100000 kilograms.
10?×100×100 = 10×10000 = 100000 (kg).
Steel pipe, steel with a hollow cross-section, the length of which is much greater than the diameter or circumference. According to the shape of the cross-section is divided into round, square, rectangular and shaped steel pipe. According to the material is divided into carbon structural steel pipe, low alloy structural steel pipe, alloy steel pipe and composite steel pipe.
According to the use is divided into transportation pipeline, engineering structure, thermal equipment, petrochemical industry, machinery manufacturing, geological drilling, high-pressure equipment, such as steel pipe. According to the production process is divided into seamless steel pipe and welded steel pipe, of which seamless steel pipe is divided into hot-rolled and cold-rolled two kinds, welded steel pipe is divided into straight seam welded steel pipe and spiral seam welded steel pipe.
Steel pipe use and classification
1. Piping pipe. Such as: water, gas pipe, seamless pipe for steam pipeline, oil pipeline, oil and gas trunk line pipe. Agricultural irrigation tap with pipe and sprinkler irrigation pipe, etc..
2. Thermal equipment pipe. Such as general boiler with boiling water pipe, superheated steam pipe, locomotive boiler with superheated pipe, large smoke pipe, small smoke pipe, arching brick pipe, and high temperature and high pressure boiler tube, etc..
3. Pipes for mechanical industry. Such as aviation structural tube (round tube, oval tube, flat oval tube), automobile half-axle tube, axle tube, automobile tractor structural tube, tractor oil cooler tube, square and rectangular tubes for agricultural machinery, transformer tubes, and bearing tubes and so on.
4. Petroleum and geological drilling pipe. Such as: oil drilling pipe, oil drilling rods, drilling jerks, oil pipes, oil casing and various pipe joints, geological drilling pipe (core pipe, casing, active drilling rods, drilling jerks, press hoops and pin joints, etc.).
5. Pipes for chemical industry. Such as: petroleum cracking pipe, chemical equipment heat exchanger and piping pipe, stainless acid pipe, fertilizer high-pressure pipe and pipe for transporting chemical media.
6. Pipes for other sectors. Such as: container tubes (high-pressure cylinder tubes and general container tubes), instrumentation tubes, watch case tubes, injection needles and their medical equipment tubes.
