The difference between 316 Seamless and welded pipe

The 316 grade stainless steel, like ASTM A312 TP 304, incorporates chromium and nickel for enhanced corrosion resistance. Moreover, SS 316 Pipe contains molybdenum, further bolstering its corrosion resistance.

In terms of manufacturing, there are two primary methods utilized for shaping pipes from this material. Firstly, seamless pipes are crafted through a process known as cold drawing. This technique involves shaping the raw material into a pipe form without any subsequent welding. As a result, seamless pipes exhibit a uniform structure without any seams.

Conversely, SS welded pipes are fabricated by welding a sheet along its longitudinal axis, forming it into a curved pipe shape. Some AISI 316 pipes undergo spiral welding to enhance their strength. The key distinction lies in the presence of seams, which can lead to variations in wall thickness for welded pipes, creating undulations. This variance in wall thickness, known as absolute roughness, is significantly less pronounced in seamless pipes. As a consequence, seamless pipes generally exhibit smoother internal surfaces compared to their welded counterparts.
