Nkag siab txog ASTM A252 Pipe
Nyob rau hauv lub ntiaj teb no ntawm kev tsim kho thiab civil engineering, kev xaiv cov khoom yog ib qho tseem ceeb los xyuas kom meej cov kev ncaj ncees thiab ntev lub neej ntawm ib tug qauv. Ib yam khoom uas muaj kev hwm hauv kev lag luam yog ASTM A252 yeeb nkab. Qhov kev qhia tshwj xeeb no yog qhov tseem ceeb tshwj xeeb rau cov neeg ua haujlwm nrog cov phiaj xwm piling, raws li nws npog cylindrical nominal phab ntsa thickness steel yeeb nkab pawg.
Dab tsi yogASTM A252, ASTM A252?
ASTM A252 yog tus qauv kev qhia tshwj xeeb uas qhia txog qhov yuav tsum tau ua rau cov welded thiab seamless steel yeeb nkab pawg. Cov kav dej no tau tsim los siv los ua cov tswvcuab cov kabmob mus tas li lossis ua cov plhaub rau cov pob zeb cast-in-place. Qhov kev qhia tshwj xeeb no yog qhov tseem ceeb los xyuas kom meej tias cov kav dej tuaj yeem tiv taus qhov kev ntxhov siab thiab kev thauj khoom uas tuaj yeem ntsib hauv ntau yam kev siv, tshwj xeeb tshaj yog hauv paus engineering.
CovASTM A252 Yeeb Nkabspecification tau muab faib ua peb qib, txhua qhov sib txawv yield zog yuav tsum tau. Lub zog siab tshaj plaws tuaj yeem ncav cuag li 450MPa, ua rau nws haum rau cov khoom siv hnyav xws li Choj thiab cov tsev siab.
Cov qauv siv tau ntev: Nws tuaj yeem siv los ua cov khoom siv thauj khoom mus tas li lossis lub plhaub ntawm cov pob zeb ua pob zeb, tiv thaiv qhov chaw hauv av corrosive.
Kev hloov pauv tau yooj yim: Txoj kab uas hla ntau Φ219mm-Φ3500mm, phab ntsa thickness 6-25.4mm, haum rau txoj kev geological tej yam kev mob
Peb lub zog tseem ceeb
Nrog rau kev lag luam-kev tsim muaj peev xwm, muaj peev xwm tsim tau ib xyoos ib zaug ntawm ntau dua 500,000 tons, nws muaj ib qho ntawm ob peb txoj kab hauv tsev rau cov kab loj Φ3500mm kauv steel kav
Cov txheej txheem submerged arc vuam (SAW) tau txais yuav, thiab cov vuam zoo tau lees paub los ntawm kev kuaj tsis muaj kev puas tsuaj xws li X-rays thiab ultrasonic tsis.
Full-txheej txheem kev tswj kom zoo
Los ntawm raw khoom mus rau cov khoom tiav, lubAstm A252 Tubetus qauv yog nruj me ntsis siv
Nws yog txawm peem rau nrog epoxy anti-corrosion / 3PE anti-corrosion kev kho mob, uas txuas ntxiv lub neej kev pab cuam nyob rau hauv Marine ib puag ncig los ntawm ntau tshaj 30%
Kev pabcuam thoob ntiaj teb
Cov khoom raug xa tawm mus rau ntau tshaj 30 lub teb chaws suav nrog Tebchaws Europe, Amelikas, Southeast Asia thiab Middle East
Txhawb customized ntau lawm thiab muab kev pabcuam ib-nres los ntawm kev xaiv rau kev tsim kho kev taw qhia
Tag nrho hauv tag nrho, ASTM A252 cov kav dej yog ib qho tseem ceeb hauv kev tsim kho thiab kev tsim vaj tsev engineering, muab qhov tsim nyog lub zog thiab kav ntev rau ntau yam kev siv. Cangzhou Spiral Steel Pipe Group Co., Ltd. yog lub chaw tsim khoom ntawm cov yeeb nkab no, muab ntau qhov ntau thiab tsawg thiab phab ntsa thicknesses kom tau raws li cov kev xav tau tshwj xeeb ntawm peb cov neeg siv khoom. Txawm hais tias koj tab tom ua haujlwm ntawm piling tej yaam num lossis lwm yam kev tsim kho, kev nkag siab txog qhov tseem ceeb ntawm ASTM A252 cov kav dej thiab ua haujlwm nrog cov chaw tsim khoom txhim khu kev qha yuav yog qhov tseem ceeb rau kev ua tiav ntawm koj qhov project.
