Mills produce two types of line pipe, seamless and welded

Seamless pipe is formed from a cylindrical bar of steel. The bar is heated to a high temperature and then a probe is inserted to create a hole through the cylinder. The cylinder is then transferred to rollers which size the cylinder to the specified diameter and wall thickness. A few mills can produce seamless pipe up to 24-in in diameter. For small diameter pipe, seamless pipe is common.
