| ASBESTOS-CEMENT (A-C) PIPE | ||||||||||
| Only one pressure loss table is ordinarily provided for | ||||||||||
| all classes of A-C pipe although, theoretically, some | ||||||||||
| different classes have different inside diameters. However, | ||||||||||
| because of the wide latitude for dimensions allowed | ||||||||||
| by current standards, diameters of different classes overlap | ||||||||||
| to a considerable extent. Therefore, a single safe average | ||||||||||
| diameter for each size pipe is used in construction of | ||||||||||
| pressure loss tables. This diameter is consistent with | ||||||||||
| asbestos-cement pipe industry usage. The value of "C" | ||||||||||
| recommended by manufacturers of A-C pipe is "140." | ||||||||||
| And, this value was used in construction of the pressure | ||||||||||
| loss table for A-C pipe. | ||||||||||
