304L couplings with tees 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.

Pipe spools are pre-shaped to make easier assemble using hoists, gauges and other tools for joining the parts. Pipe spools unite long pipes with flanges from the end of the long pipes so they can be bolted with each other with matching flanges.

There are different material grades used to produce these spools. The 304 stainless steel is the most used grade. The Sanitary Stainless steel 304 Tri Clamp Spool is made up of this material and has 3 clamps fitted for convenience of the customer. We also provide custom solutions to our customers. Please contact us for your needs.

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.

Nickel- and cobalt-based corrosion-, temperature- and wear-resistant alloys, such as Hastelloy B2, are classified as moderate to difficult when machined, but it should be emphasized that these alloys can be produced at satisfactory speeds using conventional production methods processing. During machining, these alloys harden rapidly, generate high heat during cutting, weld to the cutting tool surface, and provide high resistance to metal removal due to their high shear strength.

In nuclear reactors uses are for such components as control rod inlet stub tubes, reactor vessel components and seals, steam dryers and d separators in boiling water reactors.

Steel Pipe Spools are also referred as prefabricated components of a piping system such as pipes, flanges and pipe fittings, and they are mounted during the development before sending them to the manufacture.

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.

For service requiring optimum creep and rupture properties, Incoloy 800H or 800 HT are used. The high contents of nickel and chromium in the alloys also give good corrosion resistance.

Stainless steel 904L / 1.4539 material can be used to make hot and cold rolled sheet and strip, semi-finished products, bars, rolled wire and profiles, as well as seamless and welded pipes for pressure applications.

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site

However, their fatigue strength is higher than the slip-on flanges. A major problem of the socket weld flanges is the corrosion risk. A gap between the flange and fitting or pipe must be maintained before the welding. Corrosive fluids or humidity can locate in these shelters. Thus, this solid-liquid interface may cause corrosion on the body.

HASTELLOY C276 has exceptional resistance to strong solutions of oxidizing salts, such as ferric and cupric chlorides.

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

It was developed for enhanced creep resistance and for higher strength at temperatures above 1000¡ãF (537¡ãC).

316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”

Incoloy Alloy 800 is widely used in equipment that must have high strength and resistance to oxidation, carburisation and other harmful effects of high temperature exposure.

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.

The production process of the pipe spools has several stages. All stages are implemented for particular aims and the array between the stages is voluminous. Therefore, the manufacturing steps can be divided into marking, cutting, fit-up, welding, and painting.

A nickel alloy of this type also has great resistance to hydrochloric acid at different concentrations and temperatures.

Alloy 600 is non-magnetic, has excellent mechanical properties and a combination of high strength and good workability and is readily weldable.

The alloy’s properties make it an excellent choice for sea-water applications, including freedom from local attack (pitting and crevice corrosion), high corrosion-fatigue strength, high tensile strength, and resistance to chloride-ion stress-corrosion cracking.

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.

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.

This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

Alloy 600 is used in chemical and food processing, heat treating, phenol condensers, soap manufacture, vegetable and fatty acid vessels and many more.

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 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.

Hastelloy C-276 is the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.
