Abstract
The invention discloses a seamless steel tube for ships. The seamless steel tube comprises a tube body, the tube body comprises an outer tube main body and an inner tube main body, a plurality of radiating grooves are formed in the inner wall of the inner tube main body, a plurality of radiating grooves are formed in the outer wall of the outer tube main body, the multiple radiating grooves are evenly formed in parallel, and cross sections of the radiating grooves are square or rectangular. By means of the mode, the service life of the steel tube can be prolonged, and the seamless steel tube for the ships is simple in structure and low in manufacturing cost.
Description
Technical field
The present invention relates to seamless steel pipe field, particularly relate to a kind of Seamless Steel Tubes For Shipbuilding.
Background technique
Stainless-steel seamless pipe is common metallurgical fabricated metals, be applied in the market ships seawater pipeline, because of its special environmental requirement, must possess good corrosion resistance, pitting corrosion resistance and anti-stress performance, although the steel pipe of common material can meet the basic demand of ships seawater pipeline substantially, overall performance is unsatisfactory, easily produce spot corrosion and grain boundary corrosion, cause the reduction of steel pipe mechanical intensity and extension property, make steel pipe shorter working life, price is also comparatively expensive simultaneously.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of Seamless Steel Tubes For Shipbuilding, can improve the working life of steel pipe, simple in structure, low cost of manufacture.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of Seamless Steel Tubes For Shipbuilding is provided, comprise: body, described body comprises outer tube body and interior tube body, the inwall of described interior tube body offers a plurality of heat radiation grooves, the outer wall of described outer tube body offers a plurality of heat radiation grooves, between described a plurality of heat radiation grooves, is parallel evenly distributed, and the cross section of described heat radiation groove is square or rectangular.
In a preferred embodiment of the present invention, described body is integral type hollow tube, and the cross section of described body is rounded.
In a preferred embodiment of the present invention, between described interior tube body and outer tube body, be provided with separation layer, the thickness of described separation layer is 0.3-0.6mm.
In a preferred embodiment of the present invention, the inside of described interior tube body is provided with polishing layer, and the thickness of described polishing layer is 0.2-07mm.
In a preferred embodiment of the present invention, the outer wall of described outer tube body is provided with ion plating chromium nitride layer, and the thickness of described ion plating chromium nitride layer is 0.1-0.8mm.
The invention has the beneficial effects as follows: Seamless Steel Tubes For Shipbuilding of the present invention, the working life that can improve steel pipe, simple in structure, low cost of manufacture.
