Your Project Acceptance Starts with a Trusted Test Report – CNAS Makes It Happen
“Most steel water pipe suppliers provide only factory test reports that local authorities may reject.
Cangluo Group is different. Our CNAS-accredited laboratory (ISO/IEC 17025) issues test reports that are recognized in over 60 countries including the USA, Germany, Japan, and Saudi Arabia.
Each batch of our steel water pipes (especially potable water steel pipe) undergoes:
✔ Coating thickness & adhesion test (FBE/3PE)
✔ Salt spray corrosion test (≥1500 hours, CASS standard)
✔ Chemical composition analysis for drinking water safety
✔ Mechanical properties test (tensile, yield, impact)
“The CNAS report from Cangluo was accepted directly by Dubai Municipality. No re-testing needed. Saved us 3 weeks of approval time.”

Frequently Asked Questions About Steel Water Pipes
Q1: What is the difference between steel water pipes and potable water steel pipes?
A: Steel water pipes is a broad category that includes pipes for irrigation, fire water, cooling water, and other applications. Potable water steel pipe is a subset with special internal coating (FBE/cement lining) and certified testing (CNAS/NSF) to ensure drinking water safety. Cangluo offers both – just tell us your application.
Q2: Can your steel water pipes be used for drinking water projects?
A: Yes. Our potable water steel pipe is specially produced with food-grade FBE coating and comes with a CNAS test report that is accepted by water authorities worldwide. No rust, no odor, no rejection.
Q3: Do you provide CNAS test reports for all steel water pipes?
A: For potable water applications, yes – each batch includes a CNAS report. For irrigation, fire water, or cooling water orders, we provide standard factory test reports, with CNAS reports available upon request (additional charge applies).
Q4: What is the minimum order quantity (MOQ) for steel water pipes?
A: 2-5 tons for standard sizes. For custom specifications, MOQ can be negotiated based on your project requirements.
Q5: How long does delivery take?
A: 7-45 days depending on order quantity and coating requirements. Stock sizes can be shipped within 7 days. Large potable water projects (with CNAS testing) typically require 20-30 days.
Q6: What coatings do you offer for potable water applications?
A: FBE (Fusion Bonded Epoxy) is the standard for drinking water. Cement mortar lining is also available for large-diameter water transmission lines. Both are NSF/ANSI 61 compliant upon request.
