TUBE FOR FLUID CONDUCTION
APPLICATIONS
Tubes for carrying fluids, gases, petroleum products and other purposes. Used as conductors of solid, liquid, pasty and gaseous materials. Very common in hydraulic and industrial installations, water, gas, compressed air and fire fighting networks.
A106 / API 5L
Carbon steel pipes for use at high temperature.
NBR 5590 – A53
Carbon steel pipe, with quality requirements, for fluid conduction.
NBR 6321
Carbon steel pipe for conducting fluids at high temperatures.
A333
Carbon steel pipe for low temperature use.
