304 stainless steel pipes with elbows

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.

Alloy 600 / Inconel 600 is a combination of nickel chromium and iron that provides the standard material for the chemical industry and the automotive engine, aero engine and airframe sectors. Controlled chemical composition is restricted for use in the nuclear industry to eliminate the risk of stress corrosion cracking in high-purity water containing chloride ions.

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 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.

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

Elbows are generally used for a change in the direction of the flow. Common elbow systems can change the angle of the flow at 180¡ã, 90¡ã or 45¡ã. The 180¡ã elbow system is also called a ¡®return bend¡¯. The elbow systems can be classified into two groups which are butt weld elbows and reducing elbows. Butt-welded elbows are the most common and desired components.

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

Inconel 718 is a precipitation hardenable nickel-chromium alloy with high creep rupture strength at elevated temperatures around 700oC (1290oF). It is stronger than Inconel X-750 and has better mechanical properties at low temperatures than Nimonic 90 and Inconel X-750.

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

The socket welded tees are manufactured due to the ASTM ASME B16.11 standards. These standards optimize and decide the proper pressure and temperature ratings, radiuses and required material for the production of the tees. Furthermore, the B16.11 standards are only allowable for carbon and alloy steels. The socket welded tees can be produced into three pressure categories which are; Class 3000, Class 6000 and Class 9000.

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.

INCONEL 718 alloy was primarily chosen by design engineers for its high strength in extreme temperature conditions at both ends of the spectrum. It can be used from low temperatures all the way up to 1300¡ãF/704¡ãC. It exhibits extremely high yield, tensile and creep rupture properties across the entire range. It also exhibits excellent tensile and impact strength.

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

These connections are embedded inside concrete walls before the pouring of concrete. This system must be aligned properly before concrete pouring because it needs to withstand the weight and force of the structure.

Inconel 625 material has excellent strength and hardness. They have a minimum tensile strength of 120Ksi and a minimum yield strength of 60ksi. In addition to that, they can easily be stretched up to 30% and still have excellent workability.

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.

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

Hastelloy B2 prevents the formation of grain boundary carbide precipitates in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat affected weld zone reduces the precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

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.

Overcoming the impact of downtime caused by corrosion, stress and extreme temperatures, and the cost impact of failure rates and safety has driven the industry to look for materials like Monel 400, which provide increased reliability in harsh conditions.

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.

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.

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

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

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.

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.

Hastelloy C-276 resists the formation of grain boundary deposits in the weld heat affected zone, making it a candidate material for most chemical and petrochemical processing applications in the as-welded state. The alloy resists general and localized corrosion, including pitting, crevice corrosion and stress corrosion cracking.

The butt welded tees can maintain a straight flow or reducing flow which depends on the ordered pipeline system. The reducing branches (reducing tees) make a perpendicular connection with the mainline. The radiuses of the tees are usually smaller than the main flow line. The radiuses of the straight tees are produced in a way that has similar radiuses with the main flow line.
