Ribs should NEVER be substituted for Spines. Ribs & Spines from
different duty ratings should not be mixed.
NOTE: SPM's Medium Duty FSR System is rated for use on 4"
treating iron up to 10,000 psi. In instances where the product
is required for 4" 1502 lines, a double wrapping technique may
be used that will provide acceptable load rating for the flow line.
Please contact Weir Oil & Gas Engineering at 1-800-342-7458 for
more details regarding the double wrap procedure or if you have
further questions.
