Asme B16.5 weld neck flange
| Model No. : | wn flange |
|---|---|
| Brand Name : | Bangdong |
| Standard : | BSW |
Product description
Weld Neck Flanges are drilled(machined) with the wall thickness of the flange having the same dimensions of the matching pipe, the lighter the pipe is, the larger the bore, conversely, the heavier the pipe, the small the bore, they are normally used for highpressure, cold or hot temperature.

NOTE:
1. Class 150 flanges except Lap Joint will be furnished with 0.06 (1.6mm) raised face, which is included in `Thickness` (C) and `Length through Hub` (Y1),( 56653413,Y3).
2. For Slip-on, Threaded, Socket Welding and Lap Joint Flanges, the hubs can be shaped either vertical from base to top or tapered within the limits of 7 degrees.
3. Blind Flanges may be made with the same hub as that used for Slip-on Flanges or without hub.
4. The gasket surface and backside (bearing surface for bolting) are made parallel within 1 degree. To accomplish parallelism, spot facing is carried out according to MSS SP-9, without reducing thickness (C).
5. Depth of Socket (D) is covered by ANSI B 16.5 only in sizes through 3 inch, over 3 inch is at the manufacturer`s option.

Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard.
In the production, press the mass of the forging parts, the quantity of the batch of different forging methods. Free forging productivity is low, processing surplus is large, but the tool is simple, universality is large, so it is widely-used
Forged flange is the best mechanical properties of a flange product, its raw materials are generally tube, and then after cutting and then continue to beat, to eliminate the ingot in the segregation, loose and other defects. Price and mechanical properties are higher than ordinary casting flange a grade. The flange is a part that connects the pipe with the pipe and the valve, is connected to the pipe end. It is also used for the flange on the equipment inlet and outlet.
