 accuracy error:(+/-0.05mm)

high precision, excellent brightness, no oxidization scale, high cleanness inner surace, flushing the inner dimeter, antirust oil painted.total impurity<1.5mg/m, maximum grangle 8 grade(</=0.2mm, withdrawn hig pressure, no deformtion after cold bending, the complicated geometrical forming and machining can be realized, color of the tube, gray with white, the tolerance for OD and ID+/-0.05mm, quality inner surface reaches to Q grade, work pressure 2000kilos, max testing pressure 6000 kilos without deformation, 180bending degree without any crack.

for high pressure fuel pipe in compression ignition engine, all tecnical requirements all reach the level of top international brand, be able to replace the imported tubes and reduce the cos for our customers.

accuracy error:(+/-0.05mm)
