Installation Procedure

1. Ensure pipe ends are clean, free from debris, and properly chamfered for welding or fitting. 2. Use appropriate welding procedures (e.g., TIG welding with 316L filler material) or compatible fittings (e.g., socket-weld or threaded) as per design specifications. 3. Verify joint integrity through non-destructive testing (NDT) if required by the application's safety standards.

Common Mistakes & How to Avoid Them

❌ Mistake✅ Correct Approach
Using incompatible welding filler material that compromises corrosion resistance.Always use 316L or other recommended filler material for 316 stainless steel to maintain equivalent or superior corrosion properties.
Improperly cleaning pipe ends before joining, leading to weld defects or poor fitting connections.Thoroughly clean pipe ends with a degreaser and lint-free cloths to remove any oils, grease, or contaminants before welding or fitting.

Common Applications
