Slip On Flanges

The Slip-On Flange Is Positioned So The Inserted End Of The Pipe Or Fitting Is Set Short Of The Flange Face By The Thickness Of The Pipe Wall Plus 1/8 Of An Inch, Which Thus Allows For A Fillet Weld Inside The So Flange Equal Without Doing Any Damage To The Flange Face. The Back Or Outside Of The Slip-On Flange Or So Flange Is Also Welded With A Fillet Weld.

Slip-On Flanges Or So Flanges Are Commonly Lower In Price Than Weld-Neck Flanges, And To This Effect Are A Popular Choice For Our Customers. 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. Moreover, Weld-Neck Flanges Have A Higher Life Expentancy Than Slip-On Flanges Under Duress.

Slip-On Flanges Are A Popular Type Of Pipe Flanges. These Are Type Of Flanges That Slide Over The End Of Piping And Then Welded In Place. These Flanges Are Ideal For Lower Pressure Applications. These Are Easily Fitted And Welded Into Different Pipes. Welding Reduces Fabrication Costs Of These Pipes. These Are Available In Wide Variety Of Sizes And Applications.

Socket Flange

Socket Flange, A Popular Type Of Pipe Flange, Was Initially Developed For Use On Small-Sized High- Pressure Piping. The Fabrication Of This Type Of Flange Is Similar To That Of A Slip-On Flange. However, The Internal Pocket Of A Socket Flange Allows For A Smooth Bore And Better Fluid Flow. When Provided With An Internal Weld, The Static Strength Of This Flange Is Equal To Slip-On Flange, But The Fatigue Strength Is 50% Greater Than Double Welding Slip-On Flanges. Smooth Bore Conditions In Such A Flange Can Easily Be Attained Without Having To Bevel The Flange Face And, After Welding, To Reface The Socket Flange As Would Be Required With Slip-On Flanges. For This Reason, The Internally Welded Flange Is Popular In Chemical Process Piping.

The Recess On The Inside Diameter Of The Socket Flange Allows For A Good Fit Of The Pipe Allowing For A Smooth Flow Of Liquid. Socket Flanges Work Well For Smaller Sizes And Higher Pressure Temperature Conditions. They Are Similar To Slip-On Flanges, But Must Specify The Schedule Of The Pipe Where They Will Be Used For With Socket Flange.

Socket Weld Flanges

Socket Weld Flanges Are Similar To Slip-On Flanges, However, Socket Welds Have An Internal Recess On The Inside Diameter To Allow For A Smoother Flow Of The Process Fluid. The Positive Of This Is That Is Creates A Smooth Bore With The Proper Welding And Grinding. The Negative Of This Type Of Flange Is That It Can Be More Expensive Than A Slip-On Due To More Intricate Machining, And They Can Be Less Readily Available Than Slip-Ons Due To The Fact That The Bottom Half Of The Inside Diameter Must Be Made To The Same Schedule As The Pipe That Is Being Used. (You Must Specify The Schedule Needed) These Socket Weld Flanges Were Initially Developed For Use On Smaller Sizes Of Pipe At Higher Pressure Ratings. They Are More Used On Lower Pressure Temperature As Well Today.

Hitesh Steel Offers These Flanges In Stainless Steel, Alloy Steel, and Carbon Steel.

Key Features:

The Recess On The Inside Diameter Allows For A Good Fit Of The Pipe Allowing For A Smooth Flow Of Liquid
Work Well For Smaller Sizes And Higher Pressure Temperature Conditions.
Similar To Slip-On Flanges, But Must Specify The Pipe Schedule They Will Be Used For With Socket Welds

Stainless Steel Spectacle Flange

Separating one part of a line from another requires a spectacle blind, able to switch from closed to open and back again. Bleed rings provide a means to release pressure from the pipe through a controlled opening. Spectacle flanges are known for their tensile strength, dimensional accuracy and durability. These flanges are made by using best quality material. We offers an extensive range of spectacle flanges in various dimensions and specification.

These types of flanges are made from plate, and come in 3 different types:

The first and most widely used type are spectacle blinds. These are flanges with two equal outside diameter (od) parts welded together by way of a ‘bridge’. One of the parts also contains an inside diameter (id), while the other is a blank, or blind. A whole is put at the halfway mark of the bridge.

The second and third types are quite similar: both have longer bridges, referred to as ‘paddles’, which resemble longer handles. One type has only an od, and so is a blind plate – similar in appearance to a large pizza oven peel. These are referred to as paddle blinds.

The other type is exactly the same but comes with an id as well, enabling flow-through when installed in a piping system. These pieces have holes in the paddle which enables field personnel to determine by sight which piece is installed in a system. These are referred to as paddle spacers, and are often supplied in sets together with the paddle blinds.

