Product Detail
Product Introduction
Titanium elbows are a direction-change fitting family selected by bend angle, centerline radius, pipe size, wall and end preparation. A 45-degree or 90-degree designation controls direction change, while long-radius or short-radius controls centerline radius; both dimensions may be needed in one complete fitting description. Use this family page to select the required configuration before quotation.
How should a titanium elbow be selected?
Selection answer: Choose the elbow by flow-direction change, long-radius or short-radius geometry, connected-pipe dimensions, wall or schedule, grade and piping design. Common angles include 45 and 90 degrees, while other angles require an approved drawing.
Selection boundary: An elbow with the correct nominal size can still be unsuitable if radius, center-to-end dimensions, wall thinning, forming route, bevel, grade or inspection do not match the system.
RFQ data to confirm: Provide grade, product and dimensional standards, angle, long or short radius, NPS or OD, wall or schedule, seamless or welded route, bevel, service conditions, quantity, NDE and certificates.

Selection and Configuration
- Direction angle: Choose 45-degree, 90-degree, 180-degree return or drawing-specific angle from the piping route.
- Centerline radius: Define long radius, short radius or a drawing radius independently from the angle.
- Complete geometry: State NPS or OD, wall/schedule, center-to-end dimensions, tangent lengths, weld bevels and construction route.

Services We Can Provide
Product Packaging
Fittings are capped or wrapped to protect clean ends, bevels, threads and machined faces. Items are separated by grade, size and heat/lot, then packed in reinforced cartons or export cases according to geometry and quantity. Typical export packaging for the same physical product form is shown below; final packing is confirmed for each order.
Application Scenarios
Chemical Processing
Corrosion-resistant piping for acids, chlorides and process media after grade compatibility review.
Power & Energy
Cooling-water, condenser and auxiliary piping requiring traceable titanium components.
Marine & Desalination
Seawater and chloride-bearing piping systems designed for the selected titanium grade.
FAQ
Is a 90-degree elbow always long radius?
No. Angle and radius are separate. A 90-degree elbow may be long radius, short radius or drawing-specific.
What information is needed besides NPS?
Provide angle, centerline radius, wall or schedule, center-to-end dimensions, grade, ends, construction route and inspection.
When is a pipe bend different from an elbow?
An elbow commonly follows a standard fitting geometry; a pipe bend may use a larger or drawing-specific radius and tangent lengths.
