Purchasing Guide

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

  • For procurement requirements that require the use of plugs, it is recommended to prioritize confirming key technical parameters such as thread specifications, material pressure resistance levels, etc., to ensure compatibility with pipeline or equipment interfaces.
  • 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 have more stable supply capabilities in industrial fluid systems and other scenarios.
  • Different application scenarios, such as chemical pipeline sealing or hydraulic equipment protection, have varying requirements for the corrosion resistance and pressure performance of plugs. Therefore, specific usage environments need to be clearly defined when purchasing.
  • Special attention should be paid to the material strength and sealing performance of plugs used in high-pressure environments such as oil and natural gas. It is recommended to choose suppliers with stable industry performance to reduce the risk of leakage.
