T-T Flow® Supplies Air Valves for Major Wastewater Pipeline in Dubai

Air management within pipelines is essential for optimal operation. Air entrapment can lead to significant issues such as water hammer, pipeline failure, flow rate reduction, corrosion, and increased energy costs. Since water naturally contains approximately 2% dissolved air, along with turbulence-inducing pipeline components, air within pipelines is inevitable. Correctly sized and positioned air valves are crucial to preventing costly pipeline failures.

T-T Flow® recently dispatched a number of double orifice air valves for a major new wastewater pipeline currently being constructed by a specialist pipeline contractor in Dubai.

Client Requirements

The contract was secured due to T-T Flow®'s ability to meet the demanding performance requirements, material specifications, and short delivery period. The air valves supplied ranged in size from DN80 to DN200, manufactured in durable fusion-bonded epoxy-coated ductile iron with corrosion-resistant stainless steel internals. They also featured an innovative engineered integral surge alleviation mechanism, eliminating the need for an external check valve that could otherwise reduce performance.

Quality Assurance and Testing

Prior to dispatch, the valves underwent rigorous inspection and a full hydrostatic pressure test, witnessed by a third-party specialist appointed by the client. These tests were conducted using T-T Flow®'s specialist calibrated in-house valve testing facilities at its Cheshire-based headquarters - learn more about our quality assurance. 

Results and Impact

The successful supply of these air valves ensured the project's pipeline system would operate efficiently with reduced risk of air entrapment-related failures. T-T Flow®'s ability to provide high-quality, rigorously tested valves on a short lead time further cemented its reputation as a trusted supplier in international infrastructure projects.

In addition to air valves for wastewater applications, T-T Flow® stocks a vast range of Aquabrake® air valves for potable applications, all of which have WRAS approval. These are available in both single and double orifice configurations, with stainless steel options for arduous applications up to 64 bar.
