Characteristics and properties of stainless steel tube:
high plasticity and viscosity;
excellent resistance to corrosion processes, due to which the operation of rolled products with highly aggressive carriers is
allowed;
the possibility of using stainless steel pipes in a wide temperature range;
resistance to vibrations and mechanical influences;
bactericidal properties, allowing the use of products in the food industry;
long service life;
relatively light weight.
Seamless round stainless pipes, due to the absence of seams, are characterized by high consumer properties,
offering consumers valuable qualities:
when operating in main pipelines - absolute tightness of the pipe;
high resistance to corrosion;
the ability of the product to be deformed, while the mechanical properties of the surface are not violated;
long period of operation.
Stainless Steel Welded Round Tubes also have all of the above properties, but with the addition of a small cost that
makes them very popular in low cost projects such as general purpose piping systems
Application of stainless steel pipe:
The main areas of application of stainless steel pipes are the laying of hydraulic pipelines and the creation of pneumatic
machine systems, heating systems. Stainless steel pipelines can be laid both inside and outside buildings. Various types
of pipes are used to organize the supply of cold or hot water, as well as other liquids. Such pipelines do not have any effect
on the composition of the liquid and are suitable for operation in the food industry. They are indispensable in equipping
facades and interiors with stair railings. Less commonly, stainless pipes are used to strengthen and give strength to
any structures, buildings and structures, as well as in heating systems at thermal power plants.
Large-diameter pipes are used in the laying of gas and oil pipelines, the creation of water, sewer and heating networks.
The creation of industrial and engineering communications is also accompanied by the use of stainless steel pipes of large
diameter. Thick walls ensure the strength of the pipes when transporting raw materials under high pressure. The attractive
appearance of polished pipes makes them indispensable when equipping buildings with stair railings, racks and other elements.
Stainless steel pipe Duplex 2205
Duplex 2205 Pipe is made up of a duplex steel material that is corrosion resistant, strong and is nitrogen enhanced. The duplex
products have dual metallurgic structures as austenitic and ferritic in their microstructure. Therefore they combine the wealth of
both types of steels.The Duplex S31803 Pipe material has chromium, nickel, manganese, molybdenum, nitrogen phosphorus
and carbon in its composition.The Duplex Steel Pipe and Duplex UNS S32205 Pipe can come in either as welded pipes or
seamless pipes.
