Helically submerged arc welded (HSAW) pipe is a type of steel pipe produced using a welding process where the steel strip is formed into a pipe shape and then welded along a helical seam. The submerged arc welding technique involves feeding a granular flux over the weld area, which protects the molten weld pool from contamination and improves the quality of the weld. HSAW pipes are commonly used in various applications, including oil and gas transportation, water supply, and structural applications, due to their strength and durability. Their manufacturing process allows for the production of large-diameter pipes at high speeds.
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
To calculate the degree of a bend, you can use the formula: Degree of Bend = (Arc Length / Radius) × (180/π). Measure the arc length of the bend and the radius of the bend. Then, plug these values into the formula to obtain the degree of the bend in degrees. This method is commonly used in fields like metalworking and pipe fitting.
Arc measure is the number of radians. Two similar arcs could have the same arc measure. Arc length is particular to the individual arc. One must consider the radius of the arc in question then multiply the arc measure (in radians) times the radius to get the length.
To calculate the arc length in an electric arc furnace, you can use the formula: ( L = \theta \times r ), where ( L ) is the arc length, ( \theta ) is the angle in radians, and ( r ) is the radius of the arc. First, determine the angle that the arc subtends at the center of the furnace, then measure the effective radius from the arc's origin to the point where the arc terminates. Multiply these values to find the arc length.

Helically Submerged Arc Welded
No. Double Submerged Arc Welded is DSAW; LSAW stands for Longitudinal Submerged Arc Welded. As an aside, HSAW stands for Helically Submerged Arc Welded. All of these refer to various types of pipe manufacturing processes.
Double submerged arc welded pipes has two types, one is spiral welded pipes, and the other is longitudinal welded pipes which are different from EFW pipes.
This acronym means Helical Submerged Arc Welded pipes. They are also know as Spiral Submerged Arc Welded pipes. These specification of pipes are assembled via welding. They are mainly deployed for the transportation of oil and gas in some cases, water. Hope this helps.
Double Sub-merged Arc Welding usually associated with spiral welded pipe. The welding arc is submerged in flux to protect from air impurities, this process is done on both the id and od seperately hence double submerged.
SAW PIPE = SUB MERGED ARC WELDED PIEP
L- SAW stands for Longitudinal Sub Merged Arc Welded Pipe.here the pipe are produced by welding a plate longitudinaly. i.e the welded seam will be longitudinal. these types of pipes are basicaly used for non critical lines.

What are the basic mechanical testing methods for arc welded joints?
Submerged arc welding is called "submerged" because the high voltage electrical current (called the "arc") that heats the metal and wire to weld together is submerged underneath layers of granular earth materials called "flux". About 50% to 90% of this flux can be re-used and fed back into the system with the proper equipment.
