Product description

Malleable iron pipe fittings are suitable for pipeline connections with nominal sizes (DN) ranging from 6 to 150, operating temperatures from -20°C to 300°C, and a maximum working pressure of 2.5 MPa. They are an essential component of pipeline systems in the gas, fire protection, water, and HVAC sectors, capable of meeting the connection needs of various pipeline systems. Whether for straight pipelines or curved pipelines, or for pipelines of the same or different diameters, malleable iron pipe fittings provide a secure and reliable German standard threaded connection, facilitating on-site construction.
