Ukuhlelwa kweBanga
I-JIS G 3454 inamabakala amabini ngokobuncinane besivuno sombhobho wensimbi ogqityiweyo.
STPG370, STPG410
Iinkqubo Zokuvelisa
Yenziwe kusetyenziswa ukudibanisa okufanelekileyo kweenkqubo zokuvelisa i-tube kunye neendlela zokugqiba.

Umbhobho wentsimbi osebenza ebandayo uya kutsalwa emva kokwenziwa.Ukuba kuyimfuneko, uMthengi unokuchaza unyango olushushu lwe-welds ye-STPG 410 yokuxhathisa ipayipi yensimbi edibeneyo.
Ukuba i-welding ye-resistance isetyenzisiweyo, i-welds kwindawo yangaphakathi nangaphandle yombhobho kufuneka isuswe ukuze ifumane i-weld egudileyo ecaleni kwe-contour yombhobho.Nangona kunjalo, ukuba kunzima ukususa i-weld kwindawo yangaphakathi, imeko edibeneyo ingagcinwa.
Idiphu eshushu iGalavanizing -iMbhobho emhlophe
Kubamhlopheumbhobho(imibhobho enikwe i-zinc-coating), indawo yokuhlolaumbhobho omnyama(imibhobho enganikwanga i-zinc-coating) iyakucocwa ngokuqhunyiswa kwesanti, ukucolwa, okanye ngolunye unyango phambi kokugalela idiphu eshushu.I-Zinc ye-galvanizing yediphu eshushu iya kuba yi-JIS H 2107 iBanga loku-1 ingot ye-zinc edibeneyo okanye i-zinc yomgangatho olinganayo okanye ongcono.
Ezinye iimfuno ngokubanzi zokugalela intsimbi zihambelana neJIS H 8641.
Ukwakhiwa kweekhemikhali ze-JIS G 3454
Izinto ngokubanzi zeemvavanyo zohlalutyo kunye neendlela zesampulu kunye nohlalutyo ziya kuhambelana ne-JIS G 0404 into yesi-8 (Ukwakheka kweeKhemikhali).
Indlela yohlalutyo iya kuhambelana ne-JIS G 0320.

IiPropati zoomatshini be-JIS G 3454
Iimfuno ngokubanzi zovavanyo lomatshini zihambelana ne-JIS G 0404 Igatya lesi-7 (IiMfuno Jikelele) kunye neGatya lesi-9 (iiPropati zoomatshini).
Nangona kunjalo, indlela yokuqokelela i-specimen yovavanyo lomatshini iya kuhambelana ne-JIS G 0404 Igatya 7.6 (Iimeko zokuqokelelwa kwemifanekiso kunye neesampuli), Uhlobo A.
Abavavanyi bombhobho baya kwenza iimvavanyo ngokuhambelana ne-JIS Z 2241 kunye namandla okuqina, amandla emveliso, kunye nobude obuya kuhambelana neThebhile 3.
Nangona kunjalo, kwiityhubhu ezingaphantsi kwe-8 mm ubukhulu, ubude buya kuhambelana neThebhile 4 kwiimvavanyo ze-tensile usebenzisa i-12 okanye i-5 yesampuli.
Uvavanyo lokucaba
Ubushushu bovavanyo kufuneka bube liqondo lobushushu begumbi (5 ~ 35 ℃), umzekelo ubekwe phakathi kwamacwecwe amabini acaba kwaye ucinezelwe de umgama H phakathi kwamacwecwe ungaphantsi kwexabiso elikhankanyiweyo, xa umfuziselo ucandiwe, jonga ukuba kukho ukuqhekeka. kumphezulu webloko yesampula yombhobho wentsimbi.
Xa H=2/3D, khangela i-weld yokuqhekeka.
Xa H=1/3D, khangela iintanda kwiindawo ngaphandle kwe-weld seam.
Umbhobho wensimbi ongenamthungo unokukhululwa kuvavanyo lwe-flattening, kodwa ukusebenza kombhobho kufuneka kuhambelane nemimiselo.
Ukugoba uvavanyo
Isebenza kwimibhobho ene-diameter yangaphandle ≤ 40A (48.6mm).
Lo mzekelo awuyi kuqhekeka xa ugobile kwi-90 ° kunye ne-radius yangaphakathi yamaxesha ama-6 ngaphandle kwedayamitha yangaphandle.
Umthengi unokucacisa i-angle yokugoba ye-180 kunye / okanye i-radius yangaphakathi yamaxesha ama-4 ububanzi obungaphandle bombhobho.
Ukumelana nemibhobho edibeneyo, i-weld seam iya kufumaneka malunga ne-90 ° ukusuka kwindawo engaphandle ye-bend.
Uvavanyo lwe-Hydraulic okanye uvavanyo olungonakalisi
Yonke imibhobho kufuneka ivavanywe nge-hydraulically okanye ivavanywe ngokungonakalisi.
Nangona kunjalo, kwimibhobho emhlophe, oku ngokuqhelekileyo kwenziwa ngaphambi kokuba i-galvanizing.
Uvavanyo lwe-Hydrotesting okanye olungonakalisi luyindlela ebalulekileyo yokulawula umgangatho wemibhobho ukuqinisekisa ukhuseleko kunye nokuthembeka kwemibhobho ngexesha lofakelo kunye nokusetyenziswa.
Uvavanyo lweHydrostatic
Faka isicelo soxinzelelo oluphezulu kunoluchaziweyo lwe-hydraulic test kumbhobho kwaye ubambe ubuncinane imizuzwana emi-5 ukuze ubone ukuba umbhobho unokumelana noxinzelelo kwaye ukuba ukuvuza kwenzeka.

