Technical & Application

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 …

The shell-and-tube heat exchanger is a key piece of equipment for natural gas cooling on offshore platforms. The tube side is usually made of ASTM B338 grade 2 titanium U tubes. Its unique U-tube design and efficient heat transfer capabilities make it ideal for the limited space and harsh environmental conditions encountered on offshore platforms. 1. Design and Structure U-tube …

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 …

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 …

This power plant has a total capacity of power generation of 4800 MW. The photos presented below are U-shaped tubes made of ASTM A213 T22 alloy steel. These U tubes are supplied for the fabrication of superheaters, which …

What is instrumentation tubing? Instrumentation tubing, also known as instrument tubing, refers to specialized tubing designed and manufactured for use in instrumentation systems. These systems are utilized across various industries to measure, monitor, and control parameters such as pressure, temperature, flow rate, level, and composition in industrial processes. Instrumentation tubing serves as the conduit for transmitting fluids or gases to …

What is PTA? Purified terephthalic acid (PTA) is an important organic compound with the chemical formula C₈H₆O₄. It is the refined product of terephthalic acid (a white crystalline solid) and typically exists in the form of colorless crystals or white powder. PTA is a significant industrial chemical, primarily used in the synthesis of polyethylene terephthalate (PET), which is a polyester …

ASTM B111 is the standard specification for copper and copper-alloy seamless condenser tubes and ferrule stock. When dimensional inspection is finally conducted, outside diameter, wall thickness and length of the tubing shall be examined in accordance with Section 14 of the standard. The dimensions & permissible variations (tolerances) prescribed in Section 14 are applicable to ASTM B111 seamless condenser tubes …
