Super Duplex Steel Pipes
Super Duplex Steel pipes are made using a mixture of austenitic and ferritic steels. These pipes are specifically developed for use in Oil & Gas industries. SD pipes are known for their superior corrosion resistance.
The difference when comparing super duplex and duplex steel pipes is the higher molybdenum and chromium content in the former. The well balanced dual-phased structure helps in giving these pipes a combination of strength and corrosion resistance. To make these steel pipes more cost effective, these are alloyed with nickel and molybdenum in lower amounts. Chloride environmen
