Purchasing Guide

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

  • For procurement requirements that require the use of size heads, it is recommended to prioritize confirming the nominal diameter and wall thickness parameters of the connecting pipes at both ends to ensure compatibility with the existing pipeline system.
  • In high-pressure scenarios such as chemical engineering or water supply and drainage, the selection of materials for the size of the head should take into account both corrosion resistance and pressure bearing capacity. 304 stainless steel or galvanized carbon steel is a common option.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support to reduce procurement risks.
  • By adjusting the structural form of the large and small heads according to the characteristics of the conveying medium (such as high temperature and particle content), eccentric design can avoid the problem of liquid accumulation under gas-liquid mixing conditions.

Knowledge Base

Q

Choosing the appropriate size for the water supply and drainage system requires comprehensive consideration of multiple factors. Firstly, it is necessary to clarify the diameter of the connecting pipeline. The diameter of the pipes at both ends of the large and small ends should be accurately matched with the diameter of the connected pipeline. For example, if one end is connected to a pipeline with a nominal diameter of 50mm and the other end is connected to a pipeline with a nominal diameter of 100mm, then it is necessary to choose the pipe diameters for both ends

Q

This article introduces the names and uses of large and small heads with flanges, and explains their common application scenarios.
