Professionally Manufacture Maintenance, Inspection T21 Un Protable Metal Alkyls Catalyst Tanks Distributed Globally
Professional Manufacturing: Produced in strict accordance with international dangerous goods transportation container standards (such as IMDG Code, ISO standards), with high-quality Aluminium Metal Alkyls materials ensuring excellent corrosion resistance and structural stability, suitable for the storage and transportation of TEA、 TMA、MAO ,TEOS and other similar flammable liquids.
Global Circulation Compliance: The design and manufacturing meet the requirements of various international transportation modes (maritime, land, air), with complete certification documents, enabling smooth circulation across global markets.
Comprehensive Remanufacturing Services: Return to Kunshi Keystone Vessel for one-stop remanufacturing, including detailed maintenance (repair of damaged components, replacement of seals, etc.), strict inspection (pressure test, leak test, material performance test, etc.), and professional internal treatment (cleaning, passivation, drying, etc.) to restore the tank container's performance to meet safe use standards.
Service Value: Extending the service life of tank containers through professional remanufacturing not only improves the utilization rate of equipment but also reduces the environmental impact caused by waste tank disposal, achieving economic and environmental benefits.
Provide comprehensive maintenance services in manufacturing (tank inspection, repair, re-spraying), thereby extending the service life of customer products
