Kev Ntsuas Tensile
Ntsuas lub zog tensile, tawm lub zog, thiab elongation ntawm cov yeeb nkab steel.Cov kev ntsuam xyuas no pab ntsuam xyuas cov khoom ua tau zoo thiab toughness nyob rau hauv tensile stress.
Bending Test
Kev ntsuam xyuas kev khoov yog ua los ntawm welded thiab seamless yeeb nkab los ntsuas nws cov yas deformation muaj peev xwm thiab kev ncaj ncees ntawm cov pob qij txha welded.
Flattening Test
Kev ntsuam xyuas flattening yog ua rau cov hlab ntsha los ntsuas lawv cov deformation thiab rupture yam ntxwv nyob rau hauv siab.
Kev Xeem Hardness
Lub hardness ntawm cov khoom yog soj ntsuam los ntawm txoj kev ntawm Brinell los yog Rockwell hardness test.Qhov kev ntsuam xyuas no tseem ceeb hauv kev txiav txim siab txog kev ua thiab kev siv cov yam ntxwv ntawm cov khoom.

Kev tiv thaiv txheej rau ASTM A106 GR.B
Galvanized
Galvanizing yog ib txoj hauv kev muab kev tiv thaiv corrosion los ntawm kev siv zinc txheej rau saum npoo ntawm cov hlau.
Cov txheej txheem galvanizing feem ntau yog kub dip galvanizing, nyob rau hauv uas cov yeeb nkab steel yog dipped rau hauv molten zinc los ua ib txheej tuab ntawm zinc ntawm nws qhov chaw.
Zinc txheej no tsis tsuas yog lub cev insulates cov hlau substrate los ntawm huab cua thiab dej, tiv thaiv oxidation, tab sis kuj slows tus nqi ntawm steel corrosion los ntawm sacrificial anodic tiv thaiv (zinc yog active dua hlau).
Kub-dip galvanized kho steel yeeb nkab yog tsim rau siv sab nraum zoov lossis hauv qhov chaw ntub dej, xws li cov chaw kho dej thiab cov vaj tsev sab nraum zoov.
Txheej
Txheej yog ib txoj hauv kev tiv thaiv corrosion los ntawm kev siv ib lossis ntau txheej ntawm cov txheej txheem tiv thaiv corrosion rau saum npoo ntawm cov yeeb nkab steel.
Cov txheej no tuaj yeem yog epoxy, polyurethane, polyethylene, lossis lwm yam khoom siv hluavtaws.
Epoxy txheej yog dav siv nyob rau hauv industrial piping vim lawv zoo heev tshuaj stability thiab adhesion.
Lub luag haujlwm tseem ceeb ntawm txheej txheej yog los thaiv cov dej noo thiab cov tshuaj corrosive, tiv thaiv lawv los ntawm kev sib cuag nrog cov hlau.Cov txheej txheem kev kho mob yog tsim rau ntau qhov chaw xws li cov nroj tsuag tshuaj, marine ib puag ncig thiab cov kav dej hauv nroog.
Txheej Txheej
Kev kho hauv ob sab phlu yog siv cov txheej txheem los tiv thaiv corrosive, xws li epoxy resin, ceramics, lossis roj hmab, hauv cov yeeb nkab steel los tiv thaiv corrosion ntawm cov khoom nruab nrab ntawm cov yeeb nkab hauv phab ntsa.
Txoj kev no tshwj xeeb tshaj yog tsim rau kev xa cov kua dej corrosive (xws li acids, alkalis, ntsev tov, thiab lwm yam).
Epoxy resin hauv ob sab phlu muab cov txheej txheem tiv thaiv corrosion uas tuaj yeem tiv taus qee qhov kev tawm tsam tshuaj lom neeg thiab lub cev puas.
Lub hauv ob sab phlu tsis tsuas yog txuas lub neej ntawm cov yeeb nkab, tab sis kuj tseem tswj kev huv ntawm cov kua dej thiab tiv thaiv kev sib kis.
