With every passing day, the world is getting superior and is seeking for a stronger choice for diversified purposes. Double Submerged Arc Welded steel pipes also known as DSAW pipes work best in this direction. These are the vast valiant pipes which are employed for innumerous purposes and have widespread applications in distinct industries.
Double Submerged Arc Welded steel pipes typically come in straight and spiral welded formats and are the perfect option for a variety of applications and a number of tasks. It perfectly protects the steel from infectivity of impurities in the air with its submerged welding process. The construction of these potent pipes involves the performance of both –inside and outside welds.
Manufacturing of DSAW Steel Pipes
Usually, the DSAW steel pipes are designed in very large diameter and to exact outside or inside dimensions. The manufacture or construction of the Spiral Welded steel pipe is a bit different. It is the outcome of the difference in the manufacturing process that upshots in a Spiral Double Submerged Arc Welded seam the length of the pipe to lengths of 150 feet (approx.).
The raw materials needed for the formation of DSAW pipes include strip volume, the welding wire and flux. Manufacturing of DSAW steel pipe engrosses first creation of steel plates into the cylindrical shapes. Post the process –the ends of the rolled platter are formed in order to form the V-shaped grooves on the interior as well as exterior surfaces at the location of the seam. Prior to molding, strip is through flattening, trimming, edge planing, transportation and to the curved side surface cleaning etc. is done. Thereafter, the pipe seam is welded by a solitary pass of an arc welder on both the surfaces –interior and exterior and the welding arc is made to be submerged under flux.
Widespread Applications
The leading application of the Double Submerged Arc Welded (DSAW) pipes is in the creation of long distance pipelines dedicated for combustible liquids or / and gases, heating system pipelines, general purpose pipelines, instrumental engineering, mechanical engineering and nuclear station pipelines.
It’s variety in shapes makes it capable of being used for indifferent purposes. Some of the pre-eminent fields (industries) which use the DSAW steel pipes in huge amounts are:
• Oil Industry
• Gas Industry
• Refrigeration Industry
• Refining Industry
• Filtration Industry
• Offshore Industry
• Petrochemical Industry
