Purchasing Guide

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

  • For procurement requirements that require the use of reducers, it is recommended to prioritize confirming the nominal diameter and pressure rating of the connecting pipes at both ends to ensure product specifications are compatible with the piping system.
  • In corrosive media scenarios such as chemical or water treatment, attention should be paid to the material selection of reducers, such as stainless steel or plastic lining materials, which can improve corrosion resistance.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to ensure supply stability.
  • Reducing pipes are commonly used in HVAC systems for branch pipe diameter changes. When purchasing, it is necessary to consider the technical requirements of fluid characteristics on wall thickness and connection methods.

Knowledge Base

Q

This article analyzes how to choose reducer joints reasonably from three dimensions: material compatibility, size matching, and installation precautions, to help industrial users solve practical problems in pipeline variable diameter connections.

Q

The roundness of the reducer should not exceed 1% of the corresponding end outer diameter, and the allowable deviation is ± 3mm. The material of the reducer should comply with SY/T5037, GB/T9711, GB/T8163, American standard ASTM A106/A53 GRB, API 5L, APT5CT, ASTM A105, ASTM A234
