1/2 inch 3/4 inch cast iron threaded fittings Malleable Iron Tee
Leyon takes pride in its part in making the world a better place.
We thrive on the challenge, and appreciate the role we play in
enabling our customers to construct those structures, utilities and
pipelines that we sometimes take for granted.
We use spectrometer from Oxford Instruments to check the material's
quality.
We use high heat value natural gas annealing furnace, strictly
control the annealing process, improve the physical properties of
the materials
Strictly control the size of the thread, to ensure accuracy.
1/8”~8”The pipe fittings have outlets ranging from 1/8” through 8”.
Good toughness with long working life.
Smooth surface without any sand hole

What’s the different of ductile iron , gray iron and malleable cast
iron ?
The characteristic of ductile iron is very tough, graphite is in
the form of a ball.
The feature of gray iron is very brittle , graphite is in the form
of strip .
The particularity of malleable cast iron is graphite is a group of
flocculent tiles .
So the ductile iron is hardest , malleable cast iron is harder than
gray iron .
Why the the toughness of them is different ?
The big reason is time of annealing . If it annealing long time ,
then the cost also is higher and the quality also is better .
