Now for all dimensions of double wall pipe
Due to popular demand, the AF Pipe flexible supports are now available in most common sizes for double wall pipe from 1/2″ to 12″ inner pipe. There are now three distinct product types available to accomodate all these sizes,
which vary in design and performance. The new datasheet for the AF Flex Support is found here
“Compact” type which is used to achieve the smallest possible outer pipe, for reductions in outer pipe cost and weight:
| Max inner pipe diameter | Min outer pipe diameter | ||
| NPS | DN | NPS | DN |
| 1” | 25 | 2 ½” | 65 |
| 1 ¼”, 1 ½” | 32, 40 | 3” | 80 |
| 2”, 2 ½” | 50, 65 | 4” | 100 |
| 3, 3 ½” | 80, 90 | 5” | 125 |
| 4, 4 ½” | 100, 115 | 6” | 150 |
“Standard” type which is used for larger annular space, and typically not as stiff as the compact type
| Max inner pipe diameter | Min outer pipe diameter | ||
| NPS | DN | NPS | DN |
| 1” | 25 | 3” | 80 |
| 1 ¼”, 1 ½” | 32, 40 | 4” | 100 |
| 2”, 2 ½” | 50, 65 | 5” | 125 |
| 3, 3 ½” | 80, 90 | 6” | 150 |
| 4, 4 ½” | 100, 115 | 8” | 200 |
| 5, 6” | 125, 150 | 10” | 250 |
“Centraliser” type, which is used for the larger dimenion pipes from 6″ inner pipe upwards, especially with heavy wet loads (liquids) where higher stiffness is required
| Max inner pipe diameter | Min outer pipe diameter | ||
| NPS | DN | NPS | DN |
| 6” | 150 | 8”/10” | 200/250 |
| 8” | 200 | 10”/12” | 250/300 |
| 10” | 250 | 12”/14” | 300/350 |
| 12” | 300 | 14”/16” | 350/400 |
