Questions & Answers
What is a fabricated welded reducer?
A welded reducer is a size change fabricated from rolled and welded plate or pipe, in concentric or eccentric form, for large diameters outside the standard wrought fitting range. It is designed to ASME B31.3 or AWWA C208 and coated to the project specification.
What size range do you supply for welded reducers?
20″–100″ large bore. Other sizes can usually be supplied on request — send your requirement for confirmation.
Which standards and grades are available?
Plate — EN 10025: S235JR · S275 · S355 · ASTM A234: WPB (carbon) · ASTM A403: WP304 · WP316 (stainless). See the datasheet for the complete list.
