Comparison table of equal Malleable Pipe Fittings swage nipple
BSPP Equal Malleable Pipe Fittings Swage Bs Thread Gas Reducing
- In order to ensure the product quality,our malleable iron nipple
product-line is equipped with the DISA from Denmark,DJ AMF form
Japan and the automatic production line from Sinto.
- We apply the Spectrometer from Oxford Instruments to check the the
cast steel sample’s material quality.
In order to command the annealing operation grimly and improve the
physical properties of materials,we use the gas annealing furnace
of high calorific value.
To prevent leakage,we require every pipe fitting nipple needs to be
tested by air-tight test.
Controlling calibre of the thread,parallelism,angle and tooth
type,each nipple will be examined by ring gauge.
Pouring molten iron into box of pipe fitting , let it cool down and become the casting for rough casting . During casting , the temperature of molten iron , riser control all have great influence on the quality of pipe fittings . If not control well , then there are lots of problem like loose.
