American standard flange production process with neck flat welding: saw cutting, heat treatment, die forging, machining;

American standard with neck flat welded flange implementation standard

ANSI B16.5, ANSI B16.47, MSS SP44, ANSI B16.36, ANSI B16.48;

1: The American standard neck flush welding flange is connected to the pipe end.A part that connects a pipe to a pipe.

2: American standard neck flat welding flange has holes, can be threaded bolts, so that the two flanges are tightly connected, between the flanges with gasket sealing.

3: American standard neck flush flange connection refers to a pair of flanges, a gasket and a number of bolts and nuts.

4: The gasket is placed between the sealing surface of two flanges. After tightening the nut, the specific pressure on the surface of the gasket reaches a certain value and generates deformation, and fills the uneven place on the sealing surface, so that the connection is tight without leakage.The flange connection is a detachable connection.According to the connected parts can be divided into container flange and pipe flange.Neck flush welding flange is suitable for pipe connection with nominal pressure not exceeding 2.5MPa.

5: American standard neck flat welding flange is used for the butt welding of flanges and pipes, with reasonable structure, large strength and stiffness, which can withstand high temperature and high pressure, repeated bending and temperature fluctuation, and reliable sealing.Flat welding flange with neck with nominal pressure of 0.25 ~ 2.5MPa adopts concave and convex sealing surface.

American standard flange is the part that connects the pipe to the pipe, connected to the pipe end.American standard butt welding flanges are made by forging and cast.

American standard butt welding flange can be divided into American standard butt welding flange with and without neck according to the condition of neck.

American standard butt welding flanges consist of two flanges with flange pads bolted together to complete the connection.American standard flanges are perforated and bolted together.
