Petrochemical industry, abbreviated as petrochemicals. Generally refers to the chemical industry that uses oil and natural gas as raw materials. The scope is wide and there are many products. Crude oil undergoes cracking, reforming, and separation to provide basic raw materials such as ethylene, propylene, butene, butadiene, benzene, toluene, xylene, naphthalene, etc. Various basic organic materials such as methanol, formaldehyde, ethanol, acetaldehyde, acetic acid, isopropanol, acetone, phenol, etc. can be produced from these basic raw materials.
Some characteristics of corrosion-resistant alloy fasteners: they have superior resistance to medium erosion in extremely corrosive environments, and the use of alloying methods to obtain corrosion-resistant alloys improves the thermodynamic stability of metals or alloys. Widely used in chemical equipment, pump and valve fluids, pharmaceutical papermaking, boiler containers, water treatment, desulfurization and denitrification, etc.
