I-JIS G 3456 yoHlelo lweBanga
Umgangatho we-JIS G 3456 unamabakala amathathu ngokokuqina kombhobho.
I-STPT370,STPT410 kunye ne-STPT480
Bamele iityhubhu ezinobuncinci bokuqina be-370, 410, kunye ne-480 N/mm² (MPa) ngokulandelelanayo.
Iimpahla ezingekasilwa
Imibhobho iya kwenziwa ngentsimbi ebuleweyo.
Insimbi ebuleweyo luhlobo olukhethekileyo lwensimbi olubonakaliswe ngokongezwa kwezinto ezithile, ezifana ne-aluminium kunye ne-silicon, ngexesha lenkqubo yokunyibilika ukufunxa nokubopha i-oksijini kunye nezinye izinto ezinobungozi kwintsimbi.
Le nkqubo isusa ngokufanelekileyo iigesi kunye nokungcola, ngaloo ndlela iphucula ukucoceka kunye nokufana kwentsimbi.
I-JIS G 3456 Iinkqubo zokuVelisa
Iveliswe ngokusebenzisa inhlanganisela efanelekileyo yeenkqubo zokuvelisa i-tube kunye neendlela zokugqiba.

KubaSTPT 480umbhobho womgangatho, kuphela umbhobho wentsimbi ongenamthungo oya kusetyenziswa.
Ukuba i-welding ye-resistance isetyenzisiweyo, i-welds kwindawo yangaphakathi nangaphandle yombhobho iya kususwa ukuze ifumane i-weld egudileyo.
Ukuphela kombhobho
Umbhobho kufuneka ubeisiphelo esicaba.
Ukuba umbhobho kufuneka uqhutywe kwi-beveled end, ngenxa yobunzima bodonga ≤ 22mm umbhobho wensimbi, i-angle ye-bevel yi-30-35 °, ububanzi be-bevel bombhobho wensimbi yensimbi: max 2.4mm.
Ubukhulu bodonga olungaphezulu kwe-22mm yentsimbi yombhobho othambekileyo ekupheleni, ngokubanzi kusetyenzwa njenge-bevel edibeneyo, ukuphunyezwa kwemigangatho kunokubhekisela kwiimfuno ezifanelekileyo ze-ASME B36.19.
Unyango olushushu
Khetha inkqubo efanelekileyo yonyango lobushushu ngokwebakala kunye nenkqubo yokuvelisa.

Ukunyamezela ukuBunjwa kweMichiza
Imibhobho yentsimbi engenamthungo iya kuba phantsi konyamezelo kwiThebhile 3 ye-JIS G 0321.
Imibhobho yentsimbi echasayo iya kuba phantsi kokunyamezelana kwiThebhile 2 ye-JIS G 0321.
Uvavanyo lwe-Tensile ye-JIS G 3456
Iindlela zovavanyo: Iindlela zovavanyo ziya kuhambelana nemigangatho ekwi-JIS Z.2241.
Umbhobho uya kuhlangabezana neemfuno ezinikwe kwiThebhile 4 zokuqina kokuqina, amandla esivuno, kunye nobude.
Isiqwenga sovavanyo esisetyenzisiweyo siya kuba seNombolo ye-11, iNo.
I-diameter ye-Test piece No. 4 iya kuba yi-14 mm (ubude be-gauge 50 mm).
Iziqwenga zovavanyo ze-11 kunye neNombolo ye-12 ziya kuthathwa ngokuhambelana ne-axis yombhobho,
Iziqwenga zovavanyo No. 14A kunye no.
kunye nesiqwenga soVavanyo lwe-5, kwi-perpendicular kwi-axis yombhobho.
Isiqwenga sovavanyo lwe-12 okanye iNombolo ye-5 ethathwe kwi-electric resistance welded steel pipe ayiyi kuba ne-weld.
Kuvavanyo lwe-tensile lwemibhobho engaphantsi kwe-8 mm ubukhulu obuqhutywe kusetyenziswa isiqwenga soVavanyo esinguNombolo 12 okanye isiqwenga soVavanyo esinguNombolo 5, imfuneko yobude obunikwe kwiThebhile yesi-5 iya kusebenza.
Ukuzama ukuThwalaza
Kwiqondo lokushisa lokushisa (5 ° C - 35 ° C), thambisa i-specimen phakathi kwamaqonga amabini kude kubeumgama (H) phakathi kwabo ufikelela kwixabiso elichaziweyo kwaye emva koko ukhangele iintanda.
H=(1+e)t/(e+t/D)

Uvavanyo lokuBendability
I-Bendability isetyenziswa kwiibhobho ezinobubanzi obungaphandle be-60.5 mm okanye ngaphantsi.
Indlela yokuvavanya Kwiqondo lobushushu (5 ° C ukuya ku-35 ° C), bend iqhekeza lovavanyo malunga ne-mandrel de i-radius yangaphakathi ibe ngamaxesha angama-6 ububanzi obungaphandle bombhobho kwaye ukhangele iintanda.Kolu vavanyo, i-weld kufuneka ibekwe malunga ne-90 ° ukusuka kwindawo engaphandle ye-bend.
Uvavanyo lwe-Bendability lunokuthi luqhutywe ngokuhambelana nemfuno yokuba i-radius yangaphakathi iphindwe kane ububanzi bangaphandle bombhobho kunye ne-angle yokugoba yi-180 °.
Uvavanyo lweHydraulic okanye uvavanyo olungonakalisi (NDT)
Uvavanyo lwehydraulic okanye uvavanyo olungonakalisi luya kwenziwa kumbhobho ngamnye.
Uvavanyo lweHydraulic
Bamba umbhobho ubuncinane ubuncinane bexinzelelo lovavanyo lwe-hydraulic oluchazwe ubuncinane imizuzwana emi-5 kwaye uqaphele ukuba umbhobho uyakwazi ukumelana noxinzelelo ngaphandle kokuvuza.
Ixesha le-Hydraulic lichazwe ngokweShedyuli yepayipi yensimbi.
