Brida de cuello soldable
La brida de cuello soldable cuenta con una extensión de cuello y un bisel soldado. Proporciona una conexión de forma natural, ideal para aplicaciones de alta presión y mayor tamaño.
Brida ciega
Las bridas ciegas no tienen orificio ni diámetro interior. Suelen modificarse para incluir roscas NPT o orificios personalizados para funcionar como bridas deslizantes sin buje.
Brida de unión solapada
Las bridas de unión solapada están diseñadas para encajar sobre un conector de extremo corto. Presentan un buje extendido y un radio mecanizado en la base de la cara plana.
Brida deslizante
La brida deslizante está diseñada para alojar la tubería en el centro/orificio, lo que permite la soldadura alrededor del diámetro exterior de la tubería.
Brida de soldadura a enchufe
Las bridas de soldadura a enchufe tienen un receptáculo para insertar la tubería cuando las limitaciones de espacio dificultan el uso de las bridas de cuello soldado.
Brida roscada
Las bridas roscadas tienen un centro roscado NPT hembra para la conexión a tuberías con rosca macho.
