Carbon steel flanges manufacturer in India
CS flanges are widely manufactured in India which are applicable in pipe-line units for various industrial sectors. Carbon steel flanges are basically made up of carbon and steel alloy which provides properties such as resistance to corrosion, excellent durability, and finishing in goods. The available content of carbon range is about 1% to 2.1% in weight in the CS flanges and are useful to connect valves, pumps and pipes for the piping system.
Flanges are components in pipe systems that hold pipes together with modified faces, collars or processes. As a carbon steel flanges manufacturer in India we produce flanges of different types to be used in different applications. The Carbon Steel Flanges have high wear and tear resistance. They have less corrosion resistance compared to most stainless steels and have less strength compared to some special alloy material, but they are of high cost efficiency. There are different types of flanges used in different applications. Our Carbon Steel Blind Flange is used to close a pipe line in a system. The blind flange has a flat end with which it closes the pipe.
Contact Dinesh industries, a well established carbon steel flanges manufacturer in India.

Supplier of low temperature & normalized carbon steel flanges in different types including blind, slip on, orifice, weld neck, socket weld flange in FF/ RF faces
The carbon steel flange flat face is flat surface completely where used gasket gets packed in as bolting circle face to both connected flat surfaces of 2 flanges in pipeline.
FF faces are meant to prevent the bending movement that is put on flanges as the bolts are torqued. FF are widely used in as low temperature carbon steel flanges with low pressure system of water treatment facilities
Carbon steel raised face flange are raised surface above the bolting circle where the gasket are supposed to be placed in the joining sections. RF faces are meant to concentrate the contact pressure on the gasket area, results in increased strength of the seal and appropriate for both high and low temperature and pressure so have vast uses in oil and gas industry.
There are CS Slip On Flange types which allow pipes to slip through them so the connection could be made in the desired locations. Most flanges are welded together with the pipe for maximum and permanent connectivity. The Carbon Steel Puddle Flange is used to connect two pipes and seal them tight by holding the ends of pipes inside the flange structure. We are leading Manufacturer of Low Temp Carbon Steel flanges. The Carbon Steel Weld Neck Flange has a welded neck that increases the grip with the pipes and welding surface. Our Low Carbon Steel Forged Flange has comparatively higher corrosion resistance and strength but low wear and tear resistance. We supply carbon steel flanges in Singapore, UAE & Malaysia at very competitive price. Please contact us for any query like dimensions, ready stock sizes and latest price list.

Type of carbon steel flanges in use are as below mentioned:
- Weld neck carbon steel flanges are having large neck and their connecting end is welded to bottom, wherein internal diameter is similar to the flange and used in extreme conditions.
- Carbon steel slip on flange is designed to accept pipe into the bore/centre of the flange for welding around outer diameter of the pipe and interior side of connection. Its also good in use in extreme conditions besides being inferior to neck flanges.
- Carbon steel blind flanges are used in covering the ends of the tube, valves or pipe lines of operating process. Its type of ASME fitting which makes it suitable to resist against extreme conditions of work.
- Threaded carbon steel flanges though do not have any welding feature but make easy quick assembly and useful for implementations within high temperature and pressure wherein male NPT threaded pipes are used.
- Carbon steel tongue and groove flange are standard small or large size type in which the inside diameters of the groove and tongue do not extend into the flange base, thus retaining the gasket on its inner and outer diameter.
- Killed carbon steel flanges are type of forged flange are destroyed in melting process, wherein due to addition of Manganese, Silicon, and Aluminium during the production of steel, deoxidation occurs.

Know the manufacturing process of carbon steel forged flanges and CS plate flange, wide selection of low temp carbon steel flanges in class 150-2500
Carbon steel forged flanges are manufactured using forging machines wherein steel bars are heated and shaped under high pressure and temperature.
It allows for flange dimension and shape customization, mostly applicable for high pressure, high temperature, critical applications of chemical, petrochemical, oil and gas industry.
Carbon steel plate flange are flat flanges made by cut and drilled according to flange dimension. The bolt holes are thin and lighter used in low pressure and non-critical applications like water supply, irrigation and HVAC systems. Forged carbon steel flanges are better than plate flange in aspect of corrosive properties, meanwhile plate flanges are less expensive than forged flanges.

Exporter & supplier of threaded, slip on & weld neck carbon steel flanges in India, view advantages and installation process
Carbon steel pipe flanges are mode of connecting for 2 particular pipe line joints section, an advantage of such flanges is that they are convenient for welding and processing with high strength. Such connections are affordable for future disconnecting, reconnecting and zero-clearance assembly for easier maintenance activities, tube and hose connection.
Carbon steel flange are installed via welding, screwing, or lapping and in installation of flange, initially flange is placed in the pipe end, welding ring is then welded in pipe end, welding sky further is used as the sealing surface and tighten the two flanges to connect the pipe fittings. Also, some safety concern and plant external as well as internal pipe line units are considered like shutdowns and change of flow directions and others are to be known before work proceeds.
