BS Threaded Black Galvnized Elbow Malleable Iron Pipe Fitting Degree
State of the art equipments with automatic production line, making
high-quality products efficiently.
The brand of spectrometer we choose Oxford Instruments to examine
/analysis the quality of malleable iron samples.
Using high calorific value of natural gas annealing furnace,
strictly control the annealing process to improve the physical
properties of materials.
we use close-grained, high strength, impeccable steel & plate
scrap as the raw material, because the quality of the steel is the
starting point of the fittings of excllent quality
Accurate thread according to strict standards, ASME, EN, BS, DIN
and so on. The thread has a precise structure, the effective length
and straightness of the thread are easily engaged with the threaded
pipe.
The pipe fittings outlet size are from 1/8’’ to 8”

What are the components inside the BS Threaded Elbow Galv. Galvnized Elbow ?
There are five important components of malleable cast iron like Carbon ,Slicion, Manganese, Sulfur , Phosphorus . wC=2.2-2.8%,wSi=1.2-1.8%, wMn=0.4-1.2%, wP=0.1%, wS=0.2%
Carbon is a graphitizing element,Silicon promotes graphitization,When the content is high, it reacts,Sulfur hindered graphitization,Manganese also hindered the graphitization,so manganese also is important . Phosphorus generally has little effect,but the content is too high, will reduce the toughness of pipe fittings.
