However, many pipes are buried or hidden underground and therefore invisible, which makes maintenance more difficult. In the past, a small pipe leak might have made a mess of the ground, but now

  • Share what to look for in geothermal drilling

      When geothermal wells are drilled, thermal response experiments are usually conducted through test wells, and then more accurate data are obtained through special software calculations before drilling.  1、According to the hydrogeological investigation report and water resources demonstration repor

  • What kind of research should be done before drilling a well in a spa?

    One of the most important aspects of spa project development is spa drilling, so in the early stages of spa construction it is necessary to find a spa drilling company with good quality, good service and good after-sales service to drill the well.
