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

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.

Alloy X is known for its excellent high temperature strength and can withstand temperatures up to 2200¡ãF. The alloy can also be easily fabricated by manual and automated methods with forming and welding properties. In addition, Hastelloy X is resistant to corrosion, heat and oxidation and can withstand reducing or neutral atmospheres and oxidation.

Inconel 718 consists primarily of nickel (52%). Alloying elements include iron (19%), chromium (18%), niobium + tantalum (5%), molybdenum (3%), titanium (0.9%), aluminum (0.5%), in addition to other trace elements such as Baron, Cobalt, Copper, Manganese and Silicon.

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.

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.

Hastelloy B3’s distinguishing characteristic is its ability to maintain good ductility while transient exposure to intermediate temperatures.

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.

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

The alloy is capable of remaining stable and maintaining its austenitic structure. Incoloy 800 is primarily used in applications with temperatures up to 1100¡ã F, where alloys 800H and 800HT are normally used in temperatures above 1100¡ã F where resistance to creep and rupture is required.

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.

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

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

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.

Alloy 625 is generally supplied in the annealed condition, to provide utmost stability during fabrication and subsequent service.

This nickel alloy is used from cryogenic temperatures up to long term service at 1200¡ã F.

The specification of the flange types is done via the ASME B16.5 standards. Thus flanges are classified as; weld neck, slip-on, socket weld, lap-joint, threaded blind. The weld necked flanges are easy to recognize. A cylindrical bulge with a gradually increasing radius is connected to the main hollow part.

This nickel alloy is particularly resistant to hydrochloric and hydrofluoric acids when they are de-aerated. As would be expected from its high copper content, alloy 400 is rapidly attacked by nitric acid and ammonia systems.

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

The socket welded tees also make a perpendicular angle between the connected lines. They used for high-pressure applications. In opposition to the butt welded tees, the socket welded tees are utilized in applications where the radius of the pipes are generally smaller. The socket welded tees do not require the beveling process before welding. Therefore, these types of tees are favorable in some applications where branch ends must be kept in the same form before and after the welding.

The two most common stainless steel grades are 304 and 316. The main difference is the addition of molybdenum, an alloy that significantly improves corrosion resistance, especially in environments with more salt or chloride exposure.

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.

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.

For certain applications, grade 254 SMO has been reported to be a cost-effective substitute for high nickel and titanium alloys.

This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

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.

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

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.

The Stainless Steel Fabricated Pipe Spools are useful for the customers in that they do not miss any parts and they eliminate the difficulty of onsite installation.

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.
