Medium and design conditions
Capacity, design pressure, design temperature, corrosion allowance and service environment must be defined by design documents; the equipment name alone is not a sufficient fabrication basis.
AMMONIA STORAGE TANK
Ammonia Storage Tank
Pressure-vessel fabrication for ammonia storage and related chemical or industrial refrigeration projects, assessed from approved drawings, data sheets, specifications and project quality requirements.
- Ammonia storage
- Build to drawing
- Chemical projects
- Pressure vessels
HEZE HUAWANG manufactures pressure vessels and process equipment against approved project drawings, specifications and applicable codes.
MANUFACTURING SCOPE
Fabrication scope
The following describes assessable manufacturing directions, not unconditional or fixed-rating commitments.- Fabrication to approved drawings
- Assessment of different volumes and design conditions
- Material and welding control
- Heat treatment where required
- NDE and pressure testing
- Large or batch delivery assessment
DESIGN & FABRICATION
Design and fabrication considerations
Materials, structure, inspection and process requirements remain governed by approved project documents and the applicable code.Materials and traceability
Material grade, supply condition, impact requirements and supplementary conditions follow project documents, with identification and traceability maintained through fabrication.
Welding and heat treatment
Welding procedures and heat-treatment requirements are determined from material, thickness, structure and the applicable project specification.
Non-destructive examination
Method, location, extent and acceptance criteria are defined by the design documents, applicable code and project specification.
Pressure testing
Test medium, pressure, procedure and safety controls follow the approved design and fabrication documents before final release.
Connections and accessories
Nozzle orientation, flange standard, level and safety accessory connections and supports are confirmed before fabrication.
Transport and site interface
Large vessels require early review of transport envelope, centre of gravity, lifting points, route and site lifting conditions.

FAQ
Frequently asked questions
01Are complete drawings required for an RFQ?＋
Approved drawings, a data sheet or a specification can be submitted directly. If these are incomplete, send the medium, volume, design pressure and temperature, material, quantity and required delivery date so that missing inputs can be identified.
02Can Huawang fabricate to customer or engineering-company drawings?＋
Yes. Fabrication is assessed against the confirmed design drawings and project conditions, with the final scope governed by the contract and approved documents.
03Is heat treatment always required?＋
Not solely because the vessel stores ammonia. The requirement depends on material, thickness, structure, welding procedure, design documents and applicable code.
04Can large or batch orders be assessed?＋
Yes. Unit dimensions and weight, quantity, quality plan, production schedule, internal handling and transport conditions are reviewed together.
05Do the photographs represent a fixed ammonia-tank model?＋
No. They are verified Huawang fabrication and delivery scenes. Images whose service medium cannot be confirmed are not presented as proof of a specific ammonia-tank model or rating.
