1. Hydrostatic Testing yog dab tsi, thiab yog vim li cas nws thiaj li ua rau txhua LSAW yeeb nkab?
A:Nws yog ib qho kev sim uas txhua ntu cov yeeb nkab tau ntim nrog dej thiab ua kom siab mus rau qib siab dua li qhov xav tau ntawm kev ua haujlwm siab. Qhov no txheeb xyuas qhov kev ncaj ncees ntawm cov txheej txheem thiab cov xau- nruj ntawm cov yeeb nkab thiab nws cov vuam ua ntej nws tawm hauv lub tshuab.
2. Kev txhim kho corrosion ntawm LSAW kav dej li cas?
A:Sab hauv thiab sab nraud, lawv muaj kev tiv thaiv nrog coatings. Sab nraud, Fusion-Bonded Epoxy (FBE) lossis 3-Layer Polyethylene (3LPE) txheej yog tus qauv. Sab hauv, epoxy hauv ob sab phlu yog ntau. Rau ib puag ncig corrosive heev,Kev tiv thaiv Cathodicyog siv ua ke nrog coatings.
3. Dab tsi yog qhov tseem ceeb ntawm Kev Npaj Ua Yeeb Yam?
A:Cov yeeb nkab kawg yog beveled rau ib lub kaum ntse ntse kom yooj yim rau siab -welding zoo thaum lub sij hawm tsim cov kav dej. Precise beveling ua kom zoo sib xws thiab nkag mus ntawm lub girth welds txuas cov yeeb nkab ib leeg.
4. Qhov ntev npaum li cas ntawm cov yeeb nkab LSAW yog dab tsi?
A:Thaum qhov sib txawv, qhov ntev ib txwm random nyob ib puag ncig12 m (40 ko taw). Cov kav dej kuj tuaj yeem ua ob npaug - sib koom ua ke ntawm lub zeb los tsim cov ntu ntev (xws li 24 meters) kom txo tau cov welds.
5. Dab tsi yog qhov tseem ceeb cuam tshuam rau tus nqi ntawm LSAW yeeb nkab?
A:Cov yam tseem ceeb muaj xws li:
Raw khoom (steel phaj) nqi.
Cov yeeb nkab qhov ntev (inch, phab ntsa thickness, ntev).
Cov qib steel thiab cov khoom tsim nyog (xws li X70 kim dua X52).
Hom thiab qhov ntev ntawm kev kuaj thiab tshuaj xyuas.
Kev tiv thaiv txheej txheem.
