Umkhiqizi wamapayipi ayisikwele anezindonga eziwugqinsi
Njengoba igama liphakamisa, ipayipi eliyisikwele liwuhlobo lwepayipi eliyisikwele. Izinto eziningi zingakha umzimba wepayipi wesikwele. Isetshenziselwa yiphi injongo futhi kuphi. Amapayipi amaningi ayisikwele amapayipi ensimbi. Ngemva kokukhipha, ukukala, ukugoqa kanye nokushisela, bakha amapayipi ayindilinga, asongwe abe amapayipi ayisikwele, abese esikwa abe ubude obudingekayo. Ngokuvamile, kunamashubhu skwele angama-50 iphakheji ngalinye. Ngokuya ngebala, amashubhu amaningi ayisikwele anezincazelo ezinkulu, kusukela ku-10 * 10 * 0.8-1.5 kuya ku-500 * 500 * 10-25. Amashubhu ayisikwele asetshenziselwa amashubhu ayisikwele esakhiwo, amashubhu ayisikwele okuhlobisa, amashubhu okwakha isikwele, amashubhu ayisikwele ayimishini, njll.
Ipayipi eliyisikwele elinezindonga eziwugqinsi luhlobo lwepayipi lensimbi eliwugqinsi eliwugqinsi elinengxenye yesikwele engenalutho, eyaziwa nangokuthi iphrofayili yensimbi eyakhiwe ngokubanda. Kuyinsimbi yesigaba enomumo nosayizi wesigaba sesikwele, esenziwe ngomugqa ogoqekayo we-Q235 ogoqekayo noma ogoqelwe ngokubanda noma ikhoyili njengesisekelo, ukugoba okubandayo kanye ne-high-frequency welding. Ngaphezu kokuqina kodonga, ubukhulu bekhona kanye nokuqina konqenqema kwepayipi eliyisikwele eligoqiwe elishisayo lifinyelela noma lidlule izinga lokumelana nokushisela ipayipi eliyisikwele elibandayo.
Amashubhu ayisikwele anezindonga eziwugqinsi asetshenziswa ekwakheni, ukukhiqizwa kwemishini, amaphrojekthi wokwakha insimbi nensimbi, ukwakhiwa kwemikhumbi, izisekelo zokuphehla amandla elanga, ubunjiniyela besakhiwo sensimbi, ubunjiniyela bamandla, izitshalo zikagesi, imishini yezolimo neyamakhemikhali, izindonga zamakhethini engilazi, i-chassis yemoto, izikhumulo zezindiza, ibhayela. ukwakhiwa, izinsimbi zomgwaqo omkhulu, ukwakhiwa kwezindlu, okufana namashubhu ayisikwele, njll.
Ukuhlukaniswa kwenqubo yokukhiqiza ipayipi eliyisikwele elinezindonga eziwugqinsi
Ngokwenqubo yokukhiqiza, ipayipi eliyisikwele eliwugqinsi lihlukaniswe libe yipayipi eliyisikwele elishisayo eligoqiwe eligoqiwe, ipayipi eliyisikwele elidonswa ngamakhaza, ipayipi eliyisikwele elikhishwe odongeni kanye nepayipi eliyisikwele elishisiwe.
(a) 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.
(b) Ihlukaniswe nge-weld - ipayipi eliyisikwele elishiselwe ngqo kanye nepayipi eliyisikwele elishiselwe okugobile.
Amashubhu ayisikwele ahlukaniswe abe amashubhu ayisikwele e-carbon steel ajwayelekile kanye namashubhu ayisikwele angama-alloy aphansi ngokuya ngezinto ezibonakalayo. Okuvamile carbon steel ihlukaniswe: Q195, Q215, Q235, SS400, 20 # steel, 45 # steel, njll; Izinsimbi eziphansi ze-alloy zihlukaniswe nge-Q345, 16Mn, Q390, St52-3, njll.
Amashubhu ayisikwele ahlukaniswe amashubhu ayisikwele ajwayelekile kazwelonke, amashubhu ayisikwele ajwayelekile aseJapan, amashubhu ayisikwele ajwayelekile aseBrithani, amashubhu ayisikwele ajwayelekile aseMelika, amashubhu ayisikwele ajwayelekile aseYurophu kanye namashubhu ayisikwele angajwayelekile ngokuya ngamazinga okukhiqiza.
Amapayipi ayisikwele ahlukaniswa ngokuya ngomumo wesigaba:
(1) Ishubhu lesikwele lesigaba esilula - ishubhu lesikwele, ishubhu elingunxande eliwugqinsi.
(2) Ipayipi eliyisikwele elinengxenye eyinkimbinkimbi - ipayipi eliyisikwele eliwugqinsi elimise okwembali, ipayipi eliyisikwele eliwugqinsi elivulekile, ipayipi eliyisikwele eliwugqinsi oluwugqinsi olumise okukhethekile kanye nepayipi eliyisikwele eliwugqinsi olumise okukhethekile.
Ngokusho kokwelashwa okungaphezulu, ipayipi eliyisikwele lodonga eliwugqinsi lihlukaniswe: ipayipi eliyisikwele eliwugqinsi elishisayo, ipayipi eliyisikwele eliwugqinsi, ipayipi eliyisikwele eliwugqinsi, ipayipi eliyisikwele eliwugqinsi kanye nepayipi eliyisikwele eliwugqinsi.
