Product Description


A Weld Neck Flange (also known as a high-hub flange and tapered hub flange) is a type of flange.

The Welding neck flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange.

A 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 fitting with a protruding rim around the circumference. Generally machined from a forging, these flanges are typically butt welded to a pipe. The rim has a series of drilled holes that permit the flange to be affixed to another flange with bolts.

WELDING NECK FLANGE NPS 6, CLASS 150, SCHEDULE 40, Asme B16.5 / ASTM A105

WELDING NECK FLANGE NPS 6

The flange above has 8 bolt holes, and a welding bevel of 37.5 degrees (red circle). All given dimensions are in millimeters. The raised face (RF) does not need to be specified, because according to ASME B16.5, each flange is standard delivered with a raised face. Only a different design (Ring Type Joint (RTJ), Flat Face (FF) etc.), should be specified.


The welding neck flange is the best designed butt-welded flange of those currently available becuase of its inherent structural value.

Forged Steel Flange are perfectly finished with precision using the latest machinery.

Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.
Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

Forged Steel Flanges are made in seven primary ratings: Class 150, Class 300, Class 400, Class 600, Class 900, Class 1500 & Class 2500

                         

Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard. Dimension to be in accordance with JIS ANSI DIN BS standard accordingly.

The flanges are suitable for connection of steel pipes conveying mediums such as steam, oil, air and water. They are widely used in Chemical industry and Shipbuilding . And the flanges are suitable for welding.The flanges mainly include Welding Neck, Blind, Slip-on, Lap-Joint, Socket,Reducing and Plate type.

Size available: 1/2"--72"(DN15-DN1800).

Materials:
CARBON STEEL:
ASTM A105, A350-LF1, LF2, LF3 ASTM A181-60 etc
ALLOY STEEL:
ASTM A182 F9 F11 F22 etc.
STAINLESS STEEL: 
ASTM A182 F321, F304, F304L, F316, F316L  etc

Forged flanges are manufactured in all the different materials to match the material of the pipe and fittings to which they are being attached. While some flanges are made of Cast Iron, the vast majority of flanges are forged carbon steel.

                                 150LB Carbon steel forged flange


Forged steel flanges made of carbon steel or stainless steel, the materials conform to the JIS, ASTM A182,A105, DIN17100 ST-2 and BS standard.

In the production, press the mass of the forging parts, the quantity of the batch of different forging methods. Free forging productivity is low, processing surplus is large, but the tool is simple, universality is large, so it is widely-used


Forged flange is the best mechanical properties of a flange product, its raw materials are generally tube, and then after cutting and then continue to beat, to eliminate the ingot in the segregation, loose and other defects. Price and mechanical properties are higher than ordinary casting flange a grade. The flange is a part that connects the pipe with the pipe and the valve, is connected to the pipe end. It is also used for the flange on the equipment inlet and outlet.

Face Type:
Flat Face, Raised Face, Ring Joint Face, Lap Joint Face, Male Face, Female Face, Tongue & Groove Face

Type:
Weld Neck Flange, Slip On Flange, Blind Flange, Socket Welding Flange, Thread Flange, Reducing Flange,Spectacle Blind Flange, Orifice Flange




Expander Flange

Expander-Flange

 Expander Flange is a Welding Neck pipe flange where the nominal size of the non-flanged end is larger than the nominal size of the flanged end. They can be used to change the size of a pipe run. These are usually used to increase the line size to the first or second larger size. This is an alternative to using a separate reducer and weld neck flange combination. The expander flange can be used to connect pipe to pumps, compressors and Valves.


Long Weld Neck Flanges

Long-Weld-Neck-Flanges

 Long Neck Welding (abbreviated LWN) flanges are similar to a standard Welding Neck flange, but the "Neck" is considerably longer. This type is often used as a nozzle for a barrel or column. In addition, there are the type LWN Heavy Barrel (HB) and the Equal LWN Barrel (E); they have a different shape and a thicker "Wall".
NW Long Weld Neck Flanges

NW-Long-Weld-Neck-Flanges

The NW Long Weld Neck Flanges is normally referred to as the high hub flange. It is designed to transfer stresses to the pipe, thereby reducing high stress concentrations at the base of the flange.
Weldoflange, Nipoflange
nipo-flanges
The Weldoflange and Nipoflange is a combination of a Welding Neck flange and a supposedly Weldolet or Nipolet.
