WELDED STEEL PIPES:-
These high performance pipes and tubes are alloyed with higher contents of moly benumbs and nitrogen to improve the corrosion resistance and the strength are welded with over alloyed filler metals with nitrogen added to the shielding gas to become as high pitting ,corrosion resistance as possible in in the welding. Pipes made of nitrogen alloyed chloride resistance grades in the presented applications are welded with the addition of nitrogen in the shielding gas. Most of pipes are also with filter metal and heat treated when specified
Depending a how and where the pipes will be used it’s up to the end user to decide which type of heat treatment is necessary. Chloride enrichments give however, a risk for pitting, stress, corrosion for standard steel. The pipes are used all types of corrosive enticements in industries such as, chemical, metallurgical energy oil and gas ,pulp and paper , ships ,desalination and fast design properties and higher corrosion resistance other than conventional steel pipes.. These pipes are also used in number of applications where high demands are set as reliability, strength and corrosion resistance.
