304 pipes with flanges butt weld tee and elbows

When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.

Alloy 400 is a solid solution alloy that can only be hardened by cold working.

Inconel 600 exhibits cold forming characteristics normally associated with chromium-nickel stainless steels.

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

However, their fatigue strength is higher than the slip-on flanges. A major problem of the socket weld flanges is the corrosion risk. A gap between the flange and fitting or pipe must be maintained before the welding. Corrosive fluids or humidity can locate in these shelters. Thus, this solid-liquid interface may cause corrosion on the body.

It is used for components that require exposure to sea water and high mechanical stress.

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

Incoloy 800/800H/800HT are solid solution nickel chromium iron alloys with small additions of aluminium and titanium to improve corrosion and oxidation resistance.

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

Chromium, molybdenum and nitrogen increase resistance to pitting corrosion. Nickel imparts the austenitic structure.

HASTELLOY C276 is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications.

Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted together (i.e. temporarily connected). The resulting sub-assembly (part of the final pipe spool) continues with welding operations (i.e. permanent connected) before it comes back to the fitting table and gets fitted with other spool components.

The durability of steel is one of the best advantages of the pipeline systems. It is strong and it can withstand the pressures, temperatures, heavy shocks, and vibrations. It also has unique flexibility which provides an easy extension.

The corrosion resistance of Monel K-500 is basically the same as Alloy 400, except that in the age hardened condition, Alloy K-500 has a greater tendency to stress corrosion cracking in certain environments. Monel K-500 has been found to be resistant to sour gas environments.

AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.

It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 ¨C 1500¡ãF (427 ¨C 816¡ãC).?

Incoloy Alloy 800 is widely used in equipment that must have high strength and resistance to oxidation, carburisation and other harmful effects of high temperature exposure.

It has high resistance to oxidation at elevated temperatures up to 1050C.

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

904L grade stainless steel is unlike any other steel. Due to its extra amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids.

Pipe spools are pre-fabricated to reduce field installation costs and provide higher quality in the products. They are generally flanged to obtain the connection to other spools. The spool fabrication is normally performed by special companies having the required infrastructure.

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.

This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as Flue gas desulfurization and Chemical environments.

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

These specialist fabricators produce the system under the specified set of quality and accuracy to obtain proper fit at the site and to maintain the necessary technical properties defined by the client.

We manufacture piping products as well. When customers need different elements be fitted together before installation, the application of fabricated elements together is called the piping spool applications. There are Stainless Steel Pipe Spools products as well other material made spools in used.

One of the distinguishing features of Inconel 718¡¯s composition is the addition of niobium to permit age hardening which allows annealing and welding without spontaneous hardening during heating and cooling.

In most instances, the carbon content of the plate enables dual certification.

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.

316 can be annealed to resist weld decay.
