Weld Neck Raised Face Flange Carbon Steel ASTM A105N Class 150 - 2500 Size 1 - 36 Inch
Flange WN RF A105 or Weld Neck Raised Face Carbon Steel Flange is a high-pressure pipe connection component designed with a long tapered neck for joining to pipes via butt-welding. This tapered neck design distributes mechanical stress evenly across the piping line. This component belongs to the primary weld neck flange category that functions to minimize fluid turbulence and prevent stress concentration at connection points.
A105N Weld Neck Flange Product Description
PT Dwitama Sukses Mandiri provides a complete stock of forged piping components conforming to ASTM A105N normalized standards. The normalization heat treatment improves metal microstructure, providing optimal material toughness at ambient and high temperatures. This product connects directly to a seamless pipe to build leak-tight piping systems. Flange face sealing utilizes supporting components such as a gasket and is secured using a stud bolt set tailored to your project pressure rating.
