종래의 화력 발전소 슬러리 이송관은 금속제 파이프를 사용하기 때문에 내구성이 합성수지제 이송관보다 높은 장점이 있으나 가격이 고가로 되는 불편이 있고, 또 슬러리에 함유된 화학적 성분과 열기를 식히기 위하여 사용하는 냉각수로 바닷물을 사용하기 때문에 염분에 의하여 부식이 빨리 진행되므로 교체주기가 빨라 가격에 비해 사용수명이 길지 않은 불편이 있었다.
Since the conventional thermal power plant slurry transfer pipe uses a metal pipe, the durability of the transfer pipe is higher than that of the synthetic resin transfer pipe. However, there is an inconvenience that the price of the slurry transfer pipe is high and the cooling water used for cooling chemical components and heat contained in the slurry Because of the use of seawater, there is an inconvenience that the corrosion life is not long compared to the price because the corrosion is accelerated by the salt and the replacement cycle is fast.
