Standard Aspect	Details
Manufacturing Process	These pipes are typically produced through hot - rolling or cold - drawing. Hot - rolling is efficient for large - scale production and creating larger - diameter pipes, while cold - drawing offers higher precision in dimensions, especially for smaller - diameter pipes. The seamless nature eliminates potential weak points from weld seams, ensuring enhanced durability.
Dimensional Tolerances	Diameter tolerances vary based on the pipe size. For larger diameters (e.g., > 100 mm), the tolerance is often around ±1% of the nominal diameter. Smaller diameters may have a more precise tolerance, sometimes as low as ±0.5 mm. Wall thickness tolerances are generally within ±10% of the specified thickness, but can be tightened for applications with strict requirements.
Testing Requirements	Tubes are subjected to a series of non - destructive and destructive tests. Non - destructive tests include hydrostatic testing to check for leaks under pressure and ultrasonic testing to detect internal flaws. Destructive tests such as tensile, impact, and bend tests are carried out to evaluate mechanical properties like strength, toughness, and formability.

Grade	Applications
Tp310s	- High - temperature applications such as furnace parts, kilns, and incinerators due to its excellent high - temperature strength and oxidation resistance. - Aerospace components where exposure to extreme heat is common.
Tp316	- Chemical industry, especially in environments with chloride - containing substances, as it has outstanding corrosion resistance. - Food and pharmaceutical industries for its hygienic properties and ease of cleaning. - Marine applications because of its resistance to seawater corrosion.
Tp304	- General - purpose applications in construction, architecture, and household appliances due to its good corrosion resistance and relatively lower cost. - Heat exchangers in HVAC systems. - Dairy and beverage processing equipment.

Grade	Advantages	Disadvantages
Tp310s	- Exceptional high - temperature performance, maintaining strength and integrity at elevated temperatures. - Good resistance to oxidation and carburization.	- Higher cost compared to Tp316 and Tp304 due to the high content of nickel and chromium. - Machining can be more challenging due to its alloy composition.
Tp316	- Superior corrosion resistance, particularly against chloride - induced corrosion. - Good formability and weldability, facilitating fabrication. - High strength - to - weight ratio.	- Costlier than some standard carbon steel pipes. - Susceptible to stress corrosion cracking in specific aggressive environments if not appropriately designed.
Tp304	- Widely available and relatively cost - effective among stainless steel grades. - Good corrosion resistance for general - purpose applications. - High ductility, allowing for easy forming.	- Lower corrosion resistance compared to Tp316, especially in harsh chemical environments. - Less suitable for high - temperature applications compared to Tp310s.
