Because of the use in this way, there is often a risk of leakage, explosion, because the substances contained in these containers are often flammable or cause very high pressure. We have made the following basic classifications of pressure tanks and boilers.<\/p><h3>Classification of pressure tanks according to operating temperature:<\/h3><ul><li>Cryogenic pressure vessels: Designed for temperatures typically below -150\u00b0C (-238\u00b0F), these containers store and transport cryogenic liquids such as liquid nitrogen. Carbon steel that can be used for this type of steel is <a href=\"https:\/\/leongjin.co.th\/en\/products\/plate-steel\/pressure-vessel-hot-resistant-steel-plate\/sa516-gr70\/\"><span style=\"color: #800000;\"><strong>ASME SA516-70<\/strong><\/span><\/a><\/li><li>Low Temperature Pressure Tank: Operates above cryogenic temperature but below ambient temperature.

This must take into account the specific requirements for safe operation.<\/p><p>In addition to classifying pressure tanks according to temperature, it may also be classified from pressure tanks and boilers or boilers according to their design. It can be of different types as follows:<\/p><h3>Classification of pressure tanks by shape:<\/h3><ul><li>Cylindrical pressure vessels: the most common shape Used for storage tanks. Reactors and heat exchangers<\/li><li>Circular pressure vessels: Ideal for storing high-pressure gases and liquids due to their shape, which have uniform stress distribution.<\/li><li>Square pressure vessels: Less common due to the challenge of guaranteeing uniform stress distribution and more complex construction.<\/li><li>Conical pressure vessels: Used in specific applications where the shape is beneficial to material flow or pressure distribution.<\/li><\/ul><h3>Classification<\/h3><h3>Types of boilers or boilers:<\/h3><ul><li>Fire tube boiler: hot gas flows through pipes surrounded by water. Used for low to medium steam requirements.<\/li><li>Water Tube Boiler: Water flows through pipes heated by the surrounding hot gas, suitable for high steam demand and pressure conditions.<\/li><li>Vertical boilers: there are vertical cylinders used in small space applications.<\/li><li>Horizontal boiler: The core of the boiler is horizontal. This is common in industrial applications.<\/li><li>Natural Circulation Boiler: Relies on natural convection for water circulation.<\/li><li>Forced circulation boiler: uses a pump for water circulation, which is used for the generation of high-pressure and high-capacity steam.<\/li><li>Internal Combustion Boiler: The furnace is located inside the boiler shell, which is common in most boiler applications.<\/li><li>Externally combusting boiler: The furnace is located outside the boiler shell, giving it more burner volume and making it easier to manage combustion.<\/li><\/ul><p>These categories help to choose the right type of pressure vessel or steam boiler for a particular application. This ensures efficiency, safety, and compliance with industry standards.<\/p><p>Carbon steel materials used in cryogenic tanks and steam boilers specific requirements in design, manufacture, inspection, testing are tools to ensure that materials can withstand extreme conditions. It is designed and built with engineering principles to ensure safety.<\/p><h4>Some important requirements for Cryogenic Tank and Steam Boiler:<\/h4><ul><li>ASTM A333 grade 6: It is a general specification for carbon steel pipes. Alloy doped pipes and seamless pipes, seamless and welded pipes for low temperature applications.<\/li><li>ASME VIII or Boiler and Pressure Vessel Specification: This specification details the procedure for the construction of pressure vessels, including those used at freezing temperatures, and covers materials, design, fabrication, and other materials. Inspection and Testing<\/li><li>ASTM A210: This specification covers boilers made of medium carbon steel and heater tubes.<\/li><\/ul><p>These specifications are of great importance in ensuring that the materials used in the construction of cryogenic tanks and boilers can operate safely and efficiently under conditions where there is a need for cryogenic storage or high-pressure steam generation. It is important to consult with a materials expert and follow the latest standards and requirements when designing and building these systems to ensure safety.<\/p><p>In Leong Jin, we sell steel to make boilers.
