Types of Pipe Fittings – A Simple Guide for Engineers & Buyers (2025 Updated)

Elbows change the direction of flow in a pipeline. Most common angles: 45°, 90°, 180°.

• Chemical plants
• Water lines
• HVAC
• Steam systems

• Short radius (for tight spaces)
• Long radius (for smooth flow)

Tees are used to divide or combine flow.

All 3 sides are the same size.

One branch is smaller, useful for controlled flow.

• Branch lines
• Distribution pipelines
• Chemical injection points

Reducers help transition between different pipe sizes.

Cone-shaped, used where the pipe is centered.

One side flat — perfect for pumps because it prevents air pockets.

• Pump suction
• Energy systems
• Fluid control lines

Permanently joins two pipes.

Used when frequent disassembly is needed.

• Plumbing
• Firefighting
• Instrumentation
• Utility pipelines

Caps and plugs close the end of a pipe system.

• Testing
• Maintenance
• Isolation
• Dead-end lines

Bends provide smoother direction change compared to elbows.

• Lower pressure drop
• Better flow
• Less turbulence

• Refineries
• Petrochemicals
• Large radius piping

Choosing the wrong fitting can cause serious issues:

• Flow restriction
• Pressure loss
• Pump damage
• Leakage or failure
• Costly downtime

Correct fittings ensure:

• Smooth flow
• Long system life
• Safety & compliance
• Proper pressure balance

• Stainless Steel (304, 316, 321) – For water, food, pharma, chemicals
• Alloy Steel (A234 WP22, WP5) – High temperature and high pressure
• Carbon Steel (A234 WPB) – General and low-pressure applications
• Nickel Alloys (Inconel, Monel, Hastelloy) – Extreme corrosion environments

• 15+ years of experience
• Full range: elbows, tees, reducers, bends, caps, couplings, unions
• Stainless, Alloy Steel, Carbon Steel, Duplex, Super Duplex
• Testing: PMI, UT, Hydro Test, DP Test
• MTC 3.1 / 3.2 provided
• Exports to 45+ countries
• Custom fittings available

Pipe fittings may look simple, but choosing the right type is crucial for flow control, pressure management, and system reliability.
