Siab -Txoj Kev Siv Hluav Taws Xob Siab
Siab - cov roj thiab cov pa xa mus rau qhov kev xav tau nruj ntawm kev xaiv cov khoom siv yeeb nkab. Cov kav xa dej yuav tsum ua kom muaj kev ruaj siab nyob rau hauv lub sijhawm thaum ua kom muaj kev hloov pauv hloov pauv thaum lub sijhawm pib- nce, kaw, thiab ntws hloov pauv. Cov pa roj carbon steel kav yog tsim los ua kom tau raws li cov kev cai no los ntawm kev tswj xyuas steelmaking thiab tsim cov txheej txheem.
Lub zog thiab Ductility Balance
Lub ntsiab lus kom zoo dua ntawm carbon steel nyob rau hauv siab - kev siv siab nyob rau hauv nws qhov sib npaug ntawm lub zog thiab ductility. Thaum lub zog tawm los siab txhawb nqa lub siab, qhov elongation txaus ua kom ntseeg tau tias kev ntxhov siab hauv cheeb tsam tsis ua rau muaj kev puas tsuaj tam sim ntawd. Qhov nyiaj tshuav no yog qhov tseem ceeb rau kev nyab xeeb ntawm cov kav dej, tshwj xeeb tshaj yog nyob rau hauv ntev - kab ke.
Vuam Integrity thiab Joint Reliability
Pipeline welding yog qhov tseem ceeb hauv kev pabcuam siab -. Carbon steel exhibits zoo heev weldability, tso cai rau tsim ib tug niaj hnub weld seams nrog txhua yam khoom zoo sib xws rau lub hauv paus khoom. Qhov no txo qis kev ntxhov siab ntawm cov pob qij txha, uas feem ntau yog cov ntsiab lus yooj yim tshaj plaws hauv cov kav dej.
Siab tsim thiab phab ntsa Thickness Optimization
Cov pa roj carbon steel tso cai rau kev tswj hwm ntawm phab ntsa tuab raws li kev tsim kev ntsuas siab. Cov kws tshaj lij tuaj yeem ua kom zoo dua cov yeeb nkab tuab kom ua tiav cov kev xav tau kev nyab xeeb yam tsis tas siv cov khoom siv, ua rau tus nqi - ua haujlwm tau zoo.
Kev Tshawb Fawb thiab Kev Ntsuas Xyuas
High-siab carbon steel pipelines raug kuaj xyuas hydrostatic thiab tsis yog-kev kuaj xyuas kom paub tseeb tias lub siab ncaj ncees. Cov kev kuaj xyuas no paub tseeb tias cov yeeb nkab muaj peev xwm tiv taus kev ua haujlwm ua ntej ua haujlwm.
Siab-Cov ntaub ntawv tsim muaj
| Tsim Aspect | Tus nqi |
|---|---|
| Tsim Factor | 0.72 – 0.8 |
| Kuaj Siab | 1.25 – 1.5 × Tsim Siab |
| Yield Ratio | Tsawg dua lossis sib npaug li 0.93 |
| Weld Joint Efficiency | Ntau dua lossis sib npaug rau 1.0 |
| Kev nyab xeeb Margin | Ntau dua lossis sib npaug li 20% |
Kev ua haujlwm ruaj khov dhau sijhawm
Cov kev paub dhau los tau lees paub tias cov raj xa dej carbon steel tswj kev ruaj ntseg nyob rau lub sijhawm ua haujlwm ntev thaum kev tiv thaiv corrosion thiab kev saib xyuas cov tshuab raug siv kom raug. Lawv cov kev coj cwj pwm zoo ib yam ua kom yooj yim rau qhov ntev - kev ntsuas kev ncaj ncees.
