Hauv lub ntiaj teb sib tw ntawm B2B steel procurement, xaiv ntawm ASTM A53 Qib Athiab Qib Btsis yog tsuas yog kev txawj xwb - nws yog qhov kev txiav txim siab uas cuam tshuam rau koj qhov project txoj kev nyab xeeb thiab koj cov nqi tsaws tag nrho. Ua ib lub chaw tsim khoom ua lag luam ntawmTianjinYuantai Derun Group, peb tau pom tias kev saib xyuas me ntsis hauv cov lus qhia tuaj yeem ua rau muaj kev ua yuam kev kim heev.
Tsum Tsis Txhob Kwv Yees: Vim Li Cas Kev Xam Xaj Tam Sim No Thiaj Tseem Ceeb
Ib qho ntawm cov "kev tua peev nyiaj loj tshaj plaws" hauv kev lag luam thoob ntiaj teb yog kev kwv yees qhov hnyav tsis raug. Ntau tus neeg ua haujlwm yuav khoom vam khom cov duab kos theoretical, tab sis thaum koj suav nrog qhov hloov pauv ntawm SCH 40 mus rau SCH 80, qhov hnyav tuaj yeem dhia tau ze li ntawm 50% (piv txwv li, 6″ NPS yeeb nkab mus ntawm ~ 28.26 kg / m mus rau ~ 42.56 kg / m).
Qhov no tsis yog hais txog cov hlau xwb; nws yog hais txog koj cov khoom thauj hauv hiav txwv thiab lub peev xwm ntawm crane. Txhawm rau daws qhov no, peb tau koom ua ke Live Spec & Weight Validator hauv qab no. Tsis zoo li cov lus qhia static, cov cuab yeej no cim cov teeb meem kev tsim khoom uas yuav tshwm sim - xws li thaum qhov tuab ntawm phab ntsa thov yog qhov hnyav dhau rau cov txheej txheem ERW tus qauv.
Lub hauv paus tseem ceeb ntawm kev siv tshuab: Vim li cas peb thiaj pom zoo kom siv qib B
Txawm hais tias Qib A feem ntau raug hais txog nws cov khoom zoo heev uas khoov tau txias, ASTM A53 Qib B tseem yog "cov neeg ua haujlwm" ntawm kev lag luam. Nov yog vim li cas:
Cov Qoob Loo Zoo Dua, Cov Qauv Muaj Kev Nyab Xeeb Dua:Tsis txhob twv nrog qhov txwv 205 MPa ntawm Qib A. ASTM A53 Qib B ncaws lub zog tawm mus txog 240 MPa. Qhov 17% ntxiv zog tsis yog ib tus lej xwb - nws yog qhov sib txawv ntawm ib qhov project uas tsis tshua dhau thiab ib qho uas tau tsim rau cov khoom siv hnyav thiab cov kav dej siab.
Kev Tsim Khoom Uas Haum Rau Koj Cov Nyiaj Txiag:Qib B yooj yim heev rau kev ua haujlwm nrog ntau txoj kab tsim khoom sib txawv. Yog tias koj tab tom nrhiav kev txuag nqi, nws yog tus qauv rau ERW yeeb nkab. Yog tias koj xav tau kev ntseeg siab tshaj plaws rau qhov chaw muaj kev ntxhov siab siab, nws ua haujlwm zoo kawg nkaus li Seamless TubesNws ntaus qhov "qab zib" uas tsis tshua muaj uas koj tsis tas yuav txi qhov ductility rau lub zog.
Tshaj Li Qhov Galvanizing: Kev Siv Tshuab Txheej Txheem Siab Tshaj Plaws
Yog tias koj qhov project nyob rau hauv ib cheeb tsam ntug dej hiav txwv uas muaj salinity siab lossis raug rau cov tshuaj corrosive, tus qauv kub-dip galvanizing yuav tsis muab kev tiv thaiv txaus. Qhov ntawd yog qhov chaw uas Yuantai Derun's Zinc-Magnesium-Aluminum coatings tuaj yeem muab kev daws teeb meem txhim khu kev qha dua. Cov thev naus laus zis "Self-Healing" no muaj txog li 10 npaug ntawm kev tiv thaiv corrosion ntawm cov txheej txheem ib txwm muaj, ua rau koj cov kev saib xyuas mus sij hawm ntev txo qis.
Tau Txais Ib Daim Ntawv Qhia Txog Kev Ntseeg Tau Hauv Ob Peb Zaug Xwb
Xav tau ntau dua li qhov loj me ib txwm xwb?Xav tau kev tswj hwm R-angle kom meej lossis SHS / RHS ntev raws li koj xav tau? Peb pab neeg ua haujlwm tau npaj txhij los txhawb koj. Ntawm Yuantai Derun, peb tsis yog muab cov kav dej xwb - peb muab cov kev daws teeb meem uas ua rau kav ntev.
