Would like to ask about the plastic lined steel pipe, steel pipe, glass steel skeleton, the advantages and disadvantages of each ceramic pipe, to know a friend told, very grateful!
Plastic lined steel pipe of strong corrosion resistance, heavy quality, need to be made, on-site installation, if the size deviation cannot be installed. The price is more than 5 times more expensive than that of FRP
FRP corrosion resistance, high strength (afraid of tanks), light quality, easy to install, socket or flange interface, the price is more expensive than cement
Steel skeleton pipe is not corrosion resistant, often used in drainage, easy to install, the price is almost the same as fiberglass, cheap inside there is no steel skeleton
