316L Stainless Steel Tube

Size

The outer diameter of the pipe ranges between 6.0 to 1219mm, with a wall thickness of 0.5 to 100mm. The pipes come in various lengths, ranging from 5.8m to 18m, with standard lengths being 6m and 11.8m. These specifications provide flexibility in choosing the right size for different industrial applications.

End

BE, NPT, BW, and PE are commonly used abbreviations in the field of pipe fittings.
- BE refers to Beveled End, which is a type of pipe end that has been cut at an angle to form a bevel. This bevel allows for easier welding and ensures a strong and secure connection.
- NPT stands for National Pipe Thread, which is a standardized thread type used for joining pipes and fittings. NPT threads are tapered, creating a tight seal when they are tightened together.
- BW, or Butt Weld End, is a type of pipe end that is prepared for butt welding. Butt welding involves joining two pieces of pipe by heating the ends and then pressing them together. This method creates a seamless and leak-proof connection.
- PE, or Plain End, refers to a pipe end that is plain and not prepared for any specific type of connection. When using a plain end pipe, additional fittings or couplings are typically required to create a secure joint.
In summary, these abbreviations are commonly used in the pipe fitting industry to describe different types of pipe ends and connections. Each abbreviation represents a specific preparation or design that is necessary for a particular type of connection.

Surface

To achieve a clean and polished finish, it is important to eliminate any scale or foreign iron particles present in the pipe. This can be accomplished through the process of aid pickling, polishing, or brushing. It is not necessary to undertake additional steps such as pickling, blasting, or surface finishing if the pipe has already undergone bright annealing. By following these steps, the pipe will be free of contaminants and possess a pristine appearance.

Standard

DIN 17456, DIN 17458, JIS G3459, JIS G3463, ASTM A312, ASTM A213, EN10216-5 are well-known standards in the field of industrial piping. These standards ensure the quality and reliability of pipes used in various applications.
ASTM A312 is the standard specification for seamless, welded, and heavily cold-worked austenitic stainless steel pipes. This standard covers both hot-finished and cold-finished pipes for high-temperature and general corrosive service.
ASTM A213, on the other hand, specifies seamless ferritic and austenitic alloy-steel boiler, superheater, and heat-exchanger tubes. It covers tubes made from different grades of alloy steel suitable for high-temperature service.
EN10216-5 is a European standard that specifies the technical delivery conditions for seamless and welded tubes of stainless steel. These tubes are intended for pressure purposes, high-temperature applications, and corrosive environments.
DIN 17456 is a German standard that covers general-purpose seamless circular stainless steel tubes. It specifies dimensions, tolerances, and technical delivery conditions for tubes used in various industries like chemical, petrochemical, and food processing.
DIN 17458, on the other hand, deals with seamless circular austenitic stainless steel tubes subject to special requirements. These requirements include elevated temperature properties, corrosion resistance, and dimension tolerances.
JIS G3459 is a Japanese industrial standard that specifies stainless steel pipes used in piping for corrosion resistance and low temperature services. This standard covers both seamless and welded pipes for various applications in industries like chemical, petroleum, and natural gas.
Lastly, JIS G3463 is another Japanese standard that specifies stainless steel tubes for general service. It covers both seamless and welded tubes used in heat exchangers, boilers, and condenser tubes.
These standards provide guidelines for the manufacturing and testing of pipes and tubes, ensuring their quality, durability, and suitability for specific applications. By adhering to these standards, manufacturers can ensure the reliability and performance of their products.

Theoretical Weight(kg/m)

To calculate the weight per meter of a pipe, you need to know the outer diameter (OD) and wall thickness (WT) of the pipe, both of which should be given in millimeters (mm). The formula to use is (OD-WT)*WT*0.02507. This will give you the weight per meter of the pipe in kilograms.
