Purchasing Guide

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

  • For procurement requirements that require the use of flanges, it is recommended to prioritize checking key technical parameters such as pressure rating and diameter size to ensure compatibility with pipeline system design standards and avoid installation failure due to specification errors.
  • In high-pressure scenarios in the chemical or energy industries, it is recommended to choose forged steel flanges to ensure pressure performance, while cast iron flanges with better cost can be considered for water supply and drainage systems, which need to be comprehensively evaluated based on the characteristics of the medium and working conditions.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, suppliers who have long-term stable supply of flanges in the petrochemical field usually have more reliable industry verification records.
  • When purchasing flanges, attention should be paid to whether the supplier provides complete material reports and testing data. Carbon steel flanges should be clearly marked with ASTM A105 and other standards, while stainless steel flanges should be labeled with specific material codes such as 316L or 304 to meet anti-corrosion requirements.
