일반적으로, 폴리에틸렌 파이프는 표면 마찰계수가 낮고 내화학성이 우수하여 음용수와 같은 액체 또는 가스의 이송용으로 사용되는 파이프인 것이다.In general, polyethylene pipes have low surface friction coefficients and excellent chemical resistance, so they are pipes used for transporting liquids or gases such as drinking water.

이상과 같은 폴리에틸렌 파이프는 그 외면에 내구성의 보완을 위하여 보강섬유층을 형성하여 외면 충격에 대한 강도를 높일 수 있도록 적용하여 실시하고 있다.Polyethylene pipes as described above are applied so as to increase the strength against external impact by forming a reinforcing fiber layer on the outer surface of the polyethylene pipe to supplement durability.

또한, 종래 폴리에틸렌 파이프는 그 외면에 난연소재로 이루어진 난연피복층을 형성하여 화재에 대한 대비를 할 수 있도록 적용하여 실시하고 있다.In addition, conventional polyethylene pipes are applied to prepare for fire by forming a flame-retardant coating layer made of a flame-retardant material on the outer surface thereof.

그러나, 상기한 바와 같은 종래 폴리에틸렌 파이프는 난연피복층을 가지고 있어도 화재에 강한 화염에 노출되게 되면 불이 붙게 되는 데 이때 염소가스와 같은 할로겐 족에 속하는 유독성 가스가 발생하고 많은 연기가 발생하여 질식사를 유발하는 문제점이 있었다.However, even if the conventional polyethylene pipe as described above has a flame-retardant coating layer, it catches fire when exposed to a strong flame. At this time, a toxic gas belonging to the halogen group such as chlorine gas is generated and a lot of smoke is generated, causing suffocation. There was a problem.