All 3 types of these flanges are used in piping systems or pressure vessels where the flow needs to be interrupted from time to time. They are installed between two pipe flanges (as specified above), and by way of a screw inserted into the hole in the bridge or paddle, they are able to rotate or ‘swing’ into and out of position to interrupt or allow the flow, as the user sees fit. Our spectacle blind flanges are available with raised, flat, or rtj faces.

This is a flange plate which as its name implies is shaped like a pair of spectacles only in this case one spectacle is open and the other is blanked off. This plate is installed in the pipeline between a pair of flanges. In normal operation the plate is installed with the open side in the pipeline so it does not restrict the flow. However, once the pressure has been taken off the flange plates can be loosened and the spectacle plate changed to put the blind side in the flow. This will completely seal off the flow making the line safe to work on.

ANSI Flanges

Flange dimensions are determined by pipe size and pressure class required for the application. Most of these dimensions have been standardized and published as ASME, MSS, API or other standardization organization specifications.

ASME/ANSI B16.5 provides dimensions and tolerances for flanges in pipe sizes from 1/2" through 24" and in classes ranging 150 through 2500.

A Flange is an external or internal ridge, or rim (lip), for strength, as the flange of an iron beam such as an i-beam or a t-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc. , or on the lens mount of a camera; or for a flange of arail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. The term "flange" is also used for a kind of tool used to form flanges. Pipes with flanges can be assembled and disassembled easily.

There are many different flange standards to be found worldwide. To allow easy functionality and inter-changeability, these are designed to have standardised dimensions. Common world standards include asa/ansi/asme (usa), pn/din (european), bs10 (british/australian), and jis/ks (japanese/korean).

In most cases these are not interchangeable (e. G. An ansi/asme flange will not mate against a jis flange). Further, many of the flanges in each standard are divided into "pressure classes", allowing flanges to be capable of taking different pressure ratings. Again these are not generally interchangeable (e. G. An ansi/asme 150 will not mate with an ansi/asme 300).

These pressure classes also have differing pressure and temperature ratings for different materials. Unique pressure classes for piping can also be developed for a process plant or power generating station; these may be specific to the corporation, engineering procurement and construction (epc) contractor, or the process plant owner. The ansi/asme pressure classes for flat-face flanges are 125# and 250#. The classes for ring-joint, tongue & groove, and raised-face flanges are 150#, 300#, (400# - unusual), 600#, 900#, 1500#, and 2500#.

The flange faces are also made to standardized dimensions and are typically "flat face", "raised face", "tongue and groove", or "ring joint" styles, although other obscure styles are possible. Flange designs are available as "weld neck", "slip-on", "lap joint", "socket weld", "threaded", and also "blind"

Forged Steel Flanges

A 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.

Hitesh steel manufactures flanges in a whole range of materials. These are manufactured, fully forged to ansi b16. 5, ansi b16. 47 series A, mss sp 44, bs 4504, api 6a, and api 17d.

Ring Joint Flanges

These stainless steel ring joint flanges are highly appreciated for strength, durability, reliability, corrosion resistance and close tolerances. These steel ring joint flanges conform to various indian and international quality standards. Used in a number of industries, these steel ring joint flanges are supplied in various dimensional specifications.

This type of use as a seal ring of steel called a ring joint. Fabricated ring groove on the surface of the flange with the specification that has been set based on international standards. Surface of the ring type joint is very expensive and most appropriate use for the service with a high pressure because internal pressure increases the sealing force of the ring joint.

Ring joint flange is a special type of flange connection in which a metal ring (resting in a groove in the flange) serves as a pressure seal between the two flanges. Rtj flanges seal when tightened bolts compress the gasket between the flanges into the grooves, deforming (or "coining") the gasket to make intimate contact inside the grooves, creating a metal to metal seal.

Welding Neck Flanges

The welding neck flange derives its name from the neck portion of the flange that is welded to the end of a piping system.   it is designed to transfer stress to the pipe, thereby reducing high stress concentrations at the base of the flange. Weldneck flanges are costlier due to their design and engineering, and increased material

Weld neck flange is flanges that designed to be joined to a piping system by butt welding. This kind of flange include lots of specification, welding neck flange is expensive because of its long neck and cost of people for contact wn flange with pipeline or fitting, but is preferred for high stress applications. The necks, or hubs, transmits stresses to the pipeline. The gradual transition of thickness from the base of the hub to the wall thickness at the butt weld provides important reinforcement of the weld neck flange. The bore of weld-neck flange matches bore of the pipeline, reducing turbulence and erosion.

Our weldneck flanges are available with raised, flat, or rtj faces, and are also available in orifice configurations.

These flanges are available in all of our stainless steel and chrome-moly grades, from ½” to 36” and beyond, class 150 to 2500.
