Seamless Steel Pipe:
The seamless steel pipe is made of perforated whole round steel,
and the steel pipe without weld seam on the surface is called
seamless steel pipe. According to the production method, seamless
steel pipes can be divided into hot-rolled seamless steel pipes,
cold-rolled seamless steel pipes, cold-drawn seamless steel pipes,
extruded seamless steel pipes, and pipe jacking.
Pipeline steel pipe is a specially treated steel pipe with many
excellent performance and use characteristics. It is widely used in
various industrial and civil fields, providing important support
for social development and people's lives. The main uses of
pipeline steel pipes will be introduced in detail below.
First of all, pipeline steel pipes are widely used to transport
liquids. For example, oil, natural gas, water and other liquids are
transported and distributed to various places through the pipeline
system, which includes a large number of pipeline steel pipes.
Pipeline systems usually need to withstand high pressure and
temperature, and pipeline steel pipes have good pressure and
temperature resistance, and can transport various liquids safely
and reliably.
Secondly, pipeline steel pipes are also widely used to transport
gas. Many chemical plants and energy companies use pipeline systems
to transport gases, including hydrogen, oxygen, nitrogen, and more.
These gases also need to withstand high pressure and temperature
during transportation, so high-strength and corrosion-resistant
pipeline steel pipes are required.
