PVC 급수 파이프 마을 급수 건설 계획: 응력 테스트 및 파이프라인 부동액

2025-08-18

마을 상수도 사업에서

PVC 상수도 파이프는 내식성, 저비용, 설치 용이성 및 기타 장점 때문에 널리 사용됩니다. 그러나 복잡한 지질 조건, 겨울철 저온 및 기타 요인으로 인해 건설은 응력 테스트 및 파이프라인 부동액 링크의 제어에 중점을 두어 장기간 안정적인 상수도 시스템 운영을 보장할 필요가 있습니다. 다음의 기술적 요점, 구현 단계 및 품질 관리는 세 가지 측면을 설명합니다.

먼저 스트레스 테스트 기술 사양

1. 시험 전 준비

파이프라인 설치가 완료된 후 인터페이스가 손상되지 않고 브래킷이 단단하지 않은지 확인하기 위해 외관 검사가 필요합니다. 시험을 위해 깨끗한 물을 사용하고, 수온 테스트 섹션의 길이는 1km를 초과하지 않아야 하며 높이 차이가 큰 영역은 섹션으로 테스트해야 합니다.

2. 등급 부스트 작동

- 사전 테스트 단계: 작동 압력의 1.5배(0.6MPa 이상)로 천천히 부스트하고, 30분 압력 조절 후 인터페이스가 누출되는지 확인합니다.

- 주 테스트 단계: 시험 압력(작업 압력의 1.5배), 1시간 압력 조절 후 압력 강하는 0.05MPa를 초과하지 않아야 하며, 누출이 없도록 외관 검사를 위한 작업 압력으로 감소해야 합니다.

특수 사례 처리

누출 지점이 발견되면 즉시 압력 배수를 줄이고 수리 후 동결 방지 파이프라인 배치 깊이 제어

추운 지역에서는 파이프라인의 매립 깊이가 국소 냉동 토양 두께 0.3m 이상을 초과해야 합니다. 지질 조사를 통해 영구 동토층 데이터를 확인합니다. 예를 들어 동북 평야 지역의 매립 깊이는 1.8m에 도달해야 하며 북중국 지역은 1.2m 이상이어야 합니다.

2. 단열재 선택

- 실외 표면 장착 파이프라인은 두께가 50mm인 고밀도 폴리에틸렌 재킷 파이프(PEF)에 의해 절연되며 인터페이스는 방수 테이프로 밀봉됩니다.

- 밸브 내벽에 50mm 두께의 폴리우레탄 단열판을 붙이고 배수관 바닥의 하이벨은 1177777 수도계량기 유정의 경우 이중층 유정커버+폴리스티렌 폼보드 단열재를 사용하고 내부에는 전기난방장치(전력 20W/m)를 설치한다.

셋째, 품질관리 포인트

1 재료 수용

현장에 진입하는 PVC 파이프는 공장 인증서와 벽 두께 편차(10%), 낙하 중량 충격 테스트(0℃에서 균열이 없는 1kg 무거운 망치 1m 높이 충격) 및 기타 테스트.

시공기록

은 응력시험곡선, 파이프라인 좌표 고도, 단열층 두께 및 기타 데이터를 상세히 기록하여 숨겨진 엔지니어링 승인 문서를 작성한다. 117277777984001 비상지원 용접 장비의

스트레스 테스트 및 동결 방지 프로그램의 과학적 구현을 통해 PVC 파이프라인 시스템의 작동 위험을 효과적으로 줄일 수 있습니다. 엔지니어링 관행에 따르면 위의 기술을 채택한 후 겨울철 파이프라인 고장률을 80% 이상 줄일 수 있으며 누수율을 12% 이내로 제어할 수 있어 마을과 마을의 급수 보증 능력이 크게 향상됩니다.
