Kev faib tawm qhov tseem ceeb: PSL 1 vs PSL 2 (Qeb yam khoom tshwj xeeb)
PSL1 (Standard Qib)
- Basic chemical muaj pes tsawg leeg & mechanical test xwb
- Tsis tas yuav tsum xeem Charpy cuam tshuam rau cov qhab nia li niaj zaus
- Rau cov av dav dav / nruab nrab- cov kav dej siab, cov haujlwm tsis zoo ib yam - cov haujlwm tseem ceeb
- Tus nqi qis dua, kev xa khoom luv luv
PSL2 (High-Strict Premium Grade, Ntiaj teb no Major Project yuav tsum tau)
- Tighter tswj ntawm carbon, sulfur, phosphorus tshuaj txwv
- 100% Charpy V-notch low-temperature impact test
- Tag Nrho NDT (UT, Eddy Tam sim no, Hydrostatic Test rau txhua cov yeeb nkab)
- Strict dimensional & phab ntsa thickness kam rau ua
- Yuav tsum tau rau sab ntug dej hiav txwv, qaub H₂S roj, sib sib zog nqus faus, siab -pressure main pipelines, thoob ntiaj teb bidding project
Nto Anti-Corrosion Options for Export
- Dub kua roj vanish:luv-lub caij hla hiav txwv tiv thaiv- xeb, tus nqi qis
- 3LPE / 3PP txheej txheej sab nraud:faus ntev pipeline txheem tiv thaiv -corrosion (80-300μm thickness)
- FBE fusion bonded epoxy:Tib - txheej tiv thaiv - corrosion rau thaj chaw suab puam & ntug hiav txwv ntsev
- Internal epoxy txheej:Txo cov kua dej sib txhuam, tiv thaiv sab hauv corrosion
- Kev tiv thaiv yeeb nkab kawg:Xiav / liab lub kaus mom los tiv thaiv vuam bevel thaum xa khoom
Kev kho saum npoo
Main Application Fields
- Upstream:Cov kab sib sau ua ke roj zoo, cov kav dej zoo ntws, cov kav dej txhaj tshuaj
- Nruab nrab:Hla-lub teb chaws ntev- deb ntawm cov roj crude & cov pa roj carbon monoxide trunks, offshore subsea pipelines
- Hauv qab:City municipal natural gas network, refinery process pipelines, roj tsheb thauj mus los pipelines
- Kev pab tshwj xeeb:Cov kav dej qaub qaub (H₂S nruab nrab, ua raws API 5L Annex H), qis -kub arctic pipeline, offshore platform piping
FAQ
Q: Qhov txawv ntawm API 5L thiab ASTM A106 yog dab tsi?
A: A106 seamless yeeb nkab yog rau siab -cov khoom kub / cua sov; API 5L tshwj xeeb yog tsim los rau ntev -nruab nrab ntawm cov roj thiab cov kua roj xa mus, nrog cov qauv nruj dua thiab cov qauv weldability rau kev tsim cov kav dej.
Q: Koj puas muab PSL2 X70 LSAW yeeb nkab rau txawv teb chaws lub cev kab ua haujlwm?
A: Brisk Steel tag nrho cov khoom lag luam npog Gr.B ~ X80, ob qho tib si PSL1 & PSL2, ua tiav SMLS / ERW / LSAW cov kab ntau lawm, tag nrho dhau thib peb- tog SGS / BV tshuaj xyuas, ua tau raws li Saudi, Qaib ntxhw, Poland, New Zealand qhov project qauv, MOQ 25 tons.
Q: Qhov kev ntsuam xyuas ua li cas tag nrho API 5L kav dej?
A: 100% hydrostatic siab kuaj; online ultrasonic weld soj ntsuam rau welded kav; tshuaj ntsuam xyuas muaj pes tsawg leeg; xeem tensile; PSL2 kev txiav txim ntxiv tag nrho qis - ntsuas qhov ntsuas kub.
Q: Peb puas tuaj yeem muab kev cai phab ntsa thickness & tiv thaiv -corrosion txheej?
A: Kev cai OD, WT, ntev (6m / 12m random ntev lossis ruaj txiav ntev) muaj; Txhawb 3LPE, FBE, sab hauv epoxy txheej raws li ib tus neeg siv khoom xav tau kos duab.
