Vim li cas thiaj xaiv kojFA steel yeeb nkab
Tianjin Youfa steel yeeb nkab Thoob dav:, Ltd. Lub Kaum Ob Hlis 2020, kojFA pab pawg ntse tau tsaws rau ntawm cov yeeb nkab loj
Peb tau tsim lub sijhawm ntev -} Term kev koom tes nrog ntau tus neeg siv khoom ntawm Api5L, ISO18000, ISO18000, ISO18000, ISO18000, ISO18000, yog tau cog lus kom tau raws li cov qhua tuaj noj mov tom qab.
Cov qauv hlau steel ua tau raws li cov qauv hauv qab no: API 5L, ASTM A53 / A500, DIN2440, thiab lwm yam. Lawv tau dav siv hauv cov roj thiab cov nkev roj, tsis tshua muaj siab ua kua thiab ua kom zoo nkauj cov khoom siv, thiab rau cov khoom lag luam thiab kev sib koom tes.
Dab tsi yog square style leeg hu ua?
Square steel tubes muaj feem ntau hu ua "square hollow ntu ntu" lossis "square steel hollow cov ntu" hauv kev lag luam. Tej zaum lawv yuav tau hu rau "square steel kav" lossis "square hlab" rau luv.
Hauv qee lub tebchaws, lawv yuav raug xa mus rau "square steel hollow cov ntu" lossis "xwm fab xwm txheej". Kuj tseem hu ua "square steel hollow kav dej" lossis "square qauv cuab plaws".
Cas koj ntsuas cov xwm txheej lossis lub voos khaub ncaws loj?
Txhawm rau ntsuas qhov loj ntawm cov xwmfab lossis cov kav dej sib dhos, ob qhov loj me yuav tsum tau txiav txim siab: sab hauv ntev thiab phab ntsa tuab thiab phab ntsa.
Lub sijhawm sab nraud yog qhov deb ntawm ib qho sab nraud ntawm ib qho xwm fab xwm fab xwm meem {}}}}}}}}}}}} tuaj yeem ntsuas siv lub digital caliper lossis steel hlau. Feem ntau ntsuas hauv millimeters (hli), centimeters (cm), lossis ntiv taw.
Rau qhov ntev sab nraud, muab cov cuab yeej ntsuas sib txuas ntawm ib sab ntawm tus ntoo xwmfab {}}} p} pend section to rau ntug, thiab ntsuas los ntawm ib sab ntug mus rau lwm qhov. Rau cov ntawv sib dhos hlau, vim muaj ob sab sib txawv ntev, nws yog qhov tsim nyog los ntsuas qhov ntev thiab dav ntawm sab nraud duab plaub. Tsis tas li ntawd kom ntseeg tau tias ntsuas ntsuas tau txiav mus rau ntug.
Rau phab ntsa thickness, cov tuab yog ntsuas los ntawm kev ua tib zoo tso lub puab tsaig ntawm lub raj nplaim sab hauv thiab sab nraud ntawm ob qho kev ntsuas yog lub phab ntsa tuab. Nws yog ib qho tseem ceeb rau kev ntsuas ntawm ntau qhov chaw nyob ib puag ncig cov raj xa dej los xav txog cov kev hloov pauv ntawm cov tuab.
Piv txwv li, yog hais tias qhov ntev ntev ntawm lub raj square yog 50 hli thiab phab ntsa tuab yog 3 hli, nws tau piav qhia raws li 50 x 50 x 4 square raj. Lub sijhawm ntev yog 50- (2 x 3) {9=44 mm, thiab cov raj xa dej tseem tuaj yeem piav qhia raws li cov pipeline square ntawm 44 x 44 x 3 hli. Yog hais tias sab nrauv ntev ntawm cov kab hlau sib dhos yog 80 mm, sab nraud dav yog 4 hli, nws tau piav raws li 80 x 4 lub voos voos voos hlau. Lub sijhawm ntev tshaj plaws yog 80- (2 x 4)=72 mm, thiab qhov dav dav yog 60- (2 x 5) {mm.
Qhov kawg FAQ qhia rau Scaffolding raj
Dab tsi yog square raj hlau?
+
-
Square tube metal refers to a type of structural material in the form of a hollow tube with a square cross-section. Nws yog feem ntau ua los ntawm ntau cov hlau lossis alloys, nrog cov hlau ua cov raj muaj feem ntau.Netal square raj muaj ob peb qhov zoo. Nws muab lub zog zoo thiab nruj vim nws cov duab thiab cov khoom siv. Nws tuaj yeem yog cov ntaub qhwv thiab welded yooj yim, tso cai rau kev tsim cov qauv sib txawv thiab cov khoom lag luam thiab cov ntawv thov ntawm cov hlau lossis alloy siv. Cov piv txwv mor, steel square hlab yog dav siv nyob rau hauv kev tsim kho rau cov thav duab, laj kab, thiab tuav tes.
