Because of this, pressure calculations are easier to perform because the weld quality is taken out of the equation. Another advantage to using seamless steel pipe is its strength under loading. Empty pipe has a certain weight that must be supported over long spans. When that pipe begins transporting material, the weight of the material must also be taken into account. Seamless steel pipe has strength benefits compared with welded pipe. Most pipe failures and leaks take place at the welded seam.
