BISCO FLEXIBLE BOOTS S P - 505 1.0 PURPOSE
.To establish installation methods for BISCO Flexible Boot Penetration Seals where the criteria of pressure (Hydrostatic
/ Air), fire, radiation or any combination thereof exists.
2.0 SCOPE To provide the standard installation method for BISCO flexible boot seals capable of withstanding the design criteria.
3.0 GENERAL 3.1 Flexible boots designed to provide a specified criteria f's) may be installed directly to penetrants having a maximum o
s, operating temperature of 400 F.
3.2 Penetrants equipped with insdlation and requiring a flexible boot should be sealed for air infiltration through the insulation prior to boot installation.
3.3 Insulation seals on Stainless Steel piping shall be provided by a Biscoseal replacement ring or by Booting directly to the pipe.
3.4 Where a fire criteria \\is indicated, the flexible boot should be installed on the non-hazardous side of the barrier. In the event a potential fire hazard exists for both sides, or the hazard side cannot be determined, a flexible boot should be installed on both sides.
/
3.5 Fire configurations with stainless steel pipe penetrants must be sealed with Ceramic Fiber (Blanket Strips /
Bulk) which is certified for compliance with NRC Reg. Guide 1.36.
3.6 A flexible boot designed for use as a pressure seal (hydrostatic / air) should be installed on the negative side of the barrier for maximum resistance.

BzsCo FLEXIBLE Boots SP 505 Require'd boot clamps for the pipe and sleeve shall be 7.4 determined utilizing Boot Clamp Chart, FB-2, (attached).
7.4.1 Using Flexible Boot Worksheet Form FB-1, found in Production Procedure SP-504, determine the circum-farence of the pipe and sleeve to be clamped.
7.4.2 Find the corresponding closest circumference on Boot Clamp Chart FB-2, then determine required clamp part number in the far left column and the quantity in the top column. Where the pipe / sleeve circumferencc does not appear on Form FB-2, pick the next larger value on the chart.' In addition, whenever possible use the lessor multiple of clamps needed to band pipe / sleeve.

7.4.4 When attaching any series of clamps together, they should be threaded thru approximately one-half inch into the adioining clamp.
7.5 Apply 732 silicone sealant on both the pipe and sleeve for sealing surface (l" minimum width). Fold the boot ends over the sealant and position the clamp (s) on the boot fabric, and tighten.
