ASTM A182 F304 Spectacle Blind ASME B 16.48

What is a Blind Flange,what about its specification and its advantages

ASME B16.5 flange is a flange made accoding to American matal standaed.Class 150 WN flange is the lowest pressure of flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

The descipton ,specification ,and advantages of a weld neck flange.

A weld neck flange is a type of flange that connects, seals, and changes the direction of a pipe in a pipe system by butt-welding the flange to the pipe. The neck of the weld neck  flange matches the outer diameter of the pipe, providing a good welding interface during welding to ensure the strength and tightness of the connection.

It is generally used in non-corrosive, non-critical, moderate pressure services. Slip on flanges of Class 150 and Class 300 are most commonly seen in utility engineering. Similar to welding neck flange, the slip on flange conforming to ASME B16.5 may generally be furnished with three facing types: raised face (RF), flat face/ full face (FF), or ring type joint (RTJ).

The descipton ,specification ,and advantages of a weld neck flange.

All flanges are round disks with holes for bolts around the rim, but the commonalities end there. a projecting flat rim used for strengthening or attachment.

Weld Neck Flanges are a very common type of pipe flanges used in various industrial applications. They have a long tapered hub and are often used for high pressure applications.

A182 F304 slip on flange include flanges, bolt holes and sealing surfaces. The flange is a flat ring structure with an outer diameter larger than the outer diameter of the pipe connected to it. The bolt holes are evenly distributed on the flange and are used to install bolts to connect two flanges.

Class 1500 SO flange Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.Flanges have five face types:RF RTJ FF MF TG. Slip on flanges can slip on the pipes and welding with the pipes.

Stainless steel flange is popular because stainless steel has great anti-corrosive function.Flanges can be many types:WN,SO,SW,THD,LAPJ,BL.These flanges use different connections to connect with the pipes.Shanghai Zhucheng is a high quality manufactory who can supply all types of flanges.

What is a Weld Neck(WN) Flange and what about its specification and advantages.

An assembly with limited space may be an instance in which a socket weld is selected, provided the pressure class is comparatively low and the fluid is not corrosive or for extremely high temperature service.

The specification of ASTM A182 Forged Pipe Fittings includes forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.

Slip on flange, also called SO flange. It’s a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly connected to equipment or pipe by fillet weld at the top and bottom of the flange. It is used to insert the pipe into the inner hole of the flange.

Detail infoemation of Weld Neck(WN) Flange

ASTM A182 F304 spectacle blind is more often used than carbon steel spectacle blind as its great anti-corrosive function.ASME B16.48 is the standard of spectacle blinds.The two components have different functions in the piping system.

These Stainless Steel A182 Threaded Union are best known for their heat resistance, creep strength and tensile strength. Machined and fabricated to meet your diverse piping requirements, these pipes fittings exhibit excellent corrosion resistance in a wide range of atmospheric environments.

There are varies advantages of stainless steel flange:
Resistant to corrosion and staining
Low maintenance
Bright familiar luster
Steel Strength

orged steel flange is a disc-shaped piece of equipment used to connect a pipe to fittings or valve or other component to form a pipework system. Usually flange has been attached to pipe or tube end to, and then a gasket is inserted in the middle to form a seal. Finally they are joined together with bolts and nuts.

Threaded nipple is a short piece length of pipe or tube. Its size is specified according to the length of this section of pipe and the diameter. It can be with threaded or flat ends. And both ends can be the same or different.
There are two shape : threaded one end (TOE) and threaded both end ( TBE).

A flange can be defined as a method that helps in connecting pipes, valves, etc., to form a full piping system. There are six flange classes ranging from #150 to #2500. Governed by B 16.5 standards, the ASME B16. 5 Class 300 Flange provides a pressure capacity of 300Lb.

The smooth transition between the flange and the hub combined with the strength of the butt weld joint, allows the flange to be used in extreme conditions of cyclic loading, bending and temperature fluctuations.

ASME B16. 5 pipe flanges: Weld Neck Flange ( WN),Slip-on Flange (SO), Threaded Flange (THD),Socket Weld Flange (SW),Blind Flange (BL),Lap Joint Flange (LAPJ),Plate flange (PL)

Threaded Flanges are also known as screwed flange, and it is having a thread inside the flange bore which fits on the pipe with matching male thread on the pipe.

What is a WN Flange?and what about its specification

Class 150 F316 slip on flange is a common pipe connection element, mainly made of stainless steel material, through slip on and pipe or other flanges are connected. slip on flange is generally composed of flange plate, bolt hole and sealing surface.

The bore of the slip on will give ample amount of space for the matching pipe. This allows for enough working space for the welder and fabricator to make the connection.Slip-On flanges are commonly lower in price than weld-neck flange.However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation.
