1.What are seamless steel pipe used for?
Seamless steel pipe is perforated by the whole round steel, the surface of the steel pipe without weld, called seamless steel pipe.According to the production method, seamless steel pipe can be divided into hot rolled seamless steel pipe, cold rolled seamless steel pipe, cold drawn seamless steel pipe, extrusion seamless steel pipe.
Firstly: general purpose seamless steel pipe by ordinary carbon structural steel, low alloy structural steel or alloy structural steel rolling, the production is the most, mainly used for conveying fluid pipelines or structural parts.
Secondly: it is divided into three types of supply according to different uses: a. Supply according to chemical composition and mechanical properties; B. Supply according to mechanical properties; C. Supply according to water pressure test. Steel tubes supplied under class A and CLASS B, if used to withstand liquid pressure, are also subjected to hydrostatic test.
Finally: the seamless pipe of special use has boiler to use seamless pipe, chemical power to use, geology uses seamless steel pipe and oil to use seamless pipe to wait for a variety of. Mainly used for petroleum geology drilling pipe, petrochemical cracking pipe, boiler pipe, bearing pipe, automobile, tractor, aviation and other high-precision structural steel pipe. It is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile drive shaft, bicycle frame and steel scaffolding used in construction and other circular parts made of steel pipe, which can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, and has been widely used in the manufacture of steel pipe.
2.What is difference between seam and seamless pipe?
|performance||seamed steel pipe||seamless steel pipe|
|processing technic||The steel plate or strip is made by cutting, bending, welding and other processing processes||The tube blank is directly perforated and rolled|
|application||construction industry||The machine process the industry|
|appearance||There's a welding line, also called a weld bar||There's no sign of any welding|
|suffer from stress||weaker||stronger|
For the use of seam and seamless difference: seam pipe can generally bear the maximum use pressure in 20 kg, which is the safest range of use. It is generally used for water, gas, compressed air and other low-pressure fluids; Seamless tube can withstand super high pressure, of course, its wall thickness will also increase, which needs to be designed according to the pressure requirements. It is generally used for high pressure oil pipe, boiler pipe and other high temperature and high pressure equipment. There is also a seamless tube for structure, which depends on the design requirements. At present, there are some seamless welded steel tube tube, it is annealed on the weld, eliminate the residual stress of the weld, so that the weld and the base material is equal, the pressure range is basically equal to the seamless tube. Also consider using.
