1. Dab tsi yog qhov sib txawv ntawm cov kav dej SSAW?
Teb:SSAW cov kav dej paub txog lawv txoj kab uas hla loj. Qhov dav dav sab nraud (OD) yog los ntawm 20 ntiv tes (508 hli) txog 100 ntiv tes (2540 hli) lossis loj dua. Cov phab ntsa tuab kuj tuaj yeem sib txawv raws li qhov tsim siab thiab cov qauv tsim.
2. Dab tsi yog qhov txwv lossis qhov tsis zoo ntawm cov kav dej SSAW?
Teb:Lub ntsiab tsis zoo yog:
Cov kauv weld seam feem ntau ntev dua li cov seam ntev, uas tuaj yeem suav tias yog qhov tsis muaj zog ntawm qhov ntev dua.
Tej zaum lawv yuav muaj me ntsis rougher sab hauv piv rau cov kav dej seamless, uas tuaj yeem ua rau muaj kev sib txhuam.
Rau siab -siab, kev siv tseem ceeb, seamless lossis LSAW kav feem ntau nyiam vim lawv qhov kev sib txawv ntawm kev ntxhov siab ntau dua.
3. Yuav ua li cas qhov zoo ntawm cov vuam ntawm lub SSAW yeeb nkab kom ntseeg tau?
Teb:Kev ua tau zoo tau lees paub los ntawm kev nruj tsis yog -Kev Ntsuas Kev Ntsuas (NDT) txoj hauv kev. Cov txheej txheem tseem ceeb siv hauv online yog Ultrasonic Testing (UT), uas txuas ntxiv tshuaj xyuas tag nrho cov vuam seam rau qhov tsis xws luag xws li tawg, tsis muaj fusion, lossis porosity. Kev ntsuam xyuas ntxiv xws li X- kev kuaj kab hluav taws xob kuj tseem ua tau.
4. Hom kev tiv thaiv dab tsi yog siv rau cov kav dej SSAW?
Teb:Txhawm rau tiv thaiv corrosion, SSAW kav feem ntau coated. Common coatings muaj xws li:
FBE (Fusion Bonded Epoxy):Ib txheej nyias, ruaj thermosetting hmoov txheej.
3LPE / 3LPP (3-txheej Polyethylene / Polypropylene):Multi- txheej txheej nrog FBE, copolymer nplaum, thiab txheej txheej polyolefin rau kev tiv thaiv zoo tshaj.
Bituminous txheej:Rau ib puag ncig tsis nruj heev los yog cov kav dej.
Galvanization:Siv cov zinc txheej rau kev siv cov txheej txheem.
5. Vim li cas SSAW yeeb nkab thiaj li nrov rau piling thiab foundation ua hauj lwm?
Teb:SSAW kav yog zoo heev rau piling vim:
Lawv txoj kab uas hla loj muab siab load-cov kabmob muaj peev xwm thiab khoov tsis kam.
Cov kauv weld tuaj yeem ua rau muaj zog torsional.
Lawv yog tus nqi -kev daws teeb meem zoo rau kev tsim cov hauv paus sib sib zog nqus rau cov txuas hniav, cov tsev, thiab cov qauv sab nrauv. Cov yeeb nkab tuaj yeem raug tsav mus rau hauv av thiab tom qab ntawd ntim nrog pob zeb.
