Stainless Steel Welded Pipe

What is stainless steel ERW pipe?

A stainless steel welded pipe is cold rolled flat strip or sheet and then made circular using a bending machine. Stainless steel ERW pipe can be welded with or without filler material utilizing a high source of energy. These pipes can be produced in customize sizes without any restrictions. The SS welded pipe can work well in moderate corrosive environments due to the presence of welds. The economically welded stainless steel pipe is simpler to procure and produce. These ERW pipes have a good surface quality and have a consistent wall thickness. Stainless steel welded round pipes are used in the transportation of water, oil, and gas in larger quantities.

How to check the seam of a welded stainless steel pipe?

The seam of the A312 welded pipe can be inspected based on different factors. The ERW pipes can be checked with appearance tests, surface non-destructive testing, and ray detection or ultrasonic detection tests.

How do you calculate maximum allowable working pressure of stainless steel ERW pipe?

A spiral wound stainless steel pipe can calculate the maximum allowable pressure using this formula P=2St/D.

Here, P= pressure of the ERW material
t=nominal wall thickness
D= outside diameter in inches
S= allowable stress in psi

Why Ultrasonic, Radiography & Magnetic particle test performed for Stainless Steel ERW Pipe?

The three tests are performed on a large diameter stainless steel welded pipe to detect any flaws or defects in the material. Ultrasonic tests use sound waves to measure their thickness. Radiography tests use x-rays or gamma rays to identify flaws in the system. Magnetic tests are very sensitive that ensure the finest defects are detected.

Difference between Stainless Steel Spiral Welded Pipe, ERW, SAW, and EFW

A stainless steel spiral welded pipe is produced as coils of steel that are flattened after unwinding. Angled rollers are utilized to flatten a stainless steel ERW pipe. These pipes can be classified into the 3 common specifications, namely ERW, SAW, and EFW.

The Stainless Steel ERW Pipe is a specification that is produced as the material is cold rolled and welded longitudinally. The versatile SS ERW pipe makes use of low voltage current to melt and weld the pipe.

A Stainless steel Efw Pipe has the same forming and production capabilities as ERW pipes. However, they make use of high voltage current to weld the material. The efw stainless steel pipe is an excellent choice for welding it with dissimilar piping systems.

A SAW pipe is produced as an arc is created between the workpiece and the continuously fed electrodes. The SAW stainless steel spiral pipe is protected against weld contamination using a protective gas shield. This allows it to weld material with higher thicknesses.

Why must the ends of stainless steel ERW pipe be bevelled before being welded?

Beveling the ends of the stainless steel ERW pipe creates a V-shaped groove or a J-groove. This groove allows for better access and penetration of the welding arc, resulting in improved weld quality. It ensures a consistent and complete fusion between the pipe ends and the weld metal.

How to calculate SS ERW pipe pressure rating?

Identify the specific grade and type of steel used in the SS ERW pipe to calculate its pressure rating. Determine the allowable stress for the steel material at the operating temperature. The allowable stress accounts for safety factors and is usually expressed as a percentage of the material’s yield strength.

Employ an appropriate formula or equation to calculate the pressure rating of the welded stainless steel pipe. The most widely used formula for calculating the pressure rating of pipes is the Barlow formula. Pressure Rating of stainless steel spiral welded pipe = (2 * Allowable Stress * Wall Thickness) / (Outside Diameter – 2 * Wall Thickness).

What is the difference between SS ERW pipe and high frequency welding?

SS ERW pipe is produced by passing an electric current through the edges of a steel strip or coil. HFW is a variation of the ERW process where high-frequency electric currents are used to create heat for welding. ERW welding is generally slower compared to HFW due to the lower frequency of the electric current used.
