Abstract
The invention discloses a transformer oil conveying supporting special-shaped steel pipe capable of meeting the environmental requirements and process requirements for transformer oil conveying supporting. The special-shaped steel pipe is a seamless steel pipe, the section of an inner wall of the seamless steel pipe is roughly rectangular, and the section of an outer wall of the seamless steel pipe is also roughly rectangular. The special-shaped steel pipe has the advantages that the effect is extremely good by adopting the seamless steel pipe to support transformer oil conveying because the seamless steel pipe is high in strength, strong in bend resistance, excellent in corrosion resistance and good in sealing effect and the like.
Description
Technical field
The present invention relates to a kind of transformer oil transportation support steel tubes.
Background technique
Seamless steel tube production is one of national pillar industry, and along with development and national economy, the demand of seamless steel pipe is the trend of cumulative year after year.Seamless steel pipe is for the manufacture of structural members such as automobile, train, aircraft, steamer, space guns, and component of machine such as agricultural, mine, engineering, electrician, weaving, military project, seamless steel pipe still is that the application of military industry field is all very extensive at civil area.Because the circular section steel pipe is stressed more even when bearing inside or outer radial pressure, so obtain a large amount of uses, but in many cases, the circular section steel pipe can not satisfy the specific usage requirement of structure member or mechanical part, therefore need extraordinary steel tubes come manufacturing structure parts or mechanical part, improve stock utilization and save material and simplify production technology, shorten purposes such as manufacture cycle to reach.
Two, the defective of pipe finds expression in
1, steel tubing in different shapes is compared with pipe, the sectional shape of pipe is limited, has certain narrow limitation, can't be used for some specified conditions and environment, and steel tubing in different shapes has more economic cross section advantage, adapt to the particularity of service condition, can save metal, improve stock utilization, simplify manufacturing process, raise labour productivity;
2, steel tubing in different shapes is compared with pipe, and steel tubing in different shapes all is better than pipe in overall appearance moulding and the design concept of product;
3, steel tubing in different shapes is compared with pipe, is satisfying under the conditions such as equal usability, and steel tubing in different shapes can alleviate structure weight greatly;
4, moment of inertia and the section modulus of pipe are less, and under the condition that is subjected to plane bending and distortion, it is big to be not so good as steel tubes resistance to flexure and anti-twist ability;
5, pipe and the steel tubing in different shapes of the same length of side and diameter, steel tubing in different shapes bearing capacity and shock resistance are better;
More than multiple reason limited service condition and the scope of pipe, under some particular surroundingss and condition, so adopt steel tubing in different shapes to make structure member or mechanical part.For example the transformer oil transportation is supported and with steel pipe part requirement is had the intensity height, service conditions such as counter-bending ability is strong, excellent corrosion resistance, sealing are effective, but also need possess complicated shape and structure, therefore just can not adopt steel tubing in different shapes to make with pipe.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and can satisfy the environmental requirement of transformer oil transportation support usefulness and the transformer oil transportation support steel tubes of technological requirement.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of transformer oil transportation is supported and used steel tubes, described steel tubes is seamless steel pipe, and the cross section of the inwall of seamless steel pipe is roughly rectangular, and the cross section of its outer wall is also roughly rectangular.
Arc transition between the described seamless steel pipe adjacent inner wall, transition arc radius are r; Also be arc transition between the adjacent outer wall, transition arc radius is R.
The long L of the rectangle in described seamless steel pipe internal wall cross section, wide M; The long K of the rectangle in outer wall cross section, wide Q, wherein the unit of r, R, L, M, K, Q is mm, and satisfies 10 (π r)
2=L
2+ M
2, R=r, K-L=Q-M.
The length of the rectangle in described seamless steel pipe internal wall cross section and wide equating; The length of the rectangle in outer wall cross section and wide equating.
The material of described seamless steel pipe is Q345C, and through normalizing heat treatment.
The invention has the beneficial effects as follows: the seamless steel pipe of employing said structure is used as the support of transformer oil transportation, and effect is very good, because the seamless steel pipe of said structure has the intensity height, counter-bending ability is strong, excellent corrosion resistance, advantage such as sealing is effective, and satisfy 10 (π r)
2=L
2+ M
2, R=r during the requiring of K-L=Q-M, can better embody the use advantage of seamless steel pipe.
Description of drawings
Fig. 1 is that the sectional view with steel tubes is supported in transformer oil transportation of the present invention.
Among the figure: 1, inwall, 2, outer wall.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, transformer oil transportation of the present invention is supported and used steel tubes, described steel tubes is that material is Q345C, and through the heat treated seamless steel pipe of normalizing, and the cross section of the inwall 1 of seamless steel pipe is roughly rectangular, and the cross section of its outer wall 2 is also roughly rectangular.Arc transition between the described seamless steel pipe adjacent inner wall 1, transition arc radius are r; Also be arc transition between the adjacent outer wall 2, transition arc radius is R.The long L of the rectangle in described seamless steel pipe internal wall 1 cross section, wide M; The long K of the rectangle in outer wall 2 cross sections, wide Q, wherein the unit of r, R, L, M, K, Q is mm, and satisfies 10 (π r)
2=L
2+ M
2, R=r, K-L=Q-M, this makes the performance of seamless steel pipe further be improved.In actual production, the length of the rectangle in described seamless steel pipe internal wall 1 cross section and wide can equating; The length of the rectangle in outer wall 2 cross sections and widely also can equate.
Advantage of the present invention is: the seamless steel pipe of said structure has the intensity height, and counter-bending ability is strong, excellent corrosion resistance, and advantage such as sealing is effective, fairly obvious as transformer oil transportation support tube effect.
