304L pipes with WN flanges

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.

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

HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

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

These have the advantage of nickel and molybdenum providing resistance against the most reducing environments. The oxidation resistance is also high in these materials due to the addition of the chromium content.

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

Thermal processing equipment in industrial applications, such as baskets, trays, and fixtures. In chemical or petrochemical processing it is used for heat exchangers and piping systems in nitric acid media, especially where resistance to chloride stress corrosion cracking is required.

For certain applications, grade 254 SMO has been reported to be a cost-effective substitute for high nickel and titanium alloys.

MONEL K-500 alloy has corrosion resistance comparable to 400, but has higher mechanical strength and hardness. Has good thermal corrosion resistance and long-term tissue stability. It is mainly used in the manufacture of turbine blades and gas turbine blades with a working temperature below 750¡ãC on aero-engines, and in the manufacture of fasteners and springs on ships; pumps and valve parts on chemical equipment, and scraping on paper-making equipment. Blades etc.

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.

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

Hastelloy B3’s distinguishing characteristic is its ability to maintain good ductility while transient exposure to intermediate temperatures.

This nickel alloy exhibits characteristics like good corrosion resistance, good weldability and high strength.

They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

Under alternating oxidizing and reducing conditions the alloy may suffer from selectiveo xidation.

A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.

Resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.

The addition of copper to this grade gives it better corrosion resistance than conventional chromium-nickel stainless steels, especially against sulfuric, phosphoric and acetic acids. However, the use of hydrochloric acid is limited.

The higher molybdenum content of Alloy 317L assures superior general and localized corrosion resistance in most media when compared with 304/304L and 316/316L stainless steels.

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

The Stainless Steel Fabricated Pipe Spools are useful for the customers in that they do not miss any parts and they eliminate the difficulty of onsite installation.

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.

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.

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.

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

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

Pipe Spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in fabrication shops.

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.

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.

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.
