Umbhobho wentsimbi ye-1 engenan-. Umbhobho wensimbi unamacandelo angenawo, asetyenziswa ngokubanzi ukuhambisa umbane, njengeoyile, igesi yendalo, igesi, amanzi kunye nezinye izinto eziqinileyo. Xa kuthelekiswa nentsimbi eqinileyo enje ngentsimbi ejikelezayo, umbhobho ongenamthungo unamandla afanayo okugoba kunye nokuqina kunye nobunzima bokukhanya. Isetyenziswa ngokubanzi ekwenziweni kweenxalenye zesakhiwo kunye namacandelo oomatshini, afana nepetroleum drill pipe, imoto yokuhambisa imoto, isakhelo sebhayisikile kunye ne-scaffold yentsimbi esetyenziswe kulwakhiwo. Inokuphucula inqanaba lokusetyenziswa kwezinto, yenza lula inkqubo yokuvelisa, gcina izinto kunye nexesha lokuqhubekeka ngokusebenzisa umbhobho ongenamthungo ukwenza izinto zeringi, njengokugungqa iringi ethwele, umkhono wejack, njl. Ityhubhu engenamthungo nayo yinto ebalulekileyo kuzo zonke iintlobo zesiqhelo izixhobo. Umgqomo kunye nomgqomo zenziwe ngetyhubhu yentsimbi. Ngokobume bendawo enqamlezayo, imibhobho yentsimbi ingahlulwa ibe ngumbhobho ojikelezayo kunye nombhobho okhethekileyo. Kuba indawo yesangqa yeyona inkulu phantsi kwemeko yomjikelezo olinganayo, ulwelo oluninzi lunokuhanjiswa ngumbhobho wesetyhula. Ukongeza, xa icandelo lesangqa liphethe uxinzelelo lwangaphakathi okanye lwangaphandle, amandla afanayo. Ke ngoko, uninzi lweetyhubhu ezingenamthungo ziityhubhu ezijikelezileyo, ezahlulwe zaziqengqeleka zishushu kunye nokuqengqeleka okubandayo. Izinto eziqhelekileyo: 20 #, 45 #, Q345, 20g, 20Cr, 35CrMo, 40Cr, 42CrMo, 12CrMo, 12Cr1MoVG, 15CrMoG, njl. Uthotho lwentsimbi engenasici luhlobo lwentsimbi ejikelezileyo, nesetyenziswa ngokubanzi kwi-petroleum, imichiza, ezonyango, ukutya, ishishini elikhanyayo, izixhobo zoomatshini kunye neminye imibhobho yemizi-mveliso kunye namacandelo oomatshini. Ukongeza, xa ukugoba kunye nokuqina kwamandla kuyafana, ubunzima bukhaphukhaphu, ke kukwasetyenziswa ngokubanzi ekwenzeni iindawo zoomatshini kunye nezakhiwo zobunjineli. Kananjalo isetyenziselwa ifenitshala, ikhitshi, njl., Izinto eziqhelekileyo: 201, 304, 316, 316L, 310, 310S, njl.
2.Iplate yensimbi: yintsimbi ethe tyaba ngentsimbi etyhidiweyo kwaye icinezelwe emva kokupholisa. Ithe tyaba kwaye buxande, kwaye inokuqengqeleka ngqo okanye isikwe kumcu obanzi wentsimbi. Isitya sensimbi sahlulwe sasishushu kakhulu kwaye saziqengqa ngokubandayo ngokungqengqa. Ngokobungakanani bepleyiti yesinyithi, ipleyiti yentsimbi ethe nca Ububanzi bephepha ngu-500-1500 mm; Ububanzi ipleyiti zamafu - 600-3000 mm. Ngokweentlobo zentsimbi, kukho intsimbi yesiqhelo, intsimbi ekumgangatho ophezulu, intsimbi ye-alloy, intsimbi yasentwasahlobo, intsimbi engenasici, isixhobo sesinyithi, intsimbi enganyangekiyo, ethwele intsimbi, intsimbi yesilicon kunye nentsimbi esulungekileyo yoshishino; Ngokwokusetyenziswa kobuchwephesha, kukho ipleyiti yeoyile ye-oyile, ipleyiti yoqweqwe, ipleyiti yokuthintela iimbumbulu, njl. Ngokutsho umphezulu ukutyabeka, kukho iphepha iqaqanjiswa, tinplate, ipleyiti lead, ipleyiti intsimbi edityanisiweyo, njl izinto eziqhelekileyo: Q235, 16Mn (q355b), 20 #, 45 #, 65Mn, 40Cr, 42CrMo, 304, 201, 316 njl.
