Stainless steel welding theoretical weight and weight table
Stainless steel welded pipe refers to the pipe made by rolling and welding stainless steel strips. It has high corrosion resistance, strength and excellent surface quality.
Characteristics
High corrosion resistance
The stainless steel material contains alloy elements such as chromium and nickel. It can form a dense oxide protective film on the surface of the steel pipe, preventing the invasion of external corrosive media. Therefore, it has excellent corrosion resistance and can be used for a long time in humid, acidic, alkaline and other corrosive environments.
High intensity
Stainless steel welded pipes have high tensile strength and yield strength, which enables them to withstand considerable pressure and external forces. They are not prone to deformation or rupture, thus ensuring the safety and reliability of the pipeline system.
Good surface quality
The surface of the welded pipe is smooth with low roughness. It is not prone to scaling or bacterial growth. It is not only aesthetically pleasing but also easy to clean and maintain. It is suitable for some occasions with high hygiene requirements, such as the food and pharmaceutical industries.
Good machinability
Stainless steel welded pipes are easy to be cut, bent and welded. They can be processed into various shapes and sizes of pipe fittings according to different engineering requirements, meeting the design requirements of various complex piping systems.
The theoretical calculation formula for stainless steel welding:
W = 0.02491 × S × (D - S)
Among them
W represents the weight of each meter of steel pipe (unit: kg/m)
S represents the wall thickness of the steel pipe (unit: mm)
D represents the outer diameter of the steel pipe (unit: mm)
For example, if there is a stainless steel welded pipe with an outer diameter of 50mm and a wall thickness of 3mm, its weight per meter is:
W = 0.02491 * 3 * (50 - 3)
= 0.02491 * 3 * 47
= 3.49251 kg/m
