stainless steel 304/304L pipes with y tee elbows and 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.

Hastelloy C-276 is easily fabricated by welding, using methods similar to those used for nickel-based alloys.

One exception, however, are strongly oxidizing acids such as nitric acid. Alloys that contain molybdenum generally do not perform as well in these environments.?

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.

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.

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

The Alloy 800 series (Incoloy 800, 800H and 800HT) are nickel-iron-chromium superalloys that provide high temperature strength and resistance to oxidation, carburization and other types of high temperature corrosion. Alloy 800 (UNS N08800), Alloy 800H (UNS N08810) and Alloy 800HT (UNS N08811) have the same nickel, chromium and iron content, except for the total titanium and aluminium content (0.85 to 1.2%) to ensure optimum high temperature performance.

Monel K-500 combines the excellent corrosion resistance of Monel 400 with the added benefits of higher strength and hardness. Performance can be improved by adding aluminum and titanium to the nickel-copper matrix and by heating under controlled conditions to precipitate submicroscopic particles of Ni 3 (Ti, Al) throughout the matrix.

Therefore the selected radius of the elbow can be very important. The other type of elbows is reducing elbows. In this type of elbows, the dimension of the center-line radius equals to the half of the nominal size of the larger end. Reducing elbows, again, maintain a 90¡ã flow change in the pipeline system. Moreover, a 180¡ãflow change can also be maintained by using a specific type of reducing elbow that is called ¡®return bends.

Hastelloy B3 is a nickel-molybdenum alloy with profound resistance to stree-corrosion cracking, pitting, corrosion and thermal stability greater to that of alloy B2.

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.

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.

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.

Moly family has the ability to withstand high temperatures and maintain strength under volatile conditions.

The alloy is made up of 50-55% nickel+cobalt (with cobalt limited to 1% max) and 17-21% chromium.

Alloy 347 stainless steel plate exhibits good general corrosion resistance that is comparable to 304.

This nickel steel alloy is readily fabricated and may be welded in either the annealed or precipitation (age) hardened condition.

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

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

Inconel 625 alloy is widely used in chemical processing, pollution control, evaporators, nuclear reactors, marine industry and more.

The plasma arc cutter is utilized for large pipes (above 28 inches of nominal pipe size) and its use is also beneficial for cutting off branches. If possible, an internal case must be located into pipes or fittings, in order to protect them from the spatters which are created by the plasma arc cutter. After the cutting, and edge preparation must be maintained.

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.

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.

A Pre-engineered steel is basically a that is made up of steel.

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

Exposures like this are regularly experienced during heat treatments that are linked with fabrication.

For the supply of water and flammable gases, steel pipes are the most useful pipes. They are used in many homes and businesses to transfer natural gas or propane fuel. They also used for fire sprinkler systems due to their high heat resistance.

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.

316L is very similar to 316 in almost every way.?

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.
