Frequently asked questions
When should I use weld fittings instead of compression or flare fittings?
Weld fittings are preferred when disassembly is not needed and maximum vibration resistance is required — for example, on heavy mobile equipment, mining machinery, or offshore hydraulic systems. They eliminate the thread loosening and cutting ring fatigue that can occur with repeated assembly cycles.
What welding process is suitable for your stainless steel weld fittings?
TIG (GTAW) welding is recommended for SS316L fittings to avoid heat tint and maintain corrosion resistance. For carbon steel, MIG (GMAW) or TIG is acceptable. We can supply material test certificates and weld procedure recommendations on request.
