Diameter yo hanze: 1/2muri (12.7mm) ≤ OD ≤5in (127mm)
Uburebure bw'urukuta: 0.035 muri (0.9mm) ≤ WT ≤0.500 muri (12.7mm)
Igituba gifite ibindi bipimo birashobora gutangwa, mugihe utu tubari twujuje ibindi bisabwa byose.
Ibikoresho bito
Imyitozo yo gukora ibyuma--Icyuma kizicwa.
ibyuma byiciwe bivuga kongeramo umubare munini wa deoxidizeri nka silicon, aluminium, na manganese mugihe cyo gushonga ibyuma.
Izi nyongeramusaruro zirashobora kwitwara hamwe na ogisijeni mubyuma kugirango bitange okiside ikomeye, bityo bigabanye umwuka wa ogisijeni mubyuma kandi bikabuza gushiraho okiside.
ASTM A210 Icyiciro
ASTM A210 iraboneka mubyiciro bibiri:Icyiciro A-1 na C..
ASTM A210 Uburyo bwo gukora ibyuma bitagira ibyuma
Imiyoboro yicyuma igomba gukorwa nuburyo butagira ikizinga kandi igombaBishyushye or ubukonje-bwuzuyenkuko byasobanuwe.
Mubisanzwe, imiyoboro yicyuma ifite diameter irenga milimetero 30 zirashyushye kandi izifite diameter iri munsi ya milimetero 30 zirangiye ubukonje.Ubu buryo bwo gutandukanya ntabwo bwuzuye ariko burashobora gukoreshwa nkuburyo bwihuse kandi bworoshye bwo kumenya uburyo bwo gutunganya imiyoboro idafite ibyuma.
Kuvura Ubushuhe
Kuvura ubushyuhe ntabwo bisabwa kubituba bishyushye.
Imiyoboro ikonje ikonje igomba guhabwa anneal subcritical anneal, anneal yuzuye, cyangwa kuvura ubushuhe busanzwe nyuma yuburyo bwa nyuma bwo kurangiza ubukonje.

Ibi bisabwa bigize imiti byemeza ko imiyoboro ifite imbaraga zihagije hamwe nubushyuhe bwubushyuhe.
Ibikoresho bya mashini
Ibikoresho bya mashini bisabwa ntabwo bikurikizwa kuri tubing ntoya1/ 8muri [3,2 mm] imbere ya diameter cyangwa 0,015 muri. [0.4 mm] mubyimbye.

Iyo uburebure bwurukuta buri hagati yindangagaciro ebyiri zerekanwe hejuru, agaciro ntarengwa ko kuramba kugenwa nuburinganire bukurikira:
Ibice by'ibwami (muri): E = 48t + 15.00
Igice cya SI (mm): E = 1.87t + 15.00
aho:
E = kurambura muri 2 muri. Cyangwa 50 mm,%,
t = ubunini nyabwo bwikigereranyo.
Ikizamini gikomeye
Ibizamini bya Brinell cyangwa Rockwell bizakorwa kubigereranyo biva mu tubari tubiri kuri buri gice.
ASTM A210 Icyiciro A-1: 79-143 HBW
ASTM A210 Icyiciro C: 89-179 HBW
HBW bivuga gupima ubukana bwa Brinell, aho "W" igereranya gukoresha umupira wa karbide nka indenter.
Ubundi bushakashatsi
Ikizamini cya Flattening
Ikizamini cyo gutwika
Ikizamini cyamashanyarazi ya Hydrostatike cyangwa idafite ingufu
Kurangiza Ubuso
Irashobora gutororwa cyangwa guturika, cyangwa byombi, kandi iki gice nikibazo cyubwumvikane, kandi guhitamo gushingiye kumasezerano hagati yumukoresha nuwabikoze.
Gutoragura bikoreshwa cyane mugukuraho ibice bya okiside hamwe nibindi byanduza hejuru yimiyoboro yicyuma.
Kurasa kurasa bikoreshwa mugusukura hejuru no kongera imbaraga zifatika.
Ubu buryo bwo kuvura ntibuhindura gusa ubwiza bwubuso bwumuyoboro ahubwo bushobora no kugira ingaruka kumikorere yanyuma.
Gushiraho Ibikorwa
Iyo byinjijwe muri boiler, tebes igomba guhagarara kwaguka no kwerekanwa iterekanye ibice cyangwa inenge.Iyo ikoreshejwe neza, imiyoboro ya superheater igomba guhagarara ibikorwa byose byo guhimba, gusudira, no kugonda bikenewe mugukoresha udatezimbere inenge.
ASTM A210 Ikimenyetso
Ibikurikira bigomba gushyirwaho ikimenyetso:
Izina ryumukoresha cyangwa ikirango.
Ibisobanuro by'umuyoboro (ubunini, uburebure bw'urukuta, n'ibindi).
Icyiciro cy'umuyoboro.
Ubwoko bw'umusaruro w'icyuma: ubushyuhe burangiye cyangwa ubukonje bwarangiye.
Porogaramu ya ASTM A210
Ikoreshwa mugukora amashyiga mato mato mato mato yumuvuduko ukabije, nka bisi ihagarara, ibyuma byicara, hamwe nandi mavuta akoreshwa mubushuhe bwinganda cyangwa gutura.
Ibihe bya superheater ni ibice byicyuma gikoreshwa mukuzamura ubushyuhe bwamazi hejuru yacyo, kandi imiyoboro ya ASTM A210 irakwiriye gukora ibyo bice byubushyuhe bwo hejuru.
Ibicuruzwa Bifitanye isano
Turi abanyabugeni bo mu rwego rwo hejuru basudira ibyuma bya karuboni kandi bitanga ibicuruzwa biva mu Bushinwa, kandi tunabika ibyuma bidafite ibyuma, biguha ibisubizo byinshi byicyuma!
