nickel alloy Hastelloy C22 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.

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.

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

Thus, the pipeline system must be designed and produced in a way that can handle the induced stresses during the transportation of liquid or gaseous substances. Some facilities (power plants, petroleum refineries, etc.) require long and complicated pipeline systems. Moreover, these types of facilities handle problems because of the limited working space.

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.

It cannot be hardened by heat treatment;?however?the material will harden due to cold working.

Inconel is a superalloy made of high concentrations of nickel, chromium and molybdenum. Inconel 625 is highly resistant to corrosive and oxidizing media in a variety of environments. These alloys have excellent ductility and excellent formability. They can be welded easily and are resistant to post-weld carburization or graining.

Pipe spools are pre-shaped to make easier assemble using hoists, gauges and other tools for joining the parts. Pipe spools unite long pipes with flanges from the end of the long pipes so they can be bolted with each other with matching flanges.

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 plasma arc cutter is utilized for large pipes (above 28 inches of nominal pipe size) and its use is also beneficial for cutting off branches. If possible, an internal case must be located into pipes or fittings, in order to protect them from the spatters which are created by the plasma arc cutter. After the cutting, and edge preparation must be maintained.

ASTM A403 Pipe Spools, SS Pipe Spools,Stainless Steel Pipe Spools, WP Grade SS 304 Pipe Spools, DIN2617 SS Pipe Spool, DIN2616 SS Pipe Spool in China.

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.

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

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

Therefore the selected radius of the elbow can be very important. The other type of elbows is reducing elbows. In this type of elbows, the dimension of the center-line radius equals to the half of the nominal size of the larger end. Reducing elbows, again, maintain a 90¡ã flow change in the pipeline system. Moreover, a 180¡ãflow change can also be maintained by using a specific type of reducing elbow that is called ¡®return bends.

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

The whole butt weld system must be produced with the beveled ends. The 90¡ã butt welded elbows are produced to make a perpendicular angle in every direction. They can be supplied as short and long radius ones. The desired fixation and the correct centering between the components can be maintained via using a truly calculated radius.

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.

MONEL 400 solid solution alloy can be hardened by cold work, but can be hot worked or cold worked, then annealed into complex structures and welded using an appropriate welding process.

The alloy’s properties make it an excellent choice for sea-water applications, including freedom from local attack (pitting and crevice corrosion), high corrosion-fatigue strength, high tensile strength, and resistance to chloride-ion stress-corrosion cracking.

Hastelloy C-276 is the most common corrosion resistant material currently available, but it is not foolproof. Metals should not be exposed to high temperature, strong acid environment. Also, it is easier to work with cold working practices; hot working makes it easier to harden. If hot working, the temperature should be maintained between 1600¡ãF and 2250¡ãF.

Monel 400 is a nickel-copper alloy (about 67% Ni ¨C 23% Cu) that is resistant to sea water and steam at high temperatures as well as to salt and caustic solutions.

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.

Reworking of Alloy K-500 is best done while the material is in the annealed or hot worked and quenched condition. However, age hardened materials can be finished to close tolerances and finish. Therefore, the recommended practice is to machine slightly oversize, age harden, and then finish to size.

Alloy 317L has excellent corrosion resistance in a wide range of chemicals. It resists attack in sulfuric acid, acidic chlorine and phosphoric acid.

These have the advantage of nickel and molybdenum providing resistance against the most reducing environments. The oxidation resistance is also high in these materials due to the addition of the chromium content.

Elbows are generally used for a change in the direction of the flow. Common elbow systems can change the angle of the flow at 180¡ã, 90¡ã or 45¡ã. The 180¡ã elbow system is also called a ¡®return bend¡¯. The elbow systems can be classified into two groups which are butt weld elbows and reducing elbows. Butt-welded elbows are the most common and desired components.

In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. Furnace retort seals, fans and fixtures.

For the supply of water and flammable gases, steel pipes are the most useful pipes. They are used in many homes and businesses to transfer natural gas or propane fuel. They also used for fire sprinkler systems due to their high heat resistance.

Inconel 718 has become useful in a wide range of applications ranging from manufacturing operations to military equipment and the aerospace industry.

Under alternating oxidizing and reducing conditions the alloy may suffer from selectiveo xidation.
