Stainless steel seamless theoretical weight and specification table

Stainless steel seamless pipes are long strips of steel with a hollow cross-section and no seams on the periphery.

The characteristics of stainless steel seamless pipes are:

Strong corrosion resistance

Stainless steel seamless pipes contain alloy elements such as chromium and nickel. They can form a dense oxide film on the surface, effectively preventing oxygen, water, and other substances from coming into contact with the metal substrate, thus having good corrosion resistance. They can resist the erosion of various chemical media, such as acids, alkalis, and salts, and are suitable for harsh working environments. 

High strength and toughness

With high strength and good toughness, it can withstand large pressure and impact forces, is unlikely to deform or break, and can meet the usage requirements of various engineering structures and equipment. 

Good surface quality

Its surface is smooth, with low roughness, and is not prone to scaling or bacterial growth. It is not only aesthetically pleasing but also conducive to the flow of the medium, reducing fluid resistance and lowering energy consumption. At the same time, it is also convenient for cleaning and maintenance. 

Good machinability

Easy to undergo cold processing and hot processing, such as bending, stamping, welding, etc., capable of being processed into various shapes and sizes of components to meet the requirements of different application scenarios. 

Good high-temperature and low-temperature resistance

It can maintain good strength and antioxidant properties even at high temperatures, and can be used in equipment such as high-temperature furnace tubes and heat exchangers; in low-temperature environments, it can also maintain good toughness and is not prone to brittle fracture, suitable for low-temperature storage and transportation fields. 

The formula for calculating the weight of seamless stainless steel pipe:

W = 0.02491 × S × (D - S) Among them:

W: The theoretical weight of each meter of steel pipe (in kilograms/meter)

S: The wall thickness of the steel pipe (in millimeters)

D: The outer diameter of the steel pipe (in millimeters) 

For example, suppose there is a seamless stainless steel pipe with an outer diameter D of 108mm and a wall thickness S of 4mm. Then the theoretical weight of each meter of the pipe is:

W = 0.02491 × 4 × (108 - 4)

= 0.02491 × 4 × 104

= 10.35328 kg/m

This formula is derived based on the density of the steel and the geometric dimensions of the pipe. The actual weight may vary due to the actual density of the steel and the tolerance of the pipe dimensions.
