Produce method: shall be manufactured from unalloyed quality steel or an equivalent steel produced by a steel-making process that ensures a very homogeneous structure.
The final reduction of the tube shall be followed by treatment to achieve the specified mechanical properties. Please advise.
Characteristic:Precision,Smooth finish,Cleanliness,High mechanical properties.
Delivery condition: NBK/GBK.
Inside diameter ,d
d≤4mm:±0.05mm for class2 (for diesel (compression-ignition)engines)
±0.025mm for class 1(for fuel injection pump testing)
For Class 1 and Class2 Please refer above explain.
The maximum value of the concentricity of the tube outside diameter relative to inside diameter shall be proportional to the wall thickness, as shown in Figure1.
