How Rolled and Welded Steel Pipes Are Manufactured

People have used pipes for thousands of years. Perhaps the first use was by ancient agriculturalists who diverted water from streams and rivers into their fields. Archeological evidence suggests that the Chinese used reed pipe for transporting water to desired locations as early as 2000 B.C. [1] Today, there are various types of steel pipes, such as rolled and welded steel pipes. These are used when the diameter and/or wall thickness requires something other than a standard mill product.

Step 1: Confirming Welded Steel Pipe Details

R and W steel pipes are one of the oldest processes of manufacturing steel pipe. Prior to rolled and welded pipe fabrication, we have our client review our R and W steel pipe details before we procure the materials and start the fabrication.

Step 2: Rolled and Welded Pipe Fabrication

After this information has been verified and approved by the client, rolled and welded pipe fabrication begins. The large diameter steel pipe is cut according to client specifications and then the edges are beveled and prepped for welding. Forming is the next step in the rolled and welded pipe fabrication to produce a cylindrical pipe. Welding of the large diameter fabricated steel pipe is the last step before it reaches our in-house quality control team.

Step 3: Certification of Rolled and Welded Steel Pipe

Rolled and welded pipe fabrications are inspected by our Quality Assurance team, Certified Welding Inspectors, and/or Third-party Inspection as our clients’ specifications may require.

Step 4: Delivery of The Rolled and Welded Steel Pipe

After inspection and any of our clients’ required testing, we then blast, coat, passivate, and ship your large diameter steel pipe to your facility anywhere in the continental U.S. or overseas.
