[미국] FAA, 공항 수분 수집과 처리 위해 폴리프로필렌 파이프 승인

연방항공청(FAA)가 민간공항에서 지하수 수집과 처리를 위해 공식적으로 폴리프로필렌(PP) 파이프를 승인했다고 최근 발표했다. PP 파이프가 다른 물질을 대체하는 것을 승인한 이 결정은 설계 엔지니어들과 계약자들이 활주로 아래의 수분을 모으고 제거하는 데 있어서 가볍고 비용 효율적이며 내구성있는 솔루션으로 대체할 수 있게 한다.

FAA approves polypropylene pipe for airport water collection, disposal
    
The Federal Aviation Administration (FAA) recently announced that it has officially approved polypropylene (PP) pipe for subsurface water collection and disposal at civilian airports.

The decision to recognize PP pipe as an equal alternative to other materials enables design engineers and contractors to leverage the benefits of the lightweight, cost-effective and durable solution for water collection and removal under airfield pavements.

 
This updated standard follows the recent approval of high-density polyethylene (HDPE) pipe for under pavement use in all airport areas including deicing pads, runways and taxiways.

Advanced Drainage Systems, Inc. (ADS) (NYSE: WMS), a global manufacturer of water management products and solutions for commercial, residential, infrastructure and agricultural applications, has announced its support of FAA's recent decision.

"This update to the FAA policy is in line with a growing number of Departments of Transportation across the country who have approved [PP] and HDPE pipe for critical infrastructure needs," said Greg Bohn, director of National Engineering and Product Development for ADS.

"These are easy to install, lightweight and cost-effective solutions with a high degree of stiffness and strength," he said, "which enable developers to maximize a project's budget and provide substantial alternatives that meet AASHTO and ASTM standards."

ADS's solutions are used extensively for water management at airports everywhere, including the busiest airport in the world, Atlanta's Hartsfield-Jackson International Airport. The company manufacturers both PP and HDPE pipe in diameters up to 60 inches.
