nickel alloy Hastelloy C22 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.

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.

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.

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

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

The cylindrical bulge eases the use of flange in extreme conditions such as; elevated temperatures or high pressurized atmospheres. These flanges are welded to pipes or fittings by using butt-welding which enables a total fixation of the body. Slip-on flanges are also very common in use because of their low cost. They do not require excessive surface finishing as weld necked flanges.

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.

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

In today¡¯s world, pipelines are very common for almost every application that transports any liquid or gaseous substance. These liquid or gaseous substances flow in the pipe system with different pressures and temperatures. Therefore, pipeline systems are suffered from excess stresses that are produced by pressure and temperature.

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.

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

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.

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.

Hastelloy B3’s distinguishing characteristic is its ability to maintain good ductility while transient exposure to intermediate temperatures.

316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”

It has high resistance to oxidation at elevated temperatures up to 1050C.

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

Hastelloy C276 is known for its excellent corrosion resistance in a variety of corrosive media. It includes chloride ions, sulfur compounds, etc. In addition, this alloy has excellent resistance to crevice corrosion, pitting corrosion and stress corrosion cracking. It helps resist the corrosive effects of wet chlorine, chlorine dioxide and hypochlorite. This product is ideal for seawater applications.

This nickel steel alloy has good resistance to heat affected and knife-line zone attack. This alloy also bears the brunt of formic, sulfuric, phosphoric, acetic acids and various other non-oxidizing media.

With this advantage, all of the pipeline using industries has a great opportunity to increase their pipeline system efficiency and decrease their need for workforce and time.

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.

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.

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.

Pipelines for gathering sour gas have been built with solid (or clad) INCONEL? 625 alloy and used in seawater heat exchangers in refineries, power plants, and offshore topside services that often need this material.

316 can be annealed to resist weld decay.

Alloy 625 is generally supplied in the annealed condition, to provide utmost stability during fabrication and subsequent service.

HastelloyB2 is a nickel-based wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. Therefore, it has strong resistance to stress corrosion cracking and pitting corrosion. It is also resistant to hydrogen chloride, sulfuric acid, acetic acid and phosphoric acid. Hastelloy B-2 is a grade of Hastelloy?, a nickel-molybdenum alloy. There are many different grades of Hastelloy?, including B-2. Hastelloy? grades are optimized for specific applications. molybdenum

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.
