Rapid Stock Turnaround
Large stock of 1/2" to 3" blanks (3000#/6000#) allows for 1-week delivery on most custom orders.
FAQ
Q1. How is the sealing of SW?
Far superior to threaded joints; ideal for hazardous or high-pressure systems.
Q2. Is a welding gap necessary?
Yes, a 1.5mm gap is required to buffer thermal expansion during welding.
Q3. Is it corrosion resistant?
Yes. Solution annealing restores the micro-structure for excellent corrosion resistance.
Q4. How to verify quality?
Dye Penetrant Testing (PT) on the finished weld is recommended to detect surface cracks.
