Product Description

Product Description

• Size Range

  Fitting Type	Size Range (Inches)	Equivalent (DN)
  Seamless Reducers	1/2" to 24"	DN15 to DN600
  Welded Reducers	8" to 48"	DN200 to DN1200

• Pressure Ratings
  Aligned with ASME B31.1 (Power Piping) and B31.3 (Process Piping), covering ratings such as Sch 10, Sch 40, Sch 80, and Sch 160, suitable for high-pressure applications up to 2500 psi.
• Dimensional Tolerances
  • Diameter: ±1% for sizes ≤ 12", ±0.75% for sizes >12"
  • Wall thickness: ±12.5% (as per ASTM A403)
  • Length: ±1/8" for sizes ≤ 24", ±1/4" for sizes >24"

 

Common Grades (ASTM A403)

Grade	Chemical Composition Highlights	Key Properties
WP304/304L	18% Cr, 8% Ni (304L: ≤0.03% C)	Good general corrosion resistance, ductility.
WP316/316L	16% Cr, 10% Ni, 2% Mo (316L: ≤0.03% C)	Superior resistance to chlorides and acids.
WP310S	25% Cr, 20% Ni	High-temperature resistance (up to 1150°C).
WP347	18% Cr, 10% Ni, stabilized with Nb/Ta	Resists intergranular corrosion at high temps.

 

• Material Advantages
  • Corrosion Resistance: Chromium forms a passive oxide layer, protecting against rust, acids, and alkaline media.
  • High Strength: Maintains mechanical integrity under pressures up to 2500 psi and temperatures from -20°C to 650°C.
  • Weldability: Suitable for GTAW, GMAW, and SMAW welding methods, with post-weld heat treatment (PWHT) optional for stress relief.
