Abstract

본 발명은 서로 연결되는 다수의 개변 배관 절편부로 구성된 원격열 이송용 배관 시스템에 관한 것이다.The present invention relates to a piping system for remote heat transfer consisting of a plurality of modified pipe segments connected to each other.

각각의 개별 배관 절편부는 파형의 금속 내측관, 파형의 금속 외측관, 내측관과 외측관 사이에 배치되고 특정 반응 데이타에 의해 화학적으로 추진되는 폴리우레탄 포말로 형성된 열절연층 및 외측관상에 배치되는 플라스틱 외피로 구성된다. 외측관은 플라스틱 외피와 결합하여 매설시에 예상되는 지반하중 및 교통하중이 전적으로 이들 양 부재에 흡수되도륵 형성된다. 이러한 배관 시스템은 폴리우레탄 포말의 체적이 작업 응력에서 내측관과 외측관 사이의 링형 공간의 체적의 80% 이하로 떨어지지 않도록 구성된다.Each individual pipe segment is disposed on the corrugated metal inner tube, the corrugated metal outer tube, the thermal insulation layer formed between the inner tube and the outer tube and formed of a polyurethane foam chemically propelled by specific reaction data and the outer tube. It consists of a plastic sheath. The outer tube is combined with the plastic shell so that the ground and traffic loads expected at the time of embedding are completely absorbed by both members. This piping system is configured such that the volume of the polyurethane foam does not drop below 80% of the volume of the ring-shaped space between the inner and outer tubes at working stress.
