ASME SA 403 WP 304 Reducer is a butt welded fitting that reduces pipe diameter at the joint. Stainless steel 304 long radius elbows are another type of elbows with a radius more than twice the diameter of the pipe.

A butt weld pipe fitting is designed to be welded on site at its end(s) to connect pipe(s) together and allow change in direction or pipe diameter, or branching or ending.

This fitting then becomes part of a system for transporting fluids (oil, gas, steam, chemicals, …) in a safe and efficient manner, over short or long distances.

S31803 is the Unified Numbering System (UNS) designation for the original duplex stainless steel. The UNS system was created by multiple trade groups in the 1970s to reduce confusion when the same alloy was called different things, and vice versa. Each metal is represented by a letter followed by five numbers, where the letter represents the metal series, i.e. S for stainless steel.

For paper mill applications requiring lower alloy grades that do not have sufficient corrosion resistance. Based on a 22% chromium content, they have a combined austenitic:ferritic microstructure that provides greater strength, corrosion resistance and cost-effectiveness.

The UNS S31803 (ASTM F51) specification has been largely superseded by UNS S32205 (1.4462, ASTM F60). This reflects their desire to maximize the alloy’s corrosion properties, thanks to the development of the AOD steelmaking process, which allows for tighter control of composition. In addition, it allows to influence the nitrogen addition level rather than just being present as a background element. Therefore, the highest performing duplex grades seek to maximize the content of chromium (Cr), molybdenum (Mo) and nitrogen (N).

Titanium was discovered in 1791 by the English chemist and mineralogist William Gregor. He thought it was a compound. Later, it was named after the Titan of Greek mythology by the German chemist Martin Heinrich Klapros.

Stainless steel is an alloy of iron that is resistant to rusting and corrosion. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen
Completely and infinitely recyclable, stainless steel is the ¡°green material¡± par excellence. In fact, within the construction sector, its actual recovery rate is close to 100%.
Stainless steel is also environmentally neutral and inert, and its longevity ensures it meets the needs of sustainable construction. Furthermore, it does not leach compounds that could modify its composition when in contact with elements like water.
Stainless steel must contain at least 10.5 percent chromium. Depending on the grade, it may contain much higher chromium levels, and additional alloying ingredients like molybdenum, nickel, titanium, aluminum, copper, nitrogen, phosphorous or selenium.
In addition to these environmental benefits, stainless steel is also aesthetically appealing, extremely hygienic, easy to maintain, highly durable and offers a wide variety of aspects. As a result, stainless steel can be found in many everyday objects. It also plays a prominent role in an array of industries, including energy, transportation, building, research, medicine, food and logistics.

This nickel alloy provides excellent resistance to hydrochloric acid at all concentrations and temperatures. In additions, Hastelloy B2 pipe bend has excellent resistance to pitting, stress corrosion cracking and to knife-line and heat-affected zone attack.

The 316L is a low carbon version, while the 316H type is a high carbon version of 316 stainless steel. Meanwhile, the 316Ti is a titanium stable version of the 316. Anti-sensitization is achieved in type 316Ti by adding titanium to stabilize the structure to prevent the precipitation of chromium carbide, which is the source of sensitization.

Hastelloy Fittings and Hastelloy Butt Welded Fittings are typically used in applications where high temperatures are present due to the thick and stable passivating oxide layer formed when the Hastelloy is heated. This layer protects the surface of the Hastelloy butt welded fitting, making it heat resistant.

Duplex steels are stainless steels, also known as duplex steels due to the presence of two phases in their metallurgical structure. This duplex steel is designed to provide better corrosion resistance and higher strength than other aesthetic stainless steels.

Alloy C22 is a nickel-chromium-molybdenum solid solution strengthened super-alloy with a nominal chemical composition of 56% nickel, 22% chromium, and 13% molybdenum, with additions of iron, tungsten, and cobalt.

Hastelloy C276 is one of the few grades resistant to wet chloride gas and chlorine dioxide.

The Stainless Steel 304 Fittings one of the most commonly used types of pipe fittings all over the world.

In fact, the above properties of 317L fittings are considered to be much better than traditionally used stainless grades such as 304, 304L, 316 and 316L. The alloys used for stainless steel 317L are known to provide better resistance than 316L, especially in highly corrosive environments, which may contain chemicals such as sulfur-containing media, chlorides and other halides.

Duplex UNS S31803 butt welded pipe fittings are duplex ferritic austenitic 22% chromium, 3% molybdenum, 5% to 6% nickel alloy stainless steel. Duplex UNS S31803 butt welded pipe fittings are formed according to the crystal structure of stainless steel.

Stainless steel pipe fittings are used to connect 2 pipes as they have a pipe fitting at one or both ends. The stainless steel reducing tee has a tensile strength of 515 MPa and a yield strength of 205 MPa.

Among the various grades of stainless steel, one grade is austenitic steel containing columbium. Fittings made from it are called stainless steel 347 fittings. They are widely used at high temperatures and have amazing forming and welding quality. The addition of columbium to stainless steel 347 weld fittings provides resistance to intergranular corrosion. It also shows improved corrosion resistance in strongly oxidizing environments. They are widely used to install, connect and configure other products.

In addition to the properties of 304, 316 stainless steel long and short tube ends have increased corrosion resistance due to the addition of molybdenum to their composition. There are duplex steel short end flanges and fittings.

304L stainless steel construction. It is composed of chromium-nickel material and has very good corrosion resistance. Couplings are suitable for unthreaded pipes in air, water, oil and gas applications.

The major differences between these alloys are their mechanical properties which stem from the restricted compositions of alloys 800H and 800HT and the high-temperature anneals used for these alloys.
