Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of insulated joints, it is recommended to prioritize checking key technical parameters such as voltage level, diameter size, and corrosion resistance to ensure compatibility with existing pipeline systems.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers have richer application cases in the fields of oil and gas transportation or chemical engineering.
  • Insulated joints play a crucial role in cathodic protection systems for long-distance pipelines, and products with corresponding protection levels should be selected based on differences in buried or overhead environments during procurement.
  • If it involves supporting high-voltage power facilities, it is recommended to conduct a comprehensive evaluation based on leakage current indicators and insulation resistance parameters, while paying attention to the actual project experience of suppliers in the energy industry.
