Ububanzi be-ASTM A106
Uhlobo lombhobho: umbhobho wentsimbi ongenamthungo.
NUbungakanani bombhobho ominal: Igubungela umbhobho wentsimbi ongenamthungo ovela kwi-DN6-DN1200 (NPS1/8-NPS48).
Ukutyeba kweendonga: Ubungqingqwa bodonga luyafuneka ukuhlangabezana neemfuno ezithile zeTheyibhile 1 yeASME B36.10M.
IBanga le-ASTM A106
I-ASTM A106 inamabakala amathathu ombhobho wentsimbi: iBanga A,IBanga B, kunye neBanga C.
Umahluko omkhulu phakathi kwamabanga amathathu kukubunjwa kweekhemikhali kunye neempawu zomatshini.
Izinto ze-ASTM A106 ezikrwada
Intsimbi iya kubulawa yintsimbi.
Intsimbi iveliswa kusetyenziswa inkqubo yokunyibilika eyiprayimari, enokuthi ibe yi-open-hearth, i-basic-oxygen, okanye i-furnace yombane, mhlawumbi idibaniswe ne-degassing eyahlukileyo okanye ukucocwa.
I-ASTM A106 Indlela yokuVelisa umbhobho wentsimbi engenamthungo
Umbhobho wentsimbi ongenamthungoiveliswa ngeendlela ezimbini: itsalwa ngokubanda kwaye ishushu igqitywe.
I-DN ≤ 40mm umbhobho wensimbi ongenamthungo unokutsalwa ngokubanda okanye ushushu-ugqitywe.
I-DN ≥ 50mm umbhobho wentsimbi ongenamthungo ushushu-ugqityiwe.
Unyango olushushu
Umbhobho wensimbi ongenamthungo ogqityiweyo we-ASTM A106 awufuni unyango lobushushu.
Iityhubhu zentsimbi ezingenamthungo ze-ASTM A106 ezitsalwa ngokubanda kufuneka ziphathwe ubushushu kumaqondo obushushu ≥ 650°C.
Ukuqulunqwa kwemichiza
I-ASTM A106 iBanga A, iBanga B, kunye neBanga C kubume bekhemikhali owona mahluko mkhulu ngumahluko phakathi komxholo we-C kunye no-Mn, umxholo wezinye izinto kumabakala ahlukeneyo unokuba nomahluko omncinci, kodwa ngokuqhelekileyo ukulawula uluhlu oluphantsi ngokwentelekiso.
Iipropati zoomatshini
Ubuncinane bobude kwi-2 in. (50 mm) buya kumiselwa ngolunxaki lulandelayo:
iiyunithi ze-intshi-phawundi:
e=625,000A0.2/UO.9
Sl iiyunithi:
e=1940A0.2/U0.9
e: ubude obuncinane kwi-2 ngo. (50 mm), %, isondezwe kwelona kufutshane 0.5%
A: indawo enqamlezileyo yomzekelo wovavanyo loxinzelelo, kwi2(mm2）ngokusekwe kububanzi obuchaziweyo bangaphandle okanye ububanzi besampulu echaziweyo kunye nobukhulu bodonga obuchaziweyo,isondezwe kweyona 0.01 ikufutshane2(1 mm2).
Ukuba ummandla obalwe ngolo hlobo ulingana okanye mkhulu kuno-0.75 ngo2(500 mm2), ngoko ixabiso le-0.75 ngaphakathi2(500 mm2) iya kusetyenziswa.
U: amandla okuqina acacisiweyo, i-psi (MPa)
Inkqubo yoVavanyo
I-ASTM A106 iqulethe iinkcukacha ezicacileyo zokwakheka kweekhemikhali, uhlalutyo lobushushu, iimfuno zepropathi yoomatshini, iimfuno zokugoba, iimvavanyo zokuthambisa, iimvavanyo ze-hydrostatic, kunye novavanyo olungonakaliyo lombane.
Ukubunjwa kweMichiza / Uhlalutyo lobushushu
Uhlalutyo lobushushu yinkqubo esetyenziselwa ukumisela umxholo wezinto zekhemikhali zomntu ngamnye kwintsimbi ukuze kuqinisekiswe ukuba ukubunjwa kweekhemikhali zezinto ezininzi kuhlangabezana neemfuno ze-ASTM A106.
Ukuzimisela kokwakhiwa kweekhemikhali kusekelwe kuhlalutyo lwe-thermal.Ingqwalasela ephambili kumxholo wekhabhoni, i-manganese, i-phosphorus, isulfure, kunye ne-silicon, umlinganiselo ochaphazela ngokuthe ngqo kwiipropati zombhobho.
IiMfuno zeTensile
Iityhubhu kufuneka zihlangabezane namandla athile okuqina, amandla esivuno, kunye neemfuno zobude.Oku kuqinisekisa amandla kunye nokuqina kombhobho kumaqondo okushisa aphakamileyo.
IiMfuno zokugoba
Iimvavanyo zokugoba zisetyenziselwa ukuvavanya ukuqina kunye nokuguqulwa kweplastiki yeetyhubhu xa ziphantsi koxinzelelo lokugoba ukuze kuqinisekiswe ukuthembeka kombhobho ngexesha lofakelo kunye nokusetyenziswa.
