Purchasing Guide

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

  • For procurement requirements that require the use of flat welding flanges with diameters, it is recommended to prioritize checking key technical parameters such as nominal diameter and pressure rating to ensure compatibility with pipeline system design and avoid installation failure or sealing issues caused by specification deviations.
  • When using radial flat welding flanges in petrochemical or water supply systems, attention should be paid to the material's corrosion resistance requirements. For example, 304 stainless steel is suitable for general environments, while 316L is more suitable for high chloride ion working conditions.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. Such suppliers usually provide more stable batch delivery capabilities.
  • The pressure bearing performance of flat welded flanges with different thicknesses varies significantly. Before procurement, it is necessary to calculate the working pressure range of the system to avoid the risk of long-term deformation caused by the use of thin flanges.
