ASTM A312 304L Stainless Steel Seamless Pipe with Flange

304 Piping Spools are made of 304 Stainless Steel, a common and popular material in many industrial applications that require resistance to corrosion and oxidation. These S30400 Piping Spools are prefabricated using specialized machinery and processes, which ensure that they are highly accurate and reliable.

Inconel 718 consists primarily of nickel (52%). Alloying elements include iron (19%), chromium (18%), niobium + tantalum (5%), molybdenum (3%), titanium (0.9%), aluminum (0.5%), in addition to other trace elements such as Baron, Cobalt, Copper, Manganese and Silicon.

As a corrosion resistant alloy, Monel 400 can withstand high temperature steam environments and fast flowing brackish/seawater, while maintaining excellent resistance to stress corrosion cracking in most fresh waters.

Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B2 is resistant to pure sulfuric acid and many non-oxidizing acids. This alloy should not be used in the presence of oxidative contaminants in oxidizing or reducing media. Premature failure may occur if Alloy B2 is used in the presence of iron or copper in systems containing hydrochloric acid.

Alloy 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.

The tees are also used for the change of the flow angle and distribution of the flowing matter either into one or more channels. Tees can be divided into two main groups which are the butt welded tees and the socket welded tees. The butt welded tees are utilized to perform a perpendicular distribution of the flow. They make 90¡ã branches with the connection of the pipeline and distribute the coming matter from the mainline.

C276 is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Alloy 347 stainless steel plate cannot be hardened by heat treatment, only by cold working.

Prefabricated steel s as the name itself sounds, is made of pre engineered steel. Fabrication is done in controlled environment inside the factory and then sent to client location for assembly.

The corrosion resistance of Monel K-500 is basically the same as Alloy 400, except that in the age hardened condition, Alloy K-500 has a greater tendency to stress corrosion cracking in certain environments. Monel K-500 has been found to be resistant to sour gas environments.

This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as Flue gas desulfurization and Chemical environments.

MONEL K-500 alloy has corrosion resistance comparable to 400, but has higher mechanical strength and hardness. Has good thermal corrosion resistance and long-term tissue stability. It is mainly used in the manufacture of turbine blades and gas turbine blades with a working temperature below 750¡ãC on aero-engines, and in the manufacture of fasteners and springs on ships; pumps and valve parts on chemical equipment, and scraping on paper-making equipment. Blades etc.

The durability of steel is one of the best advantages of the pipeline systems. It is strong and it can withstand the pressures, temperatures, heavy shocks, and vibrations. It also has unique flexibility which provides an easy extension.

Alloy 600 is used in chemical and food processing, heat treating, phenol condensers, soap manufacture, vegetable and fatty acid vessels and many more.

However, their fatigue strength is higher than the slip-on flanges. A major problem of the socket weld flanges is the corrosion risk. A gap between the flange and fitting or pipe must be maintained before the welding. Corrosive fluids or humidity can locate in these shelters. Thus, this solid-liquid interface may cause corrosion on the body.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

The socket welded tees are manufactured due to the ASTM ASME B16.11 standards. These standards optimize and decide the proper pressure and temperature ratings, radiuses and required material for the production of the tees. Furthermore, the B16.11 standards are only allowable for carbon and alloy steels. The socket welded tees can be produced into three pressure categories which are; Class 3000, Class 6000 and Class 9000.

904L grade stainless steel is unlike any other steel. Due to its extra amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids.

For certain applications, grade 254 SMO has been reported to be a cost-effective substitute for high nickel and titanium alloys.

Hastelloy C-276 is easily fabricated by welding, using methods similar to those used for nickel-based alloys.

Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 ¨C 0.10) version of the alloy.

At elevated temperatures the annealed and solution annealed alloy shows good resistance to scaling and has high strength.

Alloy 254 SMO is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content.

The addition of copper to this grade gives it better corrosion resistance than conventional chromium-nickel stainless steels, especially against sulfuric, phosphoric and acetic acids. However, the use of hydrochloric acid is limited.

625 has outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.

They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

Incoloy 825 is a superalloy with molybdenum and copper added to Incoloy 800. This makes Alloy 825 superior to Alloy 800 in terms of corrosion resistance.

Alloy 800 has moderate corrosion resistance to many aqueous media and is resistant to stress corrosion cracking due to its nickel content. At high temperatures, it has resistance to oxidation, carburization and vulcanization as well as fracture and creep strength.

Just as the name ¡°Pre-engineered¡± suggests, these s are engineered at a factory and are assembled at site.

316L, however, is a better choice for a project that requires a lot of welding because 316 is more susceptible to weld decay than 316L (corrosion within the weld).
