ОглавлениеThe process designer must also consider the corrosive nature of the fluids involved when selecting construction of materials for the various process and utility service lines. Some designers attach these materials designations to the line designation on the flowsheets, while others identify them on the Line Summary Table (Figure 14.20d). Some typical pipe materials designations are:
| CS40 | - Carbon steel, Sch. 40 |
| CS80 | - Carbon steel, Sch. 80 |
| SS316/10 | - Stainless steel 316m Sch. 10 |
| GL/BE | - Glass bevel ends |
| N40 | - Nickel, Sch. 40 |
| TL/CS | - Teflon-lined carbon steel |
| PVC/CS Polyvinyl chloride | - lined CS |
