ASTM A312 TP316 Stainless Steel Seamless Pipe with Flange

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

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

Alloy 904L outperforms other austenitic stainless steels due to the higher degree of alloying of nickel and molybdenum.

The number of welds on a spool must be kept in a minimum count. The dimension of the spacing between circumferential welds and the center lines must not be larger than the four times the wall thickness of the pipe or fitting. After the main welds, tacks welds must be done precisely. All welds in the spools must be implemented according to proper Welding Procedure Specification (WPS). After the welding process is done, quality control of the components is performed by the specialists.

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.

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.

When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.

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

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

This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as Flue gas desulfurization and Chemical environments.

The whole butt weld system must be produced with the beveled ends. The 90¡ã butt welded elbows are produced to make a perpendicular angle in every direction. They can be supplied as short and long radius ones. The desired fixation and the correct centering between the components can be maintained via using a truly calculated radius.

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

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

Production of caustic alkalis particularly in the presence of sulfur compounds.

The alloy’s properties make it an excellent choice for sea-water applications, including freedom from local attack (pitting and crevice corrosion), high corrosion-fatigue strength, high tensile strength, and resistance to chloride-ion stress-corrosion cracking.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

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

Prefabrication is the practice of assembling components of a structure in a workshop or other assembly facility before transporting to site for erection.

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.

Alloy 400/Monel 400 comes directly from refined ore bodies in Canada, and with a copper content of approximately 30 wt%, it provides a lower cost alternative to commercially pure nickel, but still retains a very similar characteristics.

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.

We manufacture piping products as well. When customers need different elements be fitted together before installation, the application of fabricated elements together is called the piping spool applications. There are Stainless Steel Pipe Spools products as well other material made spools in used.

It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 ¨C 1500¡ãF (427 ¨C 816¡ãC).?

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.

Alloy C-276 is also defined as Alloy C276, Inconel C 276 or Hastelloy C, which is a superalloy with a perfect combination of molybdenum, nickel and chromium. Tungsten is added, which is designed to provide excellent corrosion resistance even in harsh environments.

The pipeline system must be produced and mounted away from the facility site. These complex facilities use pipe spools with different measurements and various components. Pipe spools are the prefabricated segments that include pipes, flanges, and fittings. Pipe fittings are the components that connect the complex pipe network. Moreover, pipe fittings change the piping systems¡¯ either sizes or dimensions. There are various types of fitting components but they can be briefly divided into three groups which are elbows tees and 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.

Inconel 625 alloy is widely used in chemical processing, pollution control, evaporators, nuclear reactors, marine industry and more.

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.
