Product Description
Plate flange refers to a flange connected with a container or pipe by a fillet weld. It is an arbitrary flange. According to the integrity of the connection between the flange ring and the straight barrel section, the design is checked according to the integral or loose flange. There are two kinds of flange rings with neck and without neck. Compared with the neck butt welded flange, the flat welded flange has simple structure and less material, but the stiffness and sealing property are not as good as that of the neck butt welded flange. Flat welded flange is widely used in the connection of medium and low pressure vessels and pipelines.

Flat Welding Flange (Plate Flange) - Introduction
A flat welding flange (commonly known as a plate flange or plain flange) is a type of pipe flange designed for welding to pipes, fittings, or equipment. It features a flat face and is typically used in low-pressure and non-critical applications due to its simple structure and cost-effectiveness.
Key Features:
-
Design & Connection
-
The flange has a flat sealing surface and is welded only on the outer side (no internal weld required).
-
Suitable for butt-welding to pipes, ensuring a smooth flow path.
-
-
Pressure & Temperature Range
-
Primarily used in low/medium-pressure systems (e.g., PN6-PN40/Class 150-Class 300).
-
Operating temperature usually below 300°C (dependent on material).
-
-
Materials
-
Common materials: Carbon steel (A105), stainless steel (SS304, SS316), alloy steel.
-
-
Standards
-
Complies with international standards:
-
ANSI/ASME B16.5 (USA)
-
EN 1092-1 (Europe)
-
GB/T 9119 (China)
-
-
-
Applications
-
Water treatment, HVAC systems, low-pressure pipelines, and general industrial piping.
-
Advantages:
Easy to install and weld.
Economical for low-pressure uses.
Lightweight compared to weld-neck flanges.
Limitations:
Not suitable for high-pressure/vibration environments.
Weaker structural strength than weld-neck/slip-on flanges.
For higher-pressure applications, weld-neck flanges (WN) or slip-on flanges (SO) are recommended.
