Steel pipe sourcing from China — seamless & welded, to API and EN
Seamless and ERW welded pipe — line, structural and fluid — in API 5L, ASTM A53, S235 and Q235, with mill test certificates and hydrotest verification.
Steel pipe spans a wide range — line pipe for fluids, structural hollow sections, and general fluid and conveyance pipe — in both seamless and welded (ERW) construction. We source pipe from verified Chinese mills to the standard your application requires, in carbon and low-alloy grades.
Pipe is judged on wall thickness, weld integrity and pressure rating, and that is where corners get cut: under-thickness walls, ungauged welds, or a missing hydrotest. We verify the mill test certificate, check outside diameter and wall thickness, and confirm hydrostatic and NDT testing where the standard calls for it before shipment.

Frequently asked questions
Seamless or welded — which do you supply?
Both. Seamless for higher-pressure and critical service, ERW welded for general fluid and structural use; we source to the standard you specify and inspect accordingly.
Do you confirm hydrotest and wall thickness?
Yes — we gauge OD and wall thickness against tolerance and confirm hydrostatic and NDT testing per the applicable standard before shipment.
Can pipe be supplied galvanized?
Yes — bare, black or hot-dip galvanized, with the coating and ends (plain or bevelled) confirmed on inspection.
The risks of sourcing from China — and how we remove them
Every importer faces the same handful of failure points. Here's what each one is, and what we do about it.
01Paying a trader's hidden markup
We verify the supplier is the actual manufacturer and show the factory price separately from our fee, so you never overpay a middleman.
02A 'factory' that turns out to be a shell company
We check business licenses, capacity and history, and visit the site in person before you commit a single payment.
03Losing the deposit to fraud
Funds go to Silk Way Sourcing under one contract, not to an unknown account, and the balance is tied to an inspection you approve.
04Receiving goods that don't match the sample
An independent pre-shipment inspection checks quantity, dimensions and quality against your spec, with a photo report, before anything ships.
05Goods stuck at customs over paperwork
We prepare and handle export and customs documentation end to end, so shipments clear without costly holds.
What importers say after working with us
Sourcing wins across steel, solar, energy storage, construction materials and supplier verification. Client names are withheld for confidentiality.
- Steel & metals
We needed 200 tonnes of hot-rolled coil and kept getting quotes from traders. Silk Way took us straight to the mill, verified it, and inspected the load before we paid the balance.
