Notes: 1) Pressure ratings based on ASTM A312 Type 304 stainless steel pipe or equivalent.
2) Failure to use Rollers specifcally designed for Stainless Steel Pipe may signifcantly reduce pressure retention capabilities.
3) Pressure ratings on cut grooved pipe meet or exceed the schedule 40 pressure ratings listed above. For information regarding higher ratings contact Anvil.
4) * For pressure ratings on Figure 7010 Reducing Couplings use larger pipe size.
5) For pressure ratings for the reducing tees, concentric reducers and eccentric reducers, use the rating of the weakest end.
6) Pressure ratings on schedule 10 stainless steel pipe may be increased by using Anvil's 1007/3007 roll groovers with the schedule 10 roller set. Contact Anvil for details.
The following are pressure ratings for Gruvlok Stainless Steel
Piping Systems. The ratings for Schedule 10S pipe are based
upon the use of roll-groover roll sets that have been specifcally
designed for use on Schedule 10 Stainless Steel pipe. Using roll
sets that were designed for roll grooving standard wall pipe may
signifcantly reduce the pressure ratings that can be obtained.
The Model 1007/3007 roll groovers require the use of the
optional Schedule 10 roll set to groove Schedule 5S and 10S. For
grooving Schedule 40S on the Model 1007/3007 roll groovers,
the standard steel roll grooving set should be used.
