A popular category of pipe flange is the blind flange. A blind flange is used to close ends of piping systems. It is a kind of round plate with no center hold but with all the proper bolt holes. This blind flange is available in various sizes and materials and is used to provide positive closer on the ends of pipes, valves or equipment nozzles. This flange helps in easy access to a line once it has been sealed. The blind flange is sometimes custom made or machined to accept a nominal sized pipe to which reduction is being made. This reduction can be a threaded reduction or welded reduction.

Materials used:Some materials used in the manufacturing of blind flanges are as follows:

• Stainless Steel
• Nickel Alloy
• Titanium
• Carbon Steel
• Cast Iron
• Brass
• Bronze
• Steel
• Aluminum
• Polypropylene
• Silicone
• PVC etc.

Features of blind flanges:Some important features of blind flanges are as follows:

• 
  
• Blind flanges are sometimes supplied with NPT fittings which allow pressure test connections to be fitted.
• They are used to blank off the ends of pipe.
• They are also used to blank off the ends of valves and pressure vessel opening.
• Considering factors like internal pressure and bolt loading, blind flanges, especially in the larger sizes, are the most highly stressed of all types of flanges.
• Since the maximum stresses in a blind flange are bending stresses at the center, they can safely be allowed to be higher than in other types of flanges.
• Blind flanges are made to fit standard pipes in all sizes.

Plate flanges are special types of flanges that have raised face and back ups. Made from quality mill plates, these flanges have high weldability & hardenability. Our range of plate flanges can be availed in different dimensional specifications depending upon the requirements and their applications.

Advantagesstainless steel plate flanges are produced from quality mill plate. Mill plate produced to the astm a240 and asme sa240 standards is virtually free of voids, non-metallic inclusions and other defects. The inherent corrosion resistance of stainless steel is enhanced by the superior grain structure offered by plate products over forged or cast products.
as companies begin to look at life-cycle costing models, in almost every case, the slightly higher initial cost of stainless steel plate flanges is more than offset by the extended service life and the reduction of the normal maintenance costs.
stainless steel plate flanges are a widely accepted alternative to cast or forged flanges in low pressure applications.

Our Reducing Flanges are designed in compliance with international quality standards. Available in all types and pressures, these flanges are widely used for pipe-to-pipe connections. The reducing flange includes a flange with one specified diameter having a bore of a different and smaller diameter. Except for the bore and hub dimensions, the reducing flange will have dimensions of the larger pipe size. To increase the size of the flange, these are used at the outlet side of the expansion joint. Also provides Steel Reducing Flanges and Stainless Steel Reducing Flanges. It is the most economical method to make a transition in size.

Stainless Steel 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.

Material Used:Common materials used are as follows :

• Stainless steel
• Brass
• Steel
• Alloy Steel
• Aluminum
• Plastics
• Titanium
• Monels
• Carbon steel
• Alloy titanium etc.

KeyFeatures :Some important features are as follows :

• One size fits all pipe schedules.
• Fabricators can more easily cut pipe to length for slip-on flanges.
• The smaller thickness of this flange allows for easier alignment of bolting holes.
• They are generally not preferred for high pressure temperature environments.

Advantages of slip on flanges :

• Low cost installation
• Less time needed to spent on ensuring the accuracy of the cut pipe
• They are somewhat easier to align
• The slip-on flanges have low hub because the pipe slips into the flange before welding
• The flange is welded both inside and outside to provide sufficient strength
• They prevent leakage

Stainless Steel Socket welding 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 weld 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 weld flange as would be required with slip-on flanges. For this reason, the internally welded flange is popular in chemical process piping.

Materials used:

• Alloy steel
• Carbon steel
• Stainless steel
• Cast iron
• Rubber
• PVC
• Thermoplastics
• Aluminum
• Brass
• Bronze etc.

Key Features:The recess on the inside diameter of the socket weld flange allows for a good fit of the pipe allowing for a smooth flow of liquid.
Socket welding 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 welds.

Stainless Steel Threaded flanges are widely demanded as pipe flanges i.e called as threaded pipe flanges used in different industrial applications. They are the special type of pipe flanges which can be attached to the pipe without welding. Threaded flanges are threaded in the bore which match an external thread on the pipe. These threads are tapered in order to create a seal between the threaded flange and the pipe as the tapers approach the same diameter. Sometimes a seal weld is also used together with the threaded connection. They are available in various sizes and materials.

Materials used :

• Stainless Steel
• Alloy Steel
• Carbon Steel
• Cast Iron
• Steel
• Aluminum
• Brass
• Bronze
• Monel
• PVC
• Thermoplastic etc.

Uses of threaded flanges :

• Threaded flanges can be fitted to pipes of various sizes without welding and this is one chief benefit for which these flanges are highly demanded.
• They can be used in extremely high pressure applications, particularly at or near atmospheric temperature, where the necessary post weld heat treatment is not possible.
• They are ideal for small diameter piping applications.
• They are economical and time saving devices.
• These threaded flanges are normally designed for non-cyclic applications.
• The flanges are suitable to be used in applications where welding is hazardous.
• They can be used in highly explosive areas.
