Ishubhu yesikwele esiphekiwe kanye neshubhu elingunxande

Galvanized square tube & rectangular tube Featured Image

Incazelo emfushane:

Ipayipi elingunxande eliphehliwe yigama lepayipi eliyisikwele kanye nepayipi elingunxande, okungukuthi, amapayipi ensimbi anobude obulinganayo obuhlangothini.Yenziwa ngokugoqa umugqa wensimbi ngemuva kokwelashwa kwenqubo.Ngokuvamile, insimbi ye-strip iyapakishwa, ifakwe isicaba, iboshwe, bese ishiselwa ukuze yakhe ishubhu eliyindilinga, bese ishubhu eliyindilinga ligoqwa libe yishubhu lesikwele bese lisikwa libe ubude obudingekayo.Ngokuvamile izingcezu ezingu-50 iphakethe ngalinye.Eyaziwa nangokuthi isikwele kanye nensimbi yesigaba esibandayo esakhiwe ngendlela ebandayo, esifushanisiwe njengeshubhu lesikwele neshubhu elingunxande, amakhodi athi F kanye no-J ngokulandelanayo.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

1. Ukuchezuka okuvunyelwe kogqinsi lodonga lweshubhu elingunxande elivunyiwe akumele kudlule ukuhlanganisa noma kususe u-10% wogqinsi oluvamile lodonga lapho ukujiya kodonga kungaphansi kuka-10mm, futhi lapho ukujiya kodonga kungaphezu kuka-10mm, kuhlanganisa noma khipha u-8% wobukhulu bodonga.Ngaphandle kokuqina kodonga endaweni yomthungo.

2. Ubude obujwayelekile bokulethwa kweshubhu elingunxande eliphekiwe ngu-4000mm-12000mm, ikakhulukazi u-6000mm no-12000mm.Amapayipi angama-Rectangular avunyelwe ukuletha imikhiqizo yobude obufushane kanye ne-non-fixed-ubude obungekho ngaphansi kuka-2000mm, futhi ingathunyelwa ngendlela yamapayipi okuxhumana, kodwa umthengi kufanele anqume ipayipi yesixhumi esibonakalayo lapho esisebenzisa.Isisindo semikhiqizo yobude obufushane kanye nobude obungaguquki akumele seqe u-5% wevolumu ephelele yokulethwa, futhi kumashubhu angama-rectangular ayisikwele anesisindo sethiyori esingaphezu kuka-20kg/m, akumele seqe u-10% wevolumu ephelele yokulethwa. .

3. Ukugoba kweshubhu elingunxande eliyisithako akufanele kube kukhulu kuno-2mm imitha, futhi ukugoba okuphelele akufanele kube kukhulu kuno-0.2% wabo bonke ubude.

Isingeniso Sezigaba

1. Ukuhlukaniswa kwenqubo yokukhiqiza yeshubhu elingunxande
Amashubhu angunxande ahlukaniswa ngokwenqubo yokukhiqiza: amashubhu ayisikwele agingqiwe ashisayo angenamthungo, amashubhu ayisikwele adonswa ukubanda angenamthungo, amashubhu ayisikwele akhishiwe angenamthungo, namashubhu ayisikwele ashiselwe.Phakathi kwazo, ipayipi yesikwele esihlanganisiwe ihlukaniswe: (a) Ngokwenqubo-i-arc welding square pipe, ukumelana nepayipi yesikwele (imvamisa ephezulu, imvamisa ephansi), i-gas welding square pipe, isithando somlilo welding square (b) ngokusho i-weld-straight Seam eshiselwe ipayipi eliyisikwele, ipayipi eliyisikwele elisontekile

2. Ukuhlukaniswa kwempahla yeshubhu elingunxande
Amapayipi wesikwele ahlukaniswa ngokwezinto zawo: amapayipi ayisikwele e-carbon steel kanye namapayipi angama-square angama-alloy aphansi.I-carbon steel evamile ihlukaniswe: Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, njll.;insimbi ephansi ye-alloy ihlukaniswe yaba yi-Q345, 16Mn, Q390, ST52-3, njll.

3. Ukuhlukaniswa okujwayelekile kokukhiqizwa kweshubhu elingunxande
Amapayipi ayisikwele ahlukaniswa ngokwezindinganiso zokukhiqiza: amapayipi ayisikwele ajwayelekile kazwelonke, amapayipi ayisikwele ajwayelekile aseJapan, amapayipi ayisikwele asebukhosini, amapayipi ayisikwele ajwayelekile aseMelika, amapayipi ayisikwele ajwayelekile aseYurophu, namapayipi angama-square angajwayelekile.

4. Ukuhlukaniswa komumo wesigaba seshubhu elingunxande
Amapayipi ayisikwele ahlukaniswa ngokwezigaba zawo eziphambanayo: (1) amapayipi ayisikwele ayisikwele alula anesiqephu esiyisikwele, amapayipi ayisikwele esingunxande (2) amapayipi ayisikwele ayinkimbinkimbi anesigaba esiphambanayo-amapayipi ayisikwele amise okwezimbali, amapayipi amise okwesikwele amise okwezikwele. , amapayipi ayizikwele zikathayela, amapayipi ayizikwele amise okwesikwele

5. Ukuhlukaniswa kokwelashwa okungaphezulu kweshubhu elingunxande
Amapayipi ayisikwele ahlukaniswe abe yizindlela zokwelapha ezingaphezulu: amapayipi ayisikwele ashisayo-dip, amapayipi angama-electro-galvanized square, amapayipi ayisikwele agcotshwe ngamafutha, amapayipi ayisikwele afakwe emanzini.

6. Sebenzisa ukuhlukaniswa kweshubhu elingunxande
Amapayipi wesikwele ahlukaniswa ngamapayipi ayisikwele okuhlobisa, amapayipi ayisikwele amathuluzi omshini, amapayipi ayisikwele emboni yemishini, amapayipi ayisikwele emboni yamakhemikhali, amapayipi ayisikwele ezakhiwo zensimbi, amapayipi ayisikwele okwakhiwa kwemikhumbi, amapayipi ayisikwele ezimoto, amapayipi ayisikwele ensimbi. imishayo namakholomu Ishubhu, ishubhu yesikwele inhloso ekhethekile

7. Ukuhlukaniswa kwe-rectangular tube wall ukujiya
Amapayipi angama-rectangular ahlukaniswa ngamapayipi angama-rectangular anezindonga eziwugqinsi, amapayipi angama-rectangular anezindonga eziqinile kanye namapayipi angama-rectangular anezindonga ezincane.

Sebenzisa

Isetshenziswa kakhulu ezindongeni zamakhethini, ukwakhiwa, ukukhiqizwa kwemishini, amaphrojekthi wokwakha insimbi, ukwakhiwa kwemikhumbi, abakaki abaphehla amandla elanga, ubunjiniyela besakhiwo sensimbi, ubunjiniyela bamandla, izitshalo zamandla, imishini yezolimo namakhemikhali, izindonga zamakhethini engilazi, i-chassis yemoto, izikhumulo zezindiza, njll.
