Imibhobho iya kuhanjiswa ngokwesiqhelo njengoko yenziwe.Umbhobho osebenza ngokubanda uya kutsalwa emva kokuba ubugcisa bugqityiwe.
Ukuba inkqubo yokwenziwa kwe-welding ye-resistance isetyenzisiweyo, i-welds iya kususwa kwiindawo zangaphakathi nangaphandle zombhobho ukufumana i-weld egudileyo kunye ne-contour yombhobho.Amaso e-weld kumphezulu ongaphakathi akanakususwa ukuba oku kungenxa yothintelo lwesixhobo okanye umbhobho wedayamitha.
Uhlobo lokuphela kombhobho lwe-JIS G 3452
Umbhobho Ukuphela Ukukhetha
Uhlobo lwesiphelo sombhobho we-DN≤300A/12B: i-threaded or flat end.
Uhlobo lwesiphelo sombhobho we-DN≤350A/14B: isiphelo esicaba.
Ukuba umthengi ufuna i-beveled end, i-angle ye-bevel yi-30-35 °, ububanzi be-bevel bombhobho wentsimbi yentsimbi: max 2.4mm.
Qaphela: Kwi-JIS G 3452, kukho uthotho lwe-A kunye no-B lwedayamitha ye-DN.Apho u-A elingana ne-DN, iyunithi ithi mm;B ilingana ne-NPS, iyunithi ingaphakathi.
Iimfuno zoMbhobho onemisonto eziPheleleyo
Imibhobho enemisonto iya kwenziwa ngokunika iziphelo zombhobho iintambo ze taper njengoko kuchaziwe kwi-JIS B 0203, kunye nokufaka enye yeziphelo eziphothiweyo ngohlobo olujijeweyo (emva koku ekubhekiselwa kulo njengesokethi) ehambelana ne-JIS B 2301 okanye i-JIS B 2302.
Ukuphela kombhobho ngaphandle kwesokethi kuya kukhuselwa ngendandatho yokukhusela intambo okanye ezinye iindlela ezifanelekileyo.
Imibhobho enemisonto inokubonelelwa ngaphandle kweesokethi ukuba icaciswe njalo ngumthengi.Ukuhlolwa kwemisonto ye taper kuya kuhambelana ne-JIS B 0253.
Ukwakhiwa kweekhemikhali ze-JIS G 3452
Iimfuno eziqhelekileyo zohlalutyo lweekhemikhali kunye neendlela zesampula zohlalutyo lwe-thermal ziya kuhambelana ne-JIS G 0404 igatya 8. Indlela yohlalutyo lwe-thermal iya kuhambelana nemigangatho ye-JIS G 0320.
| Uphawu lwebakala | P (Phosphorus) | S (Sulfur) |
| SGP | ubuninzi 0.040% | ubuninzi 0.040% |
Amanqanaba aphezulu e-phosphorus kunye ne-sulfure anciphisa ukusebenza kunye neepropati ze-mechanical zensimbi kwaye zithandwa kakhulu kwi-brittleness ngexesha le-welding.Ngoko ke, umgangatho kunye ne-weldability ye-carbon steel pipes inokuqinisekiswa ngokunciphisa i-phosphorus kunye nomxholo wesulfure.
Ezinye izinto zokudibanisa nazo zingongezwa njengoko zifunwa.
IiPropati zoomatshini ze-JIS G 3452
Iimfuno jikelele zovavanyo lomatshini ziya kuhambelana nesolotya lesi-7 kunye nelesi-9 le-JIS G 0404. Nangona kunjalo, kwiindlela zesampulu ezinikwe kwi-7.6 ye-JIS G 0404, kuphela indlela yesampulu A esebenzayo.
Uvavanyo lwe-tensile: Indlela yovavanyo iya kuhambelana nemigangatho ye-JIS Z 2241.

Ipropati yoKutyabeka
Kwiqondo lobushushu begumbi (5℃~35℃), i-weld i-perpendicular ukuya kwicala loxinzelelo.Gxininisa umboniso phakathi kwamaqonga amabini de umgama H phakathi kwamaqonga ufikelela kwisibini kwisithathu sobubanzi obungaphandle beziko lombhobho wentsimbi, uze ukhangele iintanda.
Ukubanda
Xa i-DN≤50A, yenza uvavanyo lokugoba.
Xa ugoba kwi-radius yangaphakathi ye-90 ° yamaxesha angama-6 ububanzi bangaphandle bombhobho, isiqwenga sovavanyo asiyi kuvelisa nayiphi na imicu.Ngaphambi kokugoba, linganisa i-engile yokugoba ukusuka kwindawo ethe tye.
Uvavanyo lweHydraulic okanye uvavanyo olungonakalisi (NDT)
Umbhobho ngamnye kufuneka ube luVavanyo lweHydraulic okanye uvavanyo olungenakonakala.
Uvavanyo lweHydraulic
Umbhobho kufuneka umelane ne-2.5MPa ubuncinane ubuncinane be-5 s, ngaphandle kokuvuza.
Uvavanyo olungonakalisi
Iimpawu zovavanyo ezingonakalisi zingasetyenziselwa uhlolo lwe-ultrasonic okanye lwe-eddy lwangoku, kwaye umbhobho uya kuhlangabezana nezi mpawu zilandelayo zovavanyo ezingonakalisi.
