They come in individual lengths or continuous length. The welding process removes any extraneous material.<\/p>\n<p>The manufacturing process involves either basic-oxygen or electric-furnace procedures, ensuring the highest quality.<\/p>\n<p>For Grade B pipes, they heat-treat the weld seam after welding.

To set it apart from other pipes and to make maintenance and inspection easier, some makers and users choose to identify ASTM A135 pipe.<\/p>\n<p>The red identifier helps engineers and builders.
