304L pipes with WN 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.

625 has outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.

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.

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.

The outstanding and versatile corrosion resistance of INCONEL 625 alloy under a wide range of temperatures and pressures is a primary reason for its wide acceptance in the chemical processing field.

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

The joint is created by bolting two flanges to each other and sealing them by using various gaskets. Flanges are usually made of aluminum, bronze, brass or carbon steel. The most preferred material for general flange applications is the forged carbon steel. Moreover, flanges can be layered internally with different types of linings. Usually, flange material is selected as the same material with the pipe material. This material selection is conducted in order to prevent possible galvanic corrosion risks. The proper material selection for flanges is decided according to ASTM A-182 standards.

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

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

Alloy B2 is a highly resistant material to most organic and inorganic acids. It is a reduction resistant material.

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.

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

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

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

Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B2 is resistant to pure sulfuric acid and many non-oxidizing acids. This alloy should not be used in the presence of oxidative contaminants in oxidizing or reducing media. Premature failure may occur if Alloy B2 is used in the presence of iron or copper in systems containing hydrochloric acid.

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

Production of caustic alkalis particularly in the presence of sulfur compounds.

C276 is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Alloy C-276 is also defined as Alloy C276, Inconel C 276 or Hastelloy C, which is a superalloy with a perfect combination of molybdenum, nickel and chromium. Tungsten is added, which is designed to provide excellent corrosion resistance even in harsh environments.

There are different material grades used to produce these spools. The 304 stainless steel is the most used grade. The Sanitary Stainless steel 304 Tri Clamp Spool is made up of this material and has 3 clamps fitted for convenience of the customer. We also provide custom solutions to our customers. Please contact us for your needs.

The cylindrical bulge eases the use of flange in extreme conditions such as; elevated temperatures or high pressurized atmospheres. These flanges are welded to pipes or fittings by using butt-welding which enables a total fixation of the body. Slip-on flanges are also very common in use because of their low cost. They do not require excessive surface finishing as weld necked flanges.

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.

Inconel 625 alloy is widely used in chemical processing, pollution control, evaporators, nuclear reactors, marine industry and more.

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.

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 600 is used in chemical and food processing, heat treating, phenol condensers, soap manufacture, vegetable and fatty acid vessels and many more.

Prefabricated steel s as the name itself sounds, is made of pre engineered steel. Fabrication is done in controlled environment inside the factory and then sent to client location for assembly.

Just as the name ¡°Pre-engineered¡± suggests, these s are engineered at a factory and are assembled at site.

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.
