x80 qwyog lub siab -lub zog seamless steel yeeb nkab tsim tshwj xeeb rau cov chaw pabcuam acidic raws li API 5L PSL2 tus qauv. "X80" sawv cev rau qhov tsawg kawg nkaus tawm lub zog ntawm 555 MPa (80 kb / sq inch), thiab "QS" cov lus qhia tshwj xeeb qhia tau tias nws tau dhau los ua pov thawj tiv thaiv corrosion hauv acidic ib puag ncig.
Cov khoom siv no siv TMCP thermomechanical tswj txheej txheem thiab microalloying thev naus laus zis kom ua tiav kev sib tw hauv ob qho tib si hydrogen -induced cracking (HIC) thiab sulfide stress corrosion (SSC) tsis kam thaum ua kom lub zog tawm ntawm ntau dua 555 MPa. Qhov no tau ua tiav los ntawm kev tswj hwm nruj ntawm sulfur thiab phosphorus impurity cov ntsiab lus thiab microstructure (accicular ferrite cov ntsiab lus Ntau dua lossis sib npaug li 80%).
Master H2S kev sib tw nrog peb API 5L X80QS pipelines. Ua raws li Annex H, peb cov kav dej tau raug kuaj HIC thiab SSCC kom ntseeg tau tias xoom- ua haujlwm tsis zoo hauv kev pabcuam qaub.Thov peb cov ntaub ntawv ntsuam xyuas kev tshaj lij thiab cov ntaub ntawv ua raws Annex H tam sim no!

API 5L X80QS Kab Pipes rau roj & roj Tshwj xeeb Logistics rau Sour Service Pipelines
1. Kev tiv thaiv kev ruaj ntseg zoo heev
Nyob rau hauv acidic ib puag ncig, txhua yam kev puas tsuaj ntau tshaj 5% ntawm cov yeeb nkab phab ntsa thickness (xws li khawb los ntawm steel hlau ropes) yog nruj me ntsis txwv tsis pub.
- Nylon Slings nkaus xwb: Peb nruj me ntsis txwv tsis pub siv cov hlau xaim hlua thaum txhua yam hauv - cog thiab chaw nres nkoj ua haujlwm. Tsuas yog nylon slings nruab nrog cov padding hloov tau yooj yim lossis tshwj xeeb lub tshuab nqus tsev nqa khoom tau tso cai.
- Roj Hmab-Padded Saddles: Thaum thauj mus rau cov tsheb thauj khoom lossis stowed hauv lub nkoj tuav, cov kav dej tsis raug tso cai los rau hauv kev sib cuag ncaj qha nrog cov hlau; Hloov chaw, lawv tau zaum hauv cov ntoo nkhaus uas haum nrog cov roj hmab tiv thaiv kom tsis txhob muaj kev vibration -induced abrasion thaum caij tsheb npav.
2. Ntau-Txheej Txheem Kev Tiv Thaiv rau Beveled Ends thiab Yeeb Nkab Terminals (Precision Pipe End Protection)
Qhov siab -qhov tshwj xeeb muaj zog ntawm X80QS cov kav dej xav tau kev sib txawv tsis zoo thaum lub sijhawm ua haujlwm vuam.
- Hnyav-Lub Luag Haujlwm Steel End Protectors: Tsis zoo li cov kav dej txheem, uas feem ntau siv cov kaus mom yas yooj yim, peb muab X80QS cov kav dej nrog bolted - ntawm steel kawg tiv thaiv. Cov kev tiv thaiv uas muaj zog no muaj peev xwm tiv taus lub zog ntawm lub zog ntawm kaum tawm tons thaum tuav haujlwm, yog li xyuas kom meej tias cov yeeb nkab beveled kawg nyob twj ywm tsis muaj deformation.
- Internal Sealing and Desiccation: The pipe ends are sealed with watertight caps, and desiccant packets are placed inside the pipe bore to prevent internal pitting corrosion caused by the high-salinity marine atmosphere encountered during sea transport.
3. Cov txheej txheem thauj khoom ceev ceev rau 3LPE / 3LPP txheej (txheej txheej tiv thaiv)
X80QS kav feem ntau tiv thaiv los ntawm peb- txheej polyethylene (3LPE) los tiv thaiv- txheej txheej; Kev tiv thaiv cov txheej txheem no yog qhov tseem ceeb rau kev tiv thaiv cov yeeb nkab steel nws tus kheej.
- Separator Planks: Thaum cov kav dej tau muab tso rau hauv ntau cov khaubncaws sab nraud povtseg, cov yas mos los yog cov ntoo cais tawm ntawm txhua txheej los tiv thaiv kev sib cuag ncaj qha thiab kev sib tsoo ntawm cov kav dej, yog li tshem tawm cov kev pheej hmoo ntawm txheej txheej puas los yog detachment (uas yuav ua rau "Hloov Kev Tshawb Nrhiav Tsis Ua Haujlwm").
- Hiav txwv-Txhim kho thiab ruaj ntseg: Tsis yog- cov hlua khi hlau yog siv los tiv thaiv cov khoom thauj, thiab tiv thaiv- lub tes tsho tiv thaiv raug teeb tsa ntawm txhua qhov chaw tiv tauj kom tiv thaiv chafing.
4. Tag Nrho Traceable Digital Identification thiab Marking (Digital Traceability & Marking)
- Nyob rau hauv loj - cov roj thiab roj tej yaam num, misidentifying ib yeeb nkab - tshwj xeeb, siv ib tug uas tsis yog -acid- yeeb nkab resistant nyob rau hauv ib tug acid- ib cheeb tsam - tuaj yeem ua rau muaj kev puas tsuaj loj. Huab cua-Resistant QR Code Labels: Cov ntawv lo tseem pom meej meej txawm tias tom qab 60 hnub ntawm kev thauj mus los hauv hiav txwv. Los ntawm kev luam theej duab QR code, cov neeg siv khoom tuaj yeem nkag ncaj qha mus rau HIC daim ntawv xeem thiab MTC rau cov yeeb nkab tshwj xeeb hauv online.
- Hard Stamping Verification: Ib qho meej "API 5L X80QS PSL2" stamp yog siv rau hauv cov yeeb nkab kawg, kom ntseeg tau cov cim tshwj xeeb.
