Small Size Titanium Flange Ready Stock | NPS 1/2–2" Gr2/Gr5/Gr7, ASME B16.5, Forged + CNC, MTC 3.1

Meta Description: Small bore Titanium Flanges NPS 1/2–2" (DN15–DN50) machined from confirmed heats — ASTM B381 F-2 (Gr2/R50400/3.7035), ASME B16.5 WN/SO/Blind/SW/Threaded, RF/FF/RTJ, UT+PT, EN 10204 3.1. Lot-confirmed dispatch, 24h quote, FOB Shanghai.

What "Small Size" Means Here

NPS 1/2, 3/4, 1, 1-1/4, 1-1/2, 2 (DN15–DN50)
Class 150 / 300 rotating; 600 on PO
Types: WN / SO / Blind / Socket Weld / Threaded / LJ
Sch 5S–80S bore matched to mating pipe
Face: RF (default), FF, RTJ on request

Stock Logic (honest version)

We do not claim "10,000 pcs of every combo on shelf" — that is not how titanium works. Real fast dispatch =

Confirmed annealed Gr2 forging blanks / rough rings on rotating heats
In-house CNC slot reserved for small-bore turn jobs
MTC 3.1 draft pre-linked to parent heat
Quote in 24h; dispatch window quoted after lot confirm (not "same-day on all faces")

Result: small-bore Gr2 WN/Blind/SO reaches CNC slot quickly — faster than re-melt or trader relay, without faking "universal stock".

Typical Small-Bore Stock Combo

NPS	DN	Class 150 BCD (mm)	Class 300 BCD (mm)	Bolts
1/2"	15	60.5	66.7	4
3/4"	20	69.9	82.6	4
1"	25	79.2	88.9	4
1-1/2"	40	98.6	114.3	4
2"	50	120.7	127.0	4 (Cl150) / 8 (Cl300)

Dimensions per ASME B16.5 current edition; PCD/bore confirmed before drill. [3,6](@ref)

Grade Identity (write all on tag)

Gr2 = ASTM B381 F-2 = WPT2 = UNS R50400 = W.-Nr. 3.7035
Gr5 (TC4) = F-5 / R56400; Gr7 = F-7 (Pd); Gr12 = F-12
Chemistry confirms grade — not the sticker

QC Before Dispatch (small bore too, no shortcut)

Heat No. etched pre/post machine (parent = finished)
UT on forging, PT on machined face
PMI/XRF grade verify
Bore + PCD + RF height to B16.5
EN 10204 3.1: measured O/H/N/C/Fe + tensile, QA-signed
Face foam + bevel cap + VCI paper in ISPM-15 case

Where Small-Bore Ti Flanges Go

Instrument take-offs, sample lines, analyzer taps
Heat-exchanger tube-sheet nozzles
Desalination branch lines, seawater MRO spares
Lab/pilot rigs, pharma ultrapure tie-ins
Offshore skid weight-saving replacements for 316L

FAQ — Small Size Titanium Flange Ready Stock

Q1: Truly in stock?
A: Confirmed-heat blanks rotate; CNC slot scheduled after lot confirm. Window quoted in writing — no "everything same-day" claim.

Q2: Min order?
A: 1 pc for MRO/qualification. Small-batch friendly.

Q3: Threaded titanium flange OK?
A: Yes for small-bore low-pressure non-welded tie-ins; NPT/BSPT on request. Not for cyclic high-pressure duty.

Q4: Class 150 vs 300 same PCD?
A: No — 2" Class300 jumps to 8 bolts / 127mm PCD. Confirm class before drill.

Q5: Gr2 enough for seawater small bore?
A: Yes for ambient–moderate T. Hot crevice brine → Gr7/Gr12 review.

Q6: RTJ on 1/2"?
A: Machinable, but ring groove + metal gasket; confirm design pressure first.

Q7: MTC 3.1 on small qty?
A: Always. Heat chemistry + tensile, QA-signed. Speed never downgrades cert.

Q8: Air freight for urgent MRO?
A: DAP airport on request; small carton, fast customs with CI/PL/MTC/COO.

Q9: 3.2 possible?
A: TPI named at PO; cannot be back-built from 3.1 after shipment.

Q10: HS code?
A: WCO 6-digit 8108.90 base; destination sub-heading via broker.
