There are wide stainless tubing dimensions to choose from, large diameter, heavy wall, or small diameter is available, the schedule number refers to the wall thickness of the stainless steel pipe, there are several Schedule numbers to meet different requirements, including SCH.5S, SCH.10, SCH.10S, SCH.20, SCH.30, SCH.40, SCH40S, SCH.80, SCH80S and larger Schedule No., when the number increases, the thicker the wall thickness with the same NPS dimensions, also the wall thickness changes based on the nominal pipe size (NPS).
