Seamless steel pipe VS Precision steel pipe:


1. The main feature of seamless steel pipe is that it has no welds and can withstand greater pressure. Products can be very rough as-cast or cold drawn.

2. Cold-drawn precision steel pipes are products that have appeared in recent years, mainly because the inner hole and outer wall dimensions have strict tolerances and roughness.

Features of cold drawn (rolled) precision steel pipes:

1. Smaller outer diameter
2. High precision and small batch production
3. The cold drawn (rolled) finished product has high precision and good surface quality
4. The cross-sectional area of the steel pipe is more complicated
5. The steel pipe has better performance and the metal is denser.

Main features of precision seamless steel pipe:
The inner and outer walls of the steel pipe have high precision and high smoothness. After heat treatment, the steel pipe has no oxide layer.
High cleanliness, high pressure steel pipe, no deformation after cold bending, no cracks in flaring and flattening, and can be processed for various complex deformations and machining. Steel pipe color: bright white with high metallic luster.

What is the difference between precision seamless steel pipe and cold drawn seamless steel pipe?

The precision seamless steel pipe is made by the cold rolling process of the precision cold rolling mill, and the cold drawn seamless steel pipe is made by the cold drawing method. Generally speaking, the precision, finish and size of the cold rolled pipe are better than those of the cold drawn Much better. Precision seamless steel pipe is used in automobiles, hydraulic parts, machining, mechanical parts and other users who have high requirements on the precision and finish of steel pipes. Because precision seamless steel pipes have high precision, no oxide layer, small dimensional tolerance and good finish, so Many machining users choose precision seamless steel pipes in order to save labor, material and time losses.


Tips: Mild Steel pipes (MS seamless pipe) are manufactured using low carbon (less than 0.25%) steel. As MS Pipes are made from mild steel they can easily be welded and formed in various shapes and sizes for pipelining and tubing purposes.
