Hastelloy C-276 welded pipe
Hastelloy C-276 Features of welded pipe
Corrosion resistance: Hastelloy C-276 welded pipes exhibit excellent corrosion resistance in a variety of corrosive media, including both oxidation and reducing environments.
Welding performance: Hastelloy C-276 welded pipe is easy to weld, and it can still maintain good corrosion resistance after welding.
High temperature performance: At high temperature, Hastelloy C-276 welded pipe can still maintain good mechanical properties and corrosion resistance.
Production Engineering:
Raw material preparation
Use Hastelloy C-276 or S32760 sheet or strip conforming to ASTM A249 or ASTM A312 standards as raw material.
Shear and edge preparation
Sile plates or strips to appropriate sizes and process edges to ensure accurate docking during welding.
Roll
the cut plate or strip roll into a tube.
Welding
Weld the edges of the pipe using welding techniques such as TIG (tungsten pole argon arc welding) or MIG (metal inert gas protection welding).
Heat treatment
After the welding is completed, the welded pipe is fixed by heat treatment to restore the corrosion resistance and mechanical properties of the material.
Straighten and cut
Straighten and cut the welded pipe to achieve the desired size and shape.
NDT
Conduct nondestructive testing such as ultrasonic testing or radiographic testing to ensure that the welded pipe is free of defects.
Surface treatment
Surface-treat the welded pipes, such as pickling, passivation or polishing, to improve their corrosion resistance and aesthetics.
Inspection and testing
Final inspection and testing of welded pipes, including dimensional inspection, pressure test and chemical composition analysis.
Packaging and transportation
Qualified welded pipes are properly packed and ready for shipment.
