Chinese ERW steel pipe manufacturers and suppliers covered in this guide areForever Steel, Youfa, Baosteel, Hebei Huayang, Tianjin Shuangjie, Hengshui Jinghua, Tianjin United Steel Pipe, Baoji Petroleum Steel Pipe, Yuantai Derun and Weifang East Steel Pipe. Their ranges cover line pipe, galvanized pipe, structural tube, mechanical tube and project supply.

How were these ERW pipe manufacturers selected?

The shortlist was checked for published ERW or high-frequency welded products, identifiable company information and relevance to pipe procurement. Company profiles support the descriptions below; they do not establish current certification, available stock or qualification for a particular project.

For an actual order, compare six items: product scope, producing mill, inspection plan, coating and ends, release documents, and delivery terms. Equivalent quotations require the same specification and an explicit list of deviations.

Specification update:API published the47th edition of API Specification 5L in June 2026, with changes covering HFW quality, inspection, testing and traceability. State the contractually applicable edition in the RFQ; publication of a new edition does not automatically change an existing purchase order. API announcement.

China ERW steel pipe manufacturers comparison

History dates marked as heritage or predecessor dates are not presented as the incorporation dates of the current legal entities. Company locations are not necessarily the factories assigned to an order. Request the producing mill's name and address with the quotation. Sources for each entry appear in the profiles below.

Official website.

Which manufacturers match your pipe application?

Use the following table to choose which companies receive an RFQ. The groupings reflect the published ranges above; they are not exclusive recommendations or proof of project approval.

What should buyers verify before ordering ERW pipe?

Product standard and manufacturing route

An ERW pipe order needs a complete product designation: standard and edition, manufacturing type, grade, dimensions and any additional service requirements. ASTM A53/A53M explicitly identifiesType E as electric-resistance-welded; specifying only “ASTM A53 pipe” leaves the manufacturing type undefined. ASTM specification scope.

For API 5L line pipe, state the grade, product specification level, route and contract edition. Add project requirements for sour service, low temperature or other special conditions. Ask the mill to return a compliance statement and list each deviation.

Producing mill and certification scope

The seller should name the actual factory, any subcontracted processing and the issuer of the MTC. Pipe markings, heat or batch identification and release documents must refer to the delivered material.

Where API Monogram licensing is required, check the named facility and relevant scope in the API Composite List. An API 5L reference in a brochure and a current Monogram license are separate matters.

Weld inspection and hydrostatic testing

Agree on the inspection and test plan before production approval. Specify the examinations, tests, acceptance basis, witness points and records required by the governing standard and order. Clarify weld-seam inspection coverage, pipe-end examination, treatment of repaired areas where applicable, and hydrostatic testing.

A hydrostatic test does not replace weld examination or other specified acceptance tests. The technical offer should identify how each requirement will be met, including any additional mechanical testing.

Weld bead and pipe ends

Specify the internal weld-bead condition where flow, internal coating, component fit or subsequent fabrication makes it relevant. State any removal and measurement requirements; accessibility and finishing capability vary with pipe dimensions.

Define plain, beveled, threaded, coupled or grooved ends. For mechanical couplings, identify the connection system and required end geometry rather than requesting a generic groove.

Coating, documents and delivery scope

Specify the coating system, surface preparation, thickness basis, cutbacks, inspection and repair procedure. Name the coating facility and the party responsible for the final records. Temporary transport protection should not be confused with a service coating.

Compare packing, marking, MTCs, test reports, delivery terms and quantity or weight settlement on the same basis. Resolve exclusions before comparing prices.

What should an ERW steel pipe RFQ include?

An ERW pipe RFQ should define the application, product specification, dimensions, inspection, finish, documents and delivery terms. Send every bidder the same schedule and attachments, then compare written deviations before accepting a commercial offer.

For a quotation from Forever Steel, send this schedule with the required ERW pipe specification and associated coating, processing or fitting items. Request the mill, inspection responsibilities and delivery scope in the written offer.

Frequently asked questions

Which ERW steel pipe manufacturer in China is best?

The best manufacturer is the one that meets the ordered specification, inspection and delivery requirements. Compare current technical offers for the same product. Corporate size or a catalog's oil-and-gas label does not establish suitability for a particular line-pipe order.

What is the difference between ERW and HFW pipe?

ERW means electric resistance welded pipe. HFW identifies high-frequency welding, commonly used in modern welded-pipe manufacture. Specify the actual process and product requirements: the ERW label alone does not establish welding frequency, heat treatment or mill qualification.

Can ERW pipe be used for oil and gas pipelines?

Yes, when the design and procurement specification permit the route and the pipe meets the ordered requirements. Confirm the standard, grade, specification level, dimensions, inspection and any special-service qualifications with the producing mill.

Does an API 5L reference prove that a manufacturer is API licensed?

No. A product-specification reference and an API Monogram license are different. Where licensing is required, verify the named facility, status and relevant scope in API's current directory and match them to the order.

Should I buy from a mill or a project supplier?

A mill can quote a defined production order; a project supplier can coordinate multiple products and processing stages. Both should identify the producing factory, inspection responsibilities, traceability and claim-handling arrangements in writing. Choose according to the required scope.

What should I check before accepting the lowest quotation?

Check standard, grade, manufacturing route, dimensions, testing, ends, coating, documents, packing and delivery terms. Resolve deviations and exclusions first. A price for reduced inspection, different tolerances or incomplete finishing is not an equivalent quotation.
