Basic knowledge of straight seam steel pipe pressure pipe

Straight pipe joints Basics pressure pipe 

straight seam steel pressure conduit basic concept 

1) straight pipe joints pressure line defined 

on the sense that the straight pipe joints should include all pressure by a pressure conduit to transport gas or liquid conduit straight pipe joints. From the point of view of safety production, it is the name of the straight seam steel pipe pressure vessel. Therefore, it is not a pressure pipe in a simple sense. The possibility of accidents and the hazard of the accident define the scope of the straight seam steel pipe pressure pipe. . China (State Council Order No. 373) clarifies the scope of straight seam steel pipe pressure pipelines, and defines the definition of straight seam steel pipe pressure pipes. Pressure pipes use a certain pressure, which is used to transport gas or liquid tubular equipment, and the temperature is higher than or equal to the standard. A liquid medium with a boiling point and a nominal diameter of more than 25 mm. Straight seam steel pipe pressure equipment, in addition to its own blasting, will also cause explosions and fires due to leakage of the medium. It is very important to ensure the safe operation of straight seam steel pipe pressure pipelines. Therefore, like many countries, China has listed boilers as special equipment for national safety supervision. 

2 Straight seam steel pipe) Function and application of pressure pipe Straight seam steel pipe pressure pipe The straight seam steel pipe pressure pipe is an important part of the production process. Its main function is to use certain pressure, as well as distribution, metering, control and cutting. The role of the flow medium. The pressure pipeline is just like the blood vessels in the human body. 

Application of straight seam steel pipe pressure pipeline 

Transportation is one of the five major transportation industries along 

with railway, highway, water transport and shipping. Straight seam steel pipe pressure pipes are widely used in chemical, petroleum, electric power, metallurgy, city gas and heating systems, high temperature, corrosive, toxic and radioactive media, and the quantity and quality of straight seam steel pipe applications are important. status. 

The application of straight seam steel pipe pressure pipe is very extensive. It has been in the state of divisional management of the department since the private sector. All the lines of straight seam steel pipe manufacturing, installation, inspection, operation management and other aspects are self-contained, and the safety technology is different. Straight seam steel pipe The safety management of pressure pipelines is relatively perfect in terms of laws, regulations and standards compared to straight seam steel tube boilers and straight seam steel pipe pressure vessels. 

3) Terminology of straight seam steel pipe pressure pipe
Basic terminology and concept of pipe for straight seam steel pipe The pipe consists of straight seam steel pipe, pipe support and so on. Used to transport, distribute, control or stop fluid flow. 
The pipe system is referred to as the pipe system and is a plurality of pipes divided according to the fluid design conditions. Pipe components and straight seam steel pipes are called pressure pipe components. They are flanges, gaskets, tight parts, valves and special parts for pipes that are connected or assembled into pipes.
