05

Documentation

List the required MTC certificates and the inspection, packing and marking scope.

Pipe size language

Essential terms that make your enquiry accurate

NPS / DNNominal designations — not always equal to the measured outside diameter.
ScheduleA wall-thickness series — actual wall depends on size and standard.
OD × WTOutside diameter × wall thickness — common for tube and special pipe.
End typeEnds: plain, beveled, threaded, grooved or flanged.
LengthRandom, double-random, fixed or cut length.

Weight & Maritime Freight Calculator

An initial estimate of theoretical weight and 20ft container count, with fields tailored to each metal form.

Formula: diameter² ÷ 162 × length × quantity.
Calculation & Logistic Results
Estimated Total Weight
5.33 Metric Ton (MT)
(5,331 kg)
Estimated container count (20ft FCL)
1 20ft Shipping Container
Assuming a net payload of 27 tons per container

The weight is theoretical and for planning only. Mill tables and carrier and port limits are confirmed in the final quotation.

FAQ

Straight answers before you ask

What project suppliers and industrial buyers ask about most before sending an enquiry.

What is the minimum order quantity?

There is no fixed minimum — quantities are assessed by product, specification and production method. Include your required quantity in the enquiry to receive a comprehensive quote covering packing and shipping options.

Are material test certificates attached to shipments?

Yes — Mill Test Certificates (MTC) to EN 10204 type 2.2 or 3.1 where available, with heat/batch marking and item identification for full traceability from the mill to the port of arrival.

Can inspection be arranged before shipment?

Dimensional, visual and document inspection is coordinated with production, and a third party (SGS, Bureau Veritas or TÜV) can be appointed on request with agreed hold points in the purchase order.

How are products packed for export?

Bundles, pallets, crates, caps and export protection suited to each product type, with mill marking or the agreed project stencil and identification tags — ready for loading into sea freight containers.

Can products be manufactured to custom specifications?

Yes — cutting to size, surface finishes, coatings and end preparation are executed per the approved specification in the purchase order after a technical review of drawings and samples.

Can a grade be substituted with an equivalent one?

Designations from ASTM, EN, JIS and GB systems may differ in properties, testing and dimensional rules. Any proposed substitution goes through our technical review and requires your written acceptance before it is fixed in the order.
