End

NPT, BW (Butt Weld End), BE (Beveled End), PE (Plain End). To generate a highly similar content, we can rearrange the original text information as follows:
The various types of end connections for pipes include PE (Plain End), BE (Beveled End), NPT, and BW (Butt Weld End). These end connections offer different features and are commonly used in various applications. The PE (Plain End) connection provides a straight and smooth end, making it suitable for non-critical applications. The BE (Beveled End) connection, on the other hand, has a beveled edge that allows for easy welding and is commonly used in high-pressure applications. The NPT (National Pipe Taper) connection is a type of threaded end that ensures a tight and leak-proof fit. Lastly, the BW (Butt Weld End) connection involves welding the pipe directly to the adjoining pipe or fitting, offering a strong and durable joint. It's important to choose the appropriate end connection based on the specific requirements of the piping system.

Surface

To ensure that the pipe is free of any scale or foreign iron particles, it is recommended to undergo aid pickling, polishing, or brushing. It is not necessary to undergo pickling, blasting, or any surface finishing if the pipe has been bright annealed.

Standard

DIN 17456, DIN 17458, EN10216-5, JIS G3459, JIS G3463, ASTM A312, ASTM A213 are some of the commonly used standards in the field of industrial pipe manufacturing.
ASTM A312 and ASTM A213 are American standards that specify the requirements for seamless and welded stainless steel pipes, respectively. These standards outline the dimensions, mechanical properties, and testing procedures for these pipes, ensuring their quality and reliability in various applications.
EN10216-5 is a European standard for stainless steel seamless pipes used in pressure purpose applications. It provides specifications for the manufacturing, testing, and inspection of these pipes, guaranteeing their suitability for high-pressure environments.
DIN 17456 is a German standard that covers general requirements for seamless circular stainless steel tubes. It defines the dimensions, tolerances, and technical conditions for these tubes, reflecting the high standards of German engineering.
DIN 17458 is another German standard that focuses on the technical delivery conditions for welded austenitic stainless steel tubes. This standard outlines the manufacturing processes, testing procedures, and mechanical properties required for these tubes, ensuring their quality and durability.
JIS G3459 and JIS G3463 are Japanese standards for stainless steel pipes used in high-temperature and corrosion-resistant applications. JIS G3459 specifically addresses the requirements for stainless steel pipes used in piping systems for pressure service, while JIS G3463 focuses on the manufacturing methods and quality control of stainless steel tubes used for heat exchangers and boilers.
These standards play a crucial role in ensuring the compliance, safety, and performance of stainless steel pipes in various industries such as oil and gas, chemical, pharmaceutical, food processing, and power generation. By adhering to these standards, manufacturers and users can have confidence in the quality and reliability of the pipes they are using.

Theoretical Weight(kg/m)

To calculate the weight per meter of a pipe, you need to multiply the difference between the outer diameter and wall thickness by the wall thickness and then by 0.02491. Both the outer diameter and wall thickness should be measured in millimeters.
