Iyi pombi inonyanya kushandiswa kumakanika uye kudzvanywa maapplications asi yakakodzerawo kushandiswa seyakajairika pombi yekufambisa chiutsi, mvura, gasi, uye mweya.
Saizi yemhando yeASYM A53 iri DN 6-650.
Mhando yekugadzira yeRudzi E nderinoti DN 20-650 DN.
Madhayamita epombi ari pasi peDN 20 idiki kuRudzi E. Nezvikonzero zvehunyanzvi hapana nzira yekuagadzira, saka Type S, inovanzira yekugadzira isina musono, inowanzoshandiswa.
Kugadzira Maitiro eASTM A53 Type E
Maitiro ekugadzira anosanganisira kugadzira simbi coils kuburikidza nema rolls, welding edges nekudziisa kupisa, deburring welds, uye saizi uye kutwasanudza kugadzira machubhu.

Cherechedza A: Hurefu hwehurefu mu2 mu[50 mm] huchave hwakatemwa neinotevera equation:
e = 625000 [1940] A0.2/U0.9
e = kureba kwakaderera mu2 mukati kana 50 mm muzana, yakatenderedzwa kusvika muzana iri pedyo
A = idiki ye0.75 mukati2[500 mm2] uye nzvimbo yakachinjika yechiratidzo chetension test, yakaverengerwa pachishandiswa dhayamita yekunze yepombi, kana hupamhi hwezita rechiratidzo chetension test uye ukobvu hwemadziro hwakatsanangurwa hwepombi, ine kukosha kwakaverengerwa kwakatenderedzwa kune iri pedyo 0.01 mu2 [1 mm2].
U=yakatarwa simba shoma rekusimba, psi [MPa].
Cherechedza B: Ona Tafura X4.1 kana Tafura X4.2, chero ipi inoshanda, pahushoma hwehurefu hwekurebesa hunodiwa pamisanganiswa yakasiyana-siyana yetension test specimen size uye yakataurwa shoma yekusimba simba.
Bend Test
Papombi, DN ≤50, hurefu hwakakwana hwepombi huchakwanisa kukotamiswa ichitonhora kuburikidza ne90 ° kutenderedza cylindrical mandrel, iyo dhayamita yakapetwa kagumi nembiri pane yakataurwa kunze kwedhayamita yepombi, pasina kugadzira mitswe pane chero chikamu uye pasina. kuvhura weld.
Kaviri-yakawedzera-yakasimba pombi pamusoro peDN 32 haidi kuiswa pasi pekuyedzwa kwekubhenda.
"Double-extra-strong", inowanzonzi XXSipombi ine mudhuri wakasimbiswa zvakanyanya, inowanzoshandiswa mumaindasitiri ekushandisa kutsungirira kudzvinyirirwa kwepamusoro uye nharaunda dzakaomarara.Ukobvu hwemadziro epombi iyi yakanyanya kukora kupfuura pombi yakajairika, saka inopa simba rakawanda uye kusimba kuri nani.
Flattening Test
Muedzo wekubata kumeso uchaitwa papombi yakasungwa pamusoro peDN 50 muhuremu hwakasimba (XS) kana kureruka.
Iyi inotevera nzira yekuyedza inoshanda kune Type E, Magiredhi A uye B.
Munguva yekutsikirira yakatsetseka, iyo weld inofanirwa kuiswa pa 0 ° kana 90 ° kune mutsara wekutungamira kwesimba, zvichienderana nezvinodiwa chaizvo.
Danho 1: Edzai ductility ye weld.Panofanira kunge pasina kuputika kana kuputsika mukati memukati kana kunze kwekunze kwe weld kusvikira chinhambwe pakati pemahwendefa akafuratira chiri pasi pezvikamu zviviri kubva muzvitatu zvekunze kwepaipi.
Danho rechipiri: Ramba uchidzvanya flat uye kuyedza ye ductility munzvimbo iri kunze kwe weld.Panofanira kunge pasina kutsemuka kana kutsemuka mukati kana kunze kwepombi kunze kweiyo weld kusvika chinhambwe chiri pakati pemafurati ari pasi pechikamu chimwe chete muzvitatu chedhayamita yekunze kwepombi, asi kwete pasi pekashanu ukobvu hwepombi. pombi wall.
Danho rechitatu: Edzai kutendeseka kwechinhu nekuenderera mberi nekudzvanya pasi kusvika bvunzo dzemuenzaniso dzaputsika kana madziro epombi asangana.Izvi zvinoshandiswa kuyedza zvinhu zvematambudziko akadai seakatsemuka maseru, kusasimba, kana asina kukwana welds.
Hydrostatic Test
Iyo hydrostatic bvunzo ichaiswa, pasina kuvuza kuburikidza nemusono we weld kana muviri wepombi.
Plain-end pombi ichayedzwa hydrostatically kune iyo inoshanda yakapihwa muTable X2.2,
pombi yakarukwa-uye-yakabatana ichaongororwa hydrostatically kune kumanikidzwa kunoshanda kwakapihwa muTebhu X2.3.
Kune mapaipi esimbi ane DN ≤ 80, kudzvanywa kwekuyedza hakufaniri kudarika 17.2MPa;
Pamapombi esimbi ane DN＞80, kudzvanywa kwebvunzo hakufanire kudarika 19.3MPa;
Nondestructive Electric Test
Kune Type E uye Type F Kirasi B mapaipi DN ≥ 50, ma welds anofanirwa kuisirwa kuongororwa kusingaparadze magetsi.
Kuongororwa kwemagetsi kusingaparadzi kuchaitwa zvinoenderana neSpecifications E213, E273, E309 kana E570.
Kana kuyedza kusingaparadze magetsi kwaitwa, pombi ichaiswa chiratidzo "NDE".
