Ordinary Carbon Steel Pipes
Ordinary carbon steel pipes are characterized by low carbon content, low strength, and good weldability. The main materials used in China factories are: Q195, Q215, Q235B, Q235D, 10#, 20#, and ASTM A53 Gr.B.
Leading Ordinary Carbon Steel Pipes, a source manufacturer, supports custom-length cutting, pipe beveling, threading/threading, beveling, internal and external anti-corrosion painting, hot-dip galvanizing/cold galvanizing, 3PE anti-corrosion, flaring/reducing, bending, hydrostatic testing, non-destructive testing, bundling and packaging, and export fumigation and customs clearance.

Typical Application Cases
1.Municipal Engineering: Q235B welded pipes are used for urban water supply and drainage, and residential fire protection main pipelines.
2Building Construction: Q195/Q235B ordinary carbon steel pipes are used as scaffolding and steel structure support columns.
3.Low Temperature Projects: Q235D low temperature resistant pipes are selected for outdoor pipeline networks in Northeast and Northwest China.
4.Export Projects: A53 Gr.B steel pipes are exported to Southeast Asia and Africa for municipal water supply.
5.Industrial Support: 20# seamless pipes are used for air compressor pipelines and central air conditioning water circulation systems.