Ukuhlolwa kwe-ultrasonic, iisampuli zereferensi ezichazwe kwi-JIS G 0582 eziqulethe imigangatho yereferensi yeklasi ye-EU iya kusetyenziswa njengenqanaba le-alamu;naluphi na uphawu olusuka kumbhobho olulingana okanye olukhulu kunomgangatho we-alam luya kusetyenziswa njengenqanaba le-alam.umqondiso uya kusetyenziswa njengenqanaba le-alam;Naluphi na uphawu olusuka kumbhobho olulingana okanye olukhulu kunomgangatho we-alam luya kuba sisizathu sokwaliwa.
Kuhlolo lwangoku lwe-eddy, imiqondiso esuka kwiisampulu zereferensi equlethe imigangatho yereferensi yodidi lwe-EZ njengoko kuchaziwe kwi-JIS G 0583 iya kusetyenziswa njengemigangatho ye-alam;Naluphi na umqondiso olingana okanye omkhulu kunomgangatho we-alam ukusuka kumbhobho uya kuba sisizathu sokwaliwa.iya kusebenza njengenqanaba le-alam;Naluphi na umqondiso osuka kumbhobho olingana okanye omkhulu kunomgangatho we-alam uya kuba sisizathu sokwaliwa.Ngokwengqiqo yomenzi, inqanaba le-alam elibukhali elingaphantsi komqondiso womgangatho wesalathiso ochaziweyo linokusetyenziswa.
Ezinye iindlela zovavanyo ezingonakalisi nazo zingasetyenziswa, umz. ukufunyaniswa kokuvuza okuzenzekelayo njengoko kuchaziwe kwi-JIS G 0586.
Itshathi yobunzima bombhobho kunye nokunyamezelwa koMda
Steel Pipe Weight Calculation Formula
Ukucinga ukuba i-1 cm3 yentsimbi ibe yi-7.85g ubunzima
W=0.02466t(Dt)
W: ubunzima beyunithi yombhobho (kg / m);
t: ubukhulu bodonga lombhobho (mm);
D: ngaphandle kobubanzi bombhobho (mm);
0.02466: into yokuguqula ukufumana i-W;
Isondezwe kumanani amathathu abalulekileyo ngokuhambelana neJIS Z 8401, umthetho A.
Itshathi yobunzima bombhobho kunye nokunyamezelwa koMda
aIdayamitha yegama iya kuba ngokwelinye lamagama A okanye B kwaye ibonakaliswe ngokuncamathisela unobumba A okanye B, nokuba yeyiphi na indlela esetyenziswayo, emva kwenani ledayamitha.
bKwiindawo ezilungisiweyo zendawo, ukunyamezela kule tafile akusebenzi.
cKwimibhobho enedayamitha engama-350A okanye ngaphezulu, umlinganiselo wedayamitha yangaphandle unokutshintshwa ngobude obujikelezileyo, apho unyamezelo olusetyenziswayo luya kuba yi-0.5 %.Ubude obulinganiselweyo obulinganisiweyo (I) buya kuguqulelwa kwidayamitha yangaphandle (D) kusetyenziswa le fomula ilandelayo.
D=l/Π
D: ububanzi bangaphandle (mm);
l: ubude obujikelezayo (mm);
Π: 3.1416.
Imbonakalo yombhobho wentsimbi
Imbonakalo
Indawo yangaphakathi nangaphandle yombhobho iya kuba lula kwaye ikhululekile kwiziphene ezingathandekiyo ukuyisebenzisa.
Umbhobho uya kuba ngokuthe tye, kunye neziphelo kwii-angles ezichanekileyo kwi-axis yombhobho.
Ukulungisa isiphene
Umbhobho omnyama (umbhobho wentsimbi ngaphandle konyango lokuchasana nomhlwa) unokulungiswa ngokusila, umatshini, okanye ezinye iindlela, kwaye indawo elungisiweyo iya kuba mpuluswa ecaleni kwekhonto yombhobho.
Nangona kunjalo, ubukhulu bodonga obulungisiweyo bugcinwa ngaphakathi kokunyamezela okuchaziweyo.
Ukwaleka komphezulu
Nayiphi na okanye yomibini imiphezulu yombhobho ingagqunywa umz., i-zinc-rich coating, epoxy coating, primer coating, 3PE, FBE, njl.
Iigalati ze-JIS G 3452
Idiphu eshushu iGalvanizing
Imibhobho yensimbi, ukuba ifakwe igalvanized, imibhobho enemisonto kunye neziseko kufuneka ifakwe nge-zinc ngaphambi kokuqinisa imicu.
Ukucocwa komphezulu wentsimbi ngokucokisekileyo ngokuqhunyiswa kwesanti, ukuchola, njalo njalo, kulandele ukugalelwa kwediphu eshushu.
Kwi-zinc-coating, i-distilled zinc ingot Udidi loku-1 oluchazwe kwi-JIS H 2107 okanye i-zinc enomgangatho olinganayo ubuncinane kule nto iya kusetyenziswa.
Ezinye iimfuno eziqhelekileyo zokugquma i-zinc zichazwe kwi-JIS H 8641.
Uvavanyo lweGalavanization
Indlela yoVavanyo Ngokwendlela yokuvavanya echazwe kwiNqaku lesi-6 le-JISH0401, i-specimen ifakwe kwisisombululo se-sulfate yethusi, i-1 min 5 amaxesha, kwaye i-specimen ihlolwe ukuze ibone ukuba ifikelela ekupheleni.
Ukumakishwa kwe-JIS G 3452
