High Flow Circulation Loop Testing Services
Boost your product development with comprehensive pipe testing that goes beyond standard hydrostatic test methods. Our high-flow circulation loop testing services deliver real-world performance data by simulating actual usage conditions, providing a more comprehensive evaluation compared to traditional hydrostatic pressure testing, so that you can validate your designs faster and more efficiently. Our independent, reliable test data gives you confidence in your product.

What is High Flow Circulation Loop Testing at Element?
High-flow circulation loop testing simulates end-use conditions for water pipes by using flowing water containing dissolved oxygen under controlled temperature and pressure. At Element, we provide experimental testing to evaluate how pipe life expectancy is affected by bend radius, fittings, and insulation, delivering more comprehensive data than traditional static water tests.

Frequently asked questions
How does high-flow circulation testing differ from standard hydrostatic testing?
Our service uses flowing water containing dissolved oxygen to simulate dynamic, real-world conditions such as turbulence and oxygen interaction with pipe materials, whereas traditional hydrostatic testing uses stagnant water, providing only basic pressure data and limited insights into long-term performance.
Can you introduce fresh water during testing?
Yes, fresh water can be introduced at predetermined ratios to simulate specific end-use situations, giving you more accurate real-world performance data for your products.
