GENERAL

1.1

This standard sets forth specifications and acceptable products for preformed pipe insulation of 0.5" to 24" inner diameters. (For inner diameters greater than 24" see Equipment Insulation)

1.2

This standard covers above and below grade applications for piping systems operating at temperatures ranging from ambient to 1200 ºF (649 ºC).

1.3

This standard will address wall thickness and multiple layer recommendations.

2.

APPLICATIONS

2.1

HIGH TEMPERATURE PIPING 600 ºF(316 ºC) to 1200 ºF(649 ºC)

The pipe insulation shall be premolded and core formed.

A thermal calculation should be performed to determine the proper insulation thickness to ensure either personnel protection or process control. Where the insulation thickness exceeds 3", a multiple layer system is recommended.

2.1.1

COMPOSITION:

Basalt wool and organic binder which is non-combustible and asbestos free.

2.1.2

DENSITY:

The density to be between 6.8 and 8.6 pcf.

2.1.3

MAXIMUM THERMAL CONDUCTIVITY:

The thermal conductivity shall not exceed the following as per ASTM C547

2.1.4

MAXIMUM NON-FIBROUS (SHOT) CONTENT:

The percentage content of non-fibrous material (shot) shall not exceed 20% by weight.

2.1.5

LINEAR SHRINKAGE:

The linear shrinkage, when tested at 1200°F (649°C), shall be less than 1%.

2.1.6

STRESS CORROSION:

The material must not promote or contribute to the corrosion of austenitic stainless steel.

2.1.7

SURFACE BURNING CHARACTERISTICS:
as per CAN/ULC S102 AND UL E84

Shall not exceed
