Purchasing Guide

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

  • For procurement requirements that require the use of stainless steel flange connections, it is recommended to prioritize confirming the standard specifications (such as DN/PN values) and material grades (such as 304 or 316L) of the flange connections to ensure compatibility with the pipeline system.
  • In corrosive environments such as chemical or food processing, the sealing performance and acid and alkali resistance of stainless steel flange connections are key parameters, and corresponding surface treatment processes need to be selected based on the characteristics 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 to avoid project progress being affected by unstable supply.
  • For high-pressure pipeline applications, it is recommended to verify the pressure temperature rating of stainless steel flange connections and ensure that the third-party testing report provided by the supplier covers the relevant operating conditions requirements.

Knowledge Base

Q

This article provides a detailed answer to the issue of bolt selection for stainless steel flanges, covering key factors such as material matching, strength grade, and anti-corrosion treatment. We recommend using A2/A4 stainless steel bolts or galvanized carbon steel bolts, and emphasize the adaptation schemes under different working conditions. At the same time, we provide installation torque reference values and anti loosening measures to ensure the reliability and durability of flange connections.
