The China welded pipes market in 2026 remains one of the most important sourcing channels for global buyers who need cost-effective, stable and customizable steel pipe products. From construction frames and machinery structures to automotive components, furniture tubes, fluid transfer systems and industrial fabrication, welded steel pipes continue to offer a strong balance between price, availability and performance.
For importers, distributors, OEM manufacturers and engineering buyers, understanding ERW pipe price, welded pipe standards, material grades and supplier capabilities is essential before placing an order. A low quotation may look attractive at first, but the real value comes from stable welding quality, accurate dimensions, reliable inspection, proper packaging and long-term supply consistency.
As a welded pipe manufacturer in China, Fengdie Metal supplies straight seam welded pipe, precision steel tubes, hydraulic cylinder tubes and custom metal tube solutions for global industrial buyers.
A welded pipe is produced by forming steel strip or steel plate into a round, square or rectangular tube shape, then welding the seam along the pipe length. Among different welded pipe types, ERW steel pipe is one of the most widely used options in the global market.
ERW means Electric Resistance Welded. During production, steel coil is uncoiled, leveled, roll-formed, high-frequency welded, sized, straightened, cut and inspected. This efficient manufacturing process makes ERW pipe suitable for buyers who need stable dimensions, clean surface, fast delivery and competitive pricing.
Common welded pipe types include:
| Type | Name | Applications |
| ERW Pipe | Electric Resistance Welded Pipe | Machinery, structure, furniture, automotive parts, low-pressure fluid |
| Straight Seam Welded Pipe | Longitudinal welded pipe | General industrial pipe, equipment frame, structural tube |
| LSAW Pipe | Longitudinal Submerged Arc Welded Pipe | Large-diameter pipeline, heavy structure |
| SSAW Pipe | Spiral Submerged Arc Welded Pipe | Water pipeline, piling, infrastructure projects |
| Standard | Typical Pipe Type | Application |
| ASTM A53 | Welded and seamless steel pipe | General pipe, mechanical and pressure-related use |
| ASTM A500 | Cold-formed welded and seamless structural tubing | Building structure, frames, machinery |
| API 5L | Seamless and welded line pipe | Oil, gas and pipeline transportation |
| EN 10219 | Cold-formed welded structural hollow section | Construction, steel structure, industrial frames |
| EN 10305 | Precision steel tubes | Automotive, hydraulic and mechanical components |
| GB/T 3091 | Welded steel pipe | Low-pressure fluid and general use |
For structural applications, ASTM A500 and EN 10219 are commonly requested. For oil and gas pipeline applications, API 5L is often used. For general industrial welded pipe, buyers may also choose ASTM A53, GB/T 3091 or custom technical specifications according to the final application.
If your application involves hydraulic cylinders, high inner surface requirements or tighter ID tolerance, hydraulic cylinder honed tube may be a better choice than ordinary welded pipe.
Many buyers compare ERW pipe with seamless steel tube before placing an order. The right choice depends on pressure level, precision requirement, application and budget.
| Item | ERW Welded Pipe | Seamless Steel Tube |
| Manufacturing | Steel coil forming and welding | Piercing, rolling, cold drawing or cold rolling |
| Cost | Usually more economical | Usually higher |
| Delivery | Faster for common sizes | May be longer for special sizes |
| Pressure resistance | Suitable for many medium and low-pressure uses | Better for high-pressure or critical applications |
| Precision | Good for structural and general mechanical use | Better after cold drawing or cold rolling |
| Best use | Frames, structures, furniture, general pipe, machinery | Hydraulic, automotive, high-pressure and precision components |
If your project needs cost control and standard structural performance, ERW welded pipe is often the better option. If your project requires tighter tolerances, high pressure resistance or precision assembly, precision seamless steel tube is more suitable.
Welded steel pipe is widely used because it is economical, easy to process and available in many specifications.
| Industry | Application |
| Construction | Steel structure, frame, handrail, scaffolding |
| Machinery | Equipment frame, roller tube, support tube |
| Automotive | Seat frame, structural components, tube parts |
| Agriculture | Greenhouse tube, machinery frame, irrigation support |
| Furniture | Metal chairs, tables, racks, shelves |
| Fluid transfer | Low-pressure water, air and general fluid pipe |
| Industrial fabrication | Cutting, bending, welding and assembly parts |
For automotive or suspension-related projects, buyers can also review Fengdie Metal’s premium shock absorber solutions, especially when welded or precision tubes need to match damping components and OEM assembly requirements.
Choosing the right welded pipe manufacturer China is not just about comparing price. A reliable supplier should control raw material, welding seam quality, pipe size, straightness, surface finish and final packaging.
Before placing an order, buyers should check:
Can the factory produce the required OD, wall thickness and length?
Can the supplier match the requested steel grade and standard?
Is the welding seam inspected properly?
Can the surface treatment meet the final application?
Does the supplier provide MTC and export documents?
Can the factory support cutting, chamfering, drilling or bending?
Does the supplier understand your industry application?
A good China welded pipe factory should ask about the end use before quoting. A pipe used for furniture, construction, machinery, hydraulic equipment or fluid transfer may look similar, but the technical requirements can be very different.

In most common sizes and applications, ERW pipe is more economical than seamless pipe because it uses steel coil forming and high-frequency welding, which provides higher production efficiency. However, the final ERW pipe price still depends on steel grade, wall thickness, quantity, tolerance and surface treatment.
ERW pipe is produced by electric resistance welding. Straight seam welded pipe refers to a pipe with a longitudinal weld seam. Many ERW pipes are straight seam welded pipes, but the term “straight seam welded pipe” can also include other longitudinal welding processes.
For structural use, ASTM A500 or EN 10219 may be suitable. For general pipe applications, ASTM A53 or GB/T 3091 may be used. For pipeline applications, API 5L is commonly requested. The correct standard depends on the project application and buyer market.
Yes. A welded pipe manufacturer can customize outside diameter, wall thickness, length, surface treatment, cutting, chamfering, drilling, bending and packaging according to buyer drawings.
Send your pipe size, wall thickness, grade, standard, quantity, surface treatment, application and destination port. This helps the supplier calculate material cost, processing cost, packaging and freight more accurately.
If your project requires high pressure resistance, tighter tolerance, hydraulic cylinder use or critical mechanical performance, seamless steel tube may be more suitable. You can compare welded pipe with precision seamless steel tube before confirming the order.
