Threaded Flanges
Our range of Threaded Flanges finds applications in various industries. These are special type of pipe flanges that can be attached to the pipe without welding. The 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.
Our range of Flanges are made using high grade material, such as Stainless Steel, Alloy Steel, Carbon Steel, Cast Iron, Steel, Aluminum, Brass, Bronze, Monel, PVC and Thermoplastic.
Uses of threaded flanges:
readed 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.

Plate Blank Flanges
Our range of Plate Blank Flanges is used for sealing the ends of a pipeline or any or any other connection are manufactured by us. These have a kind of round plate without any center hold but with all proper bolt holes. Our range is offered with plates with a raised face and back ups for easy installation. The use of superior quality mill plates gives these plates high weld ability & hardens ability. Our Flanges provide easy access to the line.
Features
Durable
Dimensionally accurate
Have high tensile strength
Corrosion resistance
Easy to install
Slip-On Flanges
Slip-on flanges are designed to slide over the outside diameter of the pipe to which it will be welded as Slip-on flanges are easy to use in fabricated. These flanges are attached to the pipe by fillet welding at the hub and at the end of the pipe inside the flange. These high quality Slip on Flanges are the right choice for lower pressure applications such as Oil Industry, Gas Industry, Filtration Industry, Refrigeration Industry, Refining Industry, Petrochemical Industry, Offshore Industry etc.
The flange is slipped over the pipe and then welded both inside and outside to provide sufficient Strength and prevent leakage. This flange is used in preference to weld necks by many users because of its lower cost and the fact that less accuracy is required when cutting pipe to length.
Their calculated strength under internal pressure is approximately two-thirds that of welding neck flanges, and their life under fatigue is about one-third that of the latter. For these reasons, slip-on flanges are limited to sizes ½" to 2 ½" in the 1500 lb standard and are not shown in the 2500lb standard.
Material Used
Stainless steel
Brass
Steel
Alloy Steel
Aluminum
Titanium
Monel
Carbon steel
Features:
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
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

Plate Flanges
We have been offering a wide range of Plate Flanges to our clients. These are special types of flanges that have raised face and back ups, which are made from quality mill plates. Our flanges have high weld ability & harden ability and are available in different dimensional specifications depending upon the requirements and their applications.
Advantages
Stainless 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//c// 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.
