Ishubhu yesikwele esiphekiwe kanye neshubhu elingunxande

Incazelo emfushane:

Ipayipi elingunxande eliphehliwe yigama lepayipi eliyisikwele kanye nepayipi elingunxande, okungukuthi, amapayipi ensimbi anobude obulinganayo obuseceleni. Yenziwa ngokugoqa umugqa wensimbi ngemuva kokwelashwa kwenqubo. Ngokuvamile, insimbi ye-strip iyapakishwa, ibekwe isicaba, iboshwe bese ishiselwa ukuze yakhe ishubhu eliyindilinga, bese ishubhu eliyindilinga ligoqwe 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 eliyisikwele neshubhu elingunxande, amakhodi athi F kanye no-J ngokulandelanayo.

Imininingwane Yomkhiqizo

Omaka bomkhiqizo

1. Ukuchezuka okuvumelekile kokuqina kodonga lweshubhu elingunxande eliyisithako akumele kudlule kuhlanganiswe noma kukhishwe u-10% wogqinsi oluvamile lodonga lapho ukujiya kodonga kungaphansi kuka-10mm, futhi lapho ukujiya kodonga kungaphezu kuka-10mm, kuhlanganisa noma kususe u-8% wogqinsi lodonga. 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 ingalethwa ngendlela yamapayipi okuxhumana, kodwa umthengi kufanele anqume ipayipi yesixhumi esibonakalayo lapho esisebenzisa. Isisindo semikhiqizo yobude obufushane kanye nobude obungaguquki akufanele sidlule u-5% wevolumu yokulethwa okuphelele, futhi kumashubhu angama-rectangular square anesisindo sethiyori esingaphezu kuka-20kg/m, akufanele sidlule u-10% wevolumu yokulethwa okuphelele.

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

Isingeniso Sezigaba

1. Ukuhlukaniswa kwenqubo yokukhiqiza yeshubhu elingunxande
Amashubhu angunxande ahlukaniswa ngokwenqubo yokukhiqiza: amashubhu ayisikwele agingqiwe ashisayo angenamthungo, amashubhu ayisikwele adonswa ngokubanda angenamthungo, amashubhu ayisikwele akhishiwe angenamthungo, namashubhu ayisikwele ashiselwe. Phakathi kwazo, ipayipi yesikwele esihlanganisiwe ihlukaniswe: (a) Ngokusho kwepayipi le-arc welding square, ukumelana nepayipi le-welding square (imvamisa ephezulu, imvamisa ephansi), ipayipi legesi le-welding square, ipayipi le-welding yesithando somlilo (b) ngokusho kwe-weld-straight Seam eshiselwe ipayipi yesikwele, ipayipi yesikwele esivunguzayo.

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 ayisikwele ayinkimbinkimbi amise okwezimbali, amapayipi ayizikwele amise okwezimbali, amapayipi ayisikwele anothayela, amapayipi ayisikwele anomumo okhethekile.

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 embonini yemishini, amapayipi ayisikwele emboni yamakhemikhali, amapayipi ayisikwele ezakhiwo zensimbi, amapayipi ayisikwele okwakhiwa kwemikhumbi, amapayipi ayisikwele ezimoto, amapayipi ayisikwele emishayo yensimbi namakholomu Ishubhu, ishubhu lesikwele lenhloso ekhethekile.

7. Ukuhlukaniswa kwe-rectangular tube wall ukujiya
Amapayipi angama-rectangular ahlukaniswa ngamapayipi angama-rectangular anezindonga eziwugqinsi kakhulu, 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 neyamakhemikhali, izindonga zamakhethini engilazi, i-chassis yezimoto, izikhumulo zezindiza, njll.
