250 flanged cast iron coated with plastic, black color (HDPE sewage system) 371.745.00.1

HDPE Sewer Flange – Durable and Reliable Connection

This cast iron flange, coated with plastic, with a nominal diameter of DN 250, is a key element of the Geberit HDPE drainage system. It provides a solid and tight connection of pipes, guaranteeing long-lasting and trouble-free operation of the installation. It is designed for use inside and outside buildings, as well as in industrial and laboratory facilities.

This flange is characterized by a thickness of 16 mm and an outer pipe diameter of 250 mm. Its design allows connection with Geberit PE collar sleeves, creating an integral part of the system. The plastic coating protects the cast iron from corrosion and weathering, increasing its lifespan.

Universal Application and Chemical Resistance

The Geberit HDPE system, in which this flange is used, is distinguished by its exceptional chemical resistance – it withstands the action of approximately 95% of standard alkalis, acids and chemicals. In addition, the material is resistant to UV radiation, allowing the pipes to be stored outdoors for a longer time without losing properties. This makes this system ideal for demanding environmental conditions.

This flange is used in:

• drainage of water from buildings
• roof drainage installations (gravity and vacuum)
• terrain drainage
• industrial applications
• laying in concrete

Installation and Durability

Installation of the flange requires the use of appropriate machines and tools for butt welding or the use of resistance welding sleeves. The solid cast iron construction combined with the plastic coating ensures high durability and resistance to mechanical damage, such as shocks, drops or impacts. This makes the installation safe and reliable for many years of use.
