Ishubhu yensimbi ye-ASTM A210 iyishubhu yensimbi engenamthungo ekhabhoni esetshenziswa njengobhayela kanye namashubhu okushisa aphezulu okushisa okuphezulu nendawo enengcindezi ephezulu, njengaseziteshini zikagesi namabhayela ezimboni.

Ububanzi bangaphandle: 1/2ku(12.7mm)≤ OD ≤5in (127mm)
Ukuqina Kwezindonga: 0.035 kokungu-(0.9mm)≤ WT ≤0.500 kokungu-(12.7mm)
Amashubhu anobunye ubukhulu angase anikezwe, inqobo nje uma lawo mashubhu ethobela zonke ezinye izimfuneko zalokhu kucaciswa.
Ama-Raw material
Ukuzijwayeza ukwenza insimbi--Insimbi izobulawa.
insimbi ebulewe ibhekisela ekwengezweni kwamanani athile ama-deoxidizers njenge-silicon, i-aluminium, ne-manganese phakathi nenqubo yokuncibilika kwensimbi.
Lezi zithako zingasabela nge-oksijini esensimbini ukuze kukhiqizwe ama-oxide aqinile, ngaleyo ndlela kunciphise okuqukethwe komoyampilo ensimbi futhi kuvimbele ukwakheka kwe-oxidizing inclusions.
Ibanga le-ASTM A210
I-ASTM A210 itholakala ngamabanga amabili:IBanga A-1 kanye neBanga C.
I-ASTM A210 Inqubo Yokukhiqiza Ishubhu Lensimbi engenamthungo
Amapayipi ensimbi azokwenziwa ngenqubo engenamthungo futhi azobakushisa-kuqedile or kuyabandanjengoba kucacisiwe.
Ngokuvamile, amapayipi ensimbi anobubanzi obungaphezu kwamamilimitha angu-30 ayashiswa futhi lawo anobubanzi obungaphansi noma obulingana namamilimitha angu-30 aqedwa ngokubanda.Le ndlela yokuhlukanisa ayiphelele kodwa ingasetshenziswa njengendlela esheshayo nelula yokunquma indlela yokucubungula yepayipi lensimbi engenamthungo.
Ukwelashwa Kokushisa
Ukwelashwa kokushisa akudingekile kumashubhu aphelile ashisayo.
Amashubhu aqedwe ngokubanda azonikezwa i-aneal subcritical, i-aneal egcwele, noma ukwelashwa okushisa okujwayelekile ngemva kwenqubo yokugcina yokubanda.
Izingxenye Zekhemikhali

Lezi zidingo zokwakheka kwamakhemikhali ziqinisekisa ukuthi amashubhu anamandla anele nokumelana nezinga lokushisa.
Izakhiwo Zemishini
Izidingo zezakhiwo zikamshini azisebenzi kumashubhu amancane kune1/ 8ku- [3.2 mm] ububanzi bangaphakathi noma 0,015 in. [0.4 mm] ngogqinsi.

| ABheka Ithebula 4 ukuze uthole amanani aphansi okubaliwe. | ||||
Ithebula lesi-4 linikeza amanani amancane okubaliwe ama-elongation ngayinye1/32ngaphakathi. [0.8 mm] ukuncipha kokujiya kodonga.
Lapho ubukhulu bodonga buphakathi kwamanani amabili aboniswe ngenhla, ubuncane bevelu yobude buzonqunywa isibalo esilandelayo:
Amayunithi we-Imperial(in): E = 48t+15.00
Iyunithi ye-SI(mm): E = 1.87t+15.00
kuphi:
E = ubude ku-2 in. noma 50 mm, %,
t = ukujiya kwangempela kwesampula.
Ukuhlolwa kokuqina
Ukuhlolwa kokuqina kwe-Brinell noma kwe-Rockwell kuzokwenziwa kuma-specimens asuka kumashubhu amabili asuka endaweni ngayinye.
I-ASTM A210 Ibanga A-1:79-143 HBW
I-ASTM A210 IBanga C: 89-179 HBW
I-HBW ibhekisela esilinganisweni se-Brinell Hardness, lapho u-"W" emele ukusetshenziswa kwebhola le-carbide njenge-indenter.
Okunye Ukuhlola
Ukuhlola Ukucaba
Ukuhlolwa kwe-Flaring
I-Hydrostatic noma i-Nondestructive Electric Test
Surface Finishing
Ingafakwa emanzini anosawoti noma iqhunyiswe, noma kokubili, futhi le ngxenye iyindaba yesivumelwano, futhi ukukhetha kusekelwe esivumelwaneni phakathi komsebenzisi nomenzi.
I-Pickling isetshenziselwa kakhulu ukususa izingqimba ezine-oxidized nokunye ukungcola ebusweni bamapayipi ensimbi.
I-shot blasting isetshenziselwa ukuhlanza indawo futhi ithuthukise amandla ayo okunamathela.
Lezi zindlela zokwelapha azithinti nje kuphela ikhwalithi engaphezulu yepayipi kodwa zingase futhi zithinte izakhiwo zayo zokugcina.
Ukwakha Imisebenzi
Uma efakwe kubhayela, amashubhu azoma enwebeka futhi enziwe ubuhlalu ngaphandle kokubonisa imifantu noma amaphutha.Uma esetshenziswe kahle, amashubhu okushisa aphezulu azomela yonke imisebenzi yokubumba, yokushisela, kanye nokugoba edingekile ukuze ifakwe ngaphandle kokuthuthukiswa kokulimala.
Ukumaka kwe-ASTM A210
Okulandelayo kufanele kumakwe ngokucacile:
Igama lomkhiqizi noma ilogo.
Ukucaciswa kwepayipi (usayizi, ubukhulu bodonga, njll.).
Ibanga lamapayipi.
Uhlobo lokukhiqizwa kwepayipi lensimbi: ukushisa okuphelile noma okubandayo kuphelile.
Izicelo ze-ASTM A210
Isetshenziswa ekwenzeni amaboilers amancane kuya kosayizi abamaphakathi anengcindezi encane, njengamaboiler amile, amaboiler ahlala phansi, namanye amaboilers asetshenziselwa ukushisisa izimboni noma zokuhlala.
Ama-Superheaters ayingxenye yebhayela esetshenziselwa ukuphakamisa izinga lokushisa lesitimu ngaphezu kwendawo yokubilisa, futhi amashubhu e-ASTM A210 afanele ukwenziwa kwalezi zingxenye ezishisa kakhulu.
Imikhiqizo Yethu Ehlobene
Singabakhiqizi nabahlinzeki bepayipi lensimbi yensimbi esezingeni eliphezulu abavela eChina, futhi siphinde sibe nesitoko sepayipi sensimbi esingenamthungo, sikunikeza izixazululo eziningi zamapayipi ensimbi!
