Pipes and Fittings – Complete Selection and Application Guide

Pipe dimensions – choosing the right diameter

Pipe diameter is selected based on installation purpose. For residential drainage, standard sizes are 110mm and 125mm, while 200mm and larger dimensions are used for collectors and industrial systems. For water supply, pipes from 20mm to 32mm are most commonly used for distribution within buildings.

Drainage pipes – PVC or PP

PVC pipes are an economical choice for standard drainage, resistant to corrosion and easy to install. PP pipes withstand higher temperatures (up to 95°C) making them suitable for sink and washing machine connections. Always use correctly sized fittings – 110mm pipes require matching 110mm elbows, tees and reducers.

Copper system for water and heating

Copper piping guarantees longevity and hygiene in water supply installations. Copper fittings are soldered or press-fitted for permanent leak-proof joints. For heating installations, copper excellently transfers heat and withstands high temperatures without deformation.

Types of fittings and their applications

Fittings are connecting elements without which a functional system cannot be formed. Elbows enable direction changes, tees split the flow, adapters and reducers connect pipes of different diameters, and caps close pipe ends. Brands like CALEFFI offer quality brass and copper fittings for specialized applications.

Flexible pipes and ALUFLEX systems

ALUFLEX pipes combine aluminum flexibility with protective plastic layers, ideal for ventilation and hot air distribution. They allow bending without additional fittings, which simplifies installation in tight spaces and reduces the number of potential leak points.

What to check before purchasing

Verify material standards – black steel pipe for gas must have wall thickness according to EN 10255 standard, PVC pipes carrying EN 1401 marking for drainage or EN 1452 for pressurized water supply. Always purchase the same system of pipes and fittings from one manufacturer to ensure full compatibility of joints.
