HomeMy WebLinkAbout330.5Where shown on the plans or in the specifications or required by
the Engineer, joint restraint system (shackle rods) shall be used.
All joints restraint materials used shall be those manufactured by
Star National Products, 1323 Holly Avenue, PO Box 258,
Columbus,. Ohio 43216 unless an equal alternate is approved in
writing by the Engineer.
Materials
Steel Types:
High strength low—alloy steel (cor—ten),
ASTM A588 heat—treated.
1. Tebolt:
ASTM A588, Grade B, Cor—Ten, equal to SuperStar Tielbolt
SST 7 5/8" for 2" and 3" mechanical joints (M.J.) with eye for 5/8" rod
SST 7 3/4" for 4" to 12" M.J. with eye for 3/4" rod
SST 756: 3/4" for 14" to 24" M.J. with eye for 3/4" rod
SST 747: 3/4" for 4" to 12" M.J. with eye for 7/8" and 1" rod
SST 757: 3/4" for 14" to 24" M.J. with eye for 7/8" and 1" rod
SST 778: 1" for 30" to 36" M.J. with eye for 1" rod
2.Tienut: Hex Nut
ASTM A588, Grade B, Cor—Ten, equal to SuperStar Tienut
SS8 for 5/8", 3/4", 7/8", 1" Tiebolt and Tierod
3.Tiecoupling with Tiestop Pin
ASTM A588, Grade B, Cor—Ten, equal to SuperStar Tiecoupling
SS10 for 5/8", 3/4", 7/8", 1" Tierod
4. Tierod:
Continuous threaded rod for cutting to desired lengths
ASTM A588, Grade B, Cor—Ten, equal to SuperStar Tierod
SS12 for 5/8", 3/4", 7/8", 1"
5. Tiewasher
ASTM A588, Grade B, Cor—Ten, equal to SuperStar Tiewasher
SS17 for 5/8", 3/4", 7/8", 1" round flat washer
Installation:
Install the joint restraint system in accordance with the Manufacturer's
instructions so all joints are mechanically locked together to prevent joint
separation.
Tiebolts shall be installed to pull against the mechanical joint body and
not the M.J. follower. Torque nuts at 75-90 foot pounds for 3/4" nuts.
Install tiecouplings with both rods threaded equal distance into
tiecouplings. Arrange tierods symmetrically around the pipe.
Where a Manufacturer's mechanical joint valve or fitting is supplied with
slots for "T" bolts instead of holes, a flanged valve with a flange by
mechanical joint adaptor shall be used instead, so as to provide adequate
space for locating tiebolt.
Where a continuous run of pipe is required to be restrained, no run of
restrained pipe shall be greater than 60 feet in length betwee fittings.
Insert long body solid sleeves as required on longer runs to keep tierod
lengths to the 60 foot maximum.
Pipe used in continuously restrained runs shall be mechanical joint pipe
and tiebolts shall be installed as rod guides at each joint.
