Core Pain Points
1. Strict Hygiene Requirements 🧼
Central kitchens require ultra-clean environments:
No bacterial growth allowed
Easy cleaning systems required
Zero contamination risk
⚠️ Problem:
Standard industrial pipes cannot meet food-grade hygiene standards.
2. Chemical Cleaning Corrosion Risk
Daily operations involve:
Alkaline cleaning agents
High-pressure CIP cleaning systems
Disinfection chemicals
👉 Low-grade pipes corrode quickly under chemical exposure.
3. Continuous 24/7 Food Production
Large meal preparation volume
No downtime allowed
System reliability is critical
4. Singapore Food Safety Compliance 🇸🇬
Strict compliance requirements:
NEA food hygiene regulations
HACCP system integration
International export-grade standards
Our Solution
✔ 1. Dual Standard Food Grade System (ASTM A270 + A312)
We provided a hybrid hygienic piping solution:
ASTM A270 → hygienic tubing (food contact surface)
ASTM A312 → structural pipeline system
👉 Ensures both hygiene + structural strength
✔ 2. Mirror Polished Internal Surface (Ra ≤ 0.8μm)
Key upgrade for central kitchen use:
Ultra-smooth inner wall
Prevents bacterial adhesion
Easy CIP cleaning
✔ 3. TP316L Corrosion Resistant Upgrade
For high-end hygiene systems:
Better resistance to chloride corrosion
Suitable for chemical cleaning cycles
Longer service life
✔ 4. Full Hygienic Welding System
Orbital welding support
No dead corners design
Leak-proof pipeline structure
✔ 5. Strict Quality Inspection
Surface roughness testing
Hydrostatic pressure test
Weld inspection (X-ray optional)
Food-grade certification compliance
Application in Central Kitchen System
Food Preparation Line
Ingredient mixing and processing pipelines
Cooking System
High-temperature liquid transfer systems
Cleaning (CIP System)
Automated hygiene cleaning pipelines
Distribution System
Food transfer to packaging and storage areas
Project Results
