In the process of crude oil storage and transportation, due to the high sulfur content in crude oil, ordinary steel is exposed to wet H2S environment for a long time, which is prone to hydrogen-induced cracks and hydrogen sulfide stress corrosion cracking, burying a Suur ohutusoht ohutu tootmise jaoks.
In response to the above problems, hydrogen-resistant steel has been widely used in major domestic petrochemical, thermal power, desulfurization tower and other projects due to its good resistance to hydrogen-induced cracking and sulfide stress corrosion cracking. Tavalised hinded on 16mnr (HIC), Q345/Q355 (HIC), API 5L X52, ASTM A516 GR.70 (HIC).
Praegu on Hiina terasveskid lõpetanud vesinikuresistentse terase sõltumatu toodamise, asendades edukalt imporditud tooteid. With the gradual development of large-scale petrochemical equipment, in order to improve production efficiency, the market urgently needs a high-efficiency welding material for production welding. Our company has launched a submerged arc welding wire and flux that match the base metal with excellent resistance to hydrogen-induced cracking and sulfide stress corrosion cracking.
