Blue PP-R pipe SDR 11 Table to determine support intervals in conjunction with temperature and outside diameter.
• Short-term temperature resistance of 90 °C. • Long-term temperature resistance up to 60 °C. • Connecting PP-R pipes with connecting elements and pipes from other materials is done through metal inserts made of the highest quality brass. Chemical resistance PP-R and PP-RCT pipes is chemically durable materials. Re-
1.1 MECHANICAL – pipe system made of PP-R The MECHANICAL pipe system made of PP-R offers a non-corroding and long-standing solution for conveying water in enclosed cooling water systems for residential and commercial buildings, such as hotels and shopping centres, as well as for technological cooling purposes in industrial buildings.
Like all plastics, PP-R is a poor heat conductor and is therefore an excellent thermal insulator. FROST RESISTANCE The elasticity of PP-R allows the pipe to increase its section when the volume of the fluid changes as the water freezes. SUITABLE FOR USE IN SEISMIC HAZARD AREAS This feature is recognized by international boards of experts,
