Yanghong will tell you how stainless steel spheres achieve the effect of preventing steel from rusting.

The core reason why stainless steel spheres prevent steel from rusting lies in their unique alloy composition and surface treatment process. By forming a dense oxide film, reducing the contact with corrosive media, and optimizing the surface condition, they achieve long-term anti-corrosion effects. Here is the specific principle and implementation method:

The advantages and maintenance guidelines of the three-way ball valve

I. Core Advantages 1. Flexible switching through multiple channels L-shaped flow channel: Achieves two inputs and one output (such as A→B or A→C), suitable for medium distribution or switching scenarios, such as raw material switching in chemical pipelines. T-shaped flow channel: Supports three-way flow, capable of achieving medium mixing (such as A+B→C), diversion or full on/off. Commonly used in systems requiring dynamic adjustment, such as the mixing of cold and hot water in HVAC systems.

The hardening methods of the ball body and valve seat of the metal hard-sealed ball valve

The hardening methods for the ball body and valve seat of metal hard-sealed ball valves are diverse. Here are some of the main hardening methods and their characteristics: 1. Hard alloy overlay welding: Features: The hardness can reach above 40HRC, and it has excellent wear resistance. Disadvantages: The process is complex, the production efficiency is low, and large-scale welding can easily cause deformation of the parts. Application: Currently, the process for harden
