Products Description
TP304 Stainless Steel Tube is an austenitic stainless steel tube that meets the ASTM A213 standard and is widely used in heat exchangers, boilers, chemical equipment, food machinery, and other fields.
Advantages
Corrosion Resistance
By controlling the chromium content to between 18%-20% and the nickel content to between 8%-11%, combined with a precision pickling process, the pipe maintains long-term corrosion resistance in weak acid and alkaline environments.
Suitable Mechanical Properties
Through solution treatment and cold working processes, this product achieves a stable tensile strength of over 515 MPa and a yield strength of 205 MPa. Combined with an elongation of 35%, it exhibits excellent deformation resistance under moderate stress conditions.
Uniform Internal and External Hardness
Through solution treatment and automated hardness testing equipment, the Brinell hardness is maintained within 192 HBW, ensuring uniform hardness of the internal and external walls, preventing cracking or premature failure due to localized hardening during use.
High Dimensional Accuracy and Efficient Piping
Using a cold-drawn forming process and multi-stage dimensional inspection, the pipe's outer diameter can be accurately controlled to within ±0.2 mm, ensuring precise on-site welding.
Applications
For fluid transport in food processing equipment
ASTM A213 TP304 Stainless Steel Tube is commonly used in piping systems within food processing equipment to transport liquid raw materials or cleaning media. Its corrosion resistance and surface cleanliness ensure the purity of the media and meet food-grade safety requirements.
For clean piping systems in the pharmaceutical industry
This product is widely used in clean conveying systems in pharmaceutical production lines to transport water for injection, purified water, and other process fluids. Polishing and pickling improve the internal surface finish, reduce the risk of bacterial residue, and meet GMP requirements.
For heat transfer structures in heat exchange equipment
ASTM A213 TP304 Stainless Steel Tube serves as a heat transfer element in heat exchangers, transferring fluid heat energy. Its dimensional stability and excellent thermal conductivity improve heat transfer efficiency and are suitable for HVAC, condensing, and steam systems.
Corrosion-resistant piping in the light chemical industry
In light chemical plants, this stainless steel pipe is used to construct low-pressure corrosive media pipelines, primarily for conveying weak acids, alcohols, or cleaning agents. Its neutral corrosion resistance ensures stable equipment operation and extends system life.

FAQ
Q: 1. What international standards does TP304 stainless steel pipe comply with?
A: Common implementation standards for TP304 stainless steel pipe include ASTM A312 (seamless and welded austenitic stainless steel pipe for high temperature service), ASTM A213 (seamless pipe for boilers, superheaters, and heat exchangers), etc. In addition, it can also meet EN, DIN, JIS, and other standards according to customer needs.
Q: 2. Is TP304 stainless steel pipe magnetic?
A: TP304 is an austenitic stainless steel, which is theoretically non-magnetic, but a small amount of ferrite structure may be introduced after cold working or welding, showing slight magnetism. This is normal and does not affect its performance.
Q: 3. Can non-destructive testing (NDT) be performed?
A: Yes. According to application requirements, TP304 stainless steel pipe can be subjected to non-destructive testing methods such as ultrasonic testing, eddy current testing, and X-ray testing to ensure that there are no cracks, inclusions, or other defects inside the product.
Q: 4. Can the length of the pipe be customized?
A: Yes. In addition to the conventional 6-meter or 12-meter fixed length, it can be cut to length according to customer needs, and the cuts are kept smooth and burr-free for easy on-site installation.
Q: 5. What are the surface treatment methods for TP304 stainless steel pipes?
A: Common surface treatments include pickling, polishing, sandblasting, mechanical grinding, and BA (bright annealing). Different treatment methods are suitable for different fields, such as polishing for the food and pharmaceutical industry, and pickling for industrial purposes.
Q: 6. What is the difference between TP304 and 304L stainless steel pipes?
A: The main difference lies in the carbon content. 304L has a lower carbon content (≤0.03%), which is suitable for occasions where welding is required and the risk of intergranular corrosion is reduced. TP304 has a more balanced performance and lower cost when there are no special requirements.
Q: 7. Is TP304 stainless steel pipe suitable for underground laying?
A: TP304 can be used for underground laying if there is good drainage or appropriate external anti-corrosion protection measures (such as PE casing and epoxy resin coating). However, it is recommended to use more corrosion-resistant materials (such as 316) in chloride-containing soil or a humid environment.
Q: 8. What factory inspections will be carried out before product delivery?
A: Usually including chemical composition analysis, mechanical property testing (tensile strength, yield, elongation), dimensional measurement, water pressure testing, appearance inspection, etc., and third-party inspection reports (such as SGS, BV) can also be provided according to contract requirements.
Q: 9. How to store TP304 stainless steel pipes correctly?
A: It should be avoided from mixing with other metals such as carbon steel. It is recommended to place it in a dry and ventilated place, away from acid and alkali chemicals, and use wooden pallets or plastic cushions to isolate it to prevent scratches or rust.
Q: 10. How to prevent pipe damage during transportation?
A: During transportation, special steel pipe packaging (such as waterproof paper + plastic cloth + wooden box or steel frame) should be used, and the end protection caps should be fixed to avoid collision, bending, and scratches during loading and unloading to ensure the safe arrival of the product.
