Ib, cim rau ntawm lub cev yeeb nkab
Kev txheeb xyuas ua ntej ntawm GB Standard thiab Tsis yog -Cov kav hlau kav hlau kav ntawm cov yeeb nkab cim
GB-tus qauv K9 cov kav dej hlau yog tsim los nruj raws li GB/T 13295. Cov cim meej meej thiab ua tiav yog muaj nyob rau ntawm cov yeeb nkab lub cev, nrog rau kev siv tus qauv GB/T 13295, K9 qib, nominal txoj kab uas hla, chaw tsim khoom, hnub tsim khoom thiab tiv thaiv - cov cim corrosion. Cov cim yog ruaj thiab ruaj khov.
Feem ntau tsis yog{0}} cov kav dej txheem muaj cov cim tsis tiav. Lawv tsis muaj tus lej qauv hauv tebchaws thiab qib K9. Cov ntawv luam tawm yog ntxhib thiab yooj yim tev tawm. Cov ntaub ntawv tsis tiav ua rau traceability ua tsis tau.
Cov cim tsuas yog siv tau rau kev tshuaj ntsuam ua ntej. Phab ntsa thickness ntsuas yog ib qho yuav tsum tau ua pov thawj ua ntej kev yuav khoom thiab xa mus rau qhov chaw tsim kho.
2, Phab ntsa Thickness thiab Nyhav
Qhov sib txawv ntawm GB Standard thiab Tsis yog -Cov kav hlau kav hlau: Phab ntsa Thickness thiab Qhov hnyav
GB-tus qauv K9 cov kav dej hlau txais yuav cov phab ntsa nominal thickness xam raws li cov qauv qhia hauv GB/T 13295. Qhov tsawg kawg nkaus phab ntsa tuab yog tswj, thiab qhov hnyav ib 'meter' raws li tus qauv theoretical tus nqi. Cov kav dej muaj cov phab ntsa tuab tuab nrog lub siab ruaj khov thiab tiv thaiv - kev daws teeb meem.
Feem ntau cov tsis yog - cov kav dej txheem yog tsim los ntawm txhob txwm tshaj tawm cov yeeb nkab phab ntsa. Lawv cov phab ntsa tiag tiag yog qis dua qhov tsawg kawg nkaus hauv lub tebchaws tus qauv, thiab tag nrho cov yeeb nkab hnyav yog sib dua. Qee cov tuam txhab lag luam cuav kos npe rau qib K9, thaum ntsuas phab ntsa tuab thiab qhov hnyav tsis ua raws li qhov yuav tsum tau ua.
3, Kev ua haujlwm sab hauv
Qhov sib txawv ntawm Kev Ua Haujlwm Sab Hauv Nruab Nrab ntawm GB Standard thiab Tsis yog -Cov kav dej Standard
GB-tus qauv K9 cov kav hlau kav yog ua los ntawm cov khoom siv ruaj khov. Tus nqi spheroidization, elongation thiab tensile lub zog tag nrho ua tau raws li qhov yuav tsum tau muaj ntawm GB / T 13295. Cov kav dej muaj qhov zoo heev toughness, muaj zog cuam tshuam thiab tsis kam rau lub hauv paus kev daws teeb meem, thiab tsis ua rau nkig rupture nrog siab ntev - lub sij hawm ua hauj lwm kev nyab xeeb.
Cov kav dej uas tsis yog -tus qauv siv cov khoom siv tsis zoo sib xws nrog cov graphite spheroidization tsis zoo thiab tsis txaus elongation, ua rau cov khoom tawg. Kev tawg lossis cov yeeb nkab tawg yuav tshwm sim nyob rau hauv qhov tsis sib xws hauv lub hauv paus kev daws teeb meem lossis kev quab yuam sab nraud, ua rau muaj kev pheej hmoo siab ntawm kev xau thaum lub sijhawm ua haujlwm ntev -.
4, Cov ntsiab lus
Hauv cov ntsiab lus, qhov sib txawv ntawm GB- tus qauv thiab tsis yog - cov kav hlau kav hlau tsis yog tsuas yog nyob rau hauv qhov tsos thiab qhov hnyav, tab sis ua tiav hauv cov qauv tsim khoom, cov khoom siv thiab kev nyab xeeb ntawm kev ua haujlwm.
GB- cov kav dej txheem nruj nruj raws li GB/T 13295, muaj cov cim cim, tsim nyog phab ntsa tuab thiab qhov hnyav, zoo heev toughness, ruaj khov siab tsis kam thiab kev sib haum xeeb. Nrog rau kev ua haujlwm ntev thiab kev nyab xeeb siab, lawv muaj feem xyuam rau cov dej hauv nroog, cov dej ntws thiab cov dej num tseem ceeb.
Tsis yog- cov kav dej txheem yog tsim los nrog txo cov phab ntsa tuab, cov ntaub ntawv txo qis thiab yooj yim los tiv thaiv- kev kho corrosion. Txawm hais tias tus nqi qis, lawv ua tsis tau raws li cov qauv kev ua tau zoo thiab ua rau muaj kev pheej hmoo loj ntawm kev xau, tawg thiab cov yeeb nkab tawg. Lawv tsuas yog tsim nyog rau cov xwm txheej yooj yim ib ntus thiab txwv nruj rau cov dej siab thiab cov dej num tseem ceeb. Kev siv cov kav dej tus qauv zoo tuaj yeem zam kev txij nkawm tom qab thiab rov ua haujlwm dua.
Shanxi Jintai Hongye Casting thiab Forging Machinery Co., Ltd., nyob rau hauv Shanxi Xeev, Tuam Tshoj, yog ib tug ua chaw tsim tshuaj paus ntawm ductile hlau yeeb fittings, kav, ntau yam li qub, thiab manhole npog. Peb muaj automated ntau lawm kab thiab ib tug kev paub ntau lawm technology pab neeg los muab koj nrog kev thiab hloov tau customized daws.
