उत्पाद विवरण

Stainless Steel 304/316L Butt Welding Concentric Reducer ASME B16.9 Class 150
 
1. Product Description

 

Stainless steel reducers are strictly classified into two types based on centerline alignment. Incorrect selection directly impacts system safety:

  • Concentric Reducer (CR): Both ends share the same centerline with symmetrical diameter reduction. Suitable for vertical risers, pump discharge vertical sections, or gas transmission lines, where fluid transitions evenly along the center. Not recommended for horizontal liquid lines due to potential bottom pooling.

  • Eccentric Reducer (ER): Centerlines are parallel but offset, with one straight side (flat-bottom or flat-top installation). For horizontal liquid pipelines, flat-bottom installation (straight side down) is mandatory to prevent liquid accumulation and crevice corrosion. For horizontal gas pipelines, flat-top installation (straight side up) is required to prevent condensate pooling. This is the most critical engineering principle in reducer selection.


2. Product Applications

 

Industry Typical Media Recommended Material
Petrochemical Crude oil, refined products, sour gas 316L / Duplex 2205
Marine/Ocean Seawater, salt spray 904L / Super Duplex 2507
Food & Pharmaceutical Purified water, steam, CIP solutions 304L / 316L (mirror-polished)
Power Generation High-temp steam, feedwater 321H / 347H (stabilized grades)
Semiconductor High-purity gases, UPW 316L EP-grade (electropolished)

​3.Product Advantages

  • Solution Annealing: All forged/stamped products undergo solution annealing (1040～1120℃) followed by rapid water quenching, ensuring intergranular corrosion resistance and eliminating cold-work stresses.

  • Full-Loop Inspection Chain: Raw material verification → dimensional check → forming temperature monitoring → ultrasonic wall-thickness verification → bevel angle inspection → surface roughness sampling → hydrostatic/pneumatic testing.

  • NDT Coverage: 100% dye penetrant (PT) or magnetic particle (MT) inspection on weld ends; radiographic testing (RT) available upon request for pressure-retaining walls.

  • Full Traceability: Each fitting is stamped with heat number, size, and standard. Material test certificates are provided with each shipment, ensuring full lifecycle traceability.
