A403 316L 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.

Hastelloy is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

This superalloy is used in a variety of industries such as aerospace, chemical processing, marine engineering, pollution-control equipment, and nuclear reactors.

HastelloyB2 is a nickel-based wrought alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. Therefore, it has strong resistance to stress corrosion cracking and pitting corrosion. It is also resistant to hydrogen chloride, sulfuric acid, acetic acid and phosphoric acid. Hastelloy B-2 is a grade of Hastelloy?, a nickel-molybdenum alloy. There are many different grades of Hastelloy?, including B-2. Hastelloy? grades are optimized for specific applications. molybdenum

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.

It is designed with a combination of impact toughness resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series.

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 can be used in reducing chemical environments and chemical processing industry.

Alloy 600 is non-magnetic, has excellent mechanical properties and a combination of high strength and good workability and is readily weldable.

Prefabricated steel s take advantage of offsite prefabrication to improve the speed or erection and cost predictability of the solution.

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.

Monel K500 is a precipitation-hardenable nickel-copper alloy that combines the excellent corrosion resistance characteristic of Monel 400 with the added advantage of greater strength and hardness.

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.

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.

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

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

?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.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

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.

Inconel 718 is a precipitation hardenable nickel-chromium alloy with high creep rupture strength at elevated temperatures around 700oC (1290oF). It is stronger than Inconel X-750 and has better mechanical properties at low temperatures than Nimonic 90 and Inconel X-750.

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

Hastelloy C-276 is easily fabricated by welding, using methods similar to those used for nickel-based alloys.

Prefabrication is the practice of assembling components of a structure in a workshop or other assembly facility before transporting to site for erection.

Stainless steel 904L / 1.4539 material can be used to make hot and cold rolled sheet and strip, semi-finished products, bars, rolled wire and profiles, as well as seamless and welded pipes for pressure applications.

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.

Hastelloy B3 is a nickel-molybdenum alloy with profound resistance to stree-corrosion cracking, pitting, corrosion and thermal stability greater to that of alloy B2.

The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.

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

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

Hastelloy C-276 resists the formation of grain boundary deposits in the weld heat affected zone, making it a candidate material for most chemical and petrochemical processing applications in the as-welded state. The alloy resists general and localized corrosion, including pitting, crevice corrosion and stress corrosion cracking.
