Product Description
Carbon steel pipe can be divided into seamless steel pipe, straight
steel pipe, spiral steel pipe, high frequency welded steel pipe and
so on.Carbon steel seamless steel pipe is a kind of long steel.
The pipe has a hollow section and is used in a large number of
pipelines for fluid transportation, such as those for oil, natural
gas, gas, water and some solid materials.

Seamless pipe production procedure and methods:
1. Hot rolled seamless steel pipe
using hot rolled steel pipe billet to make heating and piercing,
elongating, sizing and stranghtening, cooling, finally hollow bars
finished, this is the type most commonly used. Because it is hot
rolled, so cost is lowest, but it is suit for large quantity, for
small quantity, have to make cold drawn or round bar piercing.
size: outer diameter 15mm- 499mm, wall thickness 2mm- 80mm
2. Cold drawn seamless steel pipe
for outer diameter not over than 63.5mm, small size hollow bar,
when demanded quantity is under 5 tons, usually make cold drawn
hollow bar, using larger size hot rolled hollow bar to draw to the
size demanded.
some size can be finished only by one time drawing, but some other
sizes might need twice or three times to finish drawing, it takes
time, so the cost is higher.
cold drawn size outer diameter 16mm- 63.5mm
3. Hot- expanding seamless steel piper
For hollow bar sizes are special, not common sizes, have to use
smaller thick wall hollow bar to hot expand to be larger size
hollow bar, but the technical property for hot-expanded hollow bar
will be lower than the original hollow bar. Size: outer diameter
over 356mm.

Applications:
Rolling seamless carbon steel pipe is divided into hot rolling and
cold rolling (drawing) pipe.
Hot rolled carbon steel pipe is divided into general steel pipe,
low and medium pressure boiler pipe, high pressure boiler pipe,
alloy pipe, stainless steel pipe, petroleum cracking pipe,
geological pipe and other steel pipe, etc.
Cold rolled (dial) carbon steel pipes include general steel pipe,
low-medium pressure boiler steel pipe, high-pressure boiler steel
pipe, alloy steel pipe, stainless steel pipe, petroleum cracking
pipe, and other steel pipe, including carbon thin-walled steel
pipe, alloy thin-walled steel pipe, stainless steel pipe, and
special-shaped steel pipe.
Oil pipe mainly used for transport oil and gas,and also widely used
as transmission fluid pipe,
such as transport oil, natural gas, coal gas, water and some solid
pipeline etc.
