Pipe Fitting Reducer Bushing Black Iron Pipe Bushing Without Any Sand Hole

1. The producer try to test every products through air tightness test , to make sure no leakage .
   
2. Ring gauge will be took to detect every union so as to master the calibre,parallelism, angle and tooth type of thread.
   
3. Pipe fittings’ exit is deterrent from 4x3”to 8x6”.
   
4. The product quality of malleable iron bushing can be well controlled by adopting the DISA from Denmark,DJ AMF form Japan and the automatic production line from Sinto .

Don't save good in humid environment:

The reason is that humidity is the second factor affecting the rate of oxidation (rusting) of iron. It is generally accepted that rusting cannot begin unless the relative humidity is at or above 65% (this figure can be lower, however, in the presence of pollutants). Relative humidity is, however, not the only factor to be considered. Once rusting has started, at least two other phenomena may occur:

1. Some rust or ferrous oxide can become hydrated, i.e. it can contain moisture within its chemical structure, thereby exposing the iron to additional moisture, and

2. The porous rust may act as a reservoir for liquid water, keeping it in contact with the iron and perpetuating the rusting process.
