304 Stainless Steel Welded Pipes are a type of metal piping that is made from a combination of chromium and nickel. These pipes are durable, corrosion resistant, and heat resistant, making them an ideal choice for use in a variety of industrial and commercial applications.
The welded construction of 304 stainless steel welded pipes provide strength and leak-proof joints that are suitable for use in high-pressure environments. The combination of corrosion resistance and strength makes these pipes a great choice for long-term use.
The application of 304 stainless steel welded pipe is diverse , being commonly used in machinery , architectural , chemical ,food and beverage and cryogenic industries
In machinery, it is used in components such as valves, pumps, and fasteners.
Architecturally, it is used for cladding and handrails, as well as for structural frameworks.
In chemical industries, it is used in process piping systems and heat exchangers.
In the food and beverage industry, it is used for its corrosion resistance and non-contamination properties.
Lastly, in the cryogenic industry, 304 stainless steel welded pipe is used for its strength and durability in extreme temperatures.
304 and 316 stainless steel are both popular grades of stainless steel, however, there are important distinctions between them.
On a chemical level, 304 stainless steel contains 18% chromium and 8% nickel while 316 stainless steel contains 16% chromium, 10% nickel, and 2% molybdenum. This difference in chemical composition gives 316 stainless steel superior corrosion resistance compared to 304 stainless steel.
Price-wise, 316 stainless steel is usually more expensive than 304 stainless steel. However, this difference in price is usually minimal and the cost of corrosion prevention must also be taken into account.
In terms of usage, 304 stainless steel is typically used for kitchen sinks, medical equipment, and architectural applications while 316 stainless steel is often used for chemical processing equipment, marine applications, and in the food and beverage industry.

304 stainless steel welded pipe is the most popular product in Foshan Vinmay Stainless Steel Co.,ltd. Vinmay's 304 stainless steel pipe stands out from the competition due to its superior raw material, thickness and outer diameter, outer surface, welded line, and mechanical properties.
Analysis of raw materials used for the production of stainless steel welded pipes is essential. Vinmay's commitment to high-quality raw materials ensures that their 304 stainless steel welded pipes are reliable and durable.
All of the raw material in Vinmay are from TISCO, BAOSTEEL, TSINGSHAN and other high quality steel supply refining furnace materials, which can make sure a high stability and corrosion resistance to all of our products. In addition, we can provide the quality inspection report of raw materials.
Thickness and Outer Diameter
Stainless steel welded pipes are produced according to international standards of tolerance, and have a wide range of thickness and outer diameter variations. This makes them ideal for use in fittings assemblies, as they are easy to work with and have a reliable degree of accuracy.
This allows for the construction of complex, interdependent parts and structures in a safe and efficient manner.
The outer surface of a stainless steel welded pipe is of great importance. All of the stainless steel welded pipe from Vinmay are Free from press point, scratches, black spot. And the mirror finish of 600 grit stainless steel pipe are close to Taiwanese and Italian producers， what’s more the outside welded lines of our stainless steel welded pipe are invisible
Welded lines are a critical component of stainless steel pipes, requiring precision in their execution. Fully T.I.G welding is used to ensure that the weld bead has a maximum height of 0.2mm, which enables the pipe to be easily bent to the desired shape.
Flaring, flattening and flange testings allow us to follow standards: EN 10217-7， EN 10312, DIN11850（EN10357) , ASTM 249/269 and 270
Pipe Inner Surface
The inner surface of welded stainless steel pipe is of great importance to the overall quality of the pipe. All of the pipe from Vinmay are Removing the inside bead of the welded area reduces the roughness of the surface below 1.6 Ra. With further polishing of the inside surface, the roughness can be further decreased to a range of 0.4-0.8 Ra. And what’s more All of our tubes are in100% inside cleaning ( ultrasonic wave and wipe)
