304 tee with elbow and 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 is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

The surface edges of the components must be even and the surface impurities must be removed. A beveling process is implemented for the edges of the parts. A grinding machine is employed for the beveling process. The type of grinding machines for beveling differs for stainless steel components and carbon steel components.

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.

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).

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.

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

The corrosion resistance of Monel K-500 is basically the same as Alloy 400, except that in the age hardened condition, Alloy K-500 has a greater tendency to stress corrosion cracking in certain environments. Monel K-500 has been found to be resistant to sour gas environments.

316L, however, is a better choice for a project that requires a lot of welding because 316 is more susceptible to weld decay than 316L (corrosion within the weld).

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

304 stainless steel is the most common form of stainless steel in the world due to its excellent corrosion resistance and value. It contains 16% to 24% chromium and up to 35% nickel, as well as small amounts of carbon and manganese.

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.

Alloy 317L is non-magnetic in the annealed condition.

It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance.

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.

625 has almost complete freedom from chloride induced stress corrosion cracking.

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.

316L also is a great stainless steel for high-temperature, high-corrosion uses, which is why it’s so popular for use in construction and marine projects.

Alloy 317L can be easily welded and processed by standard shop fabrication practices.?

Alloy 317L has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, acidic chlorine and phosphoric acid.

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

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.

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available.

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

Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of greater strength and hardness.

The use of modular construction is directly influenced by the client¡¯s requirements for speed of construction, quality, added benefits of economy of scale, as well as single-point procurement.

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.

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.

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.

Virtually immune to chlorine ion stress corrosion cracking. Demonstrates adequate resistance to organic acids such as acetic, formic and stearic. Excellent resistance to high purity water used in primary and secondary circuits of pressurized nuclear reactors.
