Mild Steel Welded Pipe is a general-purpose welded steel tube manufactured from low-carbon(mild)steel plates or coils.The material is formed into a round shape and welded longitudinally or spirally using processes such as ERW,HFW,or SAW.It is economical,easy to fabricate,and widely applied in low-pressure fluid conveyance and general structural applications.
Key Features
Low carbon content:Good weldability,ductility,and formability.
Cost-efficient:Lower material and production cost compared to alloy or seamless steel pipes.
Easy to machine:Can be cut,drilled,bent,threaded,and welded on-site.
Smooth surface and consistent dimensions:Suitable for assembly and installation.
Available in various sizes:From small-diameter pipes to large-diameter structural tubes.
Common Manufacturing Processes
ERW/HFW:For small and medium diameters,high production speed,tight tolerances.
SAW(LSAW&SSAW):For large-diameter,thick-wall pipes used in heavier applications.
Typical Materials&Standards
Materials:Q235,Q195,ST37,S235JR,A36,ASTM A53 Grade A/B
Standards:ASTM A53,EN 10217,GB/T 3091,BS 1387
Main Applications
Water supply and drainage pipelines
Gas and low-pressure fluid transportation
Scaffolding pipes
Structural steel works,support columns,and pipe piles
Fencing,handrails,and general engineering
HVAC and ventilation ducting
Advantages
Affordable and widely available
Excellent weldability and workability
Suitable for non-critical pressure systems
Ideal for mass construction and industrial projects
