Purchasing Guide

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

  • For procurement requirements that require the use of large-diameter flange plates, it is recommended to prioritize checking key technical parameters such as nominal diameter and pressure rating to ensure compatibility with pipeline system design standards. For example, in the chemical or energy fields, DN500 or higher specifications are often required.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. These suppliers usually have more stable supply capabilities in large-scale infrastructure projects.
  • In high-pressure scenarios such as long-distance pipelines or sewage treatment, attention should be paid to the corrosion resistance of flange materials. 316L stainless steel or alloy materials are more suitable for high salt or acidic medium environments.
  • There are significant differences in the requirements for the sealing surface form in different application scenarios. For example, RF flanges are suitable for conventional working conditions, while RTJ flanges are more suitable for high-temperature and high-pressure oil and gas transportation needs.
