What is a Finned Tube
What is a Finned Tube? A finned tube (Finned Tube), as the name suggests, is a heat transfer tube with fins or projections on its surface. Also known as a fin tube or rib tube, the [...]
Factors Influencing the Determination of Pipeline Pressure Ratings
Factors Influencing the Determination of Pipeline Pressure Ratings Apart from the basic parameters of design temperature and design pressure used to determine the pressure rating of a pipeline, there are several other factors that will affect the determination of the pipeline's pressure rating. 1.2.1 Application Standard System Different standard systems have varying nominal pressure series and corresponding temperature-pressure tables. That [...]
Introduction to Pressure Bearing Standards for Steel Pipes
Introduction to Pressure Bearing Standards for Steel Pipes Pressure pipeline components are generally standard parts; therefore, the design of pressure pipeline components mainly involves the selection of these standard parts. Determining the pressure rating of the pipeline is essentially determining the rating of its standard parts. The pressure rating of a pipeline consists of two parts: The nominal pressure rating [...]
Pipe Pressure Ratings
Pipe Pressure Ratings The components of pressure pipelines are generally standard parts; therefore, the design of pipeline components mainly involves the selection of these standard parts. Determining the pipeline pressure rating is essentially determining the rating of its standard parts. The pressure rating of a pipeline consists of two parts: The nominal pressure rating of standard pipe fittings expressed in [...]
Welding of low-temperature steel pipes (A333-6) in LPG projects
Welding of low-temperature steel pipes (A333-6) in LPG projects In liquefied projects, pipelines generally use low-temperature pipes (A333-6). The process for welding this material is complex, and there is limited experience with welding these steel pipes domestically. To ensure the quality of welding for this material, we need to select welding materials based on its characteristics, establish welding procedures, and [...]
Classification of Pipeline Levels
Classification of Pipeline Levels 1. Overview In current Chinese regulations, industrial pipeline classifications can be divided into two systems. One is the classification system for pressure pipelines, involving regulations such as the Safety Technical Supervision Regulations for Pressure Pipelines – Industrial Pipelines TSG D0001-2009 and the Rules for Licensing Design of Pressure Vessels and Pressure Pipelines TSG R1001-2008. The other [...]
