Kwinkqubo yokugcinwa kwe-oyile ekrwada kunye nokuthutha, ngenxa yesiqulatho esiphezulu sesulfure kwi-oyile ekrwada, intsimbi eqhelekileyo ibonakaliswe kwindawo emanzi ye-H2S ixesha elide, ethambekele kwiintanda ezibangelwa yi-hydrogen-induced kunye ne-hydrogen sulfide stress corrosion cracking, ukungcwaba a ingozi enkulu yokhuseleko kwimveliso ekhuselekileyo.
Ukuphendula kwezi ngxaki zingasentla, i-hydrogen-resistant steel isetyenziswe ngokubanzi kwi-petrochemical yasekhaya enkulu, amandla okushisa, inqaba ye-desulfurization kunye nezinye iiprojekthi ngenxa yokuchasana kakuhle nokuqhekeka kwe-hydrogen-induced cracking kunye ne-sulfide stress corrosion cracking. Amabakala aqhelekileyo yi-16MnR (HIC), Q345 / Q355 (HIC), i-API 5L X52, i-ASTM A516 Gr.70 (HIC).
Okwangoku, iintsimbi zetsimbi zaseTshayina ziye zagqiba imveliso ezimeleyo ye-hydrogen-resistant steel, ithatha indawo ngempumelelo yeemveliso ezivela kwamanye amazwe. Ngophuhliso oluthe ngcembe lwezixhobo ezinkulu zepetrochemical, ukuze kuphuculwe ukusebenza kakuhle kwemveliso, imarike ifuna ngokukhawuleza imathiriyeli yokuwelda esebenza ngokufanelekileyo kwimveliso yokuwelda. Inkampani yethu iye yaphehlelela i-arc yokuntywila yocingo kunye ne-flux ehambelana nesiseko sesinyithi esinokumelana okugqwesileyo kokuqhekeka kwe-hydrogen-induced cracking kunye ne-sulfide stress corrosion cracking.
Iimpawu ezibonakalayo kunye neekhemikhali ze-hydrogen-resistant steel submerged arc welding wire GWL-W10KHMSHA eneflux GXL-121 ephuhliswe yinkampani yethu yile ilandelayo:
