Stainless Steel and Duplex Steel Seamless Tubes

 

Aircraft Materials offers the manufacture of seamless pipe for the processing industries where critical services require both mechanical performance and corrosion prevention.The pipe is heat treated in bright annealing furnaces. We export worldwide and our main applications are for condensers, pressure containers, instrumentation, etc. Apart from austenitic stainless steel pipe Aircraft Materials is able to offer the manufacture of ferritic and duplex stainless pipe. We consider flexibility to be an important delivery feature. Small or large quantities can be supplied on a quick delivery schedule.
