ASME Flat Welded flanges

Flat welded flange refers to a flange that is associated with a container or pipeline via ability of fillet weld. It is an arbitrary flange. During the design, in accordance to the integrity of the connection between the flange ring and the straight cylinder section, it is checked in accordance to the vital or free flange respectively. Flange rings are available with and barring neck. Compared with the butt welding flange with neck, the flat welding flange has a effortless structure and saves materials, alternatively the stiffness and tightness are now no longer as ideal as the butt welding flange with the neck. Flat welded flanges are extensively used in the connection of medium and low pressure vessels and pipelines.

Flat welded flanges are gorgeous for piping buildings with low pressure tiers and low stress fluctuations, vibrations and vibrations. The obtain of flat welding flange is that it is much less challenging to align when welding and assembling, and the cost is tremendously cheap, so it has been considerably used.

Product specs DN10-DN2000

Flat welding flanges are no longer allowed to be right now welded with tees, elbows and special pipe fittings, and straighten pipe sections are required.
