ASTM A789 S31803 S32205 Heat Exchanger U Tubing , Duplex Steel U Bend Tube

Duplex Steel Tube:

Due to the characteristics of the two-phase organization, the duplex stainless steel has the advantages of both ferritic stainless steel and austenitic stainless steel by properly controlling the chemical composition and heat-treatment process.

It combines the excellent toughness and weldability of austenitic stainless steel with the higher strength and chloride stress corrosion resistance of ferritic stainless steel, and it is these superior properties that make duplex stainless steel develop rapidly as a weldable structural material

Heat Exchanger U Tube Advantage:

Superior surface finish

Better mechanical property

More precise dimension ;

Perfect inspection method and inspection equipment

Duplex Heat Exchanger Tube Application :

Boiler tube applies to petroleum , chemical industry , electric power , boiler , high temperature resistant , low temperature resistant , corrosion resistant . The size can be made according to the customers requirements . High pressure boiler pipe applies to container , petrochemical and so on . Note : Generally , high pressure boiler pipe’s working pressure above 9.88Mpa and working temperature between 450 to 650 .

MTSCO heat exchanger tube with pickling and annealing surface is very popular in boilers and heat exchangers industry , water heater industry , air-conditioning industry etc . This kind of seamless tubes are have a very important position in our all products .
