Metalsin Tech supplies ASTM A269 TP316/316L tubing for the chromatography column industry. A chromatography column is an essential component of chromatographic techniques, used to separate and analyze mixtures of chemical compounds. It is a cylindrical tube filled with a stationary phase (solid or liquid), through which the mobile phase (liquid or gas) carries the sample mixture. The separation occurs based …

Methyl Ethyl Ketone (MEK), or butanone, is a volatile, colorless liquid primarily used as a solvent in coatings, adhesives, and chemical production. It is highly effective in dissolving resins and other synthetic polymers and serves as a degreasing agent and chemical intermediate. Methyl ethyl ketone is typically produced in petrochemical plants and refineries through the MEK unit, which is often …

What is a downhole chemical injection line? A downhole chemical injection line is a specialized tubing system used in oil and gas wells to deliver chemicals directly into the wellbore at specific downhole locations. These chemicals are injected to manage and mitigate various issues that can occur during the extraction of hydrocarbons, such as corrosion, scale formation, hydrate formation, and …

ASTM A789 is a standard specification for seamless and welded ferritic/austenitic stainless steel tubing, commonly known as duplex stainless steel. UNS S31803 and S32205 are two very commonly used grades under this specification. These tubes, either furnished in average wall thickness or minimum wall thickness, are manufactured for services requiring general corrosion resistance at temperatures usually no greater than 600°F …

Java-7 Power Plant The Java-7 power plant (also called PLTU Jawa 7) is a 2,100 MW coal-fired power plant (CFPP) comprised of two units located at Terate Village, Kramatwatu District, Serang Regency, Banten Province, Indonesia. This project is located on the island of Java, Indonesia, with a total investment of more than US$1.88 billion and a total installed capacity of …

Sizes & Wall Thicknesses Metalsin Tech supplies seamless and welded austenitic stainless steel feedwater heater tubes, which are manufactured in accordance with ASTM A688. These tubes may be furnished in straight length or be bent into the form of U-tubes for application in tubular feedwater heaters. The tubing sizes covered shall be 5/8″ to 1″ [15.9 mm to 25.4 mm] …

Metalin Tech supplies TP316 and TP316L welded austenitic stainless steel boiler, superheater, heat exchanger, and condenser tubes, which are manufactured in accordance with ASTM A249 (identical with ASME SA-249). Among the various grades specified under this standard, TP316 and TP316L are widely used due to their excellent corrosion resistance, high-temperature strength, and good weldability. Designated with nominal composition of 16Cr-12Ni-2Mo, …

ASTM A249 TP304/304L welded tubes are austenitic stainless steel tubes that meet the specifications of the ASTM A249 standard. These tubes are designed for high-temperature and high-corrosion applications such as in boilers, superheaters, heat exchangers, and condensers. TP304 and TP304L are the primary grades used accounting for more than 80% of the austenitic stainless steel production. ASTM A249 TP304 has …

The ASTM A249 tubes are nominal-wall-thickness welded tubes and heavily cold-worked welded tubes made from a series of austenitic stainless steels. These tubes are primarily used for the fabrication of boilers, superheaters, heat exchangers, or condensers. ASTM A249 is identical with ASME SA-249. The tubing sizes and thicknesses usually furnished to this standard are 1/8″ [3.2 mm] in inside diameter …

SJZ Metalsin supplies ASTM A213 TP347 and TP347H seamless tubes for heat exchangers, boilers and superheaters. As a modified version of the classic 304 stainless steel, niobium is added to oppose chromium carbide precipitation, which means to stabilize the carbon in TP347 stainless steel. The niobium added has significant importance: Improved resistance to intergranular corrosion at elevated temperatures: Niobium can …

ASTM A213 TP304H and TP316H are the “H Grades” of austenitic stainless steels designed for high-temperature applications. The letter H indicates its higher carbon content as well as the high-temperature service. Seamless tubes made of ASTM A213 TP304H (UNS S30409) and TP316H (UNS 31609) exhibit much better creep strength and creep-rupture strength at elevated temperatures, thus, are widely used for …

Sizes, wall thicknesses, tolerances & applications SJZ Metalsin supplies a series of seamless austenitic stainless steel boiler, superheater and heat exchanger tubes in the material grades of ASTM A213 TP304, TP304L, TP316, and TP316L. The tubing sizes usually are 1/8″ [3.2 mm] in inside diameter to 5″ [127 mm] in outside diameter. They may be furnished in minimum wall thickness …
