Cov khoom siv kuaj thiab tshuaj xyuas ntawm API 5L X60 PSL2 Kab Yeeb
Ntim Kev daws ntawm API 5L X60 PSL2 Pipeline rau roj thiab roj
- Pipe Bundling & Sib cais:
Cov kav dej me me (< 8"): Use hexagonal bundles. Each bundle is secured with at least 5 high-strength steel straps. A rubber protective pad or thick cardboard is placed between the steel straps and the FBE coating; direct contact between the steel straps and the coating is strictly prohibited.
Cov Yeeb Nkab Loj Loj (Ntau dua lossis sib npaug li 10"): Thauj hauv cov khoom loj. Cov hlua khi roj hmab lossis cov hlua khi hlua khi tau muab tso rau ntawm cov khaubncaws sab nraud povtseg los tiv thaiv kev sib txhuam ntawm cov kav dej vim lub nkoj dov.
- Kev Tiv Thaiv Kawg:
Bevel xeb tiv thaiv: Cov bevels raug coated nrog siab -kev ua tau zoo pob tshab xeb{1}} tiv thaiv roj los yog kua roj vanish.
Pipe Caps: Siv tag nrho cov khoom hnyav- lub kaus mom yas. Qhov no tsis yog tsuas yog tiv thaiv kev cuam tshuam ntawm bevel tab sis, qhov tseem ceeb tshaj, tiv thaiv cov tshuaj ntsev los ntawm kev nkag mus rau hauv cov yeeb nkab thaum South American shipping thiab ua rau sab hauv corrosion.
Kev Tiv Thaiv Bevel: Rau X60 tuab- cov kav dej, steel- cov khoom tiv thaiv yas nrog cov hlau thav duab raug ntxiv los xyuas kom meej tias lub bevel tsis deform thaum lub sij hawm hoisting.
- Kev tiv thaiv UV:
Lub sij hawm tshem tawm kev lis kev cai yog ntev nyob rau hauv qee qhov chaw nres nkoj South American (xws li Santos lossis Buenaventura), thiab cov kav hlau yuav raug khaws cia rau hauv qhov chaw qhib rau lub lis piam.
Kev daws: Peb muaj kev xaiv puv - yeeb nkab dawb UV- tiv thaiv cov ntaub qhwv kom tsis txhob muaj zog UV rays los ntawm kev ua rau cov epoxy hmoov txheej rau chalk lossis tsis xim.
