It resists oxidation and corrosion in various environments making it suitable for a wide range of applications. Stainless steel 304 pipe has good mechanical properties providing strength & durability to withstand pressure and external forces and It is non porous, making it easy to clean and maintain sanitary conditions.
We are prominent SS 304 seamless pipe and tube supplier in India as per ASTM A312
Firstly, 304 stainless steel tubes are highly corrosion resistant which ensures that theymaintain their structural integrity even when exposed to corrosive substances. This property is important for preventing leaks and maintaining the purity of transported fluids.
This type of steel also has excellent heat resisting quality that allows the tubes to handle liquids and gases at high temperatures without any damage or deformity and the smooth internal surface of tubes minimizes friction contributing to a smooth flow.
We are leading stockist of 304 stainless steel welded pipe and tube in SCH 10, 20, 30, STD, 40, 40S, 60, XS as per ASME B36.19 standard
Stainless steel 304 pipe
304 stainless steel tube
ASTM A312 TP304 material
The NPS signifies the approximate inner diameter of pipe which is expressed in inches. NPS values mostly used for ASTM A312 TP304 material range from 1/8 inch to 30 inches with various intermediate sizes available.
Schedule number shows the wall thickness of pipe and determines its pressure bearing capacity. Schedule number is derived from a formula that relates the pipe’s outside diameter to its wall thickness. The commonly used schedule numbers for ASTM A312 TP304 are 5S, 10S, 40S, 80S and 160.
Our inventory of UNS S30400 ERW pipe usually exceeds 30000 tons. we supply ASTM A312 TP304 tube in size range from 1/8″ through 48″OD or custom

Schedule number of an SS 304 pipe directly affects its wall thickness. Higher schedule numbers mean thick walls whereas lower schedule numbers indicate thin walls. Selection of appropriate schedule number depends on the specific requirements of the application like pressure, temperature and structure.
A smooth and polished surface finish such as a mirror finish or satin finish makes it harder for dirt, debris, and contaminants to adhere to the surface. Thus, cleaning and maintenance become easier & require less effort and time.
A rough or textured surface finish such as a mill finish or brushed finish have a higher surface roughness which provides more areas for dirt and contaminants to stick to & makes them harder to clean.
- Chemical Composition Analysis: Determines the chemical composition of the SUS 304 pipe, verifying the presence & percentage of elements such as chromium, nickel, carbon and other alloying elements.
- Mechanical Properties Testing: Evaluates physical characteristics of the pipe including tensile strength, yield strength, elongation, hardness & impact resistance. These tests verify the mechanical strength and integrity of the pipe, ensuring it meets the required performance standards.
- Corrosion Resistance Testing: Evaluates the resistance of the pipe to various corrosive environments, such as saltwater, acids and chemicals. It helps determine the pipe’s ability to withstand corrosion & maintain its structural integrity over time.
- Pressure Testing: Assesses the ability of pipe to withstand internal pressure without leakage or failure. The pipe is subjected to hydraulic or pneumatic pressure to verify its pressure bearing capacity ensuring it meets the required safety standards for the intended application.
- Obtain quotes from multiple suppliers in India & compare their prices, delivery terms, and additional services offered. This allows you to choose the supplier offering the most competitive pricing without compromising on quality.
- Consider merging your orders or working with the supplier to optimize shipping & logistics. By reducing transportation costs, merging shipments or finding more cost effective shipping methods you can save money on overall expenses.
- Look for local Stainless Steel 304 pipe suppliers in India. Working with local suppliers can potentially save on transportation costs and lead to quicker delivery times.
