Positive Cross Tube

Product Overview​

Sikerui PPH Positive Cross Tube is a high-performance pipe fitting engineered from unplasticized polyvinyl chloride (PPH), designed to create seamless four-way connections in complex piping networks. This specialized cross fitting enables efficient flow distribution across multiple directions while maintaining consistent pipe diameters, ensuring optimal performance in industrial, plumbing, and irrigation systems. Renowned for its exceptional durability, corrosion resistance, and cost-effectiveness, it complies with international standards such as DIN and ISO 4422. With a service life exceeding 50 years, the UPVC Positive Cross Tube combines lightweight simplicity with robust performance, making it a sustainable alternative to metal fittings. Its smooth interior surface minimizes flow resistance, while resistance to chemicals, UV radiation, and abrasion guarantees reliability in diverse applications.

Features of PPH Positive Cross Tube​

1. Four-Way Flow Distribution​
   • Engineered with four uniform outlets to facilitate efficient multidirectional flow splitting or convergence, reducing turbulence and maintaining pressure balance in complex pipeline networks.
2. Superior Corrosion & Chemical Resistance​
   • Highly resistant to acids, alkalis, and corrosive fluids, ideal for industrial wastewater, chemical transport, and agricultural systems involving fertilizers or pesticides.
3. Smooth Interior Surface​
   • Precision-molded inner walls minimize friction loss, prevent sediment buildup, and ensure optimal flow efficiency for water, sewage, or chemical fluids.
4. Lightweight and Easy Installation​
   • Up to 50% lighter than metal equivalents, enabling quick solvent cement or threaded connections. Reduces labor time and transportation costs significantly.
5. Durable Under Pressure​
   • Rated for pressures up to PN16 (1.6 MPa) and temperatures from 0°C to 60°C. Robust SCH80 variants withstand higher stress for demanding industrial applications.
6. Eco-Friendly and Potable Water Safe​
   • Complies with drinking water standards (e.g., ISO 4422), featuring non-toxic, UV-resistant material suitable for freshwater systems.

Typical Uses of PPH Positive Cross Tube​

• Water Distribution Systems​
  Used in municipal and residential water supply networks to create balanced branch connections for fixtures, ensuring leak-free performance without corrosion risks.
• Industrial Chemical Processing​
  Ideal for plants handling acids, alkalis, or abrasive fluids, where its chemical resistance enables safe multidirectional diversion of process streams.
• Agricultural Irrigation​
  Facilitates efficient flow division in large-scale sprinkler or drip irrigation systems, resisting degradation from fertilizers and UV exposure.
• Mining and Drainage​
  Effective in draining corrosive liquids or ventilating gases in mines, thanks to durability and ease of installation in confined spaces.
• Electrical Conduit Systems​
  Provides insulated, four-way junction points for cable protection in electrical and telecommunications installations, safeguarding against moisture and physical damage.
