Our 90m³ Liquid Ammonia Storage Tank is engineered and manufactured to meet the highest safety and metallurgical rigor for modern chemical processing, agricultural storage, and industrial refrigeration. Fabricated using pressure-vessel grade Q345R steel and subject to full post-weld stress-relief heat treatment (PWHT), this tank ensures absolute structural integrity under a design pressure of 2.16 MPa.

2. Advanced Nozzle Configuration & Functional Benefits

Liquid Inlet System: Extends deep into the vessel interior with a 45-degree miter cut end. This hydrodynamic design prevents the liquid medium from directly washing against the inner walls, substantially reducing localized erosion and corrosion while eliminating static build-up during rapid filling.
- Flange Spec: HG20592 PL68-1.6 RF 16Mn (Low-alloy seamless steel)
Liquid Outlet System Utilizes a detachable pressurized siphon/submerged pipe assembly. This allows the liquid to be smoothly discharged to higher or parallel process units under internal pressure, ensuring the collection of pure, precipitate-free medium.
- Flange Spec: Shell joint HG20592 PL32-1.6 RF 16Mn (ID 25mm); Terminal HG20592 PL20-1.6 RF 16Mn
Drain / Blowdown Nozzle: Strategically positioned at the absolute bottom of the shell. It allows complete evacuation of residual wash liquids and built-up corrosive sediments during maintenance turnarounds.
- Flange Spec: HG20592 PL50-1.6 RF 16Mn, paired with J41W-16 Globe Valve.
Level Gauge & Vent Nozzles: Configured for dual anti-frost glass tube level gauges (AI2.5-1260-50 HG/T21550-93) to ensure precise inventory verification. The dedicated vent pipe allows rapid displacement of air during initial filling cycles for counter-pressure-free loading.

3. Integrated Safety & Control Accessories (Optional)

To provide a turn-key solution, the tank can be pre-configured with high-integrity instrumentation:

Safety Relief Valves: Dynamically sized according to system relief mass flow rates to prevent over-pressurization.
Magnetic Level Indicators: Highly visible magnetic flaps with optional 4-20mA remote transmission.
Industrial Pressure & Temperature Gauges for real-time control room monitoring.

Why Choose Our Pressure Vessels?

Stress-Relieved Longevity: Full PWHT eliminates residual welding stresses, drastically lowering the risk of Stress Corrosion Cracking (SCC) in ammonia environments.
Precision Manufacturing: Heavy-wall construction (22/24mm) provides a generous corrosion allowance, safely guaranteeing a 15-year operational life.
Traceable Quality: Complete QA documentation, including X-ray radiographic testing reports and hydrostatic test certifications, is provided with every shipment.
