How is seamed pipe created?

1. Welding plate edges together

2. Forging a solid piece of metal

3. Extruding through a die

4. Bending and hammering metal

The correct answer is: Welding plate edges together

Seamed pipe is created by welding the edges of plates together. This process involves taking flat steel plates and shaping them into a cylindrical form, followed by joining the edges through various welding techniques. The result is a pipe with a seam where the edges meet, which gives it strength while allowing for long lengths of piping to be manufactured from smaller, more manageable pieces of material. This method of pipe production is cost-effective and efficient for creating pipes of various diameters and wall thicknesses. Seamed pipes are commonly used in various applications such as construction, plumbing, and industrial processes, where strength and the ability to create long lengths of pipe are critical. Other methods, like forging a solid piece of metal, would produce solid rods or bars instead of hollow pipes; extruding involves forcing material through a shape to create continuous sections, which is not the method used for seamed pipes; and bending and hammering metal apply more to shaping existing pieces rather than creating them.
