Flanges

All Truco steel flanges are manufactured from high-grade, durable carbon steel (carbon steel flanges), making them ideal for use with highly abrasive, high-wear applications across all types of pipework – from 40 to 1 000 mm nominal bore. Custom-sized flanges are made to order.

Our 125 years of experience in working with high-quality hose-to-hose flanges; hose-to-HDPE piping flanges; and hose-to-steel pipe flanges, means we have the know-how to ensure you get the ideal flanges that exactly meet your specific application requirements.

Split Flange Coupling

Made from high-grade, corrosion-resistant aluminium alloy, these aluminium flanges are widely used in hard-wall pulp & slurry mining hose applications. Designed to handle pressures up to 1 000 kpa, a reusable coupling can be fitted to any length of hose or pipe onsite. This means the need to stock various hose lengths with built-in flanges is negated, ultimately reducing downtime in operations and increasing throughput while also reducing inventory. The Truco split flange coupling is available for hose sizes from 76 to 610 mm without a flange adapter, and is compatible with all major flange standards.

Frequently Ask Questions

 

What are flanges?

A flange, or flange connection, is used to join pipes, hoses, or tubes that have an outside diameter of more than 178 mm (7 inches) when under very high pressure. Those that aid with exceptionally high pressures are called high pressure flanges.

What are flange types?

When two pipes or  hoses need to be connected (and when connecting a hose to a pipe or a pipe to a hose), a pipe flange (also called connecting flange) is used to make the connection. Flanges are collars (or rims) that protrude from the pipe that enables it to be bolted or welded (flange weld) to the connecting pipe or hose. This helps ensure a leak-free connection between the two pipes or hoses. To guarantee a leak-free connection a gasket can be placed between the connecting flanges.

Where are flanges used?

When joining a pipe and a hose, or a pipe to a pipe or a hose to a pipe, flanges are bolted or screwed into the pipe or hose. The pipe or hose is then bolted to the flange on the other hose or pipe that needs to be joined. In the case where a secure seal is needed, a gasket is placed between the two bolted flanges, ensuring leak-free transportation of your high-pressure application.
