Title Steel Pipe Dimensions & Sizes Chart (Schedule 40, 80 Pipe) Means
Description Steel Pipe Dimensions & Sizes Chart (Schedule 40, 80 Pipe) Means People always confused about how to describe steel pipe dimensions (sizes) in correct ways,Prefab Villas Supplier or how to clarify to seller what exactly pipe size we are going to purchase. In case any misunderstandings or a different size we purchased, that will be a big trouble.The standard covers the standardization of steel pipe dimensions and sizes. These pipes includes seamless or welded types, and applied in high or low temperature and pressures. The pipe distinguished from tube (Pipe vs Tube), here the pipe is specially for pipeline systems, fluids transmissions. Use the standard of ASME B 36.10M.In this standard, the pipe Outer Diameter smaller than 12.75 in, pipe actual diameters is larger than NPS (Nominal Pipe Size)or DN (Nominal Diameter).Second, for NPS 1/8 (DN 6) to NPS 12 (DN 300), these are based on a standard outside diameter (O.D.) This O.D. was originally selected to specify pipe dimension, but as the pipe always have an wall thickness and internal diameter (ID). For small pipe, there is a different size between OD and ID (Wall thickness), but as the pipe dimensions became larger, the OD and ID approximately to become equal. As there is no such relation between the old standard thickness (O.D.) and Nominal Size, so both of them accepted by standard ASME B 36.10 M.Steel pipe schedule is a indicating method represented by ASME B 36.10, and also used in many other standards, marked with Sch. Sch is the abbreviation of schedule, generally appearing in the American steel pipe standard, which is a prefix of a series number. For example, Sch 80, 80 is a pipe number from chart/table ASME B 36.10. Since the steel pipe main application is to transport the fluids under pressure, so their internal diameter is their critical size. This critical size is taken as nominal bore (NB). Therefore, if steel pipe carry the fluids with pressure, it is very important that pipe shall have enough strength and enough wall thickness. So wall thickness is specified in Schedules, which means the pipe schedule, abbreviated as SCH. Here ASME is the given standard and definition for the pipe schedule.As describing the steel pipe parameter, we usually use the pipe schedule, It is a method that represent pipe wall thickness with number. Pipe schedule ( sch. ) is not a wall thickness, but a wall thickness series. Different pipe schedule means different wall thickness for the steel pipe in the same diameter.
