Blind Flange
Solid blank flanges for pipeline isolation, shutdown and maintenance, available in carbon steel, stainless steel and alloy steel per international standards.
Alloy steel flanges are chromium‑molybdenum forged components, designed for extreme high temperature and high pressure industrial piping systems.
Alloy steel flanges are high‑performance forged fittings manufactured from chromium‑molybdenum (Cr‑Mo) steel. By adding alloying elements such as chromium, molybdenum and vanadium, they achieve outstanding mechanical strength, excellent resistance to oxidation and creep at elevated temperatures.
Our alloy steel flanges comply with ASTM A182 and global standards, covering grades from low‑alloy F1 to high‑alloy F91. They are the first choice for critical high‑temperature, high‑pressure pipelines in power, refining and petrochemical industries.
Each grade is formulated for specific temperature, pressure and corrosion environments:
| Grade | Composition | Max Temp | Typical Application |
|---|---|---|---|
| ASTM A182 F1 | Low‑alloy Cr‑Mo | 450°C | Moderate high‑pressure steam |
| ASTM A182 F5 | 5Cr‑0.5Mo | 550°C | Refinery, high‑sulfur crude, H₂ service |
| ASTM A182 F11 | 1.25Cr‑0.5Mo | 550°C | Power plant auxiliary steam, heaters |
| ASTM A182 F22 | 2.25Cr‑1Mo | 600°C | Main steam, high‑temperature hydrogen |
| ASTM A182 F91 | 9Cr‑1Mo‑V‑Nb | 650°C | Ultra‑supercritical power plants |
Alloy steel flanges are a type of flange made from a combination of metals that are known for their strength, durability, and resistance to corrosion. They are commonly used in high-pressure and high-temperature applications, such as in the oil and gas, chemical, and petrochemical industries.
These flanges show excellent corrosion and oxidation resistance. They are widely used in water lines, oil, and gas, chemical plants, food production systems, etc.
Offered range is stringently tested on various parameters of quality for ensuring flawlessness and defect free. These products are widely used in various industries and widely appreciated by clients for owning unmatchable characteristics. Offered range supplied in quality assured packaging material.
Alloy steel flanges are a crucial component in industrial piping systems, offering enhanced mechanical properties and resistance to various types of stress compared to carbon steel flanges. These flanges are used in applications that demand high strength, toughness, and corrosion resistance, particularly under extreme conditions such as high pressure and high temperature.
Alloy steel flanges are widely used across various industries due to their adaptability and reliability. Common applications include:
While alloy steel flanges are highly durable, regular inspections and maintenance are essential to ensure their continued performance. This includes checking for signs of corrosion, wear, and ensuring that all connections are secure.
Alloy steel flanges are a critical component in many industrial systems, offering unmatched strength, durability, and resistance to harsh conditions. Their versatility and reliability make them the preferred choice for demanding applications across various industries.
Natural, Nickel Plated, Electro Polished Plated or any coating as per customer specification.
Any kind of special die casting sand gravity die lost wax shell moulding castings and cast parts casting produced to user specifications. We can be more competitive than Chinese castings and cast parts made in China Taiwan Asia Korea as traditional Indian expertise in Brass castings and Brass casting is superior and Indian alloy Steel foundry / foundries are more competitive than other S.S. alloy Steel foundries.
Alloy Steel Flanges, Alloy flanges are corrosion resistant and have a wide variety of uses. We carry a variety of threaded flanges, weld neck flanges and slip- on flanges and, of course, we can can custom build steel flanges to your specifications.
Our manufacturing arena is well known in the market that comprises of various flanges one of which is Alloy Steel flanges. They are available in variety such as weld neck, Deck flange, lap joint etc. They are made of steel and other metals thereby forming an alloy. These flanges have undergone stringent quality check and have been certified by national authorities.
The ANSI B16.5 Alloy Steel Slip On Flange can be slid on any pipe and welded in exact positions. They are the most popular and cost-effective flanges in the market. The High Alloy Steel Slip on Flange is made up of high qualities of alloyed material. These flanges contain at least 12% of chromium and are known for their hardenability. Low Alloy Steel Weld Neck Flange is designed with good mechanical properties. These flanges have a protruding hub, which provides support to pipes in high-pressure applications. The 4130 Chromoly Threaded Flange is used as companion flanges in piping systems. Our experienced workers make use of the latest technology and best raw materials whilst producing the ASME SA 182 AS Pipe Flange and our other products.
The Chromoly 4130 Reducing Flange is used to combine pipes of different shapes and sizes. They are designed with a bore having a specified diameter. Alloy Steel Socket Weld Flanges are used in higher-pressure systems having small pipes. They are fitted after applying a fillet weld. The Chrome AS Blind Flange is designed with a boring center. They are used in sealing the nozzles or openings in piping systems. They can be welded permanently or bolted as per requirement. The Alloy Steel Blind Flanges along with, our other products can be easily customized as per your needs in different shapes and sizes. Contact us to know more.
Alloy steel flanges also ranged with slip on flange, weld neck flange, blind flange, socket weld flange and threaded pipe flange.
Steel flanges must be packed with seaworthy packing method then delivery to customers, usually the packing way include wooden box, wooden pallet, iron & steel cage, iron & steel pallet etc.
Flange markings are governed by ANSI ASME codes. Flange marking includes;
ASME B16.5 and B16.47 standards cover permissible tolerances for inspection.
Because of the normal wooden boxes or wooden pallets have to do fumigation treatment, we usually use plywood pallet or plywood case or box to pack steel flanges without fumigation treatment.
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
