PP Branch 45° SN8

  Datasheet (PDF)

The PP branch 45 degrees SN8 SDR34 is an unplasticised polyvinyl chloride fitting engineered for non-pressure underground gravity sewer and stormwater networks. Designed for municipal and industrial utility infrastructure subjected to medium and heavy traffic loads, this fitting provides a reliable 45-degree lateral connection. Featuring an integrated socket joint with factory-fitted EPDM elastomeric sealing rings, it ensures durable, leak-tight connections across pipeline diameters ranging from d125 mm to d800 mm.

Technical specifications

The PP 45-degree branch provides high structural rigidity with a nominal ring stiffness rating of SN8 (8 kN/m²) and SDR34 dimensions. Manufactured from premium PVC-U compound, the fitting offers exceptional hydraulic efficiency and broad chemical tolerance for aggressive wastewater streams.

With an extremely smooth interior surface roughness of less than 0.01 mm, the fitting prevents internal encrustation, sediment accumulation, and flow loss. The unplasticised material exhibits high mechanical resistance to soil stresses and handles effluent temperatures up to 60 degrees C for short-term or continuous operational discharge.

• Ring stiffness: Class SN8 (8 kN/m²), SDR34 dimensional ratio
• Material: Rigid unplasticised polyvinyl chloride (PVC-U) in orange RAL 8023
• Sealing system: Socket connection with high-durability EPDM elastomeric gasket
• Chemical resistance: Suitable for acidic and basic effluents within pH 2 to pH 12
• Temperature limit: Working operating temperature up to 60 degrees C
• Internal roughness: Hydraulic roughness coefficient below 0.01 mm

Applications

This PP 45-degree branch is engineered for underground gravity drainage networks installed outside building structures in infrastructure application area code U. It serves as a primary branching node for municipal foul sewerage, industrial wastewater conveyance, and highway storm water discharge systems.

Owing to its SN8 heavy-duty ring stiffness, the fitting is rated for buried installations beneath roads carrying medium to heavy traffic loads at depths from 0.8 m up to 6.0 m. It maintains mechanical stability and structural performance under static soil overburden and dynamic transit loads in accordance with civil engineering designs.

Installation and jointing

Jointing is performed quickly and securely using the push-fit socket system equipped with pre-inserted EPDM synthetic rubber gaskets. The elastomeric seal accommodates minor pipe movements and permissible structural deflections without compromising network watertightness.

Assembly requires applying an approved pipe lubricant to the rubber seal and the chamfered spigot end before pushing the joint fully home. Bedding, trench installation, and backfilling must follow EN 1610 standards to guarantee full load transfer to the surrounding soil envelope, preventing localized stress concentrations during service.
