Precision pipe is the carbon, alloy or stainless steel pipe with high precision sizes. Usually it has been made through hot rolling or cold drawn (cold rolling) processes. So precision pipe is a kind of seamless pipe.
It is designed with several advantages:
Inside and outside surface no oxide coating;
It could bear high pressure, no leaking;
Strict less tolerance;
Surface smooth;
No reformation in cold bending, no cracks during flaring test, and flattening test.
With these advantages it is widely used for manufacturing the pneumatic parts and hydraulic components.

International standard for precision pipe is DIN 2391, which is applied with European standard.
As a matter of fact, more steel pipe standard could applied for the precision pipe. Includes DIN2445, EN10305, DIN1630, DIN1629, ASTM A106, ASTM A179, JIS G3445
Materials available with 10#, 20#, 35, 45, 40Cr, 25Mn. 37Mn5, St35(E235), St37.4, St45(E255), St52(E355) and etc.

● Plastic caps plugged at the two sides of pipe ends

● Should be avoided by the steel strapping and transport damage

● Bundled signs should be uniform and consistent

● The same bundle(batch) of steel pipe should be came from the same furnace.

● The steel pipe has the same furnace number, the same steel grade, the same specifications.
