1, The equipments from DISA Denmark, DJ AMF Japan, SINTOKOGIO Japan widely used in our malleable iron socket productline, ensures the stability of product quality.

2, We use spectrometer from Oxford Instruments to check the material's quality

3, We use high heat value natural gas annealing furnace, strictly control the annealing process, improve the physical properties of the materials

4, Each pipe fitting socket after air tightness test, ensure no leakage

5, Strictly control the calibre of the thread, parallelism, Angle, tooth type, each live over a plug gauge for testing

6, The pipe fittings have outlets ranging from 1/8” through 6”

7, Good toughness with long working life.
