01 / SCOPE

Select the manufacturing route around service conditions.

The correct pipe is defined by more than outside diameter and wall thickness. Pressure, temperature, corrosion allowance, forming route, heat treatment, testing and end preparation all affect mill selection.

Twelve Mill coordinates seamless and welded supply across process piping, transmission, structural and mechanical applications.

02 / PRODUCT RANGE

A category structured for project procurement.

Seamless carbon and alloy steel pipe
ERW and HFW line and structural pipe
Longitudinal and spiral submerged-arc welded pipe
Stainless and duplex pipe
Hollow sections and mechanical tube
Coated, lined, beveled and cut-to-length products

03 / DOCUMENTATION

Material identity must survive the whole route.

Documentation requirements are established before order placement. Heat numbers, inspection results, dimensional reports, coating records and release notes are reconciled with the packing list and document index.

Third-party inspection and witness points can be coordinated when the project specification requires them.

TECHNICAL QUESTIONS

What buyers ask.

What information is needed for a steel pipe RFQ?+

Provide the governing standard, material grade, outside diameter or nominal size, wall thickness or schedule, quantity, length, end finish, coating, inspection requirements, documentation level and destination.

Can one package include seamless and welded pipe?+

Yes. Mixed manufacturing routes can be coordinated under one commercial and document-control structure, subject to the approved vendor and technical requirements.

Do you supply pipe with EN 10204 certification?+

Certification requirements such as EN 10204 type 3.1 or 3.2 should be stated in the enquiry and confirmed against the selected mill and inspection route.
