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 hlau tsim thiab muab khoom, Shandong Zhongao Steel 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 hlau 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 ntawm ASTM A500 cov kav hlau txheem:
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 ib
