Purchasing Guide

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

  • For procurement requirements that require the use of large diameter flanges, it is recommended to prioritize checking key specification parameters such as flange outer diameter and bolt hole center distance to ensure compatibility with pipeline systems or equipment interfaces and avoid installation failure due to dimensional deviations.
  • In high-pressure scenarios such as petrochemicals or large-scale water conservancy projects, attention should be paid to the material pressure rating and sealing performance of large-diameter flanges. The selection of carbon steel or stainless steel materials should be based on the actual corrosion assessment of the medium.
  • 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 batch supply capabilities.
  • For the application of high-altitude structures such as wind turbine towers, it is recommended to require suppliers to provide fatigue strength test reports for large-diameter flanges during procurement, and confirm whether their long-term wind and vibration resistance performance meets industry standards.
