Product Description

Asme B16.5 Forged Integral Pipe Flange

Bangdong produce all kinds of flange ,and sell the product to many countries. we Manufacturing inventories an entire line of Carbon and ASME B16.5 Stainless Steel pipe flanges. flange include:
A350 Lf2 Lwn Flange,A105n Weld Neck Flange,Asme B16.5 Forged Flange,Thread Steel Fitting & Flange,Ansi Slip On Pipe Flange

Stainless Steel Raised Facethreaded Flange, Steel Flange Weld Neck Flange,Spectacle Blank Spectacle Blind Flange,

Stainless Steel Plate Flanges, Pandle Spacer Spacer & Spade Flange and etc.

There are six most commonly used flanges, also knows as ANSI Flange, ASME B16.5 Flange.

Steel Pipe Flange Types

Weld Neck Flange

Weld Neck Flange Weldneck Flange

This flange type is designed to be connected by a butt weld connection to the pipe or equipment requiring a flanged joint. Welding neck provides good service under variety of temperature and pressure applications. A weld neck flange must specifiy the pipe schedule for the bore. Due to the welding neck, it is a popular choice on pressure vessels and for creating man-holes etc. These flanges are also knows as ANSI Flange or ASME B16.5 Flange

Slip On Flange

slip on flange Slip on flange

A slip on flange is designed to slip over the end of pipe. It allows for easy positioning before welding. Both the inside and outside of the pipe is welded on the slip on flange. See picture on the right. The pipe is generally inserted all the way, inside the slip on flange, leaving only the gap equivalent to wall thickness of pipe. These flanges are also knows as ANSI Flange or ASME B16.5 Flange

Lap Joint Flange

Lap joint flange Lap-joint flange

A lap joint flange is also knows as Van Stone Flange. This type of flange consists of both a stub end and a flange.The flange itself is not welded but rather the stub end is inserted / slips over the flange and is welded to pipe. This arrangement helps in flange alignment in conditions where non-alignment may be an issue. In a lap joint flange, the flange itself is not in contact with the fluid. The stub end is the piece which gets welded to the pipe and is in contact with the fluid. Stub ends comes in type A and type B. Type A stub ends are most common. Lap joint flange only comes in flat face. People confuse lap joint flange with slip on flange as they look very similar with the exception that lap joint flange has round eges on the back side and a flat face.

Threaded Flange

Threaded Flange Threaded pipe flange

Threaded flange is also called screwed flange or screwed-on flange. This type of flange is used where welding is not an option. Threaded flange is most commonly used on low pressure applications and smaller pipes (up to 4" nominal).

Blind Flange

Blind Flange Blind pipe flange

A blind flange is a solid flange with no bore or threaded hole and is used to close the end of pipe, fittings, valves or equipment. Blind pipe flange is also used for pressure testing equipment. Blind flange comes both as raised face and flat face.

Spectacle Blind Flange

Line and Spectacle Blind Flange

Spectacle and line blind flanges are similar to a blind flange but different because they fit between two flnges. Spectacle blind gets their name from similarity to pair or eye glasses. Once side of spectacle blind is fully closed for complete flow shutt off, whereas the other end is open for full flow. In this setup the blinds can be rotated without having to take the system apart. It also gives visual confirmation if the line is open or close.

Orifice Flange

Orifice Flange

Orifice flange is a special flange and is always used in pairs. It is used in conjunction with orifice plate for measure flow of liquids and gases in a piping system. Orifice flanges are pre-drilled with tapped holes made in the flange rims to accommodate metering pipe. The flange that makes up the orifice flange is usually a welding neck flange. Slip on and threaded flange are also used sometimes as end connection. In an orifice flange, the pipe must be drilled to accommodate the tapped hole through which the pressure is sensed. The picture above illustrates the working of orifice flange in a welding neck flange arrangement.

Reducing Flange

Reducing Flange

A reducing flange changes the line size without adding an extra fitting. The reduction in a reducing flange is always abrupt compared to a reduction that can be achieved .A reducing fla. A 6" by 4" reducing slip on flange will have the flange dimension (outer diameter, bolt circle diameter) of an 6" flange but the hole of a 4" flange. This allows it to mate to an 6" pipe via flanged connection but connect a 4" pipe instead.