Iimvavanyo zokucaba
Uvavanyo lwe-Flattening lusetyenziselwa ukuvavanya i-ductility kunye nokuchasana nokuqhekeka kweetyhubhu zetsimbi.Olu vavanyo lufuna ukuba umbhobho uhlanjululwe kwinqanaba elithile ngaphandle kokuqhekeka ukubonisa umgangatho wezinto eziphathekayo kunye nokufaneleka kobuchwepheshe bokucubungula.
Uvavanyo lweHydrostatic
Uvavanyo lwe-Hydrostatic luyinyathelo elibalulekileyo ekuhloleni amandla okunyanzeliswa kombhobho wensimbi ngokufaka uxinzelelo oluphezulu kunokuba lufunwa ngumgangatho wokuqinisekisa ukunyaniseka kwesakhiwo kunye nokungabikho kokuvuza.
Uvavanyo loMbane olungonakaliyo
Uvavanyo loMbane olungonakaliyo (umzekelo, uvavanyo lwe-ultrasonic okanye uvavanyo lwe-electromagnetic) lusetyenziselwa ukuchonga iziphene zangaphakathi kunye nangaphezulu ezifana nokuqhekeka, ukufakwa, okanye imingxuma kwiityhubhu zentsimbi ukuqinisekisa umgangatho wemveliso.
Ukunyamezelwa kweDimensional
IMisa
Ubunzima bokwenene bombhobho kufuneka bube kuluhlu lwe97.5% - 110%yobunzima obuchaziweyo.
Imibhobho ekwi-NPS 4 [DN 100] nangaphantsi inokulinganiselwa kumaqashiso afanelekileyo;
Imibhobho emikhulu kune-NPS 4 [DN 100] iya kulinganiswa ngokwahlukeneyo.
Ububanzi bangaphandle
Kwi-OD> 250 mm (10 in) iibhubhu, ukuba ukuchaneka okuphezulu kwe-OD kuyadingeka, ukuhluka okuvumelekileyo kwe-OD yi-±1%.
Kwi-ID> 250 mm (i-10 in) iibhubhu, ukuba ukuchaneka okuphezulu kwe-ID kuyadingeka, ukuhluka kwe-ID evumelekileyo yi-± 1%.
Ukutyeba
Ubuncinci bendonga yodonga = 87.5% yodonga oluchaziweyo.
Ubude
Ubude obubodwa obungenamkhethe: 4.8-6.7 m [16-22ft].I-5% yobude ivumelekile ukuba ibe ngaphantsi kwe-4.8 m [16 ft], kodwa ingabi mfutshane kune-3.7 m [12 ft].
kabini ubude random: Obona bude buncinane buziimitha eziyi-10.7 [35 ft] kwaye ubude obuncinane buziimitha ezi-6.7 [22 ft].Iipesenti ezintlanu zobude zivumelekile ukuba zibe ngaphantsi kwe-6.7 m [22 ft], kodwa zingabi mfutshane kune-4.8 m [16 ft].
Unyango lweziphene zoMphezulu
Ukumiselwa kweziphene
Xa iziphene zomhlaba zivela kwiibhubhu ezidlula i-12.5% yobukhulu bodonga oluqhelekileyo okanye ukugqithisa ubuninzi bodonga obuncinane, iziphene kufuneka zisuswe ngokusila nje ukuba udonga oluseleyo luyi-87.5% okanye ngaphezulu kwexabiso elichaziweyo.
Iziphene ezingeyonzakali
Ukwenza unyango olungaphezulu ngokuhambelana neemfuno zenkqubo, ezi ziphene zilandelayo zingenabungozi kufuneka zisuswe ngokusila:
1. Amanqaku omatshini kunye nokukrazula - njengamanqaku ekheyibhile, izibonda, amanqaku esikhokelo, amanqaku okuqengqeleka, imikrwelo yebhola, i-indentations kunye namanqaku okungunda, kunye nemingxuma, ekungekho nanye kuzo eya kudlula i-1/16 ku-(1.6mm) ubunzulu.
2. Ukungafezeki okubonakalayo, ubukhulu becala, i-crusts, i-seams, i-laps, iinyembezi, okanye izilayi ezingaphantsi kwe-5 yepesenti yobukhulu bodonga.
Ukulungisa isiphene
Xa amabala okanye iziphene zisuswe ngokusila, indawo egudileyo egobileyo iya kugcinwa kwaye ubukhulu bodonga lombhobho abuyi kuba ngaphantsi kwe-87.5% yexabiso elixeliweyo.
Ukulungisa i-welds kwenziwa ngokuhambelana ne-ASTM A530 / A530M.
Ukumakishwa kweThubhu
Umbhobho ngamnye we-ASTM A106 wentsimbi uya kuphawulwa ngokuchongwa komenzi, ibakala lokucaciswa, imilinganiselo, kunye nolwazi lwebakala leShedyuli ukuze kube lula ukuchongwa kunye nokulandeleka.
Uvavanyo lombane lwe-hydrostatic okanye olungonakalisiyo olumakisha le migaqo ilandelayo kufuneka ilandelwe:
