Inconel alloy 625, designated as UNS N06625, has the nominal composition of 60Ni–22Cr–9Mo–3.5Cb. Materials made from Inconel alloy 625 are widely applied for projects designed to ASME Boiler & Pressure Vessel Codes. They may be furnished in either solution annealed (Grade …

Concentrated solar power (CSP) is a typical renewable energy source which grows fast in areas with high solar irradiance such as Spain, India, South Africa, China, Chile, Australia, Middle East, Morocco, and the United States. The CSP plant generally consists …

Inconel alloy 625 flanges manufactured to ASME B16.5 fall into the Group 3.8 materials of the standard specification. They can be supplied in 7 classes: 150, 300, 400, 600, 900, 1500, 2500. Flanges with hub, such as weld neck, slip …

General Introduction The alloy 625 tubes, which are widely used for superheater or heat exchanger tubing, are generally manufactured as per ASTM B444 (ASME SB-444) UNS N06625. It is a typical nickel-chromium-molybdenum-columbium alloy, which is commercially known as a proprietary brand …

The weight of a CRA clad or lined steel pipe shall be calculated as the sum of the backing steel (usually the carbon steel or alloy steel pipe, base metal) weight and the CRA layer weight. No matter how the …

The natural gas or petroleum exploited from deep sea are usually transported by submarine pipeline. The pipe is generally carbon steel line pipe API X65 or X70. Its external surface is coated with special painting to withstand seawater corrosion. The …

The ERNiCu-7 electrodes are widely used for TIG or GTAW of Monel 400 materials. It shall be fabricated according to AWS A5.14 and its UNS number is N04060. This filler metal is also known as a proprietary brand Monel 60. …

Stainless steel 304L and 316L flanges are the low carbon version of stainless steel 304 and 316, respectively. According to ASME B16.5, they may be manufactured from forgings (ASTM A182 Gr. F304L/ F316L) or plates (ASTM A240 Gr. 304L/ 316L), respectively. …

Stainless steel 316 flanges(16Cr–12Ni–2Mo) may be manufactured from forgings (A182 Gr. F318), castings (A351 Gr. CF8M), or plates (A240 Gr. 316), respectively. The working pressures for which SS 316 flanges can be applied at elevated temperatures are listed in below two tables (it is …

Stainless steel 304 flanges (18Cr-8Ni) may be manufactured from forgings, castings, or plates, respectively. It includes ASTM A182 Gr. F304 forgings, ASTM A351 Gr. CF8 castings, and ASTM A240 Gr. 304 plates. The flange dimensions are generally in accordance with ASME …

The stainless steel tubing made of austenitic stainless steels shall be annealed or bright annealed after they are cold worked. The annealing or bright annealing processes not only eliminate residual stresses and improve its ductility, but also enhance the tubing‘s corrosion resistance by dissolving the …

Most stainless steel tubing is heat treated by the bright annealing process, in which the tubing is annealed in a protective medium to prevent discoloration of the bright surface. Since austenitic stainless steel is the most often used tubing material, the …