Uvavanyo olungonakalisi
Uvavanyo lwe-ultrasonic (UT) indlela iya kuhambelana ne-JIS G 0582. Nangona kunjalo, uvavanyo olungqongqo ngakumbi kunoluhlu lwe-UD lweziphene ezenziweyo lunokusetyenziswa kwakhona endaweni.
Indlela ye-Eddy yovavanyo lwangoku (ET) iya kuhambelana ne-JIS G 0583. Nangona kunjalo, inokuthi ithathelwe indawo ngovavanyo olungqongqo kunolwahlulo lwe-EY Artificial Defects.
Ngokuqinisekileyo, ezinye iindlela zokuvavanya ezingonakalisiyo ezihlangabezana nemilinganiselo zinokukhethwa endaweni.
Ukunyamezelwa kweDimensional
Ukunyamezela okungathandekiyo kubunzima bemibhobho yensimbi yokuchasana-welding isebenza kuphela kwi-resistance-welded welds yentsimbi yombhobho;ukunyamezelana okulungileyo akusebenzi.

Le fomyula ingentla luguqulelo olusekwe kuxinaniso lweetyhubhu zentsimbi ze-7.85 g/cm³ kwaye iziphumo zisondezwe kumanani amathathu abalulekileyo.
Itheyibhile yobunzima bombhobho wentsimbi
Iitshati zobunzima bombhobho zidlala indima ebaluleke kakhulu kwinkqubo yoyilo lwemibhobho, ubunjineli, ukuthenga, kunye nolwakhiwo, kwaye zisisalathiso esiyimfuneko nesibalulekileyo kubunjineli bemibhobho.
Iishedyuli zombhobho
Ishedyuli yombhobho yitafile esetyenziselwa ukulinganisa imilinganiselo yombhobho, ngokuqhelekileyo ukucacisa ubuninzi bodonga kunye nobukhulu obuqhelekileyo bombhobho.
IShedyuli 10, 20, 30, 40, 60 kunye ne-80 kwi-JIS G 3454.
Funda ngakumbi malungaubunzima bombhobho kunye neshedyuli yemibhobhongaphakathi komgangatho.
Imbonakalo
Umbhobho uya kuba ngokuthe ngqo kwaye iziphelo zawo ziya kuba zixhomekeke kwi-axis yombhobho.
Umgangatho wangaphakathi kunye wangaphandle wombhobho uya kugqitywa kakuhle kwaye ukhululekile kwiziphene ezingathandekiyo ukusebenzisa.
Ukunyangwa komphezulu kunokwenziwa ngokusila, ukucwangciswa, kunye nezinye iindlela zokujongana neziphene zomhlaba, kodwa ubuninzi emva konyango abukho ngaphantsi kobunzima obuncinci, kwaye ubume bombhobho buhlala buhambelana.
UKutyabeka komphezulu we-JIS G 3454
Umgangatho wangaphakathi nangaphandle wemibhobho yensimbi inokugqithwa ngeengubo ezichasene ne-anticorrosive, ezifana neengubo ezityebileyo ze-zinc, i-epoxy coatings, i-primer coatings, i-3PE, kunye ne-FBE.
Ukumakisha
Iityhubhu zentsimbi ezidlula uhlolo ziya kuphawulwa ngolu lwazi lulandelayo kwi-tube-by-tube basis.Nangona kunjalo, ukuba i-diameter encinci yangaphandle yeetyhubhu yenza kube nzima ukuphawula ityhubhu nganye ngabanye, iityhubhu zinokuthi zihlanganiswe kwaye inqwaba nganye imakwe ngendlela efanelekileyo.
Ulandelelwano lokumakisha aluchazwanga.Ukongeza, izinto ezithile zinokushiywa ngesivumelwano phakathi kwamaqela ekuhanjisweni, ngaphandle kokuba imveliso inokuchongwa.
