Flat welded flange refers to a flange that is related with a container or pipeline with the aid of way of achievable 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 handy with and barring neck. Compared with the butt welding flange with neck, the flat welding flange has a fundamental shape and saves materials, then as soon as greater the stiffness and tightness are now no longer as perfect as the butt welding flange with the neck. Flat welded flanges are appreciably used in the connection of medium and low stress vessels and pipelines.

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

Flat welded flanges are remarkable for piping constructions with low strain tiers and low stress fluctuations, vibrations and vibrations. The gain of flat welding flange is that it is plenty much less difficult to align when welding and assembling, and the charge is relatively cheap, so it has been significantly used.

Product specs DN10-DN2000

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