Taw qhia rau Mild Steel RHS, SHS, MS ERW Dub Square thiab Rectangular Hollow Section Pipes

Txhais thiab Classification

Cov hlau me me yog qhov qis - carbon steel nrog cov ntsiab lus carbon feem ntau tsawg dua 0.25%. RHS (Rectangular Hollow Section) thiab SHS (Square Hollow Section) yog hom hollow - seem kav. MS stands rau Mild Steel, thiab ERW hais txog hluav taws xob tsis kam vuam, uas yog cov txheej txheem siv los tsim cov kav dej. Cov kav dej yog nyob rau hauv cov xim dub, txhais tau tias lawv tsis tau txais kev kho saum npoo ntxiv xws li galvanizing. Cov duab plaub thiab cov duab plaub ua rau lawv haum rau ntau yam ntawm cov qauv thiab tsis yog cov qauv siv.

Tej kev siv

Cov kav dej no yog siv rau hauv kev tsim kho, rooj tog zaum, thiab kev tsim kho tshuab. Hauv kev tsim kho, lawv tuaj yeem siv rau lub tsev thav duab, kab, thiab trusses. Piv txwv li, nyob rau hauv kev tsim kho ntawm ib qho yooj yim shed, RHS los yog SHS kav yuav siv tau los ua tus ncej ntawm lub ru tsev thiab phab ntsa. Hauv kev tsim cov rooj tog, lawv tau siv los tsim cov thav ntawv ntawm cov rooj zaum, rooj, thiab txaj. Hauv kev tsim kho tshuab, lawv ua haujlwm rau cov kua dej lossis ua cov tswv cuab hauv cov tshuab ua haujlwm.

Cov khoom ntawm Mild Steel RHS, SHS, MS ERW Dub Pipes

Mechanical Properties

Lub zog tawm ntawm cov kav dej me me feem ntau yog nyob ntawm 200 - 250MPa, thiab lub zog tensile nyob ib ncig ntawm 300 - 400MPa. Cov khoom no muab cov kav dej uas muaj zog txaus los nqa cov khoom hauv ntau yam kev siv. Lub ductility ntawm cov hlau me me tso cai rau cov kav dej yuav khoov lossis tsim rau hauv cov duab sib txawv yam tsis muaj kev tawg. Qhov elongation ntawm kev tawg tuaj yeem nyob ib puag ncig 20 - 30% nyob ntawm qib tshwj xeeb thiab cov txheej txheem tsim khoom. Qhov ductility no muaj txiaj ntsig zoo hauv cov ntawv thov uas cov kav dej yuav tsum tau ua kom zoo li lub sijhawm teeb tsa lossis tsim khoom.

Cov kav dej kuj muaj kev cuam tshuam zoo. Lawv tuaj yeem tiv taus qhov cuam tshuam nruab nrab yam tsis muaj kev puas tsuaj loj. Txawm li cas los xij, hauv cov ntawv thov uas yuav tsum muaj kev tiv thaiv siab, yuav tsum muaj kev txhawb nqa ntxiv lossis tuab dua - cov kav dej uas muaj phab ntsa.

Corrosion Resistance

Raws li cov kav dej no nyob rau hauv lub xeev dub (un - galvanized), lawv cov kev tiv thaiv corrosion kuj tsawg dua piv rau cov kav dej galvanized. Cov hlau me me yog yooj yim rau xeb thaum raug ya raws thiab huab cua. Tus nqi ntawm corrosion nyob ntawm ib puag ncig yam xws li av noo, kub, thiab muaj cov khoom corrosive. Nyob rau hauv ib qho chaw qhuav hauv tsev, tus nqi corrosion yuav qeeb, tab sis nyob rau hauv ib qho chaw ntub dej los yog sab nraum zoov, cov kav dej yuav xeb sai dua. Txhawm rau txhim kho corrosion kuj, cov kav dej tuaj yeem pleev xim, coated nrog xeb - tus neeg saib xyuas kev tiv thaiv, lossis galvanized.

Dimensional thiab Geometric Properties

Cov duab plaub thiab cov duab plaub ntawm cov kav dej muaj qee qhov zoo ntawm kev thauj khoom - kev coj tus kheej thiab qhov chaw - kev siv. Qhov ntev ntawm cov kav dej, nrog rau cov qhov ntev ntawm sab nrauv thiab phab ntsa tuab, tuaj yeem kho raws li qhov xav tau ntawm daim ntawv thov. Cov phab ntsa thickness cuam tshuam rau lub zog thiab qhov hnyav ntawm cov kav dej. Cov yeeb nkab tuab-walled muaj zog dua tab sis kuj hnyav dua. Cov kav dej muaj qhov ruaj khov zoo, uas txhais tau tias lawv tuaj yeem tswj tau lawv cov duab thiab qhov loj me thaum tuav, kev thauj mus los, thiab kev teeb tsa.
