We can split Carbon steel AWWA C207 Standard flanges in to two types of AWWA flanges i.e. Carbon steel AWWA C207 Standard Ring Flanged connections and Carbon steel AWWA C207 Standard Hub Flanged connections. These carbon steel flanges have been used in low pressure pipe line applications since a long time back and were required for the installation of flanged appurtenances, like carbon steel valves in the pipe line. These carbon steel ring or hub flanges were not manufactured to any particular standard and were riveted to the pipe barrel in those early days. As the use of low pressure steel pipe line works increased gradually, by the time the need for standardization of carbon steel low pressure ring flanges increased. Prior to 1950, these all carbon steel low pressure flanges were designed according to ASME specifications.

Carbon steel flanges complying with these ASME standards were manufactured to dimensions that can have a minimum pressure rating of 275 psi, which is in excess of pressure requirements needed for low pressure pipe line applications. In 1945, the ASME and the AWWA established a committee to develop a standard for these low pressure steel flanges for use in the piping industry that were compatible with the pressures, temperatures and dimensions normally encountered in supply piping systems.

During the latest revision to AWWA C207, and during the development of AWWA Standard C228, questions were presented relative to the design basis for AWWA carbon steel ring flanges. The discussions presented during this revision period focused on dimensional, primarily flange thickness, differences between AWWA and ASME carbon steel ring flanges. The pipe wall thickness is a critical component relative to carbon steel flange stresses.

We are manufacturers and suppliers of Carbon steel forged reducing flanges , designed in compliance with international quality standards API 6A and/or ASME B16.5 standards.We are manufacturing these Carbon steel flanges in all types and pressure classes.

These Carbon steel reducing flanges are widely used for pipe-to-pipe connections. These reducing forged flange includes a Carbon steel flange with one specified diameter or standard size having a bore of a different standard size and smaller diameter .Except for the bore and hub dimensions, this Carbon steel reducing flange have all dimensions of the larger pipe size only.
These forged Carbon steel flanges are used at the outlet side of the expansion joint to increase the size of the Carbon steel flange, . These Reducing Flanges also facilitates the most economical method to make a transition in size.
Carbon steel Reducing Flanges are suitable for changing line size, but engineers should make ensure that these flanges should not be used if abrupt transition would create undesirable turbulence, as what like at pump connections.

Size Range in Carbon Steel Reducing Flanges:

• to Up to 30 Subject to the size and standard specifications of the Flange.

Carbon Steel flangesare being made of low alloy carbon steel metals i.e. plates and forgeable solid bars. Carbon Steel flanges are corrosive in nature but very reasonable priced metal.

Making of Carbon Steel Flanges

Carbon Steel flangesmanufacturing is bit easy in comparison to other steels and alloys like Stainless Steel, Alloy Steel and Super Alloys like Monel, Inconel, Hastelloy, Titanium etc. Forging Carbon Steel is also quite easy because the hardness of this metal is very low in comparison to above said metals. In simple words machining of CS Flanges is easy as far as tooling is concerned and that is why production of Carbon Steel flanges is much higher in comparison to stainless and other metal flanges.

Applications of Carbon Steel Flanges

Carbon Steel is a low temperature metal, In air and moisture these flanges gets rusted. That is why CS Flanges can not be used where chemical or saultey atmosphere is there. For example Costal area, acid plants etc. But Carbon steel flanges are being consumed much more in comparison to any other metal flange because of price factor.

Carbon Steel flangesare being used in Commercial as well as non commercial sectors like Structural applications, construction, Automobile Industry Water and Drainage applications, Oil & Gas industries etc.

We would like to mention here that some peoples do use carbon steel flange in anti corrosive or some critical applications also by cladding required metal on these flanges.

Carbon Steel Threaded Flanges are basically used at the end of pipe or fittings with the concept of opening and closing the same for cleaning, inspection or some other purpose.

Carbon steel forged threaded flangesare meant for connecting pipes, valves, pumps and other equipment to form a piping system. Threaded Flanges do provides easy access for cleaning, inspection and modification.

These carbon steel forged flanges are available with us in many surface finish like varnished as what we can see in the above image. this carbon steel threaded flange is varnished. We can also manufacture and supply black finish, painted or galvanized or hot dip galvanized finish carbon steel forged threaded flanges in India.

