304 tees with elbow and reducers

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.

Inconel is a superalloy made of high concentrations of nickel, chromium and molybdenum. Inconel 625 is highly resistant to corrosive and oxidizing media in a variety of environments. These alloys have excellent ductility and excellent formability. They can be welded easily and are resistant to post-weld carburization or graining.

The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.

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.

In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. Furnace retort seals, fans and fixtures.

Resistance to chloride ion corrosion is one of the main factors that facilitate the use of incoloy grades in different industrial applications.

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.

This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content, alloy 400 is rapidly attacked by nitric acid and ammonia systems.

They are used for high temperature service, where resistance to oxidation and carburisation are required. For optimum stress rupture properties, or for pressure vessel service above 815¡ãC, Incoloy 800H or Incoloy 800HT should be used.

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

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.

Their Inconel surface becomes corrosion resistant due to the formation of patina. Incoloy material has a higher iron content and is less expensive than Inconel products. They are also resistant to corrosion from a variety of materials, including steam and acids. These materials are resistant to seawater, acid gas and saltwater 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.

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

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

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

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.

Superalloys have good oxidation and creep resistance and can be strengthened by methods such as precipitation hardening, solution hardening and work hardening. They can also function under high mechanical stress and high temperature and where high surface stability is required.

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.

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.

Hastelloy C-276 is a nickel-molybdenum-chromium-tungsten alloy with excellent general corrosion resistance and good machinability. The alloy should be considered for use in environments requiring resistance to thermally contaminated inorganic acids, organic and inorganic chloride-contaminated media, chlorine, formic and acetic acids, acetic acid, acetic anhydride, seawater and brine solutions.

Roller hearths and radiant tubes, in carbon nitriding processes especially.

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

Stainless steel grade 254 SMO? is a very high end austenitic stainless steel.

These specialist fabricators produce the system under the specified set of quality and accuracy to obtain proper fit at the site and to maintain the necessary technical properties defined by the client.

Reworking of Alloy K-500 is best done while the material is in the annealed or hot worked and quenched condition. However, age hardened materials can be finished to close tolerances and finish. Therefore, the recommended practice is to machine slightly oversize, age harden, and then finish to size.

Monel 400 is a nickel-copper alloy (about 67% Ni ¨C 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.

Incoloy 825 is a superalloy with molybdenum and copper added to Incoloy 800. This makes Alloy 825 superior to Alloy 800 in terms of corrosion resistance.

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.
