Product Description

Flat Welded Flange / Plate Flange

These flat welding flanges are GOST, ASME B16.5 flat welding flange, ASME B16.47 flat welding flange, DIN 2634 flat welding flange, DIN 2635 flat welding flange, DIN 2630 flat welding flange, DIN 2636 flat welding method Flanges, DIN 2631 flat welding flanges, DIN 2637 flat welding flanges, etc. Flanges are parts that connect pipes to each other and are connected to pipe ends. There are holes on the flange, and bolts make the two flanges tightly connected. Gaskets are used to seal between flanges. Flat welding flanges are suitable for steel pipe connections with a nominal pressure not exceeding 2.5MPa. The sealing surfaces of flat welding flanges can be made of smooth, concave-convex and tongue-and-groove types.

Size Flat welding flange: 3/8"~40" (DN10~DN1000)

Pressure American series: CLASS 150, CLASS 300, CLASS 400, CLASS 600, CLASS 900, CLASS 1500, CLASS 2500
European series: PN 2.5, PN 6, PN 10, PN 16, PN 25, PN 40, PN 63, PN 100, PN 160, PN 250, PN 320, PN 400

Butt Welding Flange / Weld Neck Flange / WN Flange

It refers to a flange with a neck and a round pipe transition and butt welding connection with the pipe. We produce ASME B16.5 butt welding flanges, GOST12820, GOST12821, GOST33259, ASME B16.47 butt welding flanges, DIN 2631 butt welding flanges Welding flanges, DIN 2637 butt welding flanges, DIN 2632 butt welding flanges, DIN 2638 butt welding flanges, DIN 2633 butt welding flanges, etc. Welding flanges are suitable for pipelines with large fluctuations in pressure or temperature or high temperature, High pressure and low temperature pipelines are also used for pipelines that transport expensive, flammable and explosive media. Butt welding flanges are not easily deformed, have good sealing, and are widely used.
