Seamless pipe is made from solid circular billets and has no joints or welding. To produce a seamless pipe, molten metal is forced through a round die with a plug in the center, creating a long tube of continuous metal that is then cut into the required lengths, typically 21 or 40 feet, but various sizes are also available. Sizes ranging from 1/8 inch to 26 inch OD of seamless pipe are fabricated to dimensions and wall thickness specifications. For high-pressure systems, seamless pipe is frequently chosen over weld pipe because it can generally sustain higher operating pressures and temperatures.
