ASTM A500 inotonhora-yakagadzirwa welded uye isina musono kabhoni simbi yekumisikidza tubing yewelded, riveted, kana bolted mabhiriji uye zvivakwa zvekuvaka uye zvakajairwa zvimiro zvinangwa.
Giredhi Bichubhu yesimbi ine simba regoho risingasviki 315 MPa [46,000 psi] uye simba rekusimba risingasviki 400 MPa [58,000], rinoshandiswa mumhando dzakasiyana siyana dzekuvaka. uye mapurojekiti emuchina nekuda kwekugadzikana kwayo kwemaitiro uye kusimba.
ASTM A500 inoronga simbi pombi kuita mamakisi matatu,giredhi B,giredhi C, uye giredhi D.
Yemachubhu anekunze dhayamita ≤ 2235mm [88in]uyekukora kwemadziro ≤ 25.4mm [1in].
Zvisinei, kana ERW welding process ikashandiswa, mapaipi chete ane hupamhi hwehupamhi hwe 660 mm uye kukora kwemadziro e20 mm kunogona kuitwa.
Kana iwe uchida kutenga pombi ine yakakura dhayamita madziro ukobvu, unogona kusarudza kushandisa iyo SAW welding process.
CHS: Zvikamu zvedenderedzwa.
RHS: Sikweya kana rectangular hollow zvikamu.
EHS: Elliptical hollow zvikamu.
Simbi ichagadzirwa neimwe kana kupfuura yeanotevera maitiro:okisijeni yakakosha kana choto chemagetsi.
Basic Oxygen Process: Iyi inzira yemazuva ano inokurumidza kugadzira simbi, iyo inoderedza kabhoni yemukati nekufuridza okisijeni musimbi yenguruve yakanyungudutswa ichibvisa zvimwe zvisingadiwe zvakaita sesarufa nephosphorus.Inokodzera kukurumidza kugadzirwa kwehuwandu hwakawanda hwesimbi.
Electric Furnace process: Iyo Electric Furnace process inoshandisa yakakwira-tembiricha yemagetsi arc kunyungudutsa zvimedu uye yakananga kuderedza simbi, uye inonyanya kubatsira mukugadzira magiredhi ehunyanzvi uye kudzora alloy nziyo, pamwe nekugadzira batch diki.
Machubhu achagadzirwa neelectric-resistance-welded (ERW)process.
ERW pombi magadzirirwo ekugadzira weld nekukochekera zvinhu zvesimbi kuita humburumbira uye kuisa kuramba uye kumanikidza pakureba kwayo.
Giredhi B tubing inogona kuderedzwa kana kudzoreredzwa-kunetseka.
Iyo kemikari inoumbwa yeASTM A500 Giredhi B simbi inosanganisira ine mwero huwandu hwekabhoni uye manganese kuve nechokwadi chakanaka chemuchina zvivakwa uye weldability.Panguva imwecheteyo, phosphorus nesarufa mazinga anodzorwa zvakasimba kuti adzivise embrittlement, uye ine mwero yekuwedzera yemhangura inovandudza corrosion resistance.
Izvi zvivakwa zvakakodzerwa nemaitiro ekushandisa, kunyanya munzvimbo dzinodiwa kunaka weldability uye kusimba.
Mienzaniso inosangana nezvinodiwa zveASTM A370, Appendix A2.

Weldductilitytest: Uchishandisa sampuli inokwana masendimita mana (100 mm) kureba, gadzirisa mufananidzo ne weld pa 90 ° kusvika kune nzira yekuisa kusvikira chinhambwe pakati pemahwendefa chiri pasi pe 2/3 yekunze kwepaipi.mufananidzo wacho haufanirwe kuputika kana kuputsika mukati kana kunze kwekunze panguva iyi.
Pipe ductility test: ramba uchigadzirisa muenzaniso kusvikira chinhambwe pakati pemahwendefa chiri pasi pe 1/2 yepombi yekunze dhayamita.panguva ino, pombi haifaniri kuva nekuputika kana kuputsika mukati uye kunze kwekunze.
Kupereratest: Ramba uchidzikamisa sampuli kusvika kutyoka kwaitika kana kusvika izvo zvinodikanwa zvemadziro zvakasangana.Kana humbowo hwekupenengura ply, zvinhu zvisina kugadzikana, kana mawelds asina kukwana akawanikwa panguva yekuyedzwa kwekubata kumeso, mufananidzo wacho unozotongwa usingagutse.
Muedzo wekupisa unowanikwa kune akatenderera machubhu ≤ 254 mm (10 mukati) mudhayamita, asi hazvisungirwe.
Machubhu ose ngaave asina kuremara uye ngaave nemupendero wakaita somushandi.
Kusakwana kwepamusoro kuchaverengerwa sehurema kana kudzika kwadzo kuchidzikisa ukobvu hwemadziro asara kusvika pasi pe90% yehukobvu hwemadziro hwakatsanangurwa.
Kukanganisa kunosvika 33% yehukobvu hwemadziro hwakatsanangurwa hwakadzama hunogona kubviswa zvachose nekucheka kana kugaya kupedzisa simbi.
Kana filler welding ikashandiswa, iyo yakanyorova welding process ichashandiswa uye inobuda weld simbi inobviswa kuti ichengetedze nzvimbo yakatsetseka.
Kuremara kwepamusoro, senge mamaki ekubata, madiki mold kana roll mamaki, kana makomba asina kudzika, haaonekwe seakaremara chero achigona kubviswa mukati mehukobvu hwemadziro.
Mashoko anotevera anofanira kuverengerwa:
Zita remugadziri: Iri rinogona kunge riri zita rizere remugadziri kana chidimbu.
Brand kana Mucherechedzo: Zita rechiratidzo kana chiratidzo chinoshandiswa nemugadziri kusiyanisa zvigadzirwa zvawo.
Specification Designator: ASTM A500, iyo haifaniri kusanganisira gore rekubudiswa.
Tsamba Yegiredhi: B, C kana D giredhi.
Kune machubhu ezvimiro ≤ 100mm (4in) mudhayamita, mavara anogona kushandiswa kumaka ruzivo rwekuzivikanwa zvakajeka.
Inonyanya kushandiswa kune zvimiro zvezvinangwa, inopa inodiwa yemagetsi simba uye weldability kutsigira dhizaini uye kuvaka kwekuvaka uye mainjiniya zvimiro.
Iyi pombi yesimbi inoshandiswa zvakanyanya mukuvaka mapuranga, mabhiriji, zvivako zvemaindasitiri, uye zvakasiyana-siyana zvezvimwe zvikamu zvekugadzirisa zvinoda simba uye kusimba.
