Abstract
Polly-pigs technique was developed to remove internal rusts and scales from service pipes in the building by using Polly-pigs that were used as various applications in conventional plant pipelines. Results of cleaning experiments on 15mm GSP(Galvanic Steel Pipe) showed that hydraulic cross sectional area was more increased from 3.5% to 15.4% for straight part or elbow parts of several test pieces. Results of optical analysis also showed that rust and scale removed mostly by KDP series(only consisted of Polyurethane) were outside red colored scale (
본 연구에서는 기존 배관설비 분야에서 다양한 용도로 사용되고 있는 Polly-Pigs를 이용한 건물내 급수관의 스케일을 제거하기 위한 공법을 개발하여 이를 평가하였다. 15mm 노후관의 세관실험결과, KDP series에 의해서 직관부 또는 곡관부의 통수능은 3.5~15.4%까지 증가되는 것으로 나타났으며, 육안분석결과 대부분 제거가 이루어진 부분은 적색 스케일(
