Product Introduction
Welded titanium pipe can be a good choice for handling sodium hypochlorite because titanium is highly resistant to corrosion, including the corrosive effects of sodium hypochlorite. Sodium hypochlorite is a strong oxidizing agent and can cause corrosion in many materials. However, grade 2 titanium pipe has excellent corrosion resistance due to its ability to form a thin, protective oxide layer on its surface, which prevents further oxidation and corrosion. These systems are carefully designed expansion joints.

Gr2 Titanium Welding
The gr2 titanium welding process has a huge impact on the quality of welded titanium pipes. The challenge is oxygen embrittlement. When the heated during the welding process, oxygen - like oxygen in ambient air - penetrates and destroys the weld. This makes the metal brittle in use and prone to cracking or breaking prematurely. Gr2 titanium welding requires the use of an inert gas, usually argon. Therefore, it is necessary to strictly control the quality of argon. Properly it will appear bright, shiny, and silver once finished. Any discoloration could indicate a problem. Certain colors - such as blue, purple, and brown - are clear signs of serious problems and poor-quality welds, which can lead to embrittlement and product failure. This creates a risk of leakage of sodium hypochlorite during storage and delivery. The above photo of Gr2 titanium welded pipe can show the best welding process.
Sodium hypochlorite
It is a good choice for handling sodium hypochlorite due to its excellent corrosion resistance. Grade 2 titanium pipe is often used for handling sodium hypochlorite because it has good corrosion resistance and is relatively affordable. The titanium welding process is very important for it.
