Products Details

Product Description

Plate flat welding flange refers to the flange that inserts the pipe into the inner ring of the flange for welding. The flat welding flange is divided into two typesHubbed Slip On Flange and Plate Flange for Welding

Plate flat welding flange is the most common flange, which is easy to obtain materials, simple to manufacture, low cost and widely used; However, due to its poor rigidity, it shall not be used in chemical process piping systems with requirements of supply and demand, flammability, explosion and high vacuum, or in highly hazardous situations.

Product category: full face plate flange (FF), raised face plate flange (RF)

Welding form: plate type flat welding flange is used to insert the pipe into the flange for welding.

Manufacturing materials: 304, 316, 304L, 316L, 2025, 409L, 202, 321, Q235, 16MN, etc

Scope of application

Plate flat welding flange has good comprehensive performance, so it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, water heating, fire protection, electric power, aerospace, shipbuilding, etc

Product features: beautiful appearance, smooth surface, acid and alkali resistance, corrosion resistance, strong texture performance.

Technical conditions

 

The pressure marks specified in this standard are divided into PN mark and Class mark.
PN is marked with 12 pressure classes
PN2.5 respectively; PN6; PN10; PN16; PN25; PN40; PN63; PN100; PN160; PN250; PN320; PN400
Class is marked with 6 pressure classes
They are: Class 150; Class 300; Class 600; Class 900; Class 1500; Class 2500

Application technical parameters

The types of sealing surfaces of flat welding flanges are as follows:Convex convex surface (MFM) DN1300~3000 DN300~3000 DN400~2000 DN300~800
Grooved surface (TG) DN1300~3000 DN300~3000 DN300~3000 DN300~800
Full plane (FF) DN300~3000 DN300~3000 DN300~3000 DN300~800
