Cross

Cross (Four-way) is a multi-directional diversion/combination fitting for industrial pipeline systems, featuring four coaxial or vertically distributed ports. It enables the four-way distribution or convergence of fluids in pipelines, accommodating complex pipeline layouts and serving as a core component for constructing multi-branch fluid systems.Widely used in industries such as petrochemicals, natural gas processing, power stations, and metallurgy, it is installed at complex pipeline junctions to transport fluids like water, oil products, steam, and chemical media. It meets the needs of fluid distribution, mixing, or diversion in multi-process branches, ensuring balanced system flow rates.

Common Types

  • By diameter: equal-diameter cross (all four pipe openings have the same diameter) and unequal-diameter cross (the branch pipes and main pipe have different diameters)
  • By connection method: welded tee, threaded tee, flanged tee
  • By material: carbon steel cross, stainless steel (304/316L) cross, alloy cross

Structural Advantages & Corresponding Benefits

  1. Overall forged equal wall thickness structure

  • Special point: Entirely forged and formed, with uniform wall thickness at the four pipe openings that meets SCH standards, and smooth arc transitions at the pipe intersections.
  • Result:High pressure resistance and impact strength, effectively preventing localized stress concentration and cracking, suitable for high-pressure working conditions, with minimal flow resistance.

  1. Interior wall polishing anti-scaling structure

  • Special point: Electrochemical polishing of the inner wall (Ra≤0.8μm), free from weld beads and burrs, with precisely machined pipe end bevels.
  • Result: Reduces medium residue scaling, lowers conveying resistance, ensures good welding sealing, and prevents medium leakage.
