Txais tos rau peb lub blog! Hauv tsab xov xwm hnub no, peb yuav tham txog American Standard ASTM A500 Square Pipe thiab nws qhov tseem ceeb hauv kev lag luam xa khoom hlau. Ua tus thawj coj ASTM A500 tus qauv yeeb nkab steel tsim thiab muab khoom, Shandong Jinbaicheng Metal Materials Co., Ltd. tau cog lus tias yuav muab cov khoom hlau zoo uas ua tau raws li cov qauv thoob ntiaj teb. ASTM A500 square pipe yog ib qho tseem ceeb hauv kev ua lag luam, thiab peb yuav saib tob dua ntawm nws cov qib hlau, tshwj xeeb tshaj yog ASTM A500 Qib A thiab ASTM A500 Qib B. Tsis tas li ntawd, peb yuav tshawb nrhiav qhov zoo ntawm cov yeeb nkab steel txias. Yog li, cia peb pib!
1. Nkag siab txog ASTM A500 cov yeeb nkab plaub fab:
ASTM A500 lub raj xa dej square yog tsim raws li American Society for Testing and Materials (ASTM) A500 tus qauv, uas yog tshwj xeeb rau cov raj xa dej carbon steel uas tau tsim txias thiab tsis muaj qhov sib txuas. Nws lub npe "tubing structural" qhia txog nws daim ntawv thov tseem ceeb hauv ntau yam haujlwm tsim kho xws li tsev, choj thiab lwm yam kev txhawb nqa. Vim yog cov hlau carbon zoo tshaj plaws, lub raj xa dej square no muaj lub zog tshwj xeeb, kev ruaj khov thiab kev ntseeg siab.
2. Cov hlau xa tawm ntawmASTM A500 tus qauvcov kav hlau:
Kev xa tawm hlau ua lub luag haujlwm tseem ceeb hauv kev lag luam thoob ntiaj teb, muab cov khoom siv raw rau cov teb chaws thoob ntiaj teb. Nws txhawb kev loj hlob ntawm kev lag luam thiab kev txhim kho vaj tse. Yuav kom ntseeg tau tias qhov zoo ntawm kev xa tawm hlau, kev ua raws li cov qauv thoob ntiaj teb yog qhov tseem ceeb heev. Tus qauv ASTM A500 lav qhov zoo thiab kev ua tau zoo ntawm cov raj plaub fab, ua rau nws yog thawj qhov kev xaiv rau kev xa tawm hlau. Nrog rau qhov kev thov nce ntxiv rau cov raj zoo, ASTM A500 Square Pipe tau dhau los ua cov khoom tseem ceeb rau cov teb chaws uas tab tom nrhiav kev xa tawm hlau txhim khu kev qha.
3. ASTM A500 Qib A thiab ASTM A500 Qib B:
Raws li American Standard ASTM A500, muaj ob hom hlau tseem ceeb uas siv ntau: ASTM A500 Qib A thiab ASTM A500 Qib B. Cov khoom siv kho tshuab thiab cov lus qhia ntawm cov hlau no sib txawv. ASTM A500 Qib A muab lub zog tsawg kawg nkaus ntawm 46,000 psi (315 MPa), thaum ASTM A500 Qib B muab lub zog tsawg kawg nkaus ntawm 50,000 psi (345 MPa). Lub zog siab dua ntawm Qib B ua kom muaj kev ruaj khov ntawm cov qauv ua rau nws tsim nyog rau cov ntawv thov uas xav tau ntau dua.
4. Qhia txog qhov zoo ntawm cov kav dej hlau txias:
Cov yeeb nkab hlau uas rub txias yog lub npe hu ua nws qhov tiav zoo kawg nkaus thiab qhov loj me. Cov txheej txheem tsim khoom suav nrog kev rub cov yeeb nkab hlau kub dov los ntawm lub pwm, uas ua rau cov khoom tiav du thiab meej dua. Cov txheej txheem no ua rau cov khoom siv kho tshuab ntawm cov yeeb nkab zoo dua, suav nrog kev muaj zog ntxiv, qhov nyuaj thiab kev tiv thaiv xeb. Cov yeeb nkab hlau uas rub txias yog siv dav hauv kev lag luam xws li tsheb, kev tsim kho thiab tshuab uas qhov zoo tshaj plaws thiab qhov loj me yog qhov tseem ceeb.
5. Yuav ua li cas xaiv tus neeg muab khoom siv ASTM A500 steel yeeb nkab?
Ntawm Shandong Jinbaicheng Metal Materials Co., Ltd., peb zoo siab ua tus thawj coj tsim khoom thiab muab khoom ntawm ASTM A500 steel pipes. Peb txoj kev cog lus los muab cov khoom zoo tshaj plaws thiab kev ua tau zoo tau tsim peb lub koob npe nrov hauv kev lag luam. Nrog rau kev tswj xyuas zoo nruj thiab pab pawg neeg txawj ntse, peb xyuas kom meej tias peb ASTM A500 Square Tube ua tau raws li thiab tshaj cov qauv thoob ntiaj teb. Peb cov kab khoom dav dav, suav nrog ASTM A500 Qib A thiab ASTM A500 Qib B, muab kev ywj pheej rau cov neeg siv khoom xaiv cov kev daws teeb meem uas haum rau lawv cov kev xav tau tshwj xeeb.
