FAQS
1. What is a Stainless Steel Flat Weld Flange?
A Stainless Steel Flat Weld Flange is a pipe flange connected by flat welding, commonly used for joining pipes, valves, pumps, and equipment in industrial piping systems.
2. What are the advantages of a flat weld flange?
Its advantages include simple installation, reliable connection, easy maintenance, cost efficiency, and good corrosion resistance when manufactured with suitable stainless steel grades.
3. What stainless steel grades are available?
Common grades include 304, 304L, 316, and 316L stainless steel. Other grades can be supplied according to application requirements.
4. What is the difference between Flat Weld Flange and Weld Neck Flange?
A Flat Weld Flange uses a simpler welding connection method, while a Weld Neck Flange uses a tapered hub and butt-weld connection, making it more suitable for higher pressure and demanding applications.
5. Can the flange be customized?
Yes. Queen Metal provides customized flat weld flange solutions based on required grade, size, thickness, pressure rating, facing type, bolt-hole pattern, standard, and application.
