Collection: Socket Weld Reducers (Concentric & Eccentric)
🔹Product Overview
Socket Weld Reducers (Concentric & Eccentric) are high-pressure forged pipe fittings, specially engineered to join piping sections of different nominal diameters in small-bore piping systems. Featuring socket weld end connections, these fittings form rigid, permanent joints with outstanding sealing performance and a compact installation footprint, making them a preferred solution for industrial systems where structural integrity, operational safety and long service life are top priorities.
Concentric Reducers feature a shared centerline between the larger and smaller bore, ideal for vertical pipelines or general diameter transitions where perfect axial alignment is required.
Eccentric Reducers are designed with an offset centerline. They are widely specified in horizontal pipelines to prevent air pocket formation, enable proper liquid drainage, and maintain designed pipeline slope—critical for avoiding flow turbulence, cavitation and system blockages.
All our Socket Weld Reducers are manufactured in strict compliance with ASME B16.11 and can also be produced to meet applicable GOST or customer-specified standards, guaranteeing consistent dimensional accuracy, superior mechanical strength and reliable performance under cyclic pressure and temperature conditions.
