Dim. Chart of black iron pipe bushing
Main points of black iron pipe bushing
The equipments from DISA Denmark, DJ AMF Japan, SINTOKOGIO Japan
widely used in our malleable iron bushing product line, ensures the
stability of product quality.
The material’s quality of the cast steel sample needs to be
examined by Oxford Instruments’s.
High heat value natural gas annealing oven will be applied to
control the annealing operation and raise the material’s physical performance.
Every pipe fitting bushing will be checked by air-tight test to
ensure zero leakage.
Why rusting happens ?
Rusting is such a common problem that it is quite easily
recognizable. Rust (Ferrous Oxide, Fe2O3, and Ferric Oxide, Fe3O4)
is an orange colored surface coating, ranging in texture from scaly
to powdery. It is loosely bound and the outer layers will usually
come off when rubbed by hand or brushed against. It is not a
deposit on the surface. Rust is the result of the combination of
the iron (Fe) with oxygen (O) in the air, in the presence of
moisture. The presence of rust means that some original iron
material has been converted to iron oxide and irreversibly lost
from the cast iron piece.
The probability of rust occurring is generally dependent upon two
1. The degree of protection (usually a protective coating) provided
to keep moisture from contact with the metal, and
2. The degree of moisture present in the air.
