ASTM C547 Stone Wool Pipe

Insulation Stone wool pipe is a product specially designed for pipe insulation needs. It creates a good insulation environment for pipes and reduces energy consumption, can be applied to pipeline engineering. The basalt fiber inside can reduce heat loss and stabilize the temperature inside the pipeline.

How to judge the quality of a good insulation Stone wool pipe from its appearance?

1. The surface of a good Stone wool pipe is relatively flat, without obvious bumps, wrinkles or deformations. When installing a pipeline insulation project, a relatively flat Stone wool pipe can be more evenly wrapped around the pipe, reducing air gaps and improving the insulation effect. The flatness deviation should generally not exceed ±2m.
2. 
3. 2. The color of a good insulation Stone wool pipe should be uniform, without obvious color differences or color spots. If the color is different in depth, it may mean that there is a problem with the product quality.

3. A good insulation Stone wool pipe should have strict dimensional control, and the deviation of its inner diameter, outer diameter, and length should be within a very small range. For common Stone wool pipes for pipeline insulation, the inner diameter deviation should generally not exceed ±2mm, the outer diameter deviation should not exceed ±2mm, and the length deviation should not exceed ±5mm.
