Black Flanges 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.

Specification

Standard: GB / ANSI /JIS / DIN

Material: Ductile iron

Technics: Stamping and Welding

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.When the above conditions are met, the bolt connection between the flange plates shall be carried out.When the bracket is placed high, the flange shall not be connected with the heavy pipe.

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.
