Product Name: American Standard B16.5
Pressure 600 Raised Face Welded Neck Flange
Features: Butt welding flange (also called high hub flange and tapered hub flange) is a kind of flange. The regular type is used with pipes. Weld neck flanges are designed to transfer stress to the pipe, thereby reducing high stress concentrations at the bottom of the flange. The flange can withstand different pressures at different temperatures. As the temperature increases, the pressure rating of the flange decreases. The concept of flange rating is obvious. Class 300 flanges can withstand greater pressure than class 150 flanges, because class 300 flanges are made of more metal and can withstand greater pressure.
Production process: The manufacturing process of flanges is very complicated, which is completed by multiple departments and supervised by experienced industry experts. From high-quality raw materials purchased from mature and reliable suppliers to strict quality control practices and procedures, we must ensure that only high-quality products that meet industry standards and parameters are produced. The advantage of forged flanges is that the internal structure is uniform, and there are no harmful defects such as pores and inclusions in the casting. At the same time, it can withstand higher shear and tensile forces than cast flanges.
Application scenario: Usually welded neck flanges are widely used in medium and high pressure pipelines. The nominal pressure of the pipeline is between 0.25-2.5Mpa. The sealing surface of the butt-welded flange connection is concave and convex, and the installation is complicated. Therefore, labor costs, installation methods and auxiliary costs are slightly higher.
FAQ:
(1) Is the flange finish standard?
The typical flange surface finish of ANSI B16.5 raised face weld neck flanges is 125 to 250 µin Ra (3 to 6 µm Ra).
(2) How about the pressure that can withstand this?
The flange can withstand different pressures at different temperatures. As the temperature increases, the pressure rating of the flange decreases. Class 300 flanges can withstand greater pressure than class 150 flanges
(3) Is this type of chemical and petroleum used? Which one is it?
Convex weld neck flanges can be used in petroleum, chemical, construction, machinery and other industries.
