Weld Neck Raised Face Flanges (WNRF)
Weld Neck Raised Face Flanges (WNRF)
Weld neck flanges
The raised face weld neck flanges ( RFWN) are one of the most often used kinds of flanges in the piping sector. Bottom-entry valves are simple to identify because of the straight hub that is identical to the wall thickness (bore) of the pipe. Machining is the process in which flange bore is made to be identical to the ID of the pipe or fitting. This means that there is no transition that accrues from the weld neck flange to the piping and no turbulence appears during the welding neck.
What is a Raised Face Flange, after all?
Raised face is the most common type of seal gasket profile. Here the gasket contact surface is higher than the surface of flanged face. This is the one used creation for weld neck flanges more than the others seals. Consequently, the height of the face is getting varied because of the shapes or diameters of the flanges. Oh, the skull face is on the hub side instead of the opposite of it.
We create weld neck flanges to supply contingency reinforcement for high-stress purposes. The tube flange also supplies the column strength; this together with the tapered neck region helps stress to be distributed very well. It bears low cycle of fatigue during line expansion or anything else that may lead to variable forces.

Quality Control
Quality, as a major factor of our ISO certification, is a vital component of our business. We make it a standard inclusion of our inspection to ensure the work’s quality.
- Marking
- Surface
- Dimension
As Tack DN25 Class 600 ASTM A182 F304 Weld Neck Flange RF is just one such application.
The symbol should be clearly cut, neat and beautiful, “DN25 600# Weld Neck RF SS304 B16.5 831” for example.
Making hand marks and visual touching the object to make sure it is flat and uniform.
Dimension chart give the value which needs to be measured such as outside diameter, thickness raised face diameter and other dimensions, so the values would be compared to the tolerances.
Positive aspects of weld neck-flange.
These flanges are fit to be sourced in environments which have extreme range of temperature, pressure, or numerous kinds of added strains, while their resilience is defined as to an extent of these environmental stresses being shared with the material with which these flanges are welded. Such flanges have been used successfully at up to 5,000 psi.
The function and Pros of weld neck flange.
weld neck flange application.
The weld neck flanges have a tapered hub and therefore are usually used as a high pressure application. Whether working with a weld neck flange, it is very important to specify the schedule pipe is being used. The inside diameter of the flange will match the inside diameter of the pipe as a result of tapered hub and the butt weld joint, this flange will be very resistant to the dishing
A weld neck flange was named that way as the neck portion of the flange is welded to the end of the piping system. It is made with purpose of burden transferring to the pipe in order to avoid high stress concentrations at the bottom of the flange. Making weld neck out of such material makes them costlier.
According to platinex company line, it is mainly concerned with the manufacture of flanges of different kinds. Besides straight cut and forging, we also have different kinds of weld neck flanges, which is machined, drilled and rigorously tested and inspected by professional testing instrument. if you have a need to any welded neck flanges, be sure to take a contact us.
