Sa516Gr700 Hlau phaj tau siv nyob rau hauv cov roj, roj, thiab pipelines rau corrosive ib puag ncig qhov chaw hydrogen sulfide (h₂s) yog tam sim no. Daim phiaj tshwj xeeb no muaj lub zog zoo, kev muaj zog, thiab weldability, muab kev nyab xeeb rau kev tawg thiab tsis ua haujlwm hauv cov xwm txheej hnyav.
A516 Qib 70 yog qhov kev xaiv zoo rau kev pabcuam qis dua qhov kev thov kub uas muaj qhov kub thiab kub zoo. Cov qib hlau no siv rau hauv cov hlab siab ntawm ob leeg thiab muaj boilers thiab tuaj yeem tiv thaiv kom muaj kev kub siab ntawm ntau qhov kub. Daim hlau mus txog thiab suav nrog 40mm tuab yuav tsum tau muab raws li - dov tab sis tej zaum yuav txiav txim siab ib txwm muaj. Daim phiaj tuab dua 40mm ntxiv rau cov phiaj xwm ntawm lub chaw kuaj kev nruj yuav tsum tau ua, yuav tsum yog li qub.

Khoom Paub meej
Cov phiaj hlau hlau no muaj ntau yam sib txawv. Lawv muaj lub zog dua thiab siab dua ua haujlwm. Cov khoom no tau ua tiav hauv cov txheej txheem quenching. Cov khoom lag luam no nthuav tawm cov zog ua kom muaj zog & txo qhov hnyav. Cov phiaj no yog qhov zoo ntawm kev tsim khoom, weldability, thiab formability. Cov phiaj no yog qhov zoo ntawm kev ua haujlwm kub. Lawv tau tsim thiab yuav tsum tau ua ib tus mob anneaded uas ua rau nws sib xws nrog kev tsim thiab muaj kev sib luag.
Lawv kuj tseem muaj kev tiv thaiv zoo ntawm oxidation thiab atmospheric muaj cov haujlwm. Lawv kuj tuaj yeem tiv thaiv cov nyhuv ntawm cov dej noo, huab cua, thiab chav. Lawv kuj tseem tiv thaiv cov tshuaj sib txawv thiab cov roj to. Lawv tuaj yeem tiv thaiv pitting thiab tawg. Lawv muaj kev hnav zoo thiab corrosion tsis kam.
Kuaj thiab Ntim
Peb tseem muab cov ntim ntim zoo tshaj plaws rau peb cov neeg siv khoom tom qab kev txiav txim siab ntawm cov khoom ntim cov txheej txheem. Peb txawm muab ntim rau hauv lub thawv raug uas muaj ntim muaj zog. Txhua pob tau raug taug qab los ntawm kev lag luam kom ntseeg tau tias yog xa tawm kom raug ntawm lub pob thiab ntawm {{2} lub sij hawm tus me nyuam.
Peb saib xyuas qhov kev txhawj xeeb zoo thiab lub sijhawm ntawm peb cov neeg yuav khoom muaj nqi. Peb muab cov phiaj loj zoo ua ke nrog cov sijhawm loj. Peb tseem muaj lub npe hu rau peb ntawm - lub sij hawm kev pabcuam rau txhua hom av thiab tseem nyob hauv kev lag luam.
Peb kuj tseem muab cov kev pabcuam zoo tshaj plaws rau peb cov neeg siv khoom thiab thov kom muaj cov khoom lag luam zoo rau peb cov neeg siv khoom. Peb kuj tau muab peb cov khoom lag luam ntawm tus nqi phooj ywg rau kev txaus siab ntawm peb cov neeg tau txais txiaj ntsig.
