End

BE(Beveled End), PE(Plain End), BW(Butt Weld End), and NPT are different types of pipe end connections commonly used in various industries. These connections serve different purposes and have specific applications.
BE, also known as beveled end, refers to a pipe end that has been cut and prepared at an angle to form a bevel. This bevel allows for easy and smooth welding of pipes, especially in applications where a strong and leak-proof joint is required. Beveled end connections are commonly used in pipeline systems for oil and gas transportation.
On the other hand, PE, or plain end, refers to a pipe end that is cut straight and does not have any special preparation. This type of connection is typically used in applications where the pipes are joined using mechanical fittings such as flanges or couplings. Plain end connections are commonly found in plumbing systems, water distribution networks, and firefighting systems.
BW, which stands for butt weld end, is a type of pipe end connection that involves welding the pipes together end-to-end. This connection method creates a strong and permanent joint, making it suitable for high-pressure and high-temperature applications. Butt weld end connections are commonly used in industries such as oil and gas, petrochemical, and power generation.
Lastly, NPT, or National Pipe Thread, is a type of tapered thread connection commonly used in plumbing and fluid transfer systems. This type of connection requires the use of thread sealants to ensure leak-free joints. NPT connections are known for their versatility and are widely used in applications where easy assembly and disassembly of pipes and fittings are required.
In summary, BE, PE, BW, and NPT are different types of pipe end connections used in various industries. Each connection type has its own advantages and applications, and it is important to choose the appropriate connection method based on the specific requirements of the project.

Surface

To ensure high quality of the pipe, it is important to avoid any scale or contaminating exogenous iron particles. This can be achieved through the process of aid pickling, polishing, or brushing. While surface finishing through blasting or pickling may not be mandatory, bright annealing is essential to maintain the integrity of the pipe. This will ensure that the pipe is free from any impurities and ready for use in various applications.

Standard

JIS G3463, JIS G3459, DIN 17458, DIN 17456, EN10216-5, ASTM A213, ASTM A312 are some of the widely recognized standards in the field of stainless steel pipe specifications.
These standards play a crucial role in ensuring the quality, compatibility, and reliability of stainless steel pipes used in various industries.
ASTM A312 and ASTM A213 are American Society for Testing and Materials (ASTM) standards that provide guidelines for seamless and welded stainless steel pipes, respectively. These standards cover the dimensions, mechanical properties, and testing requirements for stainless steel pipes.
Similarly, EN10216-5 is a European standard that specifies the technical delivery conditions for seamless stainless steel pipes for pressure purposes.
DIN 17456 and DIN 17458 are German standards that define the general requirements and technical specifications for welded and seamless stainless steel pipes used in the food, chemical, and pharmaceutical industries.
JIS G3459 and JIS G3463 are Japanese Industrial Standards (JIS) that establish the specifications for stainless steel pipes used in high-temperature and corrosion-resistant applications.
Overall, these standards ensure the performance, safety, and compatibility of stainless steel pipes, enabling industries to rely on high-quality products for their specific needs.

Theoretical Weight (kg/m)

To calculate the weight per meter of a pipe, you need to know its outer diameter (OD) and wall thickness (WT) in millimeters. The formula is (OD-WT)*WT*0.02507. By applying this formula, you can determine the weight of the pipe per unit length, which is useful in various applications ranging from construction to manufacturing. Remember to ensure that the inputs are in millimeters to obtain an accurate output.
