the pakage of stainless steel 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.

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

The number of welds on a spool must be kept in a minimum count. The dimension of the spacing between circumferential welds and the center lines must not be larger than the four times the wall thickness of the pipe or fitting. After the main welds, tacks welds must be done precisely. All welds in the spools must be implemented according to proper Welding Procedure Specification (WPS). After the welding process is done, quality control of the components is performed by the specialists.

These connections are embedded inside concrete walls before the pouring of concrete. This system must be aligned properly before concrete pouring because it needs to withstand the weight and force of the structure.

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.

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.

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 625 / Inconel 625 is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance.

Pipe spools are produced by the usage of raw pipes and pipe fittings. The cutting process of the raw pipes is done with prespecified sizes that are suitable for the pipe fittings and other components.

The high chromium content promotes and maintains a passive film that protects the material in many corrosive environments.

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

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

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

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.

Resistant to a wide range of corrosive media. The chromium content gives better resistance than Alloy 200 and 201 under oxidizing conditions, at the same time the high nickel gives good resistance to reducing conditions.

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

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.

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

The strength of this nickel steel alloy is maintained to 1200¡ã F but stays ductile and tough down to temperatures of 400¡ã F. Its melting range is 2400-2460¡ã F.

Process equipment used in the production of chlorinated and fluorinated hydrocarbons.

316L also is a great stainless steel for high-temperature, high-corrosion uses, which is why it’s so popular for use in construction and marine projects.

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

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

316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”

Chromium, molybdenum, nickel and nitrogen all contribute to overall resistance to corrosion by various media

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.

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.

Hastelloy B2 is a nickel-molybdenum alloy especially suitable for handling equipment that reduces chemical environments. Such as applications in chemical processing industries involving sulfuric acid, phosphoric acid, hydrochloric acid and acetic acid.

Resistance to chloride ion corrosion is one of the main factors that facilitate the use of incoloy grades in different industrial applications.

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.