Carbon steel Threaded Flangesare used for special circumstances with their main advantage being that they can be attached to the pipe without welding. Sometimes a seal weld is also used in conjunction with the Carbon steel threaded connection.

Carbon steel threaded flanges available in all most all sizes and pressure ratings, screwed (threaded) fittings today are used almost exclusively in smaller piping sizes.

A Carbon steel threaded flange is not suitable for a pipe system with thin wall thickness, because cutting thread on a pipe is not possible in such case. Thus, thicker wall thickness must be chosen according to the type of threads. ASME B31.3 Piping Guide indicates very clearly that where Carbon steel pipe is threaded and used for steam service above 250 psi or for water service above 100 psi with water temperatures above 220 F, the Carbon steel pipe shall be seamless and have a thickness at least equal to schedule 80 of ASME B36.10.

Carbon Steel Ring Type Joint (RTJ) forged flanges have grooves cut into their faces which accept steel Ring Gaskets. Carbon steel RTJ flanges seal when tightened bolts compress the gasket between the Carbon steel flanges into the grooves, creating a metal to metal seal, deforming the gasket to make Intimate Contact inside the grooves.

Carbon Steel A105 Ring Type Joint Flange Size Range :

• NB to Up to 60 NB Subject to Type of RTJ Flange.

lwn flange These Carbon steel flanges have have a uniform Long Weld Necks barrel outside diameter that provides a nut relief clearance between the connection neck and the nut. Lengths of these Carbon steel forged LWN flanges can be increased to allow for any offset, "hillside" or heads or tangential location attachment on pressure vessel shells etc. Contoured bottoms can be manufactured and supplied on request.

Carbon Steel Socket flangesare being made of carbon steel metals i.e. carbon steel plates and or forgeable solid bars. These flanges are exclusively designed for the purpose of welding the flanges to the subject. For example it will be welded to the end of pipes and not screwed up to pipe as it don't have threaded in it's inner diameter. In other words the internal diameter of thesecarbon steel socket weld flangesare not through, there is step in it's inner diameter with suitable dimensions to it's pipe to be fitted with.

Carbon steel Socket Weld flangeswere initially developed for use on small-size high pressure piping. These flanges static strength is equal to Carbon steel Slip On flanges, but their fatigue strength 50% greater than double-welded Carbon steel Slip On flanges.

The connection with the pipe is done with 1 fillet weld, at the outside of the Carbon steel flange. But before welding, a space must be created between Carbon steel flange or fitting and Carbon steel pipe.

ASME B31.1 1998 127.3 Preparation for Welding (E) Socket Weld Assembly clearly indicates thatin assembly of the joint before welding, the pipe or tube shall be inserted into the socket slot of these Carbon steel flange to the maximum depth and then withdrawn approximately 1/16" (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket of this Carbon steel flange.The purpose for the bottoming clearance in a Socket Welding is usually to minimize the residual stress at the root of the weld that could occur during welding operation of the weld metal. The below mentioned image shows you the X measure for the expansion gap for Carbon steel socket weld flange.

Carbon Steel Weld neck Orifice forged Flanges are typical type of weld neck flange having one drainage point on the outer diameter of the flange.Carbon Steel Weld neck Orifice Flangesgenerally come with either Raised Faces or Ring Type Joint (RTJ ) facings. For all intensive purposes these flanges are the same as weld neck and slip-on flanges with extra machining. Weld neck Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline. Pairs of pressure "Tappings", mostly on 2 sides, directly opposite each other, are machined into the orifice Weld neck flange. This makes separate orifice carriers or tappings in the pipe wall unnecessary.

Carbon Steel 8 blinds or Spectacle blinds consist of a ring (spacer) and a plate (spade). In the event of an item of equipment being shut down, the plate covers the ring to form an airtight seal. Our spectacle blinds are designed to ensure that an item of equipment can be securely blanked off, with no possibility of leakage in the valve.The name spectacle blind comes from the spectacle like appearance of the device and the name 8 blind originates from the two circular discs used to make the device. They are generally installed as a permanent device to separate process piping systems. They are often used along with block and bleed valve assemblies meant to provide positive isolation for maintenance on the process facilities. After that block and bleed valve is closed and equipment is depressurized and drained, the 8 blind spectacle blind can be rotated into close position to provide additional isolation from process fluids entering the maintenance area.We are proud to establish ourselves amongst the leaders of market as Carbon Steel 8 blinds Manufacturer and Suppliers .
