ASTM A312 TP 316L 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.

Prefabricated steel s as the name itself sounds, is made of pre engineered steel. Fabrication is done in controlled environment inside the factory and then sent to client location for assembly.

Hastelloy B2 prevents the formation of grain boundary carbide precipitates in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat affected weld zone reduces the precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

MONEL K-500 alloy has corrosion resistance comparable to 400, but has higher mechanical strength and hardness. Has good thermal corrosion resistance and long-term tissue stability. It is mainly used in the manufacture of turbine blades and gas turbine blades with a working temperature below 750¡ãC on aero-engines, and in the manufacture of fasteners and springs on ships; pumps and valve parts on chemical equipment, and scraping on paper-making equipment. Blades etc.

Hastelloy B-2 is a nickel-base wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures.

It can be easily welded and processed by standard shop fabrication practices.

Alloy K500 is refined by Electro Slag Refining (ESR), ensuring the cleanest and highest quality of material is supplied.

Alloy B-2 has poor corrosion resistance to oxidizing environments, therefore, it is not recommended for use in oxidizing media or in the presence of iron or copper salts, which may cause rapid premature corrosion failure.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

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.

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

304 stainless steel does have one weakness: it is susceptible to corrosion from chloride solutions or saline environments such as the coast.

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

For service requiring optimum creep and rupture properties, Incoloy 800H or 800 HT are used. The high contents of nickel and chromium in the alloys also give good corrosion resistance.

The sluggish age-hardening response of alloy 718 permits annealing and welding without spontaneous hardening during heating and cooling.

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.

They generally easily corrode because of the elements they exposure; water and natural electrolytes. Acceptable protective monitoring must be done when applying pipe spool systems.

625 has outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.

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.

Pipe spool fabrication is very important because the construction of the ship and other marine industries require intensive piping. Pipe spools create great advantages because they reduce the limitations of space on site.

As a corrosion resistant alloy, Monel 400 can withstand high temperature steam environments and fast flowing brackish/seawater, while maintaining excellent resistance to stress corrosion cracking in most fresh waters.

The versatility of INCONEL 600 alloy allows it to be used in a variety of applications involving temperatures ranging from cryogenic temperatures to over 2000¡ãF (1095¡ãC).

This alloy is widely used in the chemical industry for its strength and corrosion resistance. Applications include heaters, stills, bubble columns, and condensers for fatty acid processing; evaporator tubes, tube sheets, and sheeting trays for the manufacture of sodium sulfide; and equipment for processing abietic acid in pulp production.

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 tees are also used for the change of the flow angle and distribution of the flowing matter either into one or more channels. Tees can be divided into two main groups which are the butt welded tees and the socket welded tees. The butt welded tees are utilized to perform a perpendicular distribution of the flow. They make 90¡ã branches with the connection of the pipeline and distribute the coming matter from the mainline.

As a beginning of the manufacturing, all components must be marked in order to increase the monitorability of the materials. The marking work can be implemented due to the respective number of components. Moreover, all dimensions of the pipe spools must be marked on to themselves. The traces on the components must not contaminate the material otherwise traces can react with the material and this may cause deleterious problems.

Alloy 400 is low in strength in the annealed condition so, a variety of tempers may be used to increase the strength.

It is known to possess excellent workability as well.

Alloy 625 has excellent fatigue strength and stress corrosion cracking resistance to chloride ions. This nickel alloy has excellent weldability and is often used to weld AL-6XN. This alloy is resistant to a variety of severe corrosive environments, especially pitting and crevice corrosion.

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.

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.
