What is a heat exchanger? A heat exchanger is a device designed to transfer heat from a hotter fluid to a cooler fluid. What is the heat transfer area of a heat exchanger? The heat transfer area is calculated as the outer surface area of the tube, considering the outer diameter and deducting the length that extends into the tube sheet. In U-tube heat exchangers, the area of the U-shaped bend is typically excluded.
1. What are the primary structural types of pressure vessels? Pressure vessels come in various structural forms, including spherical, cylindrical, box-shaped, and conical vessels. 2. What role do reaction pressure vessels play in production, and what are some common types? Reaction pressure vessels are essential for conducting physical and chemical reactions in the production process. Examples include reaction kettles, decomposition kettles, vulcanization tanks, decomposition towers, polymerization...
What Other Classification Methods Are There for Pressure Vessels? Categorized by vessel wall thickness: Containers are classified as thin-walled (wall thickness ≤ 1/10 of the inner diameter) or thick-walled. Based on shell geometry: Containers are grouped as spherical, cylindrical, or special-shaped. By manufacturing method: Containers are identified as steel structure, casting, or machining containers. Considering structural materials: Containers are classified as steel structure, cast...
To streamline safety management and regulatory oversight, the "Capacity Regulation" categorizes containers into three types based on pressure level, medium harm, and production role: Class I Pressure Vessels: Low-pressure vessels (excluding Class II and Class III). Class II Pressure Vessels: 1. Medium-pressure vessels (excluding Class III). 2. Low-pressure reaction and storage vessels with flammable or moderately hazardous media. 3. Low-pressure containers with extremely toxic and highly...
Following the operational principle in the manufacturing process, pressure vessels are categorized into reaction pressure vessels, heat exchange pressure vessels, separation pressure vessels, and storage pressure vessels. When a pressure vessel performs multiple functions simultaneously, it should be classified based on its predominant process function.
The Heat Exchanger Pressure Vessel is primarily utilized for medium heat exchange, encompassing devices like shell-and-tube waste heat boilers, heat exchangers, coolers, evaporators, heaters, and more. What are examples of typical heat exchange containers? In the production process, the Heat Exchanger Pressure Vessel facilitates medium heat exchange. It includes various containers such as tubular waste heat boilers, heat exchangers, coolers, condensers, evaporators, heating pots, disinfection pots,...
Pressure vessels can be classified based on various factors, including pressure-bearing methods, design temperature, and installation method. 1. Pressure-Bearing Methods: Pressure vessels are categorized into two major types based on pressure-bearing methods: (1) Internal Pressure Vessels: These containers have media pressure inside the shell. The design focuses on wall thickness determined by strength calculations. (1) External Pressure Vessels: These containers have media pressure outside the...
Pressure vessels are categorized based on pressure levels, which include low pressure, medium pressure, high pressure, and ultra-high pressure: Low Pressure Pressure Vessels(Code L): Pressure ranging from 0.1MPa to less than 1.6MPa. Medium Pressure Pressure Vessels(Code M): Pressure from 1.6MPa to less than 10MPa. High Pressure Pressure Vessels(Code H): Pressure from 10MPa to less than 100MPa. Ultra-High Pressure Pressure Vessels(Code U): Pressure equal to or exceeding 100MPa.
Pressure vessels must exhibit specific performance characteristics suitable for the process, ensuring safety, reliability, ease of manufacturing and installation, advanced structure, convenient maintenance, and economic rationality. The design of pressure vessels should adhere to the following criteria: (1) Strength: This pertains to the container's capacity to withstand pressure or other external loads without cracking or undergoing excessive deformation. (2) Stiffness: This refers to the container's...
