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.

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 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100).

Alloy K500 is refined by Electroslag Refining (ESR), ensuring the cleanest and highest quality material. This increased alloy purity limits the potential for hard non-metallic inclusions that can increase machining difficulty, machining time and ultimately lead to part failure. It also has low permeability and is non-magnetic at temperatures as low as -150¡ãF (-101¡ãC).

Pipe spool fabrication is very important because the construction of the ship and other marine industries require intensive piping. Pipe spools create great advantages because they reduce the limitations of space on site.

Monel 400 is used in process vessels, heat exchanger piping, and gasoline and potable water storage tanks in the marine sector. The non-sparking properties of this alloy make it suitable for high-risk situations in the explosives industry, rockets and pulp and paper industries.

The Alloy 800 series (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that provide high temperature strength and resistance to oxidation, carburization and other types of high temperature corrosion. Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800HT (UNS N08811) have the same nickel, chromium and iron content, except for the total titanium and aluminium content (0.85 to 1.2%) to ensure optimum high temperature performance.

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

It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.

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

Alloy 625 has excellent fatigue strength and stress corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability and is often used to weld AL-6XN. This alloy is resistant to a variety of severe corrosive environments, especially pitting and crevice corrosion.

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.

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

It cannot be hardened by heat treatment;?however?the material will harden due to cold working.

Pipe spool systems are mostly used in power plants and petroleum refineries which requiring intensive piping. These systems include carriage and transport of fluid and gas and these transportation systems need lots of connection parts. In these systems, there is no place for mistakes.

Reactor vessels and heat exchanger tubing used in the production of vinyl chloride.

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

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 sluggish age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling.

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

It is known to possess excellent workability as well.

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

304 stainless steel does have one weakness: it is susceptible to corrosion from chloride solutions or saline environments such as the coast.

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.

Little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to 550C in these media, this alloy has been shown to be one of the most resistant of the common alloys.

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

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.

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

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.

The high amounts of nickel and chromium in austenitic stainless steels provide excellent mechanical properties, as well as excellent corrosion resistance.
