Carbon steel welded pipe is a steel pipe produced by forming carbon steel strip, coil or plate into a tubular shape and welding the seam. It is widely used because of its economical cost, stable quality, strong mechanical performance and flexible size range.
Compared with seamless steel pipe, welded pipe is often more cost-effective for structural, construction, low-pressure transmission and general industrial applications. It can be supplied in round, square, rectangular or customized shapes according to the final use.
Henan GDD supplies carbon steel welded pipes for steel distributors, construction companies, structural steel factories, water project contractors, piling projects, machinery manufacturers, scaffolding suppliers and global industrial buyers.

Carbon steel welded pipe is made by rolling steel strip or steel plate into a pipe shape and welding the joint line. The welding process creates a continuous pipe body with stable dimensions and reliable strength.
According to production method and pipe size, carbon steel welded pipe can be divided into ERW pipe, high-frequency welded pipe, longitudinal submerged arc welded pipe and spiral submerged arc welded pipe. Different welded pipe types are used for different projects, from light structural tubes to large-diameter water transmission and piling pipes.
Carbon steel welded pipe can be cut, welded, threaded, drilled, painted, galvanized or coated according to project requirements. This makes it a practical choice for construction, engineering and industrial fabrication.
ERW pipe is produced by electric resistance welding. It has good dimensional accuracy, stable weld quality and high production efficiency. It is commonly used for construction structures, scaffolding, fencing, furniture frames, machinery, greenhouse structures and low-pressure fluid transmission.
LSAW pipe is produced by longitudinal submerged arc welding. It is suitable for large-diameter and thick-wall applications. It is commonly used in piling projects, bridges, steel structures, water transmission, oil and gas projects and heavy engineering applications.
SSAW pipe is produced by spiral submerged arc welding. It is widely used for large-diameter pipelines, water transmission, drainage systems, piling, bridge foundations and infrastructure projects. The spiral welding process allows flexible diameter production.
Black welded steel pipe is supplied with a natural black steel surface or light oil protection. It is often used for structural fabrication, machinery, construction, frames and general industrial purposes.
Galvanized welded pipe is coated with zinc to improve corrosion resistance. It is suitable for outdoor structures, fencing, scaffolding, greenhouse frames, handrails and general exposed environments.
Carbon steel welded pipe is widely used in construction and industrial fields. In building projects, it is used for steel structures, roof frames, columns, bracing, scaffolding, handrails, fences and temporary support systems.
For infrastructure and water projects, welded steel pipe can be used for water transmission, drainage, piling, bridge foundations, pipe piles and municipal engineering.
In manufacturing industries, carbon steel welded pipe is used for machinery frames, equipment supports, vehicle parts, racks, shelves, agricultural equipment, greenhouse structures and general welded components.
It is also suitable for fencing systems, guardrails, sign posts, industrial platforms, warehouses, factories and other projects requiring strong and economical steel pipe materials.
Carbon steel welded pipe provides reliable strength and practical processing performance at a competitive cost. It is suitable for large-volume construction and industrial projects.
Welded pipe can be supplied in small, medium and large diameters. Wall thickness, length, pipe shape and end type can be customized according to project requirements.
Carbon steel welded pipe can be welded, cut, drilled, threaded, bent and connected with fittings. It is suitable for both factory processing and on-site installation.
Black surface, oiled surface, painted surface, galvanized surface and anti-corrosion coating can be supplied according to indoor, outdoor or project-specific environments.
With suitable steel grade and production control, welded steel pipe can provide stable strength, reliable weld seam quality and consistent dimensional accuracy.
The product is widely used in construction, machinery, infrastructure, water projects, piling, scaffolding, fencing, agriculture and industrial fabrication.
ERW pipe is usually selected for small and medium diameter pipes, structural tubes, scaffolding, fencing and general fabrication. It has high production efficiency and good dimensional accuracy.
LSAW pipe is more suitable for large-diameter, thick-wall and heavy-duty applications. It is commonly used in piling, bridge construction, water transmission and major engineering projects.
SSAW pipe is suitable for large-diameter pipelines and infrastructure projects. It offers flexible diameter options and is widely used for water transmission, drainage, piling and pipe pile applications.
The best pipe type depends on diameter, wall thickness, working condition, standard, pressure requirement and project budget.
Henan GDD can supply carbon steel welded pipes with different surface treatments. Common options include black surface, light oiled surface, painted surface, galvanized surface, epoxy coating and other anti-corrosion coatings.
Pipe ends can be supplied as plain ends for general use, beveled ends for welding, threaded ends for connection, or grooved ends for mechanical joint systems. Plastic caps, bundle labels, customer marks and special export packing can also be arranged.
