High-Structureal Steel Pipes: Lub Load-Bearing Backbone of High-End Projects
Hauv high-kawg teb xws li super siab- cov tsev nce siab, ntev - txuas txuas, marine engineering, thiab cov tshuab hnyav, siab - lub zog steel yeeb nkab sawv tawm vim lawv cov khoom siv kho tshuab zoo tshaj, txhim khu kev qha kev ruaj ntseg, thiab zoo heev engineering adaptability. Lawv tau dhau los ua cov khoom tseem ceeb rau kev txhim kho lub teeb yuag, siab - lub zog, thiab cov khoom ruaj khov ntawm cov qauv hlau niaj hnub, thiab qhov tseem ceeb lav rau kev nyab xeeb thiab kev ua haujlwm ntawm cov haujlwm loj.
1. Cov Khoom Siv Tshwj Xeeb & Cov Qauv Txuj Ci - Cov Khoom Siv Ua Haujlwm Zoo
High-lub zog steel yeeb nkab yog tsim los ntawm siab-zoo qis- alloy siab-lub zog steel (HSLA) thiab carbon structural steel. Cov qib feem ntau suav nrog Q355B/C/D/E, Q460, Q500, Q690 ultra- qib siab zog thiab 40CrNiMoA. Tag nrho cov khoom ua raws li cov qauv hauv tebchaws xws li GB/T 8162 thiab GB/T 1591, thaum qib siab -qib kawg raws li cov kev qhia tshwj xeeb thoob ntiaj teb.
Nrog rau micro- alloy cov ntsiab lus xws li Niobium, Vanadium thiab Titanium ntxiv thiab qis carbon sib npaug tsim, cov hlau ua tiav qhov kev pom zoo ntawmsiab zog, siab toughness thiab zoo heev weldability, daws cov teeb meem ib txwm muaj ntawm siab - lub zog steel yog muaj zog tab sis nkig los yog tawv tab sis nyuaj rau vuam.
Kev siv cov txheej txheem metallurgical zoo tshaj plaws suav nrog cov hluav taws xob ua kom zoo thiab lub tshuab nqus tsev degassing, teeb meem impurities xws li sulfur thiab phosphorus yog tswj nruj me ntsis, txo cov uas tsis yog -hlau inclusions thiab kom ntseeg tau tias cov khoom zoo ib yam thiab ruaj khov ntawm qhov chaw.
Nws lub zog tawm los ntawm 355MPa txog 690MPa, thiab qib siab zog siab tshaj 690MPa. Tensile lub zog ncav cuag 470-950MPa nrog zoo heev tsawg -kub qhov toughness. Nws deb tshaj qhov zoo tib yam Q235 steel kav thiab yog tsim rau hnyav load, tsis tshua muaj kub thiab alternating kev nyuaj siab heev ua hauj lwm tej yam kev mob.
2. Advanced Production Technology - Precise Quality Control
Kev txhawb nqa los ntawm cov kab tsim khoom ntse thiab tag nrho - txheej txheem tswj kev ua haujlwm zoo, siab - lub zog ntawm cov kav hlau steel txais cov txheej txheem zoo xws li seamless rolling / longitudinal welded forming, TMCP thermo-txheej txheem tswj dov thiab txias, thiab precision tshav kub kho, ntsuas kev ua haujlwm siab thiab kev ua haujlwm ruaj khov.
Txheej Txheem Ntau Lawm
Seamless steel yeeb nkab: steel billet cua sov → tho → kub dov → tiav → kho cua sov → tsis yog - kuaj kev puas tsuaj → kev tshuaj xyuas tiav
Longitudinal welded yeeb nkab: High- lub zog steel phaj pretreatment → yeeb nkab dov → submerged arc vuam → vuam tshuaj ntsuam → kub kho → sizing thiab xov
Core Txheej Txheem ZooTMCP thev naus laus zis tau tswj hwm qhov kub thiab txias, deformation thiab txias ceev kom ua kom zoo dua cov qauv, txhim kho lub zog thiab toughness. Multi-theem kev kho cua sov xws li normalizing, quenching thiab tempering tshem tawm cov kev ntxhov siab seem thiab ua kom ruaj khov qhov ntev yam tsis muaj deformation.
High- cov khoom kawg tau txais kev kos duab txias thiab txias dov kom nruj qhov ntev ntev thiab du nto, ua tau raws li qhov siab - qhov yuav tsum tau ua los ua ke. Tag nrho cov kav dej tau txais 100% ultrasonic thiab eddy tam sim no flaw nrhiav kom tshem tawm cov teeb meem sab hauv xws li tawg thiab laminations.
