Stainless Steel Hexagonal Threaded Reducing Pipe Fittings

Cut-out Optimization Technology

Eccentric tapered flow channel design effectively reduces water hammer effect

Smooth arc transition at the cut-out point reduces pressure loss by approximately 40%

Precisely calculated wall thickness gradient ensures balanced overall pressure bearing

Dual Fastening System

Large diameter end: Standard external pipe thread (NPT)

Small diameter end:Metric/Imperial external thread

Center hexagonal structure provides a two-way wrench application point

Product Series: By Cut-out Specifications

Standard Cut-out: 1/2"×3/8", 3/4"×1/2", 1"×3/4"

Large Span Cut-out:** 2"×1", 1-1/2"×3/4"

Technical Parameters

Material: 304/316L Stainless Steel

Pressure Rating: PN16/PN25

Thread Standard: NPT, BSPT, Metric Thread

Hexagonal Specification: 19-46mm across flats (suitable for different pipe diameters)

Typical Applications

Equipment Connection: Connecting large-diameter pipes to smaller equipment interfaces

System Retrofit: Adding smaller diameter branches to existing pipelines

Instrument Installation: Providing reducing connections for flow meters and pressure gauges

Imported Equipment: Adaptable to thread specifications of different national standards

Installation Specifications ① ① Confirm that the thread specifications at both ends match the pipe.

② Wrap PTFE tape around the larger diameter end (15 turns clockwise).

③ Manually screw the larger diameter end into the pipe first.

④ Tighten simultaneously using two wrenches (avoid twisting and deformation).

Quality Commitment: Each piece undergoes go/no-go gauge testing.

2.4 times working pressure test.

Ultrasonic flaw detection at the diameter change.

Material report and pressure test certificate provided.

Selection Guide

Regular water system: 304 stainless steel, standard reducing series.

Chemical media: 316L stainless steel, matching corrosion-resistant gasket.

High pressure conditions: Select integral forged thickened type.

Food and pharmaceutical: Electrolytic polishing of the inner wall, Ra≤0.8μm.
