Hollow Chikamu Chimiro
Zvinogona kudarodenderedzwa, mativi mana, rectangular, kana mamwe maumbirwo akakosha.
Ichi chinyorwa chinotarisa pane izvo zvinodikanwa zveASTM A500 zvekutenderera simbi yekugadzira.
Grade Classification
ASTM A500 inoronga simbi pombi kuita mamakisi matatu,giredhi B, giredhi C, uye giredhi D.
Zvakakosha kucherechedza kuti shanduro dzekare dzeASTM A500 dzaivewo neGiredhi A, iyo yakabviswa mune yazvino vhezheni ye2023.
Size Range
Kune machubhu ane dhayamita yekunze ≤ 2235mm [88in] uye ukobvu hwemadziro ≤ 25.4mm [1in].
Raw Materials
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 sesarufa nephosphorus.Inokodzera kukurumidza kugadzirwa kwehuwandu hwakawanda hwesimbi.
Electric Furnace process: Iyo Electric Furnace process inoshandisa yakakwira tembiricha yemagetsi arc kunyungudutsa zvimedu uye nekudzikisa zvakananga simbi, uye inonyanya kubatsira pakugadzira hunyanzvi mamakisi uye kudzora alloy nziyo, pamwe nediki kugadzirwa kwebatch.
Manufacturing Nzira
Seamless kana welding process.
Welded tubing ichagadzirwa kubva simbi-yakatenderedzwa nemagetsi-resistance-welding (ERW) process.Iyo weld seam inofanira kusungirirwa kuti ive nechokwadi chekusimba kwepombi.
Mapombi anogadzirwa newelding process kazhinji haana weld yemukati inobviswa.
Tube End Type
Kana zvisinganyanyi kudiwa, machubhu ekuumbwa anofanira kunge ariflat-enduye kuchena kweburrs.
Kupisa Kurapa
Grade B uye Grade C
Inogona kuderedzwa kana kuderedzwa-kunetseka.
Anealing inopedzwa nekudziisa chubhu kusvika pakupisa kwepamusoro uye wozoitonhodza zvishoma nezvishoma.Annealing inorongazve iyo microstructure yezvinhu kuti ivandudze kusimba kwayo uye kufanana.
Kubvisa kushushikana kunowanzoitwa nekudziisa tembiricha yakadzikira (kazhinji yakadzikira pane yekuvhara) wozoibata kwenguva yakati rebei woitonhodza.Izvi zvinobatsira kudzivirira kukanganisa kana kuputika kwezvinhu panguva yekushanda kunotevera senge welding kana kucheka.

Kureba Kwemuenzaniso: Hurefu hwemuenzaniso unoshandiswa pakuedza hausi pasi pe2 1/2 mukati (65 mm).
Ductility test: Pasina kutsemuka kana kutsemuka, mufananidzo wacho wakatsetseka pakati pemahwendefa anoenderana kusvika chinhambwe chiri pakati pemahwendefa chiri pasi peiyo "H" kukosha yakaverengerwa neinotevera fomula:
H=(1+e)t/(e+t/D)
H = chinhambwe pakati pemapureti ekufuratira, mukati [mm],
e= deformation paurefu hweyuniti (nguva dzose kune yakapihwa giredhi resimbi, 0.07 yeGiredhi B, uye 0.06 yeGiredhi C),
t= yakatsanangurwa kukora kwemadziro echubhu, mukati [mm],
D = yakatsanangurwa kunze kwedhayamita yetubhing, in. [mm].
Kupereratest: Ramba uchidzikamisa mufananidzo kusvikira muenzaniso waputsika kana kuti madziro akapesana emuenzaniso asangana.
Kukundikanacriteria: Laminar peeling kana isina simba zvinhu zvinowanikwa mukati meyedzo yekutsvedza ichave chikonzero chekurambwa.
