunxande livunyelwe ukuletha imikhiqizo yobude obufushane nengagxilile engekho ngaphansi kuka-2000mm, futhi ingalethwa nangeshubhu yesixhumi esibonakalayo, kodwa i-Demander izosika ishubhu yesixhumi esibonakalayo lapho ilisebenzisa. Isisindo segeji elifushane kanye nemikhiqizo yegeji engaguquki akumele seqe u-5% wevolumu yokulethwa okuphelele. Kumashubhu esikhashana esikwele anesisindo sethiyori esikhulu kuno-20kg/m, akumele kudlule u-10% wevolumu ephelele yokulethwa.

3. Idigri yokugoba yepayipi elingunxande eliyisikwele akufanele libe likhulu kuno-2mm imitha, futhi ingqikithi yokugoba idigri akufanele ibe nkulu kuno-0.2% wabo bonke ubude.

Ngokwenqubo yokukhiqiza, amashubhu ayisikwele ahlukaniswe abe amashubhu ayisikwele agingqiwe ashisayo angenamthungo, amashubhu ayisikwele adonswa abandayo angenamthungo, amashubhu ayisikwele akhishiwe angenamthungo kanye namashubhu ayisikwele ashiselwe.

Ipayipi eliyisikwele elishiselwe lihlukaniswe libe

1. Ngokwenqubo - i-arc welding square tube, ukumelana ne-welding square tube (imvamisa ephezulu kanye nemvamisa ephansi), i-gas welding square tube kanye nesithando somlilo welding square tube

2. Ngokusho kwe-weld - ipayipi eliyisikwele elihlanganisiwe eliqondile kanye nepayipi eliyisikwele elihlanganisiwe.

Ukuhlukaniswa kwezinto

Amashubhu ayisikwele ahlukaniswe abe amashubhu ayisikwele e-carbon steel ajwayelekile kanye namashubhu ayisikwele angama-alloy aphansi ngokuya ngezinto ezibonakalayo.

1. Insimbi ye-carbon evamile ihlukaniswe nge-Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, njll.

2. Insimbi ye-alloy ephansi ihlukaniswe nge-Q345, 16Mn, Q390, St52-3, njll.

Ukuhlukaniswa okujwayelekile kokukhiqiza

Ishubhu yesikwele ihlukaniswe yaba yithubhu yesikwele esezingeni likazwelonke, ishubhu yesikwele esijwayelekile saseJapan, ishubhu yesikwele esijwayelekile saseBrithani, ishubhu yesikwele esijwayelekile saseMelika, ishubhu yesikwele esijwayelekile saseYurophu kanye neshubhu lesikwele esingajwayelekile ngokwezindinganiso zokukhiqiza.

Ukuhlukaniswa komumo wesigaba

Amapayipi ayisikwele ahlukaniswa ngokuya ngomumo wesigaba:

1. I-tube yesikwele yesigaba esilula: ithubhu yesikwele, ishubhu elingunxande.

2. Ishubhu yesikwele enesigaba esiyinkimbinkimbi: ishubhu yesikwele emise okwembali, ishubhu lesikwele esivulekile, ishubhu lesikwele eliwuthayela kanye neshubhu lesikwele elimise okukhethekile.

Ukuhlukaniswa kokwelashwa kwendawo

Amapayipi angama-square ahlukaniswe amapayipi ayisikwele ashisayo-diphu, amapayipi ayisikwele angama-electro galvanized, amapayipi ayisikwele agcotshwe amafutha kanye namapayipi wesikwele afakwe emanzini anosawoti ngokusho kokwelashwa kwendawo.

Sebenzisa ukuhlukanisa

Amashubhu ayisikwele ahlukaniswa ngokusetshenziswa: amashubhu ayisikwele okuhlobisa, amashubhu ayisikwele emishini yamathuluzi omshini, amashubhu ayisikwele emboni yemishini, amashubhu ayisikwele emboni yamakhemikhali, amashubhu ayisikwele esakhiwo sensimbi, amashubhu ayisikwele okwakha umkhumbi, amashubhu ayisikwele emoto, amashubhu ayizikwele imishayo yensimbi namakholomu, namashubhu ayisikwele ngezinjongo ezikhethekile.

Ukuhlukaniswa kokuqina kwezindonga

Amashubhu angunxande ahlukaniswa ngokokuqina kodonga: amashubhu awunxande anodonga aminyene, amashubhu awunxande anodonga oluqinile namashubhu angama-rectangular anezindonga ezincane. Ifektri yethu inobuchwepheshe bokukhiqiza emakethe, futhi inekhono kakhulu. Siyakwamukela abangani bamazwe ngamazwe ozobonisana nabo. Sizozama konke okusemandleni ethu ukuhlangabezana nezidingo zakho ezihlukahlukene.
