High-density polyethylene (HDPE) is an extremely versatile material that is utilized for a number of engineering works.
As one of the most versatile plastic materials around, HDPE plastic is used in a wide variety of applications, including plastic bottles, milk jugs, shampoo bottles, bleach bottles, cutting boards, and piping. Known for its outstanding tensile strength and large strength-to-ensity ratio, HDPE plastic has a high-impact resistance and melting point.

저의 경우, 주로 물배관으로 사용되는 배관라인과 Tank 주변 Dike 내부 바닥에 지반침투방지용으로 접했습니다.
대부분 열을 가해서 접합해야 하며 다루기가 용이하죠!! 전원선 상태 확인 및 다림질과 같은 작업방법의 경우는 화상 상해에 주의해서 작업해야 할 것 입니다.
HDPE도 지중매설된 것들이 많습니다. 터파기할 때 조심하셔야 합니다.
제가 근무한 현장은 물배관을 너무 많이 터트려서 물바다 많이 되었습니다 ^^;;;;
