PP Double Branch in Two Planes HTDA 67°

  Datasheet (PDF)

The PP double branch in two planes HTDA d110mm 67 degrees is an engineered thermoplastic fitting designed for soil, waste, and rainwater drainage as well as internal ventilation networks in commercial, residential, and industrial facilities. Manufactured in accordance with SR EN 1451-1 from polypropylene, this multi-directional fitting incorporates two inlet branches configured across perpendicular vertical planes at a 67-degree flow deflection angle, enabling compact, simultaneous convergence of dual tributary waste lines into a primary DN110 vertical discharge stack without hydraulic interference. The connection configuration utilizes factory-fitted EPDM elastomeric lip ring gaskets housed in precisely molded socket contours, securing airtight and watertight push-fit push-lock joints that accommodate structural settlement, cyclic vibrations, and axial thermal movement while operating completely free of chemical cements or external mechanical fasteners. Engineered with hydraulically optimized internal geometry featuring smooth bore surfaces with a Manning roughness coefficient of 0.01, the branch effectively inhibits solid particulate accretion, encrustation, and flow turbulence to maintain superior self-cleansing velocities. Polypropylene construction imparts exceptional chemical durability across an aggressive operating range spanning pH 2 to pH 12, providing uncompromising resistance to boiling water discharges, harsh detergents from domestic laundry appliances, commercial kitchen greases, and industrial acidic or caustic waste streams. The fitting demonstrates comprehensive temperature resilience, operating continuously under medium temperatures of up to 60 degrees, safely withstanding intermittent thermal surges reaching 95 degrees, and retaining structural integrity down to minus 15 degrees. With standardized dimensional characteristics including an insertion depth L1 of 40 mm and branch offset L2 of 86 mm, this grey polypropylene component offers high impact strength and an estimated service life exceeding 50 years.
