ERW Carbon Welded Steel Pipe
What is welded steel pipe?
Welding pipes is one of the simplest and most durable ways to join piping together and steel pipes can simply be welded together with MIG (metal inert gas), TIG (tungsten inert gas or SMAW (stick metal arc) welding. Before welding two pipes together, avoid any gaps between the two pipes. While welding, take measures to ensure the continual alignment of the two pipes.
Welded steel pipe in the form of welds are divided into straight seam welded pipe and spiral welded steel pipe. By production method classification: process classification - arc welded pipe, resistance welded pipe, (high frequency, low frequency) gas welded pipe.
What is Seamless steel pipe?
Seamless piping begins as a solid cylindrical hunk of steel called a billet. While still hot, billets are pierced through the center with a mandrel. The next step is rolling and stretching the hollow billet. The billet is precisely rolled and stretched until it meets the length, diameter and wall thickness as specified by the customer order.
