Different colors of raw material strips mainly have differences in purpose identification and visual distinction, and usually do not have essential differences in material and basic performance. The following will introduce them from the aspects of purpose, visual, and performance: Usage identification In some industry applications, different colored raw material tapes can be used to distinguish different types of pipeline systems or media. For example: Blue raw material tape May be used for waterway pipelines, indicating that the pipeline is transporting water related media. Yellow raw material tape Commonly used in natural gas pipelines and other gas systems, it serves as a warning to remind users that the pipeline contains flammable gas and requires careful operation. Visual differentiation In complex installation environments or multiple pipeline systems coexisting, different colored raw material tapes facilitate quick identification and differentiation of different pipelines by installation and maintenance personnel, making construction and maintenance easier. Multi pipeline parallel In industrial pipeline installation, when multiple pipelines such as water, gas, and oil are laid side by side, different colored raw material tapes are wrapped around the pipeline interfaces to allow people to distinguish the purpose of each pipeline at a glance. Material and Performance Although the colors are different, as long as it is a qualified raw material strip product, its main material is generally polytetrafluoroethylene, and there is usually no significant difference in basic sealing, chemical corrosion resistance, high temperature resistance, low temperature resistance and other properties due to color. sealing performance Regardless of the color, the raw material tape has good self sealing properties, filling gaps in threaded connections to prevent medium leakage. Temperature resistance Can maintain stable performance within a certain temperature range and adapt to common working temperature environments.
