Purchasing Guide

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

  • For procurement requirements that require the use of explosion-proof junction boxes, it is recommended to prioritize confirming key technical parameters such as protection level, material corrosion resistance, and applicable gas groups to ensure compatibility with the hazardous environment on site.
  • In explosive scenarios such as chemical or mining, explosion-proof junction boxes with high shell strength and stable sealing performance should be selected, while paying attention to the differences in structural requirements for different installation methods (such as wall mounted or pipeline).
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support or platform statistical information. Such suppliers can usually provide more stable product supply.
  • For high salt spray environments such as offshore platforms, it is recommended to use explosion-proof junction boxes made of 316 stainless steel and verify whether the supplier has practical application cases of similar projects.
