ASTM A105 Neck Weld Flange

Neck Weld Flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification,Weld neck Flange is expensive because of its long neck and cost of people for contact WN flange with pipeline or fitting, but is preferred for high stress applications. The necks, or hubs, transmits stresses to the pipeline. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the Weld Neck flange. The bore of Weld-Neck flange matches bore of the pipeline, reducing turbulence and erosion.

ASTM A105 Slip on Flange

Slip on flange are slipped over the pipe and welded (usually both inside and outside) to provide strength and prevent leakage. Slip on Flanges are at the low cost end of the scale, and do not require high accuracy when cutting the pipe to length. These slip on can sometimes have a boss or hub, and can be made with a bore to suit either pipe or tube.

ASTM A105 Plate Flange

Blind Flange include lots of kinds, which has no bore, and is used to close piping system. When you open a piping system and Blind flange also permits easy access to a line once it has been closed. The low pressure pipe system be contacted by threaded / screwed. Blind Flange manufacturer antong supplies Blind Flanges, Industrial Blind Flanges, in ANSI B16.5 etc.
