Welded Steel Tubes
Welded
steel tubes and tube are used in a number of applications where high demands
are set on reliability, strength and corrosion resistance. These high performance
tubes and tube are alloyed with higher contents of molybdenum and nitrogen in
order to improve the corrosion resistance and the strength, and are welded with
over alloyed filler metals and/or with nitrogen added to the shielding gas,
in order to become as high pitting corrosion resistance as possible in the weld.
tubes made of nitrogen alloyed chloride resistant grades in the presented applications
are welded with the addition of nitrogen in the shielding gas. Most of the tubes
are also welded with filler metal and heat treated when specified. Welded steel
tubes and tubing come in improved design properties and are much higher corrosion
resistance than other conventional steel tubes.
Depending on how and where the tubes will be used it is up to the end user to
decide which type of heat treatment is necessary. Chloride environments give
however a risk for pitting, crevice and stress corrosion for standard steels.
The tubes are used in all types of corrosive environments in industries such
as, chemical, metallurgical, energy, oil & gas, pulp & paper, ships,
desalination, and food.
