When sampling bulk material, a pipeline can be used for a variety of reasons, depending on what the bulk material is and the sampling techniques used. Here are some typical use cases:

  1. Transportation of material: In many cases, the bulk material is transported from one place to another through a pipeline, such as from a silo to a processing area. The pipeline can then be used as a convenient point for sampling, as the material is already in motion.
  2. Continuous sampling: In some industries, such as food or chemical production, continuous sampling may be required to monitor the consistent quality of the product. Pipelines enable such continuous sampling by allowing samples to be taken directly from the flow of the material.
  3. Reduction of contamination: Pipelines can be closed and controlled, which can minimize contamination of the sample by environmental influences. This is especially important in industries where purity and quality are critical.
  4. Incorporation of sampling equipment: Specialized sampling equipment, such as automatic collectors, can be integrated directly into a pipeline to provide efficient and accurate sampling.
  5. Health and safety: In some cases, the bulk material may be dangerous or harmful to health, and a pipeline allows sampling without direct contact with the material.
  6. Temperature control: When the bulk material needs to be kept at a certain temperature, an insulated pipeline allows sampling without temperature fluctuations.
  7. Sampling of gases and liquids: In some cases, the bulk material may contain gases or liquids that must be detected during sampling. Pipelines may be designed to enclose these components and allow for representative sampling.

So, the use of a pipeline in bulk material sampling is in many cases a practical and efficient method that can improve both the accuracy of sampling and the safety and efficiency of the overall process.
