| Products | Production Capacity | ZHONGDA's Advantages | 
| Internals | 1800T/Year | 1. Use CAD,3-D software to issue drawing,can transfer the requirements clearly. | 
| 2. Can design & fabricate different type of distributor/collects,such as Trough style,Integrated style, Annular style based on clients' requirements. | 
| 3. High accuracy. For distributor/collector with OD=5M, total levelness can be controlled within 3mm. Punch holes tolerence can be controlled within +/-0.03mm for OD≤5mm; and +/-0.05mm for OD>5mm. | 
| 4. Can do pickled & passivation, MP and EP for products; after EP, the roughness can be Ra.5(0.125um). | 
| 5. Have test center, can do column simulation test, to collect data and analyze its' working efficiency. | 
| 6. Can do Oxygen cleaning, thus can supply to air-separation project, except petro-chemical and chemical projects. |
