Frequently Asked Questions

What sizes of nickel alloy seamless pipe can you supply?
Outside diameter 6–610 mm with wall thickness 0.5–40 mm, up to 12 m in length. Precision and capillary tubes down to 3 mm OD are available on request, as are U-bent heat exchanger tubes.
Do you supply both seamless and welded pipe?
Yes. Seamless pipe and tube are produced to ASTM B167 / B444 / B622 / B163; welded pipe to ASTM B517 / B619 / B704 / B705. We will recommend the right form based on your pressure class and budget.
Do you provide EN 10204 3.1 certificates?
Yes — every lot ships with an EN 10204 Type 3.1 mill test certificate including chemistry, mechanical results and heat number. Type 3.2 certification and third-party inspection (SGS / BV / TÜV) can be arranged before shipment.
What is the MOQ and lead time?
Trial orders of 1–2 tons are acceptable, and stock of common grades (Inconel 625, Monel 400, Hastelloy C-276) can ship within days. Production lead time is typically 15–25 days depending on size and quantity.
What payment and delivery terms do you accept?
T/T with 30% advance and 70% balance before shipment is standard. Delivery terms include FOB Shanghai, CIF and CFR; LCL consolidation is available to reduce logistics cost on smaller orders.
Can you produce custom sizes or special grades?
Yes. Non-standard OD / wall combinations, heavy-wall pipe, small-batch special grades and made-to-drawing tubes are all supported. Send your specification and our engineers will confirm feasibility within one working day.

Standard Dimensions and Wall Thickness (ANSI B36.19 Schedule Table)

Every size below is the nominal dimension published in
ANSI B36.19, reproduced from ASME Section II SB-829 Table 1 — the
general-requirements specification for nickel and nickel-alloy seamless pipe
and tube, through which SB-444 (Inconel 625), SB-407 (Incoloy 800),
SB-622 (Hastelloy C-276), SB-165 (Monel 400), SB-163 and SB-167 all route
their dimensional requirements. The decimal thicknesses are nominal or
average wall dimensions, which is how ASME defines them.

Permissible Variations and Tolerances

Nominal size is not delivered size. The permissible variations for
outside diameter and wall thickness of seamless cold-worked pipe and tube
are set out in ASME SB-829 Table 2 — they are the tolerances a
mill is permitted to work to, and they are what you should hold the supplier
to when the pipe arrives. State them on the purchase order so acceptance is
objective rather than a conversation.

Note A — The permissible variations in this table apply to individual measurements, including out-of-roundness (ovality), except for the following: for pipe and tube having a nominal wall thickness of 3 % or less of the nominal outside diameter, the mean outside diameter shall conform to the permissible variations of this table and individual measurements (including ovality) shall conform to the plus and minus values of the table, with the values increased by 0.5 % of the nominal outside diameter. For pipe and tube over 4-1/2 in. (114 mm) in outside diameter with a nominal wall thickness greater than 3 % of the nominal outside diameter, the mean outside diameter shall conform to the permissible variations of this table and individual measurements shall not exceed twice the permissible variations of the table.
Note B — The permissible variations in this table apply to individual measurements including eccentricity.
