This is called as the “center to face” distance and is equivalent to the radius through which the ASTM A234 gr WPB elbow is bent.

The superposition of residual stress caused by cold working and aging thermal stress, as well as the preferential embrittlement of the surface layer at the initial stage of aging, are the main reasons for aging cracking of Monel K500 alloy.

When we call a steel tee ¡°equal tee¡±, means the branch diameter of this tee is same with the main pipe (Run pipe) diameter of this tee. When we see only one size of tee in its description, it means this tee is the equal tee. for example, 8¡å tee mean the tee main pipe and branch pipe both are 8 inches. Sometimes the equal tee also described 8¡åX8¡å which is the same meaning of 8¡å tee.

Based on SW tee forms, the branch end will be threaded to male or female. So there are male branch tee and female branch tee, which if the tube with male NPT threads, then the tee shall be with female NPT threads.

ASTM A420 WPL6 Pipe Fittings such as WPL6 Caps, A420 WPL6 Weld Fittings, and SA 420 WPL6 Elbow. Our stock of low temperature steel fittings includes A420 Grade WPL6 fittings in a complete range of sizes and thicknesses.

They are generally used to attach (or join) two or more pipes (or tubes) together using pipe fittings. They help to make the joint stronger by adding additional strength to the joint, thereby helping to maintain the position of joint with increased stability. Pipe Fittings helps to change the direction of pipe/tube and ensures smooth flow of the content within. Pipe Fittings are also known as Buttweld Fittings.

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.

In order to convey the pipeline, it is necessary to remove the straight hose in the pipeline. When using various pipelines, various pipelines must be used. When the pipeline is used, the elbow must be used to change the size of the pipeline. When bifurcating, the three-way pipe The flange connection used when the joint is used with various pipe joints, in order to reach the long-distance transmission pipeline, in order to reach the thermal expansion and cold contraction joint or effective connection aging of the pipeline, the long-distance expansion and cold contraction joint is used for the connection of the pipeline. , In the connection of various instruments, there are also the connectors and plugs of the instrument phase.

Forged fittings produced in a facility covered by the ASME B16.9 standard must be manufactured in accordance with ASTM A 403. Molybdenum bearing stainless steel 316L fittings are also known as marine grade due to their excellent resistance in marine environments. While the chemical composition of grade 316L is similar to that of grade 316 stainless steel, the main difference between the two alloys is the nitrogen and carbon content.

Of all the duplex steel categories, standard duplex steels are the most widely used alloys. As a cost-effective alternative to nickel-rich alloys, duplex fittings offer moderate performance. However, the mechanical properties of duplex steels are much higher compared to austenitic alloys such as 304.

Alloy 800H/800HT is frequently used in applications that involve long-term exposure to elevated temperatures where resistance to oxidation, carburization and other types of elevated temperature corrosion is required.

T In the normal case, the stainless steel stub end is welded to the pipe, allowing the free lap pipe flange to pivot around the stub end; it eliminates the bump gap arrangement problem.

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).
