ASTM A312 TP316L Stainless Steel Seamless Pipe with Flange

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

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.

In today¡¯s world, pipelines are very common for almost every application that transports any liquid or gaseous substance. These liquid or gaseous substances flow in the pipe system with different pressures and temperatures. Therefore, pipeline systems are suffered from excess stresses that are produced by pressure and temperature.

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.

AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

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

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

Alloy 904L outperforms other austenitic stainless steels due to the higher degree of alloying of nickel and molybdenum.

?The low carbon content of Alloy 317L enables it to be welded without intergranular corrosion resulting from chromium carbide precipitation enabling it to be used in the as-welded condition.

A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.

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.

With the addition of nitrogen as a strengthening agent, the alloy can be dual certified as Alloy 317 (UNS S31700).

INCONEL 718 alloy was primarily chosen by design engineers for its high strength in extreme temperature conditions at both ends of the spectrum. It can be used from low temperatures all the way up to 1300¡ãF/704¡ãC. It exhibits extremely high yield, tensile and creep rupture properties across the entire range. It also exhibits excellent tensile and impact strength.

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.

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.

When in the age-hardened condition, Monel K-500 has a greater tendency toward stress-corrosion cracking in some environments than Monel 400. Alloy K-500 has approximately three times the yield strength and double the tensile strength when compared with alloy 400.

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

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.

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

The high amounts of nickel and chromium in austenitic stainless steels provide excellent mechanical properties, as well as excellent corrosion resistance.

Roller hearths and radiant tubes, in carbon nitriding processes especially.

It was developed for enhanced creep resistance and for higher strength at temperatures above 1000¡ãF (537¡ãC).

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 B3 suppliers and Hastelloy B3 manufacturers can be reached out to all over the country.

Prefabrication can be of many different types and undertaken at many different scales, from fabrication of small components and sub-assemblies through to large welded and bolted assemblies requiring significant logistical challenge to transport to site

This nickel steel alloy has good resistance to heat affected and knife-line zone attack. This alloy also bears the brunt of formic, sulfuric, phosphoric, acetic acids and various other non-oxidizing media.

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.

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.
