Titanium Reducer —  Export Supply from Baoji Titanium Valley

A titanium reducer changes pipe bore while keeping the line corrosion-resistant. We stock concentric and eccentric reducers in Gr2 and Gr7, ASTM B363, butt-weld. Grade 2 for neutral chloride; Grade 7 for reducing or acidic media.

1. What Titanium Reducer Is and Where It Is Used

Titanium Reducer is specified wherever stainless steel fails by corrosion but the part must stay light, strong, or biocompatible. Typical uses:

• Pump-suction transitions (desalination fittings)
• Gr2 fittings chemical line bore changes
• heat-exchanger fittings exchanger nozzle transitions
• Eccentric reducers to avoid air pockets on suction
• Offshore topside piping

2. Grade Selection

: Which Titanium to Specify

Grade 2 reducers — part of Gr2 fittings — suit seawater and neutral chloride. Grade 7 — Gr7 corrosive fittings — is for corrosive, reducing media. Both are butt-weld per tee/elbow/reducer stock for leak-tight joints.

3. Standards and Dimensions to State on the RFQ

State the governing standard, dimensions, and tolerance up front so quotes are comparable. For Titanium Reducer this is usually the relevant ASTM/ASME grade plus your drawing or nominal size. Insist on mill-test certification with heat-number traceability.

4. Titanium Reducer in Seawater and Chloride Service

For open, aerated seawater Grade 2 is the default; where the service is reducing, acidic, or has stagnant/creviced zones, step up to Grade 7 (Ti-0.15Pd). Keep flow velocity in the 1–2 m/s band to prevent deposit-driven crevice attack. Related reading: seawater desalination plate and Grade 7 seawater exchanger.

5. The Limitation You Must Know

: Where Titanium Reducer Fails

A reducer’s narrow bore raises local velocity and can trap solids — design for the 1–2 m/s band and prefer Gr7 in low-oxygen crevices. Material exclusions are unchanged: no dry halogen, no concentrated nitric, no fluoride. Avoid galvanic coupling to steel without insulation.

6. Sizing and Specification Checklist (RFQ-Ready)

1. Grade and temper (Gr2 / Gr5 / Gr7 / Gr12 / Gr23) with the reason above.
2. Dimensions — size, thickness/OD, length, or bore as applicable.
3. Standard (ASTM/ASME/EN) and tolerance class.
4. Quantity and lot — single piece or batch.
5. Surface finish — pickled, polished, machined, or as-rolled.
6. Certificate — EN 10204 3.1 with heat number.
7. NDT requirement — RT/PT/ET where the code demands it.
8. Packing and destination — export packing and freight.
9. Concentric vs eccentric, and offset side
10. Large/small bore and wall schedule

7. Common Procurement Mistakes

• Using concentric where eccentric is needed to vent suction (air pocket)
• Gr2 in reducing/acidic line (use Gr7)
• Galvanic coupling to steel pipe without insulation

8. Concentric vs Eccentric Reducer

A tee/elbow/reducer stock concentric reducer keeps the centreline; an eccentric reducer offsets it to keep the pipe flat or vent air on pump suction. Both are butt-weld and available from stock or butt-weld fittings to spec to spec.

9. Why Buy From a Baoji Titanium-Valley Stockist

We hold ~800 tons of titanium and nickel inventory in Baoji, China’s Titanium Valley, and cut to size the same day. That means small MOQ, fast dispatch, and the ability to supply both standard stock and non-standard parts to drawing — without a minimum-lot penalty. Every lot ships with MTC and export documentation.

11. FAQ — Titanium Reducer

What reducer types do you supply?

Concentric and eccentric, Gr2/Gr7, ASTM B363 butt-weld, stock and custom.

When use eccentric reducer?

On pump suction to keep the top/bottom flat and avoid air pockets.

Which grade for seawater?

Grade 2 for open seawater; Grade 7 for reducing or stagnant service.

Are they butt-weld?

Yes — per ASTM B363 / B16.9 for full-strength joints.

Can you make non-standard sizes?

Yes — fabricated to spec, including small batches.

What certification?

EN 10204 3.1 MTC; NDT where specified.

Do you export?

Yes — worldwide from Baoji.

Summary: Choose by Service, Not by Habit

Choose Gr2 reducer if seawater or neutral chloride. Choose Gr7 if reducing/acidic media. Choose eccentric if pump suction needs venting; concentric otherwise.
