Seamless Pipe:Welded Pipe:1:Strength:Able to withstand more pressure and load as there is no weak seam. Due to welding they are believed to withstand 20% less pressure and load as compared to seamless pipe. 2:Length:Relatively shorter in length due to manufacturing difficulties. Can be manufactured in long continuous lengths. 3:Size
Seamless pipes are, on the other hand, a kind of steel pipe in the shape of square or rectangle having no seam around with hollow cross-sections, which is used in conveying liquid as well as making structural and machine parts, thanks to its high anti-bending and anti-torque strength and unbelievable lightness. Cold Drawn Seamless Tubing - CDS Steel Tubing Uniform Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn 1018/1026 steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless.

For example, seamless piping is required for many high-pressure, high-temperature applications in the oil & gas, power generation and pharmaceutical industries. Welded piping (which is generally cheaper to produce and is more widely available) is specified across all industries as long as the temperature, pressure and other service variables do not exceed parameters noted in the applicable standard. Welded vs. seamless steel pipe American Piping ProductsSeamless pipe lacked this perceived structural flaw and was considered safer. While its true that welded pipe does include a seam that makes it theoretically weaker, manufacturing techniques and quality assurance regimens each have improved to the extent that welded pipe will perform as desired when its tolerances arent exceeded.
Seamless pipe was initially formed by drilling a hole through the center of a cylinder. However, it was difficult to drill holes with the precision needed to ensure uniformity in wall thickness. An 1888 improvement allowed for greater efficiency by casting the billet around a fire-proof brick core.
