DIN2631(Carbon Steel) : ASTM A105, 20 #, Q235, 16 mn, With neck flat welding steel pipe flange ASTM A350 LF1, LF2 CL1 / CL2, LF3 CL1 / CL2, ASTM A694 F42, F46, F48, F50, F52, F56, the F60, F65, F70;

Flat welding flange is a kind of disc parts, are the most common in the pipeline engineering, the flange is used in pairs. In pipeline engineering, flat welding flange is mainly used for pipe connection. In need of connecting pipes and all kinds of installation of a flange, the low pressure pipe flange can use silk, the use of more than 4 kg pressure welding flange. By sealing point between two pieces of flange and bolt fastening. Different stress of flange bolts with different thickness and use different. When water pump and valve, and pipe connection, the local equipment, also made the corresponding flange shape, also known as flange connection. Where there are two surfaces in the surrounding use of bolt connection closed connection parts at the same time, generally referred to as the "flange", such as ventilation pipe connections, this kind of parts can be called "flange parts". But this connection is only a partial equipment, such as flange connection and water pumps, not good called the pump flange parts ". Relatively small, such as valves
