19、to the terms used in this specification.3.2 Definitions of Terms Specific to This Standard:3.2.1 moldedrefers to products preformed via a molding process to yield full-round cylindrical pipe insulation sections.3.2.2 precision v-grooverefers to products fabricated from machined board via a precision

20、 cutting process. Machinedsegments are adhered to a backing to form a full-round cylindrical pipe insulation section. Due to the precision of the process, theproduct has no gaps when installed.4. Classification4.1 Products covered by this specification are classified according to maximum use tempera

23、NOTE 1Warning: Grade B may not be suitable for applications requiring hot installation capability at the maximum temperature indicated. Productshaving a Grade B designation are designed to be used with a heat-up schedule. Failure to use a heat-up schedule with Grade B products may lead to anexotherm

24、ic reaction. This is dependent on thickness and temperature. Consult the manufacturer or manufacturers literature for special heat rateconsiderations.4.2 Binder decomposition at elevated temperature may be a limiting factor in certain applications. Consult the manufacturerregarding special heat rate

25、 considerations.5. Materials and Manufacturer5.1 Composition The mineral fiber insulation for pipes shall be manufactured from mineral substance such as rock, slag, orglass, processed from a molten state into fibrous form with binder. Asbestos shall not be used as an ingredient or component part.Som

26、e products may also contain adhesive.5.2 Jackets (Facings)The user of this specification has the option to specify that the insulation be jacketed.NOTE 2The user is advised that the maximum use temperature of factory-applied facings and adhesives may be lower than the maximum usetemperature of the i

27、nsulation. The specifier shall ensure that sufficient insulation thickness is installed so none of these accessory items (facings andadhesives) are exposed to temperatures above their maximum use temperature. The products covered by this standard are predominantly inorganic innature. Organic facings

28、, adhesives and binders are also used in the construction of these products. The resulting composite therefore could have increasedcombustibility.6. Physical Requirements6.1 The product shall conform to the following requirements in addition to those specified in Table 1.6.2 Hot Surface Performance:

29、6.2.1 The product shall not crack, warp, flame, or glow during hot surface exposure.

37、 NAVSEAA1.1 ScopeA1.1.1 In addition to the requirements of this standard, additional compression resiliency testing is required for Naval SeaSystem Command (NAVSEA) acceptance.A1.2 BackgroundA1.2.1 NAVSEA engineers, builds and supports Americas Fleet of ships and combat systems. This test is only re

38、quired ifNAVSEA acceptance is desired.A1.3 Test OverviewA1.3.1 Three 12-in. segments of half-round 3 by 2 in. (80 by 50 mm) thick mineral fiber pipe insulation are measured for initialthickness, then compressed 10 times to a maximum load of 200 lbs., then re-measured for thickness recovery after com

40、or supporting the 3-in. pipe,A1.4.6 A sample of 3-in. x 2-in. (80 mm by 50 mm) thick mineral fiber pipe insulation, andA1.4.7 A 12-in. (305 mm) saddle conforming to the outside diameter of the insulation.A1.5 Sample PreparationA1.5.1 Three 12-in. (305 mm) long, half-round segments of 332-in. (80 mm

41、by 50 mm) mineral fiber pipe insulation are cutfrom a full-round section.A1.6 Thickness DeterminationA1.6.1 A half-round 12-in. (305 mm) length of 3 3 2-in. (80 by 50 mm) pipe insulation is placed on a 3-in. (80 mm) NPS pipeand measured for thickness using the pin gauge and steel rule. The measureme

42、nts are in the center of the insulation length and 3-in.(75 mm) from each end. These values are recorded as the initial thickness. The measurement points are marked as there-measurement points after compression. See Fig. A1.1.A1.7 Compression SaddleA1.7.1 The sheet metal comprising the radius of the

43、 saddle shall be132 in. (13 gauge) (2 mm) or greater. See Fig. A1.2.A1.7.2 An alternative to metal is to use a half round of 8-in. nominal (280 mm) Schedule 80 PVC piping which has an averageinside diameter of 7.565 in. (192 mm).A1.7.3 The wooden portion shall be mechanically fastened to the radial

44、portion with wood screws.A1.8 Compression Resiliency TestA1.8.1 The half round insulation segment is placed in the half-round compression saddle designed to test pipe insulation (SeeFig. A1.3). The saddle may be placed on top of the half round segment, or the segment may rest in the saddle (upside d

45、own fromthe figures provided). If the saddle is placed on top, and is not fixed to the crosshead of the testing machine, then its mass shallbe taken into account as part of the pounds force applied to the half round section. If the saddle is on the bottom, then the 3 in.(80 mm) NPS pipe shall be fix

46、ed to the cross-head of the universal testing machine. Hence there would be no apparatus mass tobe accounted for.A1.8.2 Using the universal testing machine, the half-round section shall be loaded to a force of 200 lbs. (90 kg) and released.This is repeated a total of ten times. The test speed shall

47、be 0.5 in. (12 mm) per minute.A1.8.3 The compressed sample is re-measured for thickness after 15 min rest after the last compression and recorded. (See Fig.A1.1),A1.8.4 Three 12-in. (305 mm) long, half-sections shall be tested.A1.9 CalculationA1.9.1 The percent of thickness recovery after enduring t

48、en loading of a force equal to 200 lbs. per lineal foot (90 kg per 0.305m) is calculated as follows for the three tests:FIG. A1.1 Thickness DeterminationC547 126FIG.
