End

Beveled End (BE), NPT, Butt Weld End (BW), Plain End (PE). Let's rearrange the given content to create a similar description:
The different types of ends commonly used in various piping systems are Butt Weld End (BW), Plain End (PE), Beveled End (BE), and NPT. These ends are designed to cater to different connection requirements in the piping industry.
Plain End (PE) refers to pipe ends that are cut square without any specific design or shaping. This type of end is commonly used for non-critical applications where a seamless connection is not required.
Beveled End (BE) is characterized by a sloping edge or angle on the pipe end. It is primarily used in situations where the pipes need to be joined by welding. The beveled end ensures a smooth transition and provides better weld penetration.
NPT stands for National Pipe Taper and is a common thread type used in the piping industry. Unlike the previous two types, NPT refers to the threading of the pipe rather than the physical end shape. NPT threads are tapered and used for creating a tight seal between threaded pipes.
Butt Weld End (BW) involves joining pipes by welding the ends together. This type of connection is commonly used for critical applications and high-pressure systems where a secure, leak-proof joint is required.
In summary, the different types of end connections in piping systems include Plain End (PE), Beveled End (BE), NPT threaded connections, and Butt Weld End (BW). Each end type has its own application based on factors such as connection method, system requirements, and pressure conditions.

Surface

Pickling, polishing, and brushing are essential processes for the treatment of pipes. These processes aim to remove scale and foreign iron particles that may contaminate the pipes. It is important to ensure that the pipes are free from any impurities to maintain their quality and functionality.
Typically, pickling, blasting, or surface finishing methods are used to achieve this goal. However, it is worth noting that these methods are not obligatory when the pipe has undergone a bright annealing process. Bright annealing is a heat treatment process that results in a bright and shiny surface finish, eliminating the need for additional surface treatments.
Therefore, if the pipe has been bright annealed, there is no mandatory requirement for pickling, blasting, or surface finishing. However, it is crucial to ensure that the pipe is free from scale and any external iron particles to maintain its overall cleanliness and performance.

Standard

There are various standards that define the specifications for seamless and welded pipes used in various industries. Some of the commonly adopted standards are ASTM A312, ASTM A213, EN10216-5, DIN 17456, DIN 17458, JIS G3459, JIS G3463.
These standards provide guidelines on the size, shape, thickness, and material composition of pipes used in different applications. They specify the various tests and inspection methods that need to be performed to ensure the quality and durability of the pipes.
Manufacturers and suppliers of pipes need to comply with these standards to ensure the safe and reliable operation of the pipes in various industries such as petrochemicals, pharmaceuticals, food processing, and power generation. These standards have been developed after extensive research and consultation with industry experts to ensure that the pipes meet the varying requirements of different applications.

Theoretical Weight(kg/m)

To calculate the weight per meter of a pipe, you need to know both the outer diameter (OD) and wall thickness (WT) in millimeters. The formula for this calculation is (OD-WT)*WT*0.02491. This formula takes the difference between the outer and inner diameters (which is equal to the wall thickness) and multiplies it by the wall thickness and a conversion factor of 0.02491. The resulting value is the weight per meter of the pipe.
