Custom-made 5900×18 Carbon Steel Spherical Tank Head (Low-Temperature Pressure-Bearing Type)
Designed for deep, low-temperature working conditions, it relies on 16MnDR material's low-temperature performance and spherical structure, serving petrochemical, coal chemical, and other fields and providing safe solutions for deep, low-temperature medium storage.
1. Core Parameters
Nominal Diameter: 5900mm, suitable for small and medium-sized deep low-temperature storage, balancing capacity and space;
Tank Wall Thickness: 18mm, bearable pressure 1.6~2.5MPa, meeting deep low-temperature liquefied medium storage standards;
Main Material: 16MnDR (GB/T 3531-2014, "R" for low-temperature pressure vessels), Mn 1.3%~1.7%, C ≤0.18%, with trace Nb and V to refine grains; resistant to -40℃~normal temperature, impact absorption energy ≥34J at -40℃, excellent welding performance, anti-brittle fracture and sealing.
2. Core Advantages
Deep Low-Temperature Adaptation: Stable toughness at -40℃, suitable for liquid oxygen (-183℃), liquid nitrogen (-196℃), liquid ammonia (-33℃), etc., with corresponding insulation layers required;
Safety & Reliability: Wall thickness matches pressure, spherical structure bears force evenly (stress concentration factor is 1/3 of cylindrical tank); anti-low-temperature stress corrosion, reducing risks;
Wide Scenarios: Covers petrochemical LPG storage, coal-chemical low-temperature process buffering, industrial gas storage, and new-energy low-temperature energy storage & hydrogen transfer (insulation layers required).
3. Application Fields
Petrochemical: Deep low-temperature temporary storage of LPG, ethane (-88.6℃), ethylene (-103.7℃) (insulation layers required);
Coal Chemical: Buffering & storage of rich methanol liquid (-35℃~-40℃) in low-temperature methanol washing, mixed gas (-196℃) in liquid nitrogen washing (insulation layers required);
Industrial Gas: Storage of liquid oxygen, liquid nitrogen, and liquid argon, suitable for mechanical processing, medical treatment, and electronic chip manufacturing;
New Energy: Liquid CO₂ energy storage (-56.6℃), liquid hydrogen transfer in hydrogen refuelling stations (-253℃) (corresponding insulation layers required).
