ERW STEEL PIPE

ERW (Electric Resistance Welded) steel pipe is manufactured by forming steel strip into a cylindrical shape and joining the longitudinal seam through electric resistance welding. It is widely used in construction, infrastructure, water transmission, mechanical applications, structural fabrication, fencing, solar structures and general industrial projects.

TEWOO supplies ERW steel pipes through qualified manufacturing partners in China, supporting international buyers with product sourcing, technical clarification, quality coordination, documentation and shipment arrangements. We review each requirement based on the applicable standard, steel grade, dimensions, quantity and application to identify suitable supply options.

When requesting a quotation, buyers are encouraged to specify the required standard, steel grade, dimensions and application so that we can confirm the most suitable supply option.

Surface Treatment

Different surface options can be considered according to the application and required corrosion protection.

Black ERW Steel Pipe
Suitable for general structural, mechanical and industrial applications where additional corrosion protection is not required.

Pre-Galvanized ERW Pipe
Suitable for applications requiring a galvanized surface and consistent coating on steel strip before pipe forming.

Hot-Dip Galvanized ERW Pipe
Suitable for applications requiring enhanced corrosion protection, including construction, fencing and outdoor structural applications.

Other coating or surface treatment requirements can be reviewed according to project specifications.

Applications of ERW Steel Pipe

ERW steel pipes are used across a wide range of industries and applications, including:

• Construction and structural fabrication

• Water and low-pressure fluid transportation

• Mechanical and industrial applications

• Fencing and guardrail structures

• Solar support structures

• General fabrication

• Infrastructure projects

• Agricultural and industrial facilities

The appropriate pipe specification depends on the operating conditions, application, applicable standard and buyer requirements.

Quality & Inspection

TEWOO coordinates quality requirements with selected manufacturing partners according to customer specifications. Depending on the order and product requirements, quality control may include material verification, dimensional inspection, wall thickness inspection, surface inspection, coating inspection where applicable, and review of material test certificates.

Third-party inspection can also be coordinated when required by the buyer or project.

Documentation

Depending on the product, applicable standard and order requirements, documentation may include:

• Mill Test Certificate (MTC)

• Commercial Invoice

• Packing List

• Certificate of Origin where applicable
