Precision Casting Components Fabricated -NACE
The application of precision cast components run through the entire industry chain of oil & gas field: exploration, extraction, transportation, and refining & chemical processing.
The selection of steel casings in the petroleum industry revolves around working medium,corrosion and wear risks. Carbon steel castings are suitable for conventional medium – low pressure non-corrosive conditions, low alloy steel castings for high or ultra high pressure, medium high temperature, and H2S/CO2-containing oil and gas media. Stainless steel castings for highly corrosive, high temperature, how pressure, low-temperature, deep-cooling and sanitary conditions.
Upstream
Oil Exploration and production equipment (conditions required: high pressure, sulfur/sand-containing, harsh field environment, high maintenance Frequency).
Exploration and production is the sector with the largest casting demand and most frequent maintenance in the petroleum industry. Core equipment includes drilling, oil production, fracturing equipment. Steel castings are mainly load bearing structural parts, sealing parts and flow-through parts. Maintenance focuses on replacing steel components damaged by wear, erosion, corrosion and fatigue cracking.
Midstream
Oil and Gas gathering, transportation and storage equipment( conditions required: medium-low/high pressure, normal/medium temperature, sulfur/water-containing,)
Gathering, transportation and storage connect upstream production and downstream refining. Core equipment includes manifolds, storage tanks, pump stations, and oil-gas pipeline supporting equipment. Castings are mainly connecting parts, sealing parts, storage body, and pump-valve parts.
Downstream
Oil refining and processing equipment(conditions required: high temperature and pressure, strong corrosion, multi-medium mixture(acid/alkali/hydrocarbon), high precision and corrosion/high-temperature resistance.
Refining and processing is the sector with the highest precision requirements for castings n the petroleum industry. Core equipment includes reaction, distillation, separation and heating equipment. Castings are mainly precision sealing parts, high temperature load-bearing parts and strong corrosion resistant flow through parts.
