Introduction

What is precision pipe

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.

Standard

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.
Features
a.You can get a smaller diameter with precision steel pipe
b. High precision pipe accept small quantity for MOQ.
c. The pipes with cold drawn processes has high precision and good surface finish.
d. The transverse area of the steel pipe is more complicated.
e. Performance is superior, with higher density.

Packing

There are probably hundreds of different methods for packing a pipe, and most of them have merit, but there are two principles that are vital for any method to work prevent rusting and Sea transportation security.Our packing can meet any needs of the customers.

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.
