    Proper installation is key to ensuring the longevity and integrity of your piping system. Incorrect welding can compromise the corrosion resistance of stainless steel. Follow these best practices for a successful installation.
    ​Critical Steps for a Quality Weld:​
    1. ​Preparation:​​ Bevel pipe ends to the correct angle (37.5°). Meticulously clean all surfaces with a dedicated stainless steel brush and solvent.
    2. ​Alignment & Tack Welding:​​ Ensure perfect alignment and use tack welds to secure the fitting.
    3. ​Welding Process (TIG Recommended):​​ Use the correct filler metal (ER308 for 304, ER316 for 316).
    4. ​Gas Purging (Essential):​​ Use argon backing gas on the inside of the weld joint to prevent "sugaring" (oxidation), which destroys corrosion resistance.
    5. ​Heat Control:​​ Use low heat input to minimize the heat-affected zone and prevent distortion.
    6. ​Post-Weld Treatment:​​ Remove heat tint by pickling and passivation to restore the protective oxide layer.
