Forged Pipe & Tube Solutions – Large Diameter & Thick-Wall

Forged pipes serve high-pressure and critical service with dense grain structure, uniform wall thickness, and superior fatigue strength—ideal for long-life, leak-proof systems. Typical configurations include large-diameter and thick-wall forged hollows, with pressure classes from 2000 to 6000 lb for demanding service.

Available in forged hollows or bored-from-solid routes, these pipes enable tight ID/OD and concentricity control with optional UT/RT and heat treatment (T6/T651/T7451).

• Features: Large-diameter, thick-wall, seamless forged construction; extended fatigue life
• Manufacturing Routes: Near-net forged hollows; bored-from-solid with deep-hole drilling
• Quality Options: Heat treatment (T6/T651/T7451), NDT (UT/RT), EN 10204 3.1 on request

Note: Forged tubes are also available for aerospace/precision structures when lightweight stiffness, tight ID/OD tolerance, or non-round geometry is required.

Knowledge Center & FAQs — Forged Aluminum Pipe, Tube & Fittings

Open-Die vs Closed-Die vs Rolled Ring Forging

Open-die forging is flexible for large and simple shapes, closed-die forging ensures precision for complex geometries, while rolled ring forging delivers optimized grain flow for hollow rings and pressure components.

Forged vs Wrought Fittings

Wrought fittings are shaped by rolling or extrusion, but forged fittings are compressed under high pressure, achieving denser grain structure and superior pressure resistance.

Aluminum vs Steel vs Titanium

Aluminum forged fittings provide lightweight and corrosion resistance, steel offers maximum load capacity, and titanium achieves extreme strength-to-weight ratios at higher cost.

Forged Pipe vs Extruded/Seamless Pipe

Forged aluminum pipe/tube is produced by forging (near-net hollow or bored-from-solid), giving denser grain flow and better fatigue/pressure resistance. Extruded or drawn products are suited for standard OD/wall but less optimal for large-diameter or ultra-thick applications.

Can aluminum forged fittings comply with ASME B16.11?

Yes. ASME B16.11 specifies dimensions and pressure classes for socket-weld and threaded forged fittings. Chalco supplies forged aluminum fittings manufactured in compliance with these requirements.

What pressure classes are available for forged fittings?

Class 2000 / 3000 / 6000 are available for socket-weld and threaded forged fittings per ASME B16.11.

What sizes can Chalco manufacture for forged pipes and tubes?

Capability covers OD 20–800 mm, wall ≥5 mm, and length up to 1500 mm. Deep-hole boring and CNC machining ensure tight concentricity and tolerance.

Which alloys are available?

Aluminum grades include 6061, 7075, 5083, 2024, 7050, 2219. Custom alloys available on request.

What quality documentation and inspections can be provided?

EN 10204 3.1 certificates, dimensional and heat-treatment reports, plus optional NDT (UT/RT). Mechanical testing can be arranged per specification.

What is the difference between "pipe” and "tube”?

"Pipe” usually refers to pressure-service, large-diameter and thick-wall sections; "tube” emphasizes precision geometry and lighter structures in aerospace and machinery. See more in The difference between pipe and tube.

Can you supply heat-treated and finish-machined parts?

Yes. Heat treatments such as T6/T651/T7451 are available by alloy/spec. CNC finish machining (including deep-hole drilling/boring) is supported to drawing tolerances.

How should I send an RFQ to speed up quotation?