Amashubhu ayisikwele anezindonga eziwugqinsi ahlukaniswa ngokuya ngokusetshenziswa kwawo - 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 ayisikwele emishayo yensimbi namakholomu, namashubhu ayisikwele ngezinjongo ezikhethekile
Amashubhu ayisikwele ahlukaniswa ngokuqina kodonga - amashubhu ayisikwele odonga oluwugqinsi, amashubhu ayisikwele odonga oluqinile namashubhu ayisikwele odonga
Ifomula yokubala isisindo sepayipi eliyisikwele eliwugqinsi: 4 * ukujiya kodonga * (ubude bodonga oluseceleni) * 7.85
Ifomula yokubala yesisindo sepayipi elingunxande: {(umjikelezo ÷ 3.14) - ukujiya kodonga} * ukujiya kodonga * 0.02466
Ukucaciswa okuphezulu komugqa wokukhiqiza ipayipi elingunxande we-Process Institute ngu-500mm * 500mm * 19mm, okungeyesibili emhlabeni. Umugqa omkhulu wokukhiqiza ishubhu yesikwele esingu-26 inch weNippon Steel emhlabeni ungu-550mm * 550mm * 22mm. Njengamanje, ukucaciswa okukhulu kwepayipi elingunxande emazweni aseYurophu naseMelika kungu-400 * 400 * 12.7mm.
Eminyakeni yamuva nje, ngokutshalwa kwezimali kombuso ekwakhiweni kwezakhiwo ezinkulu, iyanda imisebenzi emikhulu kamasipala neyokwakha ezweni lonke ethathe uhlobo lwesakhiwo sensimbi. Ngenxa yezinzuzo zokubukeka okuhle, ukucindezeleka okunengqondo kanye nokwelashwa okulula kwama-node, ubukhulu obukhulu be-tube yesikwele obuyindilinga obuwunxande busetshenziswa kabanzi esakhiweni sesikhungo sezindiza iTruss structure system kanye nohlelo lokusekela udonga lwamakhethini lwezindawo zemidlalo kanye nezikhungo zeConvention kanye nemibukiso zibanzi. esetshenziswa njengamalungu ensimbi. Kodwa-ke, ekusebenzeni okusebenzayo, amapayipi ensimbi angama-square kanye nama-rectangular nawo ahlangabezana nezinkinga ezithile ezidinga ukuxazululwa ngokuphuthumayo.
Ukuze unciphise isisindo somuntu siqu futhi uthuthukise ukusebenza kokuphepha njengokumelana nokuzamazama komhlaba kanye nokumelana nomthelela, insimbi enamandla amakhulu isetshenziswe kabanzi ekhaya nakwamanye amazwe, futhi umkhawulo wamandla wezinto ezibonakalayo usufinyelele ku-630mpa noma ngaphezulu. Amandla aqinile ensimbi eyisisekelo yesikwele kanye nepayipi elingunxande elikhiqizwa inqubo lingafinyelela ku-630mpa, libekwe kuqala emhlabeni ngokwebanga lamandla omkhiqizo. Amandla amakhulu emikhiqizo yolayini wokukhiqiza i-Nippon Steel e-Japan ama-550MPa kuphela, nomehluko ocishe ube ngu-15%.
Ubukhulu obukhulu bethubhu yesikwele kanye ne-rectangular ekhiqizwa inqubo ngu-19mm. Ubukhulu obukhulu abubonakali kuphela ekugqineni okuphelele, kodwa futhi nasekugqileni okuhlobene komkhiqizo. Ugqinsi luyinkomba ebalulekile yobunzima bokugoba okubandayo. Ishubhu yesikwele ivezwa isilinganiso sokuqina konqenqema. Njengamanje, kukholelwa ukuthi ekhaya nakwamanye amazwe lapho isilinganiso sogqinsi singaphansi kwe-10, umkhiqizo unobunzima bokwenza okuphezulu. Ngepayipi yesikwele kanye ne-rectangular ekhiqizwa inqubo, isilinganiso sokuqina komkhawulo womkhiqizo onesigaba esincane nobukhulu obukhulu bodonga lungafinyelela ku-7, njenge-100mm * 100mm * 14mm, 120mm * 120mm * 16mm, njll.
Ipayipi eliyisikwele eliwusayizi omkhulu elibandayo elakhiwe ngensimbi egoqwe eshisayo engu-B490RNQ lihlangabezana ngokugcwele futhi lidlule izidingo zezinga lezwe lonke le-Q345B ngokwezakhiwo zemishini ekamelweni lokushisa, izakhiwo zalo zokwakheka nokucubungula zilingana noma zingcono kune-Q345B, futhi isilinganiso sesivuno sihlangabezana nezidingo zokuzamazama komhlaba zokucaciswa kwemboni yezokwakha kazwelonke. Ngesikhathi esifanayo, ukusebenza kwayo kwezinga lokushisa eliphezulu kungcono kakhulu kune-Q345B yezinga elifanayo. Ku-600, amandla okukhiqiza we-B490RNQ ahlala ku-310mpa, ephakeme kakhulu kuno-2/3 wamandla okukhiqiza izinga lokushisa, kuyilapho amandla okukhiqiza e-Q345B anogqinsi olungaphezu kuka-8mm ngenqubo engu-500 engaphansi kuka-2/3 amandla esivuno segumbi lokushisa.
