HIGH PRECISION & PRESSURE PIPE _ FUEL PIPE SERIES

Synopsis of process flow: Using high quality raw material: ST35,ST37 ST37.4 ST52.4, cold drawn, anaerobic bright heat treatment, nondestructive examination. Applicable standard: IS08535-1 (steel tubes for high pressure fuel pipe in compression ignition engine), IS00404-1992 (technical requirements for steel and steel product), IS06892-1984 (tensile testing for metal). Main feasure: High precision, excellent brightness, after heat treatment, steel tube inside and outside wall have no oxide layer, high cleanness inner surface, flushing the inner diameter, anti-rust oil painted. Total impurity<1.5mg/g. Maximun granule 8 degree(^0.2mm). Under high pressure, no deformation after cold bending, the complicated geometrical forming and machining can be realized. […]
