Client Profile
Client:
A HACCP & ISO 22000 Certified Dairy Processing Company in Ho Chi Minh City, Vietnam
Industry: Dairy Processing (Milk, Yogurt, UHT Beverages)
Facility Size: 3 Production Lines, Annual Capacity 180,000 Tons
Certification: HACCP / ISO 22000 / Export-Oriented (US & EU Market)
Equipment Reference:
Processing systems aligned with international standards used by companies such as Tetra Pak and Alfa Laval
Project Background
In 2024, the client expanded its dairy production facility to meet increasing export demand from North America and Europe. The upgrade required a complete hygienic piping system for:
Milk processing lines
CIP (Clean-in-Place) systems
Sterilized liquid transport
Purified water pipelines
Due to strict export compliance, the client needed a reliable stainless steel pipe supplier capable of delivering food grade stainless steel pipe that meets international hygiene and corrosion resistance standards.

Core Pain Points
1. Food Safety Compliance Pressure
The client needed to pass strict audits from:
U.S. FDA food safety inspections
EU food-grade material requirements
Third-party certification bodies
⚠️ Risk:
Any contamination from piping systems could lead to export rejection or product recalls.
2. Ultra-Clean Internal Surface Requirement
Dairy products are highly sensitive to contamination. The client required:
Low surface roughness (Ra ≤ 0.8 μm)
No welding slag or oxide scale
Anti-bacterial surface condition
3. High-Frequency CIP Cleaning Environment
The piping system had to withstand:
High-temperature steam sterilization
Acidic and alkaline cleaning agents
Daily cleaning cycles
⚠️ Standard carbon steel or low-grade stainless steel would fail quickly.
4. Project Deadline Pressure
Equipment installation already scheduled
Pipeline system must arrive within 3 weeks
Delay = production loss
Our Solution
