Features of Welded Concentric Reducer


Exhaust reducer pipe Title:

welded concentric reducer SS304 & silicone reducer pipe stainless for motorcycle


Elbow Reducer Hose Infrastructure


The Core function of Stainless Steel Reducers:‌

Multi layer design: Sanitary grade products use inner wall electrolytic polishing to reduce fluid resistance and meet aseptic requirements;


Material:304/304L/316L, special alloys, etc;

Forming process: hot pressing, stamping and welding, etc;


Core Structure of Silicone Reducers:


Straight type: axis concentric variable diameter, suitable for conventional fluid (such as coolant, air) transmission;

Offset: Asymmetric variable diameter design, used for granular media (such as lubricating oil) to prevent sedimentation and blockage;


Process: Integrated molding by compression molding - seamless, uniform wall thickness;

Wrapping vulcanization - low cost, but weak fatigue resistance;

Standards: American Standard (ASME), National Standard (GB/T), Sanitary Grade (DIN/3A), etc;

Application:

Chemical pipeline: 316L material+PTFE lining, resistant to acid and alkali corrosion;

Food and medicine: electrolytic polishing of inner walls;

Marine engineering: Dual phase steel reducer resistant to seawater erosion;

Chemical transmission: Fluorosilicone gel+PTFE lining, resistant to strong solvent penetration;

Automotive industry: turbocharger intake pipeline;


exhaust reducer


Installation steps:

Positioning control: The axial deviation between the reducer and the pipeline is ≤ 1mm, and the low point of the eccentric reducer is aligned with the drainage outlet;


Silicone layer connection: clamp installation

The clamp should be aligned with the position of the stainless steel reinforcement ring, and it is forbidden to compress the pure silicone area;

Symmetrical tightening of bolts;
