ASTM A312 TP316 Stainless Steel Seamless Pipe with 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.

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.

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

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

Alloy 400 is a solid solution alloy that can only be hardened by cold working.

With the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700).

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

When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.

Inconel is a superalloy made of high concentrations of nickel, chromium and molybdenum. Inconel 625 is highly resistant to corrosive and oxidizing media in a variety of environments. These alloys have excellent ductility and excellent formability. They can be welded easily and are resistant to post-weld carburization or graining.

With this advantage, all of the pipeline using industries has a great opportunity to increase their pipeline system efficiency and decrease their need for workforce and time.

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.

C276 is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Hastelloy B2 is a nickel-molybdenum alloy especially suitable for handling equipment that reduces chemical environments. Such as applications in chemical processing industries involving sulfuric acid, phosphoric acid, hydrochloric acid and acetic acid.

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.

Prefabrication is the practice of assembling components of a structure in a workshop or other assembly facility before transporting to site for erection.

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.

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.

Typical corrosion applications include titanium dioxide production (chloride route), perchlorethylene syntheses, vinyl chloride monomer (VCM), and magnesium chloride.

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

Process equipment used in the production of chlorinated and fluorinated hydrocarbons.

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.

It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 ¨C 1500¡ãF (427 ¨C 816¡ãC).?

Some typical applications for Inconel 625 include chemical processing, aerospace and marine engineering, pollution control equipment and nuclear reactors.

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.

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

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.

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 pipeline system must be produced and mounted away from the facility site. These complex facilities use pipe spools with different measurements and various components. Pipe spools are the prefabricated segments that include pipes, flanges, and fittings. Pipe fittings are the components that connect the complex pipe network. Moreover, pipe fittings change the piping systems¡¯ either sizes or dimensions. There are various types of fitting components but they can be briefly divided into three groups which are elbows tees and flanges.

When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400.

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.
