Ductile Iron Threaded Fittings

Description


Ductile iron is a kind of high-strength cast iron material developed in 1950s. Its comprehensive properties are close to that of steel. Based on its excellent properties.It has been successfully used to cast some parts with complex stress, high strength, toughness and wear resistance.

Ductile iron has developed rapidly into a widely used cast iron material next to grey cast iron. The so-called "iron for steel" mainly refers to ductile iron. Spheroidal graphite is obtained by spheroidizing and inoculation treatment, which effectively improves the mechanical properties of cast iron.Especially the plasticity and toughness, so as to obtain higher strength than carbon steel.

Flange, also known as  flange plate or flange, is the part connecting shaft and shaft, which is used for the connection between pipe ends. It is also used for the flange on the inlet and outlet of equipment, which is used for the connection between two equipment. There are holes on the flange, the bolts make the two flanges tightly connected, and the flange is sealed with gasket.

Characteristic


Ductile iron pipe fittings with ductile iron flange connecting ductile iron pipes. The three-way flange has a main pipe and a branch pipe which is perpendicular to the main pipe on one side of the main pipe and connected with the main pipe. A valve is arranged at the intersection corner of the main pipe outlet direction and the branch pipe outlet direction. A circular valve piece is arranged on the valve.

The valve piece is in the structure of mutual sealing with the inner wall of the pipe cavity in the closed state of the pipe cavity.The Ductile iron flange simplifies the pipeline setting, saves the consumption of pipeline parts, facilitates the operation, facilitates the maintenance of pipeline branch and the supply of each branch in stages.

In addition to the traditional function, the Ductile iron flange also functions as a double station valve.One of the main pipe and branch pipe output can be arbitrarily selected as a closed and the other as a smooth working state.The utility model can also arbitrarily adjust the flow ratio of the main pipe and branch pipe output, as long as the angle of the valve piece in the pipe cavity can be adjusted.

Connection method


The socket and spigot of ductile iron pipe shall be cut off, and then the external thread of pipe orifice at both ends of the pipe shall be processed. The thread pitch shall be 3mm, and the thread length shall be 3mm thicker than the cast iron flange.

For each processing of a pipe, two internal threads of cast iron flange shall be processed. After the pipe and the supporting flange are processed, the flange and the pipe shall be trial connected. It is required that the flange and the pipe thread shall be well matched and rotate flexibly without looseness.

After the processed pipe is connected with the processed flange (with internal thread), one end of the pipe shall expose the flange surface for about 3mm.After the flange connection is completed, the butt joint of the pipeline shall be carried out. During the butt joint, a rubber pad shall be added at the pipe joint, and a horizontal line of the two connected pipelines shall be ensured.

Advantage


Ductile iron flange is manufactured by EPC process, with short production cycle, high dimensional accuracy, cement lining, external spraying of anticorrosive zinc and asphalt paint, corrosion resistance and long service life. The lining is cement mortar and Portland cement.

It is coated with metallic zinc and asphalt paint. According to ISO2531 standard, the pressure is PN16. Material: nodular iron, large volume, light weight, good ductility and toughness.
