stainless steel pipes 304 304L with flanges

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.

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

Process equipment used in the production of chlorinated and fluorinated hydrocarbons.

Pipe spools are pre-fabricated to reduce field installation costs and provide higher quality in the products. They are generally flanged to obtain the connection to other spools. The spool fabrication is normally performed by special companies having the required infrastructure.

In nuclear reactors uses are for such components as control rod inlet stub tubes, reactor vessel components and seals, steam dryers and d separators in boiling water reactors.

It cannot be hardened by heat treatment;?however?the material will harden due to cold working.

Hastelloy B2 is a nickel-molybdenum alloy especially suitable for handling equipment that reduces chemical environments. Such as applications in chemical processing industries involving sulfuric acid, phosphoric acid, hydrochloric acid and acetic acid.

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.

Pipe Spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in fabrication shops.

Pipe spools are produced by the usage of raw pipes and pipe fittings. The cutting process of the raw pipes is done with prespecified sizes that are suitable for the pipe fittings and other components.

Steel Pipe Spools are also referred as prefabricated components of a piping system such as pipes, flanges and pipe fittings, and they are mounted during the development before sending them to the manufacture.

It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.

The following procedure after the marking is the cutting step. The way of cutting differs for various materials. Thus, for carbon steels, the flame cutting method is utilized. Moreover, stainless steel components can be cut using a plasma arc cutting machine. If the plasma arc cutter is used some certain conditions must be maintained.

MONEL 400 solid solution alloy can be hardened by cold work, but can be hot worked or cold worked, then annealed into complex structures and welded using an appropriate welding process.

Nickel- and cobalt-based corrosion-, temperature- and wear-resistant alloys, such as Hastelloy B2, are classified as moderate to difficult when machined, but it should be emphasized that these alloys can be produced at satisfactory speeds using conventional production methods processing. During machining, these alloys harden rapidly, generate high heat during cutting, weld to the cutting tool surface, and provide high resistance to metal removal due to their high shear strength.

Pipe spool systems are mostly used in power plants and petroleum refineries which requiring intensive piping. These systems include carriage and transport of fluid and gas and these transportation systems need lots of connection parts. In these systems, there is no place for mistakes.

This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts the austenitic structure.

In most instances, the carbon content of the plate enables dual certification.

In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. Furnace retort seals, fans and fixtures.

Pipe spools are the pre-build parts of a piping system. Pipes, flanges, and fittings are called pipe spools and they are produced before they are used in the piping system.

It can be easily welded and processed by standard shop fabrication practices.

INCONEL 718 alloy was primarily chosen by design engineers for its high strength in extreme temperature conditions at both ends of the spectrum. It can be used from low temperatures all the way up to 1300¡ãF/704¡ãC. It exhibits extremely high yield, tensile and creep rupture properties across the entire range. It also exhibits excellent tensile and impact strength.

Hastelloy B2 prevents the formation of grain boundary carbide precipitates in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat affected weld zone reduces the precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.

Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900¡ãF. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.

Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium.

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.

Hastelloy is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

Elbows are generally used for a change in the direction of the flow. Common elbow systems can change the angle of the flow at 180¡ã, 90¡ã or 45¡ã. The 180¡ã elbow system is also called a ¡®return bend¡¯. The elbow systems can be classified into two groups which are butt weld elbows and reducing elbows. Butt-welded elbows are the most common and desired components.

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.
