It is available in materials of ASTM A 182, and ASTM A 105. The flanges are available in various grades like ASME B16 47 ¡®A¡¯ Series, and ¡®B¡¯ Series to suit the needs of the clients and the industry.

In applications where higher working pressures are a prerequisite, the use of seamless pipes is justified. Although stronger than welded pipe, the cost is much higher. In addition, in welded products, there is a greater risk of intergranular corrosion in the heat-affected weld zone. The obvious difference between alloy steel welded pipe and seamless product is the transverse seam along the length of the pipe

ASTM A182 F5 flanges are a method of connecting pipes, valves, pumps, and other equipment to form a piping system. It also facilitates cleaning, inspection or modification.

The weld neck flange comprises of a round fitting that extends beyond the rim of the circumference. These flanges, typically manufactured from forging, are actually welded to pipes.

ASTM 182 is use in pressure systems, Included are flanges, fittings and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications. 182 F5 Cl2 Alloy Steel Flanges are well suited to not only high temperature but also high pressure or a combination of both these applications.

Alloy Steel F5 Flanges are square-shaped and are instrumental in interfacing pipes of nominal bore size without welding and are reasonable for high pressure hydraulic frameworks. ASTM A182 F5 Lap Joint Flanges go by a range of names, including back up flange, loose hubbed flange, loose ring flange and van stone flange. ASTM A182 Gr F5 Blind Flanges are commonly used in petrochemical, pipe engineering, public services and water works.

INCONEL? alloy 718 (UNS N07718/W.Nr. 2.4668) is a high-strength, corrosion-resistant nickel chromium material used at -423¡ã to 1300¡ãF. Inconel alloys are resistant to oxidation and have the ability to maintain its structural integrity in high temperature atmospheres.

The alloy has great mechanical properties at subzero temperatures.For catering to the needs of our customers better, it is essential that we manufacture Monel Pipe Fittings in different types, with each one serving some specific purpose.

At elevated temperatures, conventional steels, unlike ASTM A 335 P91 pipes, begin to lose their microstructural form, leading to failure. A burst or crack in the pipe is a visible fault. But since SA 335 P91 chrome-plated welded pipe is well suited to sustain itself at high temperatures, failure rates are extremely low.

ASTM A193 Grade B7 is a standard material specification for chromium-molybdenum alloy steel fasteners for use in high tensile, high temperature and special purpose applications.

ASTM A320 Grade L7M bolts and studs are also made from quenched and tempered alloy steel.

All chrome molybdenum steel sheets are sedated and heat treated in accordance with ASTM A387, which also specifies minimum and maximum levels of the following elements in steel: Chemicals of Carbon, Manganese, Phosphorus, Sulfur, Silicon, Chromium, Molybdenum, Nickel, Vanadium requirements, columbium, boron, nitrogen, aluminum, titanium and zirconium. A387 boards must undergo product, chemical and tensile testing (documented in the MTC or material test certificate) – must meet specific requirements for tensile strength, yield strength and elongation.

The A182 F9 Alloy Steel Blind Flanges are used to close a connection opposed to all other flanges which extend the pipeline. Alloy Steel ASTM A182 F9 Flanges is connected to the pipe by welding the pipe to the neck of the pipe flange. However, the inside diameter of ASTM A182 F9 Alloy Steel Flanges is being designed to match the inner diameter of the pipe.

This ASTM A182 alloy steel flange has a smaller thickness for easier placement of bolt holes. These ASTM A182 F12 alloy steel pipe flanges are suitable for high temperature and high pressure environments.

SA 182 Socket Weld Flanges are joined by inserting the pipe into the socket end and applying a fillet weld around the top. This allows for better flow of fluid or gas inside the pipe and smooth holes.

A335 P91 material, we use ASTM A335 Gr P91 Welded Pipe
Heat treatment method to standardize the strength of the material. 9% chromium and 1% molybdenum make the pipe strong and corrosion resistant. The material is resistant to wear and high temperature creep. ASTM A335 P91 pipe does not deteriorate, reduces thickness, and has higher creep strength. Pipeline applications are primarily used in power generation, petrochemical, heater and reheat liners, boilers, and petroleum services.

ASTM A182 F11 class 1 Flange is the method of connecting two pipes, pumps and valves. This consists of chromium molybdenum based alloy steel grade.

Among alloy steel grades, when metals like Nickel, Chromium and Molybdenum along with other alloying element content consist of less than 10.5% of the total alloy percentage, they are defined as low alloy steels.Generally, most low alloy steel flanges possess a precise chemical composition.

ASTM A335 Grade P11 is also commonly known as ASME SA335 Grade P11 Pipes, it is a seamless ferritic alloy-steel pipe that mainly has high-temperature applications. The UNS designation for this grade P11 is K11597.

A335 pipe is highly resistant to rupture at high temperature and pressure. Chromium molybdenum tubes with resistance to hydrogen cracking and sulfide stress corrosion cracking are superior to carbon tubes.
