ASTM A790 2507 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.

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

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.

625 has almost complete freedom from chloride induced stress corrosion cracking.

?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.

HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

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.

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.

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

The higher molybdenum content of Alloy 317L assures superior general and localized corrosion resistance in most media when compared with 304/304L and 316/316L stainless steels.

A fit-up and welding process must be applied after the edge finish of the parts. Therefore, for stainless steel and carbon steel pipe spools, parts can be located onto steel bases or wooden bases. Furthermore, any contact possibility between carbon steel and stainless steel must be minimized.

Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted together (i.e. temporarily connected). The resulting sub-assembly (part of the final pipe spool) continues with welding operations (i.e. permanent connected) before it comes back to the fitting table and gets fitted with other spool 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.

One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.?

The versatility of INCONEL 600 alloy allows it to be used in a variety of applications involving temperatures ranging from cryogenic temperatures to over 2000¡ãF (1095¡ãC).

This alloy is widely used in the chemical industry for its strength and corrosion resistance. Applications include heaters, stills, bubble columns, and condensers for fatty acid processing; evaporator tubes, tube sheets, and sheeting trays for the manufacture of sodium sulfide; and equipment for processing abietic acid in pulp production.

MONEL K500 is a age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance.

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

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

UNS S31254 is often referred to as a ¡°6% Moly¡± grade due to the molybdenum content.

This nickel alloy is used from cryogenic temperatures up to long term service at 1200¡ã F.

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.

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

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.

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.

A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.

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 alloy is capable of remaining stable and maintaining its austenitic structure. Incoloy 800 is primarily used in applications with temperatures up to 1100¡ã F, where alloys 800H and 800HT are normally used in temperatures above 1100¡ã F where resistance to creep and rupture is required.

As a beginning of the manufacturing, all components must be marked in order to increase the monitorability of the materials. The marking work can be implemented due to the respective number of components. Moreover, all dimensions of the pipe spools must be marked on to themselves. The traces on the components must not contaminate the material otherwise traces can react with the material and this may cause deleterious problems.

Alloy X is known for its excellent high temperature strength and can withstand temperatures up to 2200¡ãF. The alloy can also be easily fabricated by manual and automated methods with forming and welding properties. In addition, Hastelloy X is resistant to corrosion, heat and oxidation and can withstand reducing or neutral atmospheres and oxidation.
