Why use TP316 stainless steel pipe in seafood processing?
TP316 stainless steel pipe offers superior resistance to chloride corrosion, making it ideal for seafood processing environments where saltwater exposure is common. It ensures hygienic performance, long service life, and compliance with food-grade standards.
Project Overview
In 2024, a major seafood exporter in Vietnam initiated an upgrade of its processing facility to meet growing international demand, especially from Europe and North America.
Due to the highly corrosive processing environment (saltwater, cleaning chemicals, humidity), the client required a high-performance stainless steel pipe system capable of maintaining:
Long-term corrosion resistance
Food-grade hygiene standards
Stable operation under high-frequency cleaning
The project required 150 tons of ASTM A312 TP316 stainless steel welded pipes, mainly used in seafood washing, processing, and cold-chain transport systems.

Core Pain Points
1. Severe Chloride Corrosion
Seafood processing environments contain:
Saltwater (high Cl⁻ concentration)
Marine atmosphere
Continuous moisture exposure
⚠️ Problem:
Standard TP304 stainless steel would suffer pitting corrosion and rusting.
2. Strict Food Hygiene Requirements
The client needed food grade stainless steel pipe that ensures:
No contamination risk
Smooth internal surface
Easy cleaning and sterilization
3. High-Frequency Cleaning (CIP System)
Pipes were exposed to:
Acidic cleaning solutions
Alkaline detergents
High-temperature water
⚠️ Result:
Low-grade materials would degrade rapidly.
4. Long-Term Cost Control
Frequent pipe replacement would:
Increase maintenance cost
Interrupt production
Reduce efficiency
