ASTM A312 TP316 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.

Hastelloy C-276 is the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.

Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media

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.

Therefore, the fixation of the slip-on flanges is easier. However, the strength of the slip-on flanges is two-third of the weld necked flanges, under internal stresses due to flow. Another disadvantage of the slip-on flanges is that it¡¯s impossible to fix a flange to the elbow or fix a flange to the tee because the end surface of the slip-on fittings is not straight. The third flange group is the socket weld flanges. These flanges are utilized for small pipes that must yield high pressures. The strength of the socket weld flanges against internal stresses is equal to slip-on flanges.

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.

Typical corrosion applications include titanium dioxide production (chloride route), perchlorethylene syntheses, vinyl chloride monomer (VCM), and magnesium chloride.

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

Alloy 347 stainless steel plate exhibits good general corrosion resistance that is comparable to 304.

Alloy 600 is non-magnetic, has excellent mechanical properties and a combination of high strength and good workability and is readily weldable.

When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400.

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.

Prefabricated steel s take advantage of offsite prefabrication to improve the speed or erection and cost predictability of the solution.

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

AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.

HASTELLOY C276 has exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.

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

It has great resistance to stress-corrosion cracking and pitting. Hastelloy B-2? also features hydrochloric acid resistance at all concentrations and temperatures.

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.

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

Therefore the selected radius of the elbow can be very important. The other type of elbows is reducing elbows. In this type of elbows, the dimension of the center-line radius equals to the half of the nominal size of the larger end. Reducing elbows, again, maintain a 90¡ã flow change in the pipeline system. Moreover, a 180¡ãflow change can also be maintained by using a specific type of reducing elbow that is called ¡®return bends.

?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.

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

The alloy has good oxidation resistance and creep strength to 1500¡ãF (816¡ãC). It also possesses good low temperature toughness.

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.

Inconel 718 has become useful in a wide range of applications ranging from manufacturing operations to military equipment and the aerospace industry.

One of the distinguishing features of Inconel 718¡¯s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling.

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.

It is used for components that require exposure to sea water and high mechanical stress.

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site
