1/4"-6" Malleable Iron Industrial Pipe Fittings , Sanitary Pipe Fittings High Tenacity

Description of the malleable iron elbow

Malleable cast iron pipe elbow processing production adopt the equipments from DISA Denmark DJ AMF Japan ,SINTOKOGIO automatic production line to guarantee the quality of the products;

The cast iron samples are used to test its material’s quality by using spectrometer from Oxford Instruments; 

Using high calorific value of natural gas annealing furnace,manipulate the annealing process rigorously,improve the physical properties of the materials;

The final casting fittings are made of close-grained,

high strength, impeccable steel & plate scrap.

Since quality of the steel is the outset of excellent quality fittings; Our accurate threads are complied with strict standard ,such as AME,EN,BS,DIN etc.

Size of elbow

The threads have an accurate structure,make sure that the thread length and straightness are easier to coincide with thread pipe; The pipe fittings outlet size are from 1/8’’ to 8”;Favorable tenacity,long service life; The surface is smooth without trachoma; The zinc average coating thickness is higher than the requirements of standard for ASME(86 um), EN(70um), DIN(70um) and SI(78um).
