The standard sanitary internal surface finish in the food, dairy and beverage markets is 32Ra. This has been determined by the 3A (the organization that sens standards for the dairy industry) to be the minimal standard for piping. The pharmaceutical industry uses a broader range of surface finishes as determined by the end user. Most biopharmaceutical company specifications now adhere to the ASME BPE standards. The ASME BPE categorizes 7 different surface finishes, 4 for mechanically polished fittings/tubing and 3 for mechanically polished plus electropolished.
