Product Description

Streamline your complex piping grids with Puhui’s PE100 cross tees (4-way crosses). Designed to connect four pipes at a single intersection, these fittings reduce potential leak points by 50% compared to using two standard tees. Rated for PN16 pressure and compliant with EN12201, ISO 4427, AS/NZS 4129, our injection-molded HDPE crosses ensure uniform flow distribution, superior chemical resistance, and a 50-year service life in municipal, industrial, and irrigation infrastructures.

Applications

✅️Municipal Grid Infrastructure: Centralized water distribution and manifold systems.

✅️Large-Scale Irrigation: Distributing water to multiple zones from a central mainline.

✅️Fire Protection Systems: Ensuring even water pressure across four branching sprinkler lines.

✅️Industrial Process Plants: Multi-directional chemical transport and cooling water loops.

Advantages

50% Fewer Leak Points: A single cross requires only 4 fusion joints, whereas two tees and a connecting nipple require 8 joints.[1] Fewer joints mean a significantly lower risk of installation errors and long-term leaks.
Optimized Flow Dynamics: The symmetrical internal geometry of a molded cross reduces turbulence and pressure drop compared to the staggered, turbulent path created by two consecutive tees.
Space Efficiency: Ideal for cramped mechanical rooms, pump stations, and underground manifolds where every inch of space is critical.
Simplified Installation: Reduces labor time and material handling, allowing for faster project completion.

Q&A

Q1: What is the main advantage of an HDPE cross fitting?
A: The primary advantage is system reliability. A cross fitting replaces two tees and a pipe nipple, reducing the number of fusion joints by half. This minimizes potential leak points and installation time while saving space.

Q2: Does a cross tee cause more pressure drop than a tee?
A: Actually, a single molded cross often provides better flow characteristics than two staggered tees. The internal design is optimized for multi-directional flow, which minimizes the turbulence typically found in a “two-tee” configuration.

Q3: Is the Puhui PE cross UV resistant for outdoor use?
A: Yes. Our black PE100 fittings are compounded with high-quality carbon black, providing excellent UV stability. They will not structurally degrade even after decades of exposure to direct sunlight.

Q4: Can I use this cross for gas distribution?
A: Puhui offers specific PE fittings certified for natural gas (SDR11/PN10 for gas). Please specify your application during the inquiry to ensure you receive the correctly rated and certified component.

Q5: What sizes are available for PE cross fittings?
A: We provide injection-molded crosses in standard metric sizes ranging from DN63 to DN800. For diameters above 800mm, we offer fabricated segments to meet custom project requirements.
