Kev siv cov yeeb nkab cap yog tib yam li lub hau, tab sis lub taub hau yeeb nkab feem ntau yog hais txog GB / 25198 - 2010 tus qauv, thaum nyob rau hauv lub teb chaws tus qauv ntawm GB / t{ welded yeeb nkab fittings {1}}, tsis muaj hais txog ntawm cov yeeb nkab taub hau nyob rau hauv ib lo lus, tsuas yog lo lus yeeb nkab cap tshwm, Tsis tsuas yog nyob rau hauv GB / t 12459 - 2017, tab sis kuj nyob rau hauv GB / t 13401 - 2017. Ib lo lus uas tsis hais txog lub taub hau kaw txhais tau hais tias nyob rau hauv lub steel pob tw welded seamless yeeb nkab fittings txheem nws yog hais tias yeeb nkab cap. Cov specifications tsis loj, qhov loj tshaj plaws sab nraud txoj kab uas hla GB / t 12459 - 2017 Φ 813 thiab Φ Los ntawm specification 820. Ntawd yog, qhov loj tshaj ntawm GB / t 13401 - 2017 cov qauv nrog cov specifications loj yog Φ Cov khoom ntawm 1220 yog npaj txhij. Yog tias koj xav nrhiav lub hau npog loj dua, koj yuav tsum tshawb xyuas tus qauv GB / t 25198 - 2010 phau ntawv, uas tuaj yeem pom hauv nws. Φ 6000, uas yog, cov khoom nrog txoj kab uas hla dn6000. Cov ntaub ntawv ntawm ntau lub taub hau hauv tus qauv kuj tseem ceeb heev. Piv txwv li, lub elliptical lub taub hau code lub npe ehb hais txog lub puab kab uas hla, lub eha code lub npe yog hais txog lub sab nraud txoj kab uas hla, los yog spherical taub hau, disk taub hau, spherical crown taub hau, conical plhaub taub hau thiab lub taub hau tiaj tus yog sau nyob rau hauv kom meej heev. .
Tube cap, tseem hu ua cap, cap, thiab lwm yam, yog ib qho haum welded rau lub raj kawg los yog ntsia rau ntawm cov xov sab nraud ntawm lub raj kawg kom npog lub raj thiab kaw lub raj. Lub caliber ntawm cov nom lub kaus mom feem ntau yog tsawg dua dn300, uas yog siv nyob rau hauv lub raj xa dej, uas yog txuas nrog lub raj xa dej los yog ntxiv dag zog rau cov phaj thaiv, thiab tsis yog siv los ua lub ntsiab lus tseem ceeb. Cov khoom siv hauv lub raj yog: carbon steel: (20, a3, q235a, q235b, 20g, 16min, ASTM a234wpb, ASTM a105, thiab lwm yam); Stainless hlau: (304, 304L, 316, 316L, S30408, S30403, S31608, S31603, nws 304, ASTM A403, TP321, 0CR18NI9, {23}} Cr19NI1010Cr.12e, cap. : dn15 - dn800 phab ntsa thickness: sch10 - sch160 tus qauv: asmeb16.9, GB/t12459 - 2017, thiab lwm yam.
Lub taub hau yog lub hau kawg ntawm lub nkoj siab thiab yog lub ntsiab lus tseem ceeb ntawm cov hlab ntsha siab. Daim ntawv yog lub foob. Ib qho yog ua rau sab saum toj thiab hauv qab ntawm cov hlab ntsha siab nyob rau hauv cov duab ntawm lub tank, thiab lwm yam yog tias cov yeeb nkab yog nyob rau sab saum toj thiab hauv qab, thiab nws tsis tau npaj kom ntev mus rau pem hauv ntej, yog li nws sealing cov yeeb nkab hauv cov duab. ntawm lub tank. weld nrog lub taub hau fastener. Raws li cov duab geometric sib txawv, nws tuaj yeem muab faib ua kheej kheej, oval, disc-puab, kheej kheej-crown-puab, conical plhaub thiab tiaj tus, ntawm cov uas kheej kheej, oval, disc-puab thiab spherical-crown-puab lub taub hau kuj muaj. collectively hu ua convex hau. Nws yog siv nyob rau hauv ntau yam khoom ntim xws li cia tank, tshav kub exchangers, yees, reactors, boilers, thiab cov khoom sib cais.
Lub taub hau siv tus qauv: GB / 25198 - 2010
Lub npe ntawm lub taub hau, lub npe code ntawm hom yog raws li nram no:
1. Hemisphere-shaped taub hau: Hom code: hha;
2. oval taub hau: 1) hom code npe: eha; 2) Hom code: ehb;
3. disk taub hau: 1) hom code npe: tha; 2) hom codename: thb;
4. crown-puab lub taub hau: Hom code: sdh;
5. Zoo li lub taub hau ntawm lub tiaj tiaj hauv qab: Hom code: fha;
6. conical taub hau: 1) Hom code: Cha (30); 2) Hom code: Cha (45); 3) Hom code: Cha (60)
Cov ntsiab lus ntawm qhov sib txawv ntawm lub kaus mom thiab lub hau: lub hau thiab lub kaus mom lub kaus mom zoo nkaus li zoo sib xws, thiab qhov sib txawv ntawm ob qhov lus dag feem ntau nyob rau hauv qhov loj ntawm sab hauv txoj kab uas hla thiab qhov kev siv. Yav dhau los, nws kuj tau hais tias cov yeeb nkab cap tsuas yog ntsaws ntawm cov yeeb nkab, uas feem ntau tsis tshaj dn300. yog tias qhov loj dua, lub thwj yuav tsum tau siv. taub qab weld foob txoj kev xav tuaj yeem ua tsis tiav. cov cuab yeej txwv feem ntau yog hais txog dn6000.
