Why Choose TP304 Pipe for Industrial Applications
TP304 is the most common grade of austenitic stainless steel used in the world. Its balanced chromium-nickel makeup gives it excellent corrosion resistance in moderately hostile settings.
You will have excellent weldability with no post-weld anneal required. The material is structurally stable in temperature ranges from cryogenic temperatures to 870°C intermittent service.
We integrate the latest cold drawing technology with precise solution annealing in our production process. This removes internal stress concentrations and provides dimensional tolerances of ± 0.05 mm.
The product range covers a variety of industries including chemical processing, food manufacturing, water treatment and architectural applications. Easy to install due to simplicity of manufacture and non-magnetic characteristics.

Superior Manufacturing Quality Control
Every product undergoes rigorous four-stage quality verification. Our vendor audit process begins with spectrographic analysis of virgin stainless steel materials, ensuring guaranteed nickel and chromium content.
During production, real-time dimensional monitoring tracks wall thickness consistency and outer diameter precision. Zero recycled materials enter our supply chain.
Independent testing protocols include tensile strength verification, yield point analysis, and elongation measurement. Flattening and flaring tests confirm formability characteristics.
Before shipment, comprehensive visual inspection verifies surface quality. Product marking accuracy and packaging integrity receive final validation alongside complete documentation assembly.
Third-party inspection services from SGS, BV, TÜV, DNV, and Lloyd's are readily available. You receive full material traceability with original mill certificates.
Customization Capabilities for Project-Specific Requirements
Our advanced processing facilities deliver tailored piping solutions matching your exact specifications. Precision laser cutting achieves complex hole patterns and slot configurations.
You can specify custom length cutting with minimal material waste. CNC pipe bending services accommodate radius requirements from 1.5D to 10D.
Threading services cover NPT, BSPT, and metric standards. End beveling prepares pipes for welding applications per ASME B16.25 requirements.
Surface finishing options extend from industrial sandblasted textures to 8K mirror polishing. Color PVD coating adds aesthetic value for architectural projects.
Minimum order quantity is flexible to accommodate big scale industrial projects or specialised small batch needs. Mixed container load optimises freight efficiency
Uses in critical industries
tp304 pipe is used in chemical processing plants for handling acids, alkalis and organic solvents. The material is resistant to pitting corrosion in chloride conditions up to 60 °C.
The smooth inside surface finish is an advantage for food and beverage manufacturing processes. This inhibits bacterial build-up while preserving product purity requirements.
These pipes are used in water treatment facilities for both drinking water distribution and wastewater treatment systems. NSF/ANSI 61 compliance guaranties public health.
The product is used in condensate systems and in auxiliary cooling circuits in power production plants. The material is stress fracture resistant during heat cycling.
The visual appearance of polished surfaces is a desirable feature for architectural applications such as handrails, structural columns, and ornamental installations. Weather resistance means zero maintenance expenditures.
Complete quality documentation and certification
Full EN 10204 3.1 Mill Test Certificates of chemical composition from ladle analysis are included with the shipping. The tensile strength, yield point and elongation values are confirmed by the results of mechanical property tests.
PMI reports validate the grade's legitimacy. Heat number traceability means that each pipe piece may be traced back to the original production data.
Dimensional inspection reports include measurements of the outside diameter, wall thickness and length. It has been ultrasonically tested for internal soundness and non-destructive testing certifications have been supplied.
Material Safety Data Sheets (MSDS) accompany shipments to ensure the compliance with regulations. The Certificate of Origin paperwork expedites the customs clearance process.
We are ISO 9001:2015 Certified which is proof of our dedication to quality management and consistency. Compliance to ISO 14001 and ISO 45001 shows environmental and safety responsibilities.
FAQ
Q：What are the standard industrial grading applications for this specific product product line?
A：This universal product is structurally ideal for commercial oil refinery grids, everyday chemical distribution lines, beverage production facilities, and water purification loops where medium corrosion risks exist.
Q：Does this product support custom sizing parameters beyond nominal warehouse schedules?
A：Yes, we offer flexible precision tailoring options covering custom outer diameters, variable wall requirements from SCH 5S up to heavy SCH 80S, and custom cuts up to 12 meters.
Q：What non-destructive testing (NDT) steps are taken to clear this pipe batch for shipment?
A：Every single piece passes through 100% automated internal eddy current scanning lines or high-pressure hydrostatic leakage verification to ensure zero wall flaws or molecular seepage risks.
Q: How does this austenitic grade behave at low temperatures in freezing lines?
A: The strong chromium-nickel mixture ensures higher cryogenic impact strength and microstructural ductility, thereby avoiding unexpected brittle fractures in severe cold-weather infrastructure installations.
Q：What tracking and certification records accompany my shipment of this product?
A：All shipments include a transparent Mill Test Certificate (MTC) conforming to EN 10204 3.1 criteria, capturing precise ladle chemical analysis heats and physical load test values.
