Exhibition and the drilling of petroleum gas and transport etc., all effectively promote hair of the Steel Tube Industries in kind, yield and quality
Exhibition.Steel pipe can be divided into two major classes by production method：Seamless steel pipe and seamed steel pipe, seamed steel pipe are referred to as steel pipes with straight.Steel pipe
It is applied not only to trandfer fluid and powdery solid, exchanges heat energy, manufacture machine components and container, it or a kind of economic steel.With
Steel pipe manufacture building structure rack, pillar and machinery mount, can mitigate weight, save metal 20~40%, and can realize work
Factory's mechanized construction.Steel, simplified construction, investment reduction and maintenance cost can be saved by manufacturing highway bridge with steel pipe.
Special-shaped seamless steel pipe is the general name of the seamless steel pipe of other cross sectional shapes in addition to pipe.By steel tube section shape
The different wall thickness special-shaped seamless steel pipes such as can be divided into again of shape size（Code name is D）, the wall thickness special-shaped seamless steel pipe such as not（Code name is
BD）, variable diameters special-shaped seamless steel pipe（Code name is BJ）.Special-shaped seamless steel pipe is widely used in various structural members, instrument and machinery zero
Part.Compared with pipe, shape tube typically has larger the moment of inertia and modulus of section, there is larger bending resistance anti-twisting property, can
To mitigate construction weight, saving steel significantly.Shape tube is usually to be distinguished according to disconnected section, by can be divided into for material again
Seamless steel pipe shape tube, aluminium alloy shaped-tube, plastic shaped pipe.Wherein, steel pipe shape tube can be divided into oval steel tubes, three
Angular steel tubes, hexagon steel tubes, rhombus steel tubes, octagonal steel tubes, semicircle deformed steel circle, inequilateral
Hexagon steel tubes, five valves are quincunx steel tubes, lenticular steel tubes, double concave steel tubes, melon seeds shape deformed steel
Pipe, conical steel tubes, corrugated steel tubes etc..The convenient lock used at present under the particular surroundings such as train, aircraft is all
It is using the lock core of inner core abnormity, just can be easily opened with the use of with special-shaped inner core identical key.But present system
Make complex process, and efficiency is low, wear more serious after such lock core long-term use, be not easy to repair, integral replacing into
This height, and when unlocking, key and the sound that lock core friction is sent are larger, especially in the place that needs are kept quite, noise
Easily influence other people greatly.
