Why the producer use the production line from DISA Denmark, DJ AMF Japan, SINTOKOGIO Japan ? Because we want to make sure the quality of the goods are ok .
We apply the Spectrometer from Oxford Instruments to check the the cast steel sample’s material quality.
We use high heat value natural gas annealing furnace, strictly control the annealing process, improve the physical properties of the materials.
Each pipe fitting nipple after air tightness test, ensure no leakage.
In order to control the calibre,parallelism, angle and tooth type of the thread strictly,each pipe fitting plug needs to be checked by plug gauge test.
The outlet size for malleable iron pipe fittings swage nipple is from 1/8” to 6”.
Good toughness with long working life.
The surface is smooth without any sand hole on malleable iron pipe fittings swage nipple.
Avg. thickness of zinc coating is higher than 86 um specified in ASME, EN(70um), DIN(70um), SI(78um) is basic demand for the products.
