Low carbon steel pipe is carbon steel with a carbon content of less than 0.25%. It is also called mild steel because of its low strength, low hardness and softness. It includes most ordinary carbon structural steel and some high-quality carbon structural steel. Most of them are used for engineering structural parts without heat treatment, and some are used for mechanical parts requiring wear resistance after carburizing and other heat treatments. There are many types of materials for low carbon steel pipes, the main ones are as follows:

 

Q195 steel pipe: Low carbon, low manganese and silicon content, good plasticity and toughness, suitable for manufacturing steel pipes for general use under low load.

Q215 steel pipe: Low carbon, moderate manganese and silicon content, slightly higher strength than Q195, suitable for use under general load.

Q235 steel pipe: Low carbon, manganese, and silicon content are similar to Q215. It has good mechanical properties and processing performance, and has wide applicability.

Q345 steel pipe: Increased manganese and silicon content, higher strength than Q235, suitable for occasions with higher load and high wear resistance requirements.

 

Introduction to commonly used low carbon steel pipe materials and application fields:

Q195 steel pipe is a commonly used low carbon steel pipe material. It has good plasticity and toughness and is suitable for manufacturing general-purpose low-load steel pipes, flexible pipes, welded pipes, vertical pipes, water and gas pipes, etc. It is widely used in construction, machinery, electric power, chemical industry, agriculture, urban infrastructure and other fields. Q235 steel pipe is a commonly used low carbon steel pipe material with high strength and plasticity. It is suitable for manufacturing general structural steel pipes, flexible pipes, welded pipes, pipes for machinery manufacturing, etc. It is widely used in construction, machinery, electric power, chemical industry and other fields. 20# steel pipe is a low carbon steel pipe material, mainly composed of five elements: C, Si, Mn, S, and P. It has low strength and good surface finish. It is usually used to manufacture mechanical parts, automobile parts, and boiler pipes. wait. It is widely used in automobile, aviation, shipbuilding, petroleum and other industrial fields.

Carbon steel piping provides safety and durability. Because it is shock resistant and not affected by harsh environmental conditions like pressure or extreme weather, it is an ideal material for structural applications.

Because it’s easy to manufacture, carbonsteel piping is a versatile material. We can make it in a variety of thicknesses and dimensions. It’s also easy to cut and bent tofit wherever it's needed. It's also easily connected to joints, valves, and other pipe fittings.
