MAGNAPLAST internal sewer pipe PP 40/315 HTEM gray

MAGNAPLAST internal sewer pipe PP 40/315 HTEM gray is a polypropylene (PP) pipe designed for indoor wastewater and drainage systems. It conforms to HTEM dimensional standards for 40/315 pipes and is intended for use in internal sewage installations where chemical resistance, low weight, and ease of handling are required. The gray finish is suitable for concealed and exposed runs within residential and commercial buildings and for both vertical and horizontal configurations.

Advantages

The pipe material provides resistance to common household and commercial wastewater chemicals while maintaining dimensional stability over time. Its PP construction results in a low weight that simplifies transport and installation compared with heavier materials. Smooth internal surfaces reduce the risk of deposits and support consistent flow. The HTEM-compatible design ensures compatibility with standardized fittings and connection systems used in internal sewer networks.

Suitable for

• Indoor wastewater and drainage systems in residential buildings
• Internal sewage installations in commercial premises
• Vertical soil stacks and horizontal drain runs
• Retrofit and new-build plumbing projects

Key specifications

• Material: polypropylene (PP)
• Designation / nominal size: 40/315 HTEM
• Color: gray
• Application: internal wastewater and drainage systems
• Properties: chemical resistance, low weight, smooth internal surface

How to use

Select pipe lengths and fittings that match HTEM 40/315 dimensions and intended routing. Cut pipes squarely and deburr edges before assembling. Use compatible seals or socket connections designed for HTEM systems to ensure tight joints. Support horizontal runs at regular intervals to prevent sagging and secure vertical stacks to structural elements as required by local installation rules. Follow standard plumbing practices for venting, slope, and access to cleanouts.

Usage recommendations

Store pipes in a dry, shaded area away from direct sunlight to avoid unnecessary UV exposure. During installation, avoid excessive mechanical stress or impact to preserve dimensional integrity and sealing surfaces. For long-term performance, inspect joints after initial commissioning and during routine maintenance to confirm leak-free connections.
