Quality:

Surface quality:very smooth and bright without oxide scale,pock,strach,crack and other defects. Surface roughness:Ra:0.8-1.3 um. Straightness:0.5-1mm/1000mm. Internal hole Cleaness:clean without iron scrap,dust. Mechanical Properties:better extending rate and strength property,after bending with no deformation,after flattening and flaring process with no crack. Raw material: Precision tubes are made from carbon steel from quality Bao Steel,XingCheng Steel,and HuaiSteel.

Synopsis of Process Routing: Quality Carbon steel — Cold Drawn — Heat Treatment Without Oxidization (NBK Status) — Nondestructive Testing— Flushing The Internal Hole With Special Equipment Under The High Pressure —Dealing With Antirust Oil On Surface — Plastic Capping On Both Ends.

Application:

Our carbon steel tubes are used in hydraulic system,automobile,mechanical parts and in the occasion where the high precision,brightness,cleanness and mechanical properties of the tube are required.