3. Umbhobho otyhidiweyo: umbhobho wensimbi otyhidiweyo, owaziwa nangokuthi umbhobho odibeneyo, ngumbhobho wensimbi owenziwe ngeplate yensimbi okanye umgca emva kokugoba nokwenza, kunye nobude obude obuqhelekileyo beemitha ezi-6. Inkqubo imveliso umbhobho ngentsimbi welding ilula, ukusebenza yemveliso iphezulu, iindidi kunye nokubalula ngaphezulu, izixhobo utyalo-mali ingaphantsi, kodwa amandla jikelele asezantsi ngaphezu umbhobho intsimbi ingenamthungo. Umbhobho wentsimbi otyhidiweyo wahlulwe waba ngumbhobho oshushu othe tyaba kunye nombhobho oshushu ojikelezayo ngohlobo lwe weld. Ukwahlulahlulwa ngokwendlela yemveliso: inkqubo yokuhlela - iarc ipipe edibeneyo, ipipe yokuxhathisa, (ubukhulu obuphezulu, isantya esisezantsi) umbhobho werhasi, welding umbhobho. Straight umthungo iwelding isetyenziselwa ubukhulu obuncinci obunamathele kumbhobho, ngelixa i-welding spiral isetyenziselwa umbhobho omkhulu otyhidiweyo; Ngokombono wokuphela kombhobho wensimbi, unokuhlulahlula umbhobho ojikelezayo kunye ne-special-shaped (square, rectangular, etc.) Ngokwezixhobo ezahlukeneyo kunye nokusetyenziswa, inokwahlulahlulwa ibe ngumbhobho wentsimbi ohambisa umbhobho wentsimbi, i-low-pressure fluid ehambisa umbhobho wentsimbi e-welding, i-belt conveyor roller welding pipe yensimbi, njl njl. ngexabiso eliphantsi, ukukhula ngokukhawuleza. Amandla omoya umbhobho welding ngokubanzi ngokubanzi ngaphezu umbhobho welding ngqo. Ingasetyenziswa ukuvelisa ubukhulu ngombhobho welding kumbhobho engamxinwa blank, kwaye kananjalo ingasetyenziswa ukuvelisa ubukhulu ezahlukeneyo kumbhobho welding kunye ububanzi efanayo blank. Kodwa xa kuthelekiswa nobude obufanayo bombhobho womthungo othe ngqo, ubude be-weld bonyuka nge-30 ~ 100%, kwaye isantya semveliso sisezantsi. Ububanzi obukhulu okanye ipayipi eshinyeneyo edityanisiweyo ihlala yenziwe nge-billet yentsimbi ngokuthe ngqo, ngelixa umbhobho omncinci odibeneyo kunye nombhobho odibeneyo obiyelweyo ufuna kuphela ukuhanjiswa ngokuthe ngqo ngumtya wentsimbi. Ke emva kokucoca okulula, ukuzoba ucingo kulungile. Ukulungiselela ukuphucula ukunganyangeki kombhobho wentsimbi, umbhobho wentsimbi ngokubanzi (umbhobho omnyama) waqiniselwa. Zimbini iintlobo zombhobho zentsimbi kwalenza, ukutshisa okushushu kunye nokudibanisa i-electro galvanizing. Ubukhulu be-galvanizing eshushu-eshushu bukhulu, kwaye iindleko ze-electro galvanizing ziphantsi. Izinto eziqhelekileyo zombhobho odibeneyo zi: Q235A, Q235C, Q235B, 16Mn, 20Mn, Q345, L245, L290, X42, X46, X60, X80, 0Cr13, 1Cr17, 00cr19ni11, 1Cr18Ni9, 0cr18ni11nb, njl.
4. Umbhobho ohlanganisiweyo: umbhobho odibeneyo uzibophelele kwimveliso yeentlobo ezahlukeneyo zemibhobho ezibhijelweyo kunye neentsimbi zepensiti ezinamacala ajikelezayo kunye namaringi ombane, kwaye ziguqulwa ngokwesiseko semigaqo efanayo kunye neemodeli zezixhobo zombhobho ezibhijelwe ngokwesiko. Umsebenzi wokwandisa iiparameter zezixhobo zokuqengqa ityhubhu ngama-30% ugcwalisa isikhewu esingakwaziyo ukuvelisa izixhobo zemveli. Inokuvelisa imibhobho yentsimbi enobubanzi obungaphezulu kwama-400 kunye nobukhulu bodonga obungu-8-100 mm. Umbhobho ozibhijeleyo usetyenziswa kakhulu kwi-petroleum, imichiza, ukuhanjiswa kwegesi yendalo, ukufumba kunye nokuhanjiswa kwamanzi edolophini, ukufudumeza, ukuhanjiswa kwegesi kunye nezinye iiprojekthi. Izinto eziphambili ziyi-Q235A, Q345B, 20, 45, 35cimo, 42cimo, 16Mn, njl
