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.
