Product Description:
Corresponding standards of flat welded steel pipe flange series: GB / T9119-2000,JB81-94, HGJ45-91, HG20593-97
Welding flange material: 201,304,316,316l,321,202, carbon steel, alloy steel, etc
The sealing surfaces of flange with neck are as follows: RF, FM,M, T, G, FF.
Diameter range of flat welding flange with neck: DN 100 ~ DN 600
Advantages:
flat welding flange with neck also belongs to flat welding flange, because it has a short neck, so as to improve the strength of the flange and the bearing strength of the flange. So it can be used in higher pressure pipes.
Disadvantages:
compared with flat plate flange, the cost is higher, because of its shape characteristics, it is easier to bump during transportation
