stainless steel ASTM A403 WP316L heat pipes with 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.

Alloy K500 is refined by Electroslag Refining (ESR), ensuring the cleanest and highest quality material. This increased alloy purity limits the potential for hard non-metallic inclusions that can increase machining difficulty, machining time and ultimately lead to part failure. It also has low permeability and is non-magnetic at temperatures as low as -150¡ãF (-101¡ãC).

Alloy 904L outperforms other austenitic stainless steels due to the higher degree of alloying of nickel and molybdenum.

Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 ¨C 0.10) version of the alloy.

Alloy 254 SMO is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content.

Pipe spool systems are mostly used in power plants and petroleum refineries which requiring intensive piping. These systems include carriage and transport of fluid and gas and these transportation systems need lots of connection parts. In these systems, there is no place for mistakes.

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

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.

Blind flanges are the final division of the flange classification. They are used as end-closers for the pipes valves or pumps. Since blind flanges are used as obstacles against the fluid flow, they are the highest stressed parts of the flange systems.

The premium composition of molybdenum and nickel content of c276 is used to make nickel steel alloys. It helps resist crevice and pitting corrosion in reducing environments. Chromium, on the other hand, is used to impart resistance to oxidizing media.

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.

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.

Just as the name ¡°Pre-engineered¡± suggests, these s are engineered at a factory and are assembled at site.

Alloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100).

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.

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.

The alloy has good oxidation resistance and creep strength to 1500¡ãF (816¡ãC). It also possesses good low temperature toughness.

Alloy 347 stainless steel plate cannot be hardened by heat treatment, only by cold working.

Therefore, the fixation of the slip-on flanges is easier. However, the strength of the slip-on flanges is two-third of the weld necked flanges, under internal stresses due to flow. Another disadvantage of the slip-on flanges is that it¡¯s impossible to fix a flange to the elbow or fix a flange to the tee because the end surface of the slip-on fittings is not straight. The third flange group is the socket weld flanges. These flanges are utilized for small pipes that must yield high pressures. The strength of the socket weld flanges against internal stresses is equal to slip-on flanges.

This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors.

Hastelloy is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

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

Chromium is the principal agent for conferring corrosion resistance in neutral or oxidizing environments.

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

Alloy C-276 also has excellent resistance to pitting, stress-corrosion cracking and oxidizing atmospheres up to 1900¡ãF. Alloy C-276 has exceptional resistance to a wide variety of chemical environments.

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

Inconel 718 is a precipitation hardenable nickel-chromium alloy with high creep rupture strength at elevated temperatures around 700oC (1290oF). It is stronger than Inconel X-750 and has better mechanical properties at low temperatures than Nimonic 90 and Inconel X-750.

Inconel 718 is a nickel-based superalloy ideal for applications requiring high strength in the temperature range from cryogenic to 1400¡ãF. Inconel 718 also has excellent tensile and impact strength.

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.
