1/2" - 24"TECHNICAL DESCRIPTION
Weld neck flange ANSI B16.5 / Class # 150 are piping elements that are widely used in the construction of steel pipelines and pipe segments used in industry, shipbuilding and ship repair.
They easily differs from the flat flanges with the long cone neck, which gradually passes to a pipe or other fitting joined by a butt weld. The conical neck ensures a smooth transition to the pipe dimmer, which reduces internal material stresses. This makes them suitable for applications with high / low temperature or mechanical stresses.
The inner diameter is with size that match the internal pipe diameter, which reduce pipe corrosion and frictional wear from the passing fluid.
In stock we keep flanges ANSI B16.5 / Class # 150 and # 300, but flanges up to # 2500 can be delivered from different materials on request.
We have the necessary machining equipment, which also allows us to offer flanges with sealing surfaces.
• type of sealing surface A, B2, C, D, E, F
• non-standard sealing surfaces per job
• Profile channels for metal seals (segments) type RTJ
• Threaded flanges
• Flanges made by customer's order, and others.
