Leyon piping system co.,ltd ,who specialized in piping fittings more than 22 years,and built long term cooperation with more than 90 countries customers,our products main applications are : plumbing,water supplying for drinking water and fire fighting etc.
Production Processing for malleable pipe fittings
We buy and use dense ,high strength ,nonporous iron and steel scrap
as raw material .Because that is basic point on excellent malleable pipe fittings
Thread processed is exactly based on ASME EN BS DIN standard requirements,
so that make every thread of malleable pipe fittings can be matched easily.
Pipe fittings size of malleable pipe fittings from 1/8 "to 8".
Favorable tenacity,long service life for malleable pipe fittings
Smooth surface without any sand hole on malleable pipe fittings
zinc coating’s average thickness of malleable pipe fittings
is higher than 86 um, which is specified in ASME, EN(70um), DIN(70um) and SI(78um).

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.
