Chengrong Ultrafiltration Water Purifiers: Every Drop Guarded by Food-Grade 304 Stainless Steel
(Serial No. 012)
In the world of water purification, material choice is the cornerstone of quality – and at Chengrong Ultrafiltration, we’ve built our reputation on food-grade 304 stainless steel (SS304). This isn’t just metal; it’s a pledge to safeguard your family’s health with every sip.
SS304: The Food-Safe Guardian
Widely trusted in food and beverage industries, SS304 is the gold standard for corrosion resistance, stability, and safety. Every pipe, joint, and critical component in Chengrong Ultrafiltration systems is crafted from this premium alloy. Why? To ensure water purity from source to tap – no compromises, no contamination.
Triple-Layer Quality Defense
In a market flooded with counterfeits, how do we guarantee authenticity? Chengrong’s answer: rigor, relationships, and relentless testing.
1.Precision Screening
Every raw material batch undergoes strict checks by our Incoming Quality Control (IQC) team:
lDimensional Accuracy: Pipes must meet exact diameter (e.g., 159mm nominal) and thickness tolerances.
lMaterial Integrity: Spot testing with chemical reagents and 72-hour salt spray trials simulate extreme conditions to verify corrosion resistance.

2.Trusted Partnerships
Our decade-long collaboration with core suppliers is a story of mutual growth. Early struggles (think rejected batches and endless revisions) forged unshakable trust. Today, these suppliers are industry leaders – a testament to shared values and grit.
3.Random Audits, Reliable Results
Monthly unannounced material audits focus on critical elements like chromium (Cr) and nickel (Ni) content. Only fully compliant SS304 makes the cut.
