Abstract
The invention discloses a combined seamless steel tube for pipelines. The combined seamless steel tube comprises a first semicircular steel tube and a second semicircular steel tube, wherein a first butting edge is arranged at each of the two ends of the first semicircular steel tube; a second butting edge is arranged at each of the two ends of the second semicircular steel tube; a convex surface matched with an E-shaped groove is formed at one end of each second butting edge; first locking devices are arranged at the other end of each first butting edge; a butting flange is arranged at one end of a pipeline formed by the first semicircular steel tube and the second semicircular steel tube; a welding layer is arranged on a coupling face of the pipeline; and a second locking device is arranged on the butting flange. According to the combined seamless steel tube for the pipelines, the semi-circular steel tubes are combined to form the integral steel tube, the steel tubes can constitute pipelines with optional lengths, not only is the material cost lowered, but also the transport is extremely convenient, and the transport cost is greatly lowered. Through all processing layers of the combined seamless steel tube, the pipelines can be waterproof and corrosion-resistant and are prolonged in service life.
Description
Technical field
The present invention relates to technique of pipe field, be specially a kind of pipeline combined type seamless steel pipe.
Background technique
The development of steel pipe's production technology start from the manufacturing rise of bicycle, 19th century younger oil exploitation, the manufacture of naval vessel, boiler, aircraft during Two World Wars, the manufacture of apparatus of thermo-electric power boiler after World War II, the development of chemical industry and the drilling of petroleum gas and transport etc., all effectively promote the development of Steel Tube Industries on kind, seed output and quality.Steel pipe not only for carrying fluid and powdery solid, exchange heat energy, manufacturing machine part and container, it or a kind of economic steel.Building structure rack, pillar and machinery mount is manufactured with steel pipe, can weight reduction, save metal 20 ~ 40%, and batch production mechanized construction can be realized.Manufacture highway bridge with steel pipe not only can save steel, simplify construction, and the area of stopping off can be greatly reduced, investment reduction and maintenance cost.So the steel of any other type all can not replace steel pipe completely, but steel pipe can replace part section bar and bar.The raising relation of steel pipe to the national economic development and human lives's quality is very large, outclass other steel.All steel pipe is be unable to do without from the daily apparatus of people, furniture, water supply and sewage, air feed, ventilation and heating facility to the exploitation of the manufacture of various agricultural machinery apparatus, underground resources, national defence and space flight firearms used, bullet, guided missile, rocket etc.Just because steel pipe and human lives, activity in production are inseparable, the production technology of Steel Tube Industries is not only developing rapidly, and weeds out the old and bring forth the new, and steel pipe's production occupies irreplaceable position in Iron And Steel Industry.
Delivery pipe now for the oxygen in oil, gas industry, water, oil all employ seamless steel pipe substantially, comparatively difficulty assembled in actual applications by existing seamless steel pipe, transport cumbersome, how easily transport use steel pipe becomes the problem that we face, we devise a kind of pipeline combined type seamless steel pipe for this reason, are used for solving the problem.
