Product Overview
The Liquid Ammonia Tank is a low-temperature pressure storage vessel specially designed for liquid ammonia storage and transportation. Due to the alkaline corrosive characteristics and low-temperature requirements of ammonia, the equipment adopts Q345R, 16MnDR low-temperature pressure vessel steel, and 304 stainless steel options.
The tank is designed with a pressure rating of 2.16MPa and an operating pressure of 1.9MPa, suitable for temperatures ranging from -40℃ to 80℃. The cylinder material undergoes dedicated low-temperature toughness testing, while the internal surface receives ammonia-resistant passivation treatment to improve corrosion resistance.
The vessel is manufactured according to pressure vessel standards, with heat-formed heads, hydraulic testing, and gas tightness testing completed before delivery. The designed service life reaches 15~30 years.
Key Advantages
- Low-temperature steel materials provide excellent impact toughness and reduce brittle fracture risks in cold environments.
- Internal anti-corrosion passivation treatment improves long-term ammonia storage reliability.
- Can be equipped with liquid level gauges, ammonia leakage alarms, emergency relief devices, and cooling spray systems.
- Available in capacities from 1~300m³ for both fixed installation and mobile storage applications.
Applications
- Fertilizer and chemical industries
- Industrial refrigeration systems
- Pharmaceutical synthesis
- Metallurgical denitrification
- Ammonia-based desulfurization projects
- Livestock ammonia storage systems
- Chemical raw material storage
Compliance & Delivery Advantages
As ammonia is classified as a hazardous chemical medium, the company provides complete compliance documentation with every unit, including material certificates, low-temperature impact test reports, non-destructive inspection records, strength calculation documents, safety valve and pressure gauge calibration certificates, and equipment registration documents.
The production process supports third-party inspection and supervision. Professional engineers can provide installation guidance for fire protection, explosion prevention, and spray cooling systems.
The equipment includes a one-year warranty, two-hour technical response, and on-site service support within 24 hours when required.
