Which pipe standards do you support?

We support major international standards such as ASTM A312 / ASME SA312 for stainless steel pipes, plus related project specifications by request.

Do you provide NDT/PMI and MTC?

Yes. Typical options include PMI, hydrostatic test and other NDT scopes depending on the order. MTC (EN 10204 3.1 / 3.2) is available by request.

What size range can you supply?

Typical pipe capacity is OD 10.3 mm to 610.0 mm with WT 1.24 mm to 59.54 mm. Please contact us with your required schedule or project spec.

Q: What information should I include in an RFQ?

Please include grade/material, standard, size (NPS or OD), wall (WT or schedule), length, quantity, end finish (PE/BE), inspection scope (PMI/NDT/Hydro), and destination. We will reply with lead time and inspection scope.

Q: Do you support coating/packing and corrosion service requirements?

Yes. Standard export packing is available (bundle, end caps, wooden box/crate by request). Coating/marking and project corrosion service requirements (e.g., NACE by request) can be reviewed based on the specification.

How do I request inspection scope?

Please specify required tests (PMI, hydrostatic test, NDT) and the applicable standard. We will confirm feasibility and lead time.

Can you supply pipes by schedule and with PE/BE ends?

Yes. Please specify the required schedule (e.g. SCH 10/40/80) and end finish (Plain End / Beveled End). We will confirm availability by grade and size.

What information should I include in an RFQ?
