A better connection from AVIT

MAWO PIPEFITTINGS

AVIT couplings are suitable for connecting high pressure steel pipes. The company’s screw pipe connections are based on the tried and tested 24° cone system. The 24° cone is connected to the end of the steel pipe by means of a butt-welded joint, while the welded hexagon nipple or the screw socket is welded or screwed with the construction. The extremities of the pipe are centred when they are assembled by screwing, and are connected to each other by longitudinal friction-coupling when the nut is tightened. Standard pressures are: 160, 250, 320 and 400 bar. Double sealing provides double safety for the connection. The screw coupling shows minor signs of settling on account of the wedge action.

SPECIAL PIPEFITTINGS

There are no lateral forces so that slackening is impossible, and notch effects have no influence.

AVIT’s couplings are S S available for pressures up to 400 bar

These properties, combined with rotation-symmetric preloading force, result in long-term leak tightness. The screw mounting can be repeated often without deformation of the components. All parts are standardised (DIN/ISO 8434-4).

Changes to all tube dimensions up to 50mm external diameter can be realised with AVIT reduced welding cones.

Dimensions for tubes according to DIN 2448 are also standard. Providing couplings are mounted correctly, AVIT guarantees five years of secured pressure in single shift operation.
