application
- Pipe transition connection: Used for coaxial connection of pipes with different diameters (such as transition from main pipe to smaller branch pipe), ensuring smooth fluid transition.
- Fluid resistance optimization: The conical design significantly reduces turbulence and pressure loss, suitable for critical nodes such as pump inlets and outlets, and before and after flow meters.
- Industrial fields: Oil transportation, chemical processes, water treatment systems, and other scenarios requiring stable flow and high sealing performance.
advantages
- Optimization of fluid dynamics: the central axisymmetric conical structure reduces the generation of vortex and keeps the fluid flow smooth. Generate lower pressure drop than asymmetric reducers, saving system energy.
- Structural reliability:pressure bearing capacity equivalent to seamless steel pipe, impact resistance is high; Zero leakage welding and sealing around joints means no maintenance costs transformations into permanent zero-leakage closing.
- Fitting performance characteristics: Material adaptability: low carbon steel (ASTM A234): Economical, there is an application range in the industry pipeline.
- Stainless steel (304–316L): which has good corrosion resistance, allowing hygienic requirements established for food, drug and other industries.
- Ease of Installation: Common welding joint design in the industry acc.to ISO/ASME B16. 9) .
packing
- Surface Protection Customization:
- Standard Protection: Black paint coating for rust prevention.
- Highly Corrosive Environments: Hot-dip galvanizing or acid washing and passivation treatment (available in silver-white/matte finish).
- Tiered Packaging Strategy:
- Small Diameter (≤4″): Bundled in multiple pieces with foam dividers to prevent collisions.
- Large Diameter (＞4″): Single-piece wooden box packaging with anti-vibration brackets inside for secure fixation.
- Smart Identification System:
- Arrows clearly indicate flow direction (large end → small end).
- Outer box printed with specifications (e.g., DN200 → DN100), material codes, and moisture-proof labels.

Note: The thickness is available with Sch5, Sch10, Sch30, Sch40, Sch80, Sch120, Sch160, STD, XS, XXS, 5S, 10S, 40S, 80S, etc.
- Pipe transition connection: Used for coaxial connection of pipes with different diameters (such as transition from main pipe to smaller branch pipe), ensuring smooth fluid transition.
- Fluid resistance optimization: The conical design significantly reduces turbulence and pressure loss, suitable for critical nodes such as pump inlets and outlets, and before and after flow meters.
- Industrial fields: Oil transportation, chemical processes, water treatment systems, and other scenarios requiring stable flow and high sealing performance.
- Optimization of fluid dynamics: the central axisymmetric conical structure reduces the generation of vortex and keeps the fluid flow smooth. Generate lower pressure drop than asymmetric reducers, saving system energy.
- Structural reliability:pressure bearing capacity equivalent to seamless steel pipe, impact resistance is high; Zero leakage welding and sealing around joints means no maintenance costs transformations into permanent zero-leakage closing.
- Fitting performance characteristics: Material adaptability: low carbon steel (ASTM A234): Economical, there is an application range in the industry pipeline.
- Stainless steel (304–316L): which has good corrosion resistance, allowing hygienic requirements established for food, drug and other industries.
- Ease of Installation: Common welding joint design in the industry acc.to ISO/ASME B16. 9) .
- Surface Protection Customization:
- Standard Protection: Black paint coating for rust prevention.
- Highly Corrosive Environments: Hot-dip galvanizing or acid washing and passivation treatment (available in silver-white/matte finish).
- Tiered Packaging Strategy:
- Small Diameter (≤4″): Bundled in multiple pieces with foam dividers to prevent collisions.
- Large Diameter (＞4″): Single-piece wooden box packaging with anti-vibration brackets inside for secure fixation.
- Smart Identification System:
- Arrows clearly indicate flow direction (large end → small end).
- Outer box printed with specifications (e.g., DN200 → DN100), material codes, and moisture-proof labels.
