Product Uses & Advantage
Uses
High-Pressure Reactor Vessels - Thick-walled castings for hydrocrackers and catalytic reformers that maintain structural integrity under cyclic thermal stresses and hydrogen embrittlement risks in refinery operations.
Sour Gas Processing Equipment - Specialized valve bodies and compressor components resistant to hydrogen sulfide attack (NACE MR0175 compliance) in gas sweetening units.
Cryogenic Storage Systems - LNG pump casings and valve manifolds that retain ductility at -162°C while preventing brittle fracture in liquefied natural gas transfer systems.
Advantages
Corrosion Management - Dual-phase stainless steel microstructures with 25%+ chromium content provide unmatched resistance to pitting, crevice corrosion, and stress cracking in chloride/sulfide environments.
Thermal Fatigue Resistance - Directionally solidified castings with controlled grain boundaries prevent crack propagation during repeated thermal cycling (500+ cycles) in furnace components.
Integrated Safety Features - Monolithic designs eliminate welded joints in pressure-containing parts, reducing potential leak paths in flammable/ toxic service applications.
Product Application
The Petrochemical Casting Parts is a kind of petrochemical machinery. Here are some specific application scenarios of petrochemical machinery parts:
Subsea Production Trees - Large-scale, corrosion-resistant cast bodies for 3000m deepwater wellheads integrating multiple valve functions with 25-year design life.
Ethylene Cracker Components - Pyrolysis gas transfer line elbows and quench headers resisting carburization at 900°C in olefin production plants.
Sulfur Recovery Units - Claus process reactor internals handling wet sulfuric acid condensation with specialized alloy protection against acid dew point corrosion.
