Abstract

본 발명은 콘크리트 펌프카에서 콘크리트 슬러리 이송시 자갈이나 모래와의 마찰에 대한 내마모 특성을 가지며, 또한 내충격성도 우수한 콘크리트 펌프카용 콘크리트 슬러리 이송 파이프에 관한 것이다. 본 발명에 따른 콘크리트 펌프카용 콘크리트 슬러리 이송 파이프는 탄소강으로 이루어진 강재 파이프로서, 상기 파이프 외측 또는 내측 일부에서 상기 파이프가 유도 가열되고, 상기 파이프 내,외측에서 가열된 부분이 냉각되어 경화됨으로써 경도가 hv450 이상으로 형성되는 열처리부; 및 상기 열처리부와 인접하는 비열처리부;를 포함하고, 상기 열처리부 및 상기 비열처리부는 상기 파이프의 길이를 따라서 나선형 띠 형태로 연속되게 배치되고, 상기 열처리부의 폭이 상기 비열처리부의 폭보다 더 큰 것을 특징으로 한다.
