Q195 Carbon Steel Pipe is a popular material used in heavy-duty industries like construction, ships, distilleries, chemical fertilizer equipment and oil fields due to its strength and longevity.

Cost-Effective – Carbon steel pipes offer the major benefit of being much cheaper than their stainless steel or aluminum counterparts, making them a cost-effective choice for many industrial settings, particularly oil fields where cost effectiveness is essential.


Specification Description
ASTM A53 Standard specification for pipe, steel, black and hot-dipped, zinc-coated, welded and seamless
GB/T 3091 Welded steel pipes for low pressure liquid delivery
GB/T 13793 Steel pipes with a longitudinal electric resistance welded (ERW) process
GB/T 6728 Cold formed steel hollow sections for general structure dimensions, shapes, weight and permissible deviations
JIS G3444 Carbon steel tubes for general structural purposes
EN 10255 Non-alloy steel tubes suitable for welding and threading. Technical delivery conditions
BS 1387 Steel tubes and tubulars suitable for screwing to BS21 pipe threads
DIN 2440 Steel tubes medium weight suitable for screwing
ISO 65 Carbon steel tubes suitable for screwing in accordance with ISO 7-1


Durability – Carbon steel offers the added advantage of being resistant to shocks and vibrations, making it ideal for structural applications like building frames.

Relatively Lightweight – Carbon steel is relatively light compared to other materials, making it easier for transport and installation. This can save time and money on installation fees.

Corrosion-Resistant – Carbon steel, an alloy composed of iron and carbon, has excellent corrosion resistance. This makes it a great option for piping applications since maintenance costs are minimal and don’t necessitate expensive treatments or chemicals.

This study utilized field emission scanning electron microscopy (FESEM) to investigate the surface modification of Q195 structure carbon steel after electrolytic plasma processing (EPP). The corresponding data are summarized in Figure 3. After 40 seconds of EPP treatment, there was a marked decrease in both elastic modulus and hardness of the sample.
