China remains one of the world’s most important manufacturing and export bases for welded steel pipe. In 2026, international buyers continue to source Chinese ERW pipe, black welded pipe, galvanized pipe, structural tubing and precision welded tube for construction, machinery, automotive components, water systems and energy projects.
The market, however, cannot be understood through one headline price. The final China ERW pipe price per ton depends on the steel grade, outside diameter, wall thickness, standard, coating, testing, order weight and delivery term. A low offer may exclude galvanizing, non-destructive testing, end machining, export packing or even the correct wall-thickness tolerance.
This 2026 guide explains the market direction, realistic price references, major welded pipe standards and the steps buyers should follow when comparing a China welded steel pipe manufacturer.
The 2026 Chinese welded pipe market is defined by competitive export supply, restrained domestic construction demand and continued purchasing from infrastructure and industrial markets.
China exported approximately 6.20 million metric tons of welded pipe in 2025, up from about 5.33 million tons in 2024. That represents growth of roughly 16.3% year on year, according to data reported by CEIC from China’s National Bureau of Statistics. The increase confirms that welded pipe mills have been relying more heavily on export business.
At the same time, China’s total crude steel output declined in 2025, and first-half 2026 output was also lower year on year. Domestic property construction remained weak, while manufacturing, infrastructure, energy and overseas projects provided more resilient areas of demand. This combination has kept Chinese mills export-oriented and prices broadly competitive.
ERW means electric resistance welded. Steel coil is slit, progressively formed into a tube and joined along the longitudinal seam by resistance heating and pressure. Modern high-frequency welding, online inspection, bead removal and sizing provide efficient production and stable dimensions.
ERW products are commonly used for:
water, air and low- to medium-pressure lines;
construction and structural components;
fencing, scaffolding and agricultural equipment;
automotive and motorcycle parts;
furniture, machinery and fabricated components.
See Fengdie’s straight seam ERW welded pipe product page for available dimensions and processing options.
| Pipe Type | Manufactyring Route | Typical Use | Main Advantage |
| ERW / HFW | Coil formed and resistance welded along a straight seam | Mechanical, structural and fluid-service pipe | Efficient output, stable dimensions and competitive cost |
| LSAW | Plate formed and submerged-arc welded longitudinally | Large-diameter, thick-wall line pipe | Suitable for large diameters and demanding pressure service |
| SSAW / HSAW | Coil formed helically and submerged-arc welded | Water transmission and piling | Flexible large-diameter production from coil |
| Seamless | Billet pierced and rolled/drawn without a seam | High-pressure, high-temperature or critical service | No longitudinal weld seam |
ERW is not automatically inferior to seamless pipe. Selection depends on the governing standard, pressure, temperature, fatigue conditions and engineering approval. For applications requiring a seamless structure and very tight tolerances, compare Fengdie’s precision seamless steel tubes.
Tell the manufacturer whether the tube is for pressure service, structural fabrication, automotive components, machining or general conveyance. The application determines the correct grade, tolerance and test package.
Check the production-line size range, raw-material sources, welding method, in-house and outsourced processes, testing equipment, monthly capacity and current lead time. Ask the supplier for live production evidence linked to the order rather than relying only on a generic factory video.
Before production, review the technical data sheet, tolerance table, sample mill certificate, inspection plan and packaging requirements. Fengdie describes its process controls on its steel tube quality control page.
For custom precision tube, approve a sample or first article. Before shipment, verify dimensions, quantity, marking, surface, coating, test records and container loading. Critical orders may use SGS, Bureau Veritas, TÜV or another agreed inspection company.
A reliable ERW pipe factory should match its inspection plan to the product standard and service:
raw-material chemistry and heat-number traceability;
strip thickness and width measurement;
weld-parameter and weld-bead control;
OD, wall thickness, ovality and straightness inspection;
eddy-current or ultrasonic weld inspection where required;
flattening, flaring, tensile or bend tests where specified;
hydrostatic testing for applicable pressure pipe;
coating, marking, packing and certificate review.
Avoid treating Q235B, ASTM A53 Grade B and S235 as automatically interchangeable. A manufacturer must compare chemistry, strength, dimensions, testing and certificate requirements before substitution.
Changzhou Fengdie Metal Technology Co., Ltd. is a China-based precision steel tube supplier serving automotive, machinery, hydraulic and industrial buyers. Its core offering includes carbon and stainless welded tubes, custom dimensions and downstream processing.
According to Fengdie’s current production information, the listed precision welded range includes:
approximately 15–90 mm outside diameter;
approximately 1–5 mm wall thickness;
carbon steel and stainless steel options;
custom cutting, chamfering and CNC processing;
inspection documentation and export packaging.
Buyers should submit the standard, grade, OD, wall thickness, tolerance, annual demand and destination so the manufacturer team can confirm feasibility. Learn more from the Fengdie Metal factory profile, or request a welded pipe quotation.
Mainstream mid-2026 carbon steel ERW pipe price references were broadly around USD 540–600/MT FOB China. Actual offers depend on grade, size, standard, coating, testing, quantity and delivery term.
Welded pipe is the broader category. ERW is one process in which formed steel strip is joined along a longitudinal seam using resistance heating and pressure. LSAW and SSAW are other welded pipe processes.
ERW is generally more economical for comparable standard sizes because it is produced efficiently from coil. Seamless pipe may still be required for high-pressure, high-temperature or critical service.
Use API 5L for oil and gas line pipe, ASTM A53 for relevant mechanical and pressure service, ASTM A500 or EN 10219 for structures, ASTM A513 for mechanical tubing and EN 10305-2 for welded precision tube.
No. They are controlled by different standards and are not automatically interchangeable. Compare chemistry, mechanical properties, dimensions, testing and certification before approving a replacement.
Many export-oriented mills can provide an EN 10204 3.1 mill test certificate when it is specified in the order. Review a sample certificate and confirm heat-number traceability before production.
Provide the standard, grade, OD, wall thickness, length, tolerance, surface, ends, weld-bead requirement, testing, certificate, quantity, destination and Incoterm. Include a drawing for precision mechanical tubing.
