Product Description

Seamless Stainless Steel Pipe is a type of pipe that is made from Stainless Steel without any welded joints or seams. This type of pipe is manufactured by heating a solid stainless steel billet to a high temperature and then piercing it with a mandrel to form a hollow tube. The resulting tube is then drawn through a series of dies to achieve the desired size and shape.

Seamless stainless steel pipe is preferred in applications where high strength, corrosion resistance, and durability are required. It is commonly used in industries such as oil and gas, chemical processing, and power generation. This type of pipe is also used in applications where cleanliness is critical, such as in the food and beverage industry.

One of the advantages of seamless stainless steel pipe is that it has a smooth interior surface, which reduces friction and allows for efficient flow of fluids or gases. It is also less prone to cracking and leaking compared to welded pipes, which can have weak spots at the welds.

Seamless stainless steel pipe is available in a variety of grades and sizes, depending on the application. Common grades include 304, 316, and 321 stainless steel. Sizes range from small diameter pipes used in instrumentation and control systems to large diameter pipes used in industrial applications.
