POC/R.DEMPSEY/CIV/SEA 05M3/LOC: WASHINGTON DC/TEL:COM 202-781-3660 /TEL:DSN 326-3660// RMKS/

1. THE PURPOSE OF THIS ADVISORY MESSAGE IS TO APPROVE K-FLEX ECO INSULATION FOR USE ON HOT PIPING UP TO 300 DEGREES F ON SURFACE SHIPS. K-FLEX ECO MAY BE USED AS AN ALTERNATIVE TO MIL-I-22344 LOW TEMPERATURE FIBERGLASS, MIL-I-2781 CALCIUM SILICATE AND DOD-I-24688 POLYIMIDE PIPE INSULATION FOR USE ON HOT PIPING UP TO 300 DEGREES F. K-FLEX ECO MEETS ALL OF THE REQUIREMENTS OF REF A, WHICH INCLUDE A K-FACTOR OF 0.30 MAX AT 75 DEGREES F AND COMPRESSION RESISTANCE AT 25 PERCENT DEFLECTION OF 2 TO 6 LB/SQ IN. THE KEY PHYSICAL PROPERTIES EVALUATED ON THE K-FLEX ECO FOR HOT PIPE APPLICATIONS ARE THERMAL CONDUCTIVITY, COMPRESSION RESISTANCE AND SURFACE TEMPERATURE OF THE INSULATION.

2. A 16-MONTH SHIP TEST WAS PERFORMED ON USS RUSHMORE (LSD 47) WHERE K-FLEX ECO WAS INSTALLED ON 15 AND 50 POUND STEAM LINES WITH MAXIMUM TEMPERATURES APPROXIMATING NEAR 300 DEGREES F. AFTER PAGE 08 RULSSEA0357 UNCLAS 16-MONTHS SHIPBOARD EXPOSURE, LABORATORY THERMAL CONDUCTIVITY AND COMPRESSION TESTS WERE PERFORMED ON THE K-FLEX ECO. THERE WAS MINIMAL CHANGE IN THERMAL CONDUCTIVITY BETWEEN THE ORIGINAL AND THE 16-MONTH SAMPLE. THE K-FLEX ECO CONTINUED TO MEET THE COMPRESSION RESISTANCE REQUIREMENT OF REF A AFTER 16 MONTHS EXPOSURE. THE SURFACE TEMPERATURE OF THE K-FLEX ECO WAS MEASURED ON THE 50 POUND STEAM LINE DURING THE SHIPBOARD INSPECTION. THE SURFACE TEMPERATURE OF THE INSULATION WAS 86 DEGREES F - WELL BELOW THE 125 DEGREES F MAXIMUM SURFACE TEMPERATURE SPECIFIED IN REF B. THIS WAS 7 DEGREES F COOLER THAN ADJACENT MIL-I-22344 FIBERGLASS INSULATION ON THE SAME 50 POUND STEAM LINE. THIS IS CONFIRMATION THAT THE K-FLEX ECO PERFORMS THERMALLY ON HOT PIPING. THE FINAL EVALUATION CONCLUDES THAT K-FLEX ECO PERFORMS AS A THERMAL INSULATION ON HOT PIPING WITH DESIGN TEMPERATURES UP TO 300 DEGREES F.

3. K-FLEX ECO OFFERS APPROXIMATELY A 70 PERCENT WEIGHT REDUCTION AS

AN ALTERNATIVE TO CALCIUM SILICATE FOR LOW TEMPERATURE STEAM APPLICATIONS. IT PROVIDES LABOR SAVINGS IN THAT THE INSULATION IS USER FRIENDLY DURING INSTALLATION AND REMOVAL. THE MATERIAL IS CUT EASILY WITH NO DUSTING. NO FACEMASKS ARE REQUIRED TO INSTALL K-FLEX ECO. WHEN IT IS REMOVED FROM THE PIPE, THERE IS NO DUST OR CEMENT PAGE 09 RULSSEA0357 UNCLAS ADHERED TO THE PIPE. THE PIPE CAN EASILY BE RE-INSULATED WITH NO SCRAPING OR INTENSIVE CLEANING REQUIRED.

4. REF C STILL APPLIES REGARDING THE SOURCES FROM WHICH K-FLEX ECO

INSULATION CAN BE OBTAINED, INCLUDING THE FOLLOWING ADDITIONAL SUPPLIERS:

5. REF D CLARIFIES THAT MATERIALS CONFORMING TO REF A ARE APPROVED

FOR USE ON PIPING SYSTEMS ONLY.

6. THE APPROVED LAGGING MATERIALS AND ADHESIVES TO BE USED WITH

K-FLEX ECO ARE PROVIDED IN REF E.

7. REQUEST WIDEST DISSEMINATION AND RE-ADDRESSAL TO SUBORDINATE

COMMANDS.
