Bangdong Supply A182 F51 Flanges,A182 F304L Flanges,A182 F91 Flanges.Early carbon steel pipe producers employed a manufacturing method called butt-welding. The butt-welding process was quite elementary in that it merely rolled a piece of heated steel plate into tubular form and created a longitudinal weld through compression and direct heat. When the mill came to the end of a coil, they could simply weld it to the beginning of the next coil with little interruption to production. As industry called for tighter tolerances and better welds, the continuous butt-weld process gave way to electric resistance welding (ERW). ERW is quite similar to the continuous weld process in that coils of steel are leveled and fed down a line of forming rolls, but that is where the similarities end. During the ERW process the unrolled coils (skelp) are not heated and the longitudinal weld is created by way of an electric current. The weld is then electronically inspected for defects, normalized so as to maintain consistency with the rest of the steel, and cooled. At this point the pipe is sometimes resized and then cut, coated, and or tested to meet the desired specifications. ERW pipe typically holds much tighter tolerances and maintains surface and wall consistency much more than seamless carbon steel pipe. Common ERW specs include; API5LB, A53, and A500

Forged steel Flange are perfectly finished with precision using the latest machinery.

Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.
Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

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. Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.

The flanges are suitable for connection of steel pipes conveying mediums such as steam, oil, air and water. They are widely used in Chemical industry and Shipbuilding . And the flanges are suitable for welding.The flanges mainly include Welding Neck, Blind, Slip-on, Lap-Joint, Socket,Reducing and Plate type.

Size available: 1/2"--72"(DN15-DN1800).             

Forged steel flanges are made in seven primary ratings:

Asme B 16.5 Class 150 lb 400 lb 900lb 2500lb 300lb 600lb 1500lbcutting 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.
