Pipe Fittings

Industry Definition & Scope
The pipe fittings industry involves the manufacturing, distribution, and application of components used to connect, terminate, control, branch, or change the direction of piping systems. Fittings are essential for constructing leak-proof, efficient, and adaptable fluid transport networks in industrial and commercial infrastructure.

Key Product Categories

1. By Connection Method:

   • Threaded Fittings: NPT, BSPT threads for low-pressure systems.

   • Socket Weld Fittings: High-strength joints for critical pipelines.

   • Butt Weld Fittings: Seamless integration in high-pressure/temperature systems.

   • Flanged Fittings: Bolted connections for maintenance flexibility.

   • Press/Quick-connect Fittings: Installation efficiency in HVAC and plumbing.

2. By Function:

   • Elbows (45°/90°): Change flow direction.

   • Tees & Crosses: Create branches.

   • Reducers & Expanders: Adjust pipe diameter.

   • Caps & Plugs: Seal pipe ends.

   • Couplings & Unions: Connect/disconnect pipe sections.

   • Adapters & Bushings: Transition between materials/threads.

3. By Material:

   • Metallic: Carbon steel, stainless steel, alloy steel, copper, brass.

   • Non-Metallic: PVC, CPVC, HDPE, PP, PVDF for corrosion resistance.

   • Composites: FRP, lined fittings for specialized applications.

4. By Application:

   • Oil & Gas: Pipeline fittings, wellhead components.

   • Chemical Processing: Corrosion-resistant alloy fittings.

   • Power Generation: High-temperature/pressure fittings.
