nickel alloy Hastelloy C276 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.

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

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.

Inconel 718 is a precipitation hardenable nickel-chromium alloy with high creep rupture strength at elevated temperatures around 700oC (1290oF). It is stronger than Inconel X-750 and has better mechanical properties at low temperatures than Nimonic 90 and Inconel X-750.

Thus, the pipeline system must be designed and produced in a way that can handle the induced stresses during the transportation of liquid or gaseous substances. Some facilities (power plants, petroleum refineries, etc.) require long and complicated pipeline systems. Moreover, these types of facilities handle problems because of the limited working space.

Flanges are the components that work as a connector between main pipes, valves or pumps. The most prominent advantage of the flange usage easy the ease of cleaning and inspection of the area connected by the flanges. Flanges are usually produced by utilizing welding or screwing methods. Flange systems make a joint between different components.

Under alternating oxidizing and reducing conditions the alloy may suffer from selectiveo xidation.

The strength of this nickel steel alloy is maintained to 1200¡ã F but stays ductile and tough down to temperatures of 400¡ã F. Its melting range is 2400-2460¡ã F.

The butt welded tees can maintain a straight flow or reducing flow which depends on the ordered pipeline system. The reducing branches (reducing tees) make a perpendicular connection with the mainline. The radiuses of the tees are usually smaller than the main flow line. The radiuses of the straight tees are produced in a way that has similar radiuses with the main flow line.

For service requiring optimum creep and rupture properties, Incoloy 800H or 800 HT are used. The high contents of nickel and chromium in the alloys also give good corrosion resistance.

304 stainless steel does have one weakness: it is susceptible to corrosion from chloride solutions or saline environments such as the coast.

Resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.

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.

Blind flanges are the final division of the flange classification. They are used as end-closers for the pipes valves or pumps. Since blind flanges are used as obstacles against the fluid flow, they are the highest stressed parts of the flange systems.

Inconel 625 material has excellent strength and hardness. They have a minimum tensile strength of 120Ksi and a minimum yield strength of 60ksi. In addition to that, they can easily be stretched up to 30% and still have excellent workability.

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

The pipe spools are usually applied in concrete structures to make sure the necessary fittings are in place before pouring concrete into the construction.

Monel K-500 combines the excellent corrosion resistance of Monel 400 with the added benefits of higher strength and hardness. Performance can be improved by adding aluminum and titanium to the nickel-copper matrix and by heating under controlled conditions to precipitate submicroscopic particles of Ni 3 (Ti, Al) throughout the matrix.

Grade 304 stainless steel is generally considered the most common austenitic stainless steel.

Some typical applications for Inconel 625 include chemical processing, aerospace and marine engineering, pollution control equipment and nuclear reactors.

The joint is created by bolting two flanges to each other and sealing them by using various gaskets. Flanges are usually made of aluminum, bronze, brass or carbon steel. The most preferred material for general flange applications is the forged carbon steel. Moreover, flanges can be layered internally with different types of linings. Usually, flange material is selected as the same material with the pipe material. This material selection is conducted in order to prevent possible galvanic corrosion risks. The proper material selection for flanges is decided according to ASTM A-182 standards.

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

This Stainless Steel Pipe Spooling are often flanged to facilitate the connection to other spools and also mostly preferred in various industrial applications such as power plants and petroleum refineries require intensive piping.

Alloy 317L can be easily welded and processed by standard shop fabrication practices.?

Little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to 550C in these media, this alloy has been shown to be one of the most resistant of the common alloys.

It can be used in reducing chemical environments and chemical processing industry.

Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of greater strength and hardness.

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.

?The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.

They generally easily corrode because of the elements they exposure; water and natural electrolytes. Acceptable protective monitoring must be done when applying pipe spool systems.
