Metalsin Tech supplies welded stainless steel sanitary tubes made in accordance with ASTM A270. These tubes are usually made from a variety of austenitic, or ferritic/austenitic duplex stainless steel grades. The welded stainless steel sanitary tubing shall be made using an automated welding process with no addition of filler metal during the welding process. These tubes are intended for use …

A maleic anhydride reactor is a specialized chemical reactor used to produce maleic anhydride (MA), typically through the partial oxidation of hydrocarbons such as n-butane or benzene. The reactor operates at high temperatures, often using vanadium-phosphorus oxide (VPO) catalysts to facilitate the oxidation process. Heat exchangers are incorporated to manage the heat released during the exothermic reaction, ensuring temperature control. …

Stainless steel 310S tubes refers to welded (ASTM A249) or seamless (ASTM A213) boiler, superheater, heat-exchanger and condenser tubes made from austenitic stainless steel TP310S. It is a modified version from 304 stainless steel with increased chromium and nickel for improved strength and better oxidation resistance at elevated temperatures. The primary feature of TP310S tubes is their excellent oxidation and …

Heat exchanger tubes made in accordance with ASTM A213 are seamless low alloy steel (Cr-Mo alloy steel) or austenitic stainless steel tubes used for heat transferring in high-temperature and corrosive applications. These tubes are known for their excellent mechanical properties, including strength and resistance to oxidation and corrosion in demanding environments. In a heat exchanger, the tube sheet is a …

In oil extraction, wellhead pressure monitoring is critical. Instrument tubing connects the pressure sensors in the oil well to ground-level control devices, measuring wellhead pressure and helping operators adjust production rates to prevent blowouts or pressure loss. The material used for instrument tubing in oil well pressure monitoring typically needs to withstand high pressure, corrosion, and maintain high strength, as …

The 904L seamless tubing usually refers to seamless boiler, superheater, and heat exchanger tubes made from super austenitic stainless steel UNS N08904 in accordance with ASTM A213 (ASME SA-213). 904L (UNS N08904) is a high corrosion-resistant austenitic stainless steel alloy with the nominal composition 44Fe-25Ni-21Cr-Mo. It offers exceptional resistance to general and pitting corrosion, especially in sulfuric and phosphoric acid …

ASTM A688 welded stainless steel tubes are usually furnished in the form of U tubes for application in tubular feedwater heaters. According to the supplementary requirement S1, each welded tube in finished condition prior to bending, shall be tested by passing it through an electric nondestructive tester capable of detecting defects on the entire cross section of the tube. This …

ASTM A249 welded stainless steel tubes are widely used in various industries working as heat exchanger, boiler, superheater, and condenser tubes. Compared to the seamless tubing, these welded stainless steel tubes offer several significant advantages: Cost Effective Manufacture The manufacturing process for ASTM A249 welded stainless steel tubes is more efficient and less costly compared to seamless tubes made to …

A surface condenser is a heat exchanger used to condense steam or vapor into liquid by passing it through tubes cooled by water or air, with the cooling fluid flowing outside the tubes. This non-contact design, commonly employed in power plants and industrial processes, ensures efficient heat transfer and allows the condensed liquid to be reused in a closed-loop system. …

Metalsin Tech supplies stainless steel TP316L welded tubes for shell-and-tube heat exchangers of gas treaters in rich amine service. Rich amine service involves handling and processing amine solutions that have absorbed acidic gases like hydrogen sulfide (H₂S) and carbon dioxide (CO₂) in gas processing or refining operations. These “rich” amine solutions are typically regenerated by heating to release the absorbed …

Chemical Composition Requirements ASTM A213 TP321 seamless tubes are a series of seamless boiler, superheater and heat exchanger tubes made from titanium-stabilized austenitic stainless steel 321. TP321 contains additional titanium to stabilize the carbon, improving its resistance to sensitization (the formation of chromium carbides) and subsequent intergranular corrosion in high-temperature environments. Compared to TP304 tubing, it exhibits improved corrosion resistance …

PVC coated stainless steel tubing, also known as stainless steel tubing with PVC coating, is generally a hollow product of round cross section made of stainless steel with an outer coating of PVC (polyvinyl chloride). The core tubing, either seamless or welded, is usually made of austenitic stainless steels in accordance with ASTM A269. It is primarily used for general …
