Reducer
What is a Socket Weld Reducer?
A Socket Weld Reducer is a forged pipe fitting used to connect two pipes of different diameters in high-pressure systems, ensuring a secure, leak-proof transition. It features socket ends on both sides where the pipes are inserted and welded externally. This design provides excellent structural integrity, making it ideal for applications involving pressure, vibration, or thermal expansion.
Socket weld reducers are commonly found in oil & gas refineries, steam lines, power generation systems, and chemical plants, and are available in concentric and eccentric designs based on flow alignment requirements.
Key Features
- Smooth Diameter Transition – Maintains efficient fluid dynamics and pressure balance.
- Compact and Durable – Suitable for space-constrained, high-stress systems.
- Leak-Resistant Weld – Secure socket weld joint prevents leakage.
- Material Versatility – Carbon steel, stainless steel, and alloy options.
- Standard Compliant – Follows ASME B16.11 and MSS-SP specifications.

Do you have questions?
What is the purpose of a socket weld reducer?
It allows connection between two pipes of different diameters while maintaining pressure and flow efficiency.
Are both concentric and eccentric types available?
Yes, we offer both types, although concentric is standard in socket weld configurations.
Can reducers be used in vertical pipelines?
Yes, especially concentric reducers for maintaining centerline flow. Use eccentric if drainage is required.
Do reducers come with certification and testing?
Yes. We provide Mill Test Certificates (MTCs) and optional TPI reports upon request.
