Cov Khoom Qhia Txog Khoom

Cov Cim Npe Khoom

ASTM A179/ASME SA179 yog dab tsi?

ASTM A179 (ASME SA179) yog cov raj hlau tsis muaj pa roj carbon tsawg uas siv rau hauv cov khoom siv hloov cua sov tubular, condensers, thiab cov ntawv thov hloov cua sov zoo sib xws.

ASTM A179 thiab ASME SA179 yog ob tus qauv uas sib npaug kiag li. Rau qhov yooj yim, ASTM A179 siv hauv qab no.

Qhov Ntev Ntau Yam

ASTM A179 yog tsim rau cov kav hlau uas muaj txoj kab uas hla sab nraud ntawm 1/8″ - 3″ [3.2mm - 76.2mm].

Botop Hlauyog tus muag khoom yeeb nkab hlau tsis muaj seamless los ntawm Tuam Tshoj, muab rau koj xaiv ntau yam zoo ASTM A179 / ASME SA179 cov yeeb nkab hlau tsis muaj seamless txias.

Peb mob siab rau muab peb cov neeg siv khoom nrog cov khoom lag luam zoo tshaj plaws thiab cov kev pabcuam kom ntseeg tau tias koj cov haujlwm khiav mus zoo. Xaiv Botop Steel, thiab xaiv tus khub txhim khu kev qha.

Cov Txheej Txheem Tsim Khoom

Peb twb tau hais lawm tias A179 yog tsim los ntawm kev siv cov txheej txheem tsim khoom txias-drawn seamless. Cov txheej txheem tshwj xeeb twg koom nrog kev tsim khoom txias-drawn seamless? Thov saib daim ntawv qhia cov txheej txheem hauv qab no.

Cov txheej txheem tsim cov yeeb nkab hlau tsis muaj qhov txias

Hauv ASTM tus qauv,A556kuj siv cov txheej txheem tsim khoom txias-duab seamless tab sis yog tshwj xeeb rau cov cua sov dej tubular. Cov neeg uas xav paub ntxiv tuaj yeem nrhiav paub ntxiv.

Kev Kho Mob Kub

Tom qab kos duab txias kawg, cov kav hlau raug kho cua sov ntawm qhov kub ntawm 1200 ° F [650 ° C] lossis siab dua.

ASTM A179 tsis pub ntxiv lwm yam khoom rau hauv cov tshuaj lom neeg.

ASTM A179 Qhov Nyuaj

Qhov nyuaj ntawm cov yeeb nkab hlau yuav tsum tsis pub tshaj 72 HRBW (Rockwell hardness).

Kev Ntsuas Hydrostatic

Txhua lub yeeb nkab yuav tsum raug kuaj xyuas hydraulic lossis, yog tias tus neeg yuav khoom tau teev tseg, kev kuaj hluav taws xob uas tsis ua puas tsuaj yuav siv tau hloov chaw.

Lub raj hlau tswj tau qhov siab rau tsawg kawg 5s yam tsis muaj qhov xau.

Qhov kev sim siab yog xam los ntawm kev siv cov qauv hauv qab no:

Nti - Phaus Chav: P = 32000 t/D

Chav SI: P = 220.6t/D

P = hydrostatic test pressure, psi lossis MPa;

t = teev tseg phab ntsa tuab, hauv. lossis hli;

D = teev tseg sab nraud txoj kab uas hla, hauv. lossis mm.
