Cross
Equal & Reducing Pipe Cross | 4-Way Distribution | Seamless & Welded Industrial Fittings
Pipe cross is a four-way pipe fitting designed for pipeline branching and medium distribution, available in equal and reducing types. We manufacture carbon steel cross for general industrial piping and stainless steel cross for corrosive medium applications. Seamless and butt weld cross comply with ASME B16.9 standards, suitable for multi-branch piping systems.
As a professional pipe cross manufacturer, we support custom sizes, wall thicknesses and connection types including socket weld and threaded ends.

Main Classification
- By structure: Equal Cross (same bore on all ends), Reducing Cross (mixed diameter ports)
- By craft: Seamless cross, welded cross
- By connection: Butt weld cross, socket weld cross, threaded cross
Application Limits
Equal cross is preferred for uniform branch piping; reducing cross fits mixed-diameter multi-branch systems. Not recommended for high-pressure main trunk lines; mainly applied to auxiliary and branch pipe networks.
Comparison Table：Equal Cross VS Reducing Cross
| Item | صليب متساوٍ | Reducing Cross |
| Bore size | All four ends with identical diameter | Custom mixed bores for different pipe sizes |
| Flow state | Balanced flow on all branches | Flow rate varies with bore difference |
| Pressure capacity | Stable performance at full pressure range | Slightly lower capacity at reduced end |
| Typical usage | Standard uniform branch piping | Multi-diameter integrated pipe networks |
| Cost | Standard size, lower cost | Custom size, relatively higher cost |
Comparison Table：Butt Weld / Socket Weld / Threaded Cross
| Item | لحام تقاطع اللحام التناكبي | صليب اللحام المقبس المتقاطع | Threaded Cross |
| Connection | Full penetration butt weld | Socket insert + fillet weld | Screw thread assembly |
| Suitable size | DN50–DN2000 medium & large bore | DN15–DN100 small bore | DN15–DN80 small bore |
| Pressure rating | High pressure & temperature | Medium pressure | Low pressure only |
| Installation | Requires on-site welding | Simple socket welding | No welding, quick assembly |
| Typical scenario | Main branch process piping | Instrument & utility piping | Low-pressure water & gas lines |
