Definition Of Weld Neck Flange:
Weld neck pipe flanges attach to the pipe by welding the pipe to the neck of the pipe flange.These flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint ...
Weld Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.
Uses of Weld Neck Flanges:
Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. When ordering a weld neck flange, it is ...
ANSI/ASME B16.47 Long Weld Neck Flange/Integral Flanges
SPECIFITION:
Long weld neck flange(LWN flange) is also call integral flange, it means a welding neck flange has a very long neck . Commonly, the welding neck flange has a tapered neck and a bevel end which is going to butt welding with the ...
A weld neck flange (WN flange) means a flange has a neck for weld with the pipe, it is easily to recognized by their long tapered neck on the flange (The neck is also called hub in the weld neck flange). The tapered neck can supply a high strength reinforcement to support flange and pipe. It mea ...
ASME B16.47 Carbon Steel RF Weld Neck Flange
Uses of Weld Neck Flanges:
Weld Neck Flanges have a long tapered hub and are often used for high pressure applications. When ordering a weld neck flange, it is important to specify the schedule pipe is being used for. This is because the inside diamet ...
Definition Of Weld Neck Flange
Weld neck flange (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant.A weld neck flange consists of a circular f ...
Weld Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.

Integral Flange(Long Weld Neck Flanges) are used for high pressure situations, integral hub weld neck flanges are used and for very high pressure cases Long Welding Neck flanges are preferred. In this case, the weld are far from the ring to avoid bending stresses and weld stress being combined ...
Weld Neck Flange
Weld Neck Flanges are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting.
The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated ...
Pate flanges are secured to the pipe with a fillet weld at the bottom and the top of flanges with the pipes.The welding method is fillet weld,so the plate flange is not suitable for a high pressure application.
We mainly produce plate(flat) flange according to standards:ANSI/ASME B16.5,EN1092-1, ...
Plate flange (Plain flange) is also called flat flange, plate slip on flange or a ring flange. It looks like a flat circular disk with inner bore and bolt holes on it . It is one kind of the slip on flange.We mainly produce plate flange according to ANSI/ASME B16.5,EN1092-1,JIS B2220,BS4504,DIN, ...
