TP 304 Stainless Steel Pipe

TP304 stainless steel pipe is known for its excellent performance in corrosive environments, resistance to oxidation, and ease of fabrication. It can be welded and formed into various shapes, including round, square, and rectangular. TP304 stainless steel pipe is also available in various types, including seamless, welded, and annealed.

The TP304 Stainless Steel Pipe specification includes:

Size: The standard size range of TP304 stainless steel pipes is 1/8” NB to 24” NB.

Schedule: The schedule range of TP304 stainless steel pipes is SCH 5, SCH 10, SCH 20, SCH 40, SCH 80, SCH 160, SCH XXS.

Length: The standard length of TP304 stainless steel pipes is 6 meters or 12 meters, but custom lengths can also be provided.

End Types: The TP304 stainless steel pipes are produced with various types of ends like plain end, beveled end, treaded end, and coupling.

Material: The material used in manufacturing TP304 stainless steel pipes is Austenitic Stainless Steel.

Standard: The TP304 stainless steel pipes conform to ASTM A312 / ASME SA312, ASTM A358 / ASME SA358, and ASTM A376 / ASME SA376 standards.

Wall Thickness: The TP304 stainless steel pipes are available in various wall thicknesses like Sch.5S, Sch.10S, Sch.40S, and Sch.80S.

Applications: TP304 stainless steel pipes are widely used in applications like chemical processing, food processing, oil and gas industry, petrochemical industry, pharmaceuticals, water treatment plants, pulp and paper industry, and many more.

1. Chemical Analysis: The chemical composition of TP304 stainless steel must be analyzed to check the presence of all the elements like Carbon, Manganese, Phosphorus, Sulphur, Silicon, Chromium, Nickel, and others mentioned in the standards.

2. Microstructure Analysis: The microstructure of the pipe can be analyzed under a microscope to check for any deviations from the required standards.

3. Dimensional Inspection: The TP304 Stainless Steel Pipe's dimension needs to be checked using precision measuring instruments to ensure that it conforms to the size and thickness required for the application.

4. Hydrostatic Testing: The pipe can be subjected to hydrostatic testing to verify its ability to withstand the specified pressure.

5. Mechanical Testing: The mechanical properties of the TP304 Stainless Steel Pipe, such as tensile strength, yield strength, and elongation, should be tested to ensure that they meet or exceed the specified requirements.

6. Non-Destructive Testing: The pipe can be subjected to non-destructive testing methods such as ultrasonic testing, dye penetrant testing, or radiographic testing to check for any internal defects that may affect its quality.

The surface of TP304 stainless steel pipe can vary depending on the manufacturing process and application requirements. Generally, the surface finish is classified into several types:

1. Mill finish - This is the raw surface finish of the pipe that is created during the manufacturing process. It is typically characterized by a rough and dull appearance.

2. Polished finish - This finish is achieved by using abrasive materials to polish the surface of the pipe to a smooth and shiny appearance. It is commonly used in decorative applications.

3. Brushed finish - This finish is created by brushing the surface of the pipe with a wire brush, creating a lined pattern that can hide scratches and wear over time.

4. Satin finish - This finish resembles a brushed finish, but the lines are finer and more uniform. It is often used in applications where a decorative but not reflective surface is desired.

5. Mirror finish - This finish is achieved by polishing the surface of the pipe to a highly reflective mirror-like appearance. It is commonly used in decorative and architectural applications.
