Carbon steel pipes are pipeline systems made of carbon steel (with a carbon content of 0.08% -2.11%) as the substrate, which are formed through welding or seamless processes and widely used for transporting fluids, gases, or solid particulate media. According to carbon content, carbon steel can be divided into low carbon steel (such as 10 # and 20 # steel), medium carbon steel (such as 45 # steel), and high carbon steel.

Seamless steel pipe: no welds, suitable for high-pressure and high-temperature scenarios (such as cracking furnace tubes in oil refineries);

Welded steel pipe: High frequency resistance welding (ERW) or submerged arc welding (SAW), low cost, suitable for low-pressure fluid transportation (such as urban gas pipelines).

1. Energy industry

Oil and gas: onshore/subsea pipelines (API 5L X65/X70 steel grade);
Electricity: Main steam pipeline of thermal power plant (ASTM A335 P91, high temperature creep resistance);
Hydrogen energy: Hydrogen gas transmission pipeline (requiring anti hydrogen embrittlement material design).

2. Chemical and Industrial

Corrosive medium transportation (requires lining with anti-corrosion layer, such as epoxy resin coating);
Heat exchanger pipeline (resistant to temperature difference stress, such as boiler feedwater preheater).

3. Construction Engineering

Fire sprinkler system (galvanized carbon steel pipe rust prevention);
HVAC pipeline network (with insulation materials to reduce heat loss).
