We offer Schedule 40/40S wall thickness stainless steel pipe to meet various applications, the commonly used grades have 304/304L 316/316L stainless steel, these grades possess excellent corrosion resistance suited to many industries, such as oil & gas, petrochemical engineering & chemical industry.
There are wide stainless steel pipe dimensions to choose from, large diameter, heavy wall, or small diameter is available, the schedule number refers to the wall thickness of the 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).
The relationship between pipe size, schedules and wall thicknesses is simply to refer to a conversion chart, Pipe Schedule based on ASME B36.19 & ASME B36.10, for Carbon Steel and Wrought iron Pipe as per ASME B36.10, for Stainless Steel Pipe as per ASME B36.19, the Schedule NO. with letter “S”, which means for stainless steel pipe.
