Flat welded flange refers to a flange that is associated with a container or pipeline with the resource of way of workable 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 quintessential or free flange respectively. Flange rings are on hand with and barring neck. Compared with the butt welding flange with neck, the flat welding flange has a integral form and saves materials, then as quickly as higher the stiffness and tightness are now no longer as best as the butt welding flange with the neck. Flat welded flanges are significantly used in the connection of medium and low stress vessels and pipelines.

Plate flat welded metal pipe flange, flat welded metal pipe flange with neck

Flat welded flanges are magnificent for piping constructions with low pressure tiers and low stress fluctuations, vibrations and vibrations. The achieve of flat welding flange is that it is lots a lot much less challenging to align when welding and assembling, and the cost is tremendously cheap, so it has been substantially used.

Product specs DN10-DN2000

Flat welding flanges are no longer allowed to be applicable now welded with tees, elbows and one-of-a-kind pipe fittings, and straighten pipe sections are required.
