In addition, the overhead pipe body 2 is made of S30408 stainless steel, and S30408 corresponds to the national brand: 06Cr19Ni10, belonging to the austenitic stainless steel group, is a versatile stainless steel material, and is widely used for equipment and parts requiring good balance of properties due to its corrosion resistance and formability. In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain 12% or more of chromium. 06Cr19Ni10 is a stainless steel and a heat resistant steel which are most widely used. Can be used for food production equipment, common chemical equipment, nuclear energy and the like. S30408 when used in a tap water pipeline, the service life of the tap water pipeline can be remarkably prolonged, and the longest service life can reach 70 years. Because the body 2 of the overhead pipe is in a severe outdoor environment for a long time and has high requirements on corrosion resistance and rust prevention, the S30408 steel pipe can not only prolong the service life of the water supply overhead pipe, but also reduce the subsequent maintenance cost.
The maximum allowable span of the body of the overhead pipe is calculated and controlled simultaneously according to two conditions of strength and rigidity, namely the maximum allowable span is calculated by the following two formulas:
in the formula: lmax-maximum allowable span (m) of the pipe body of the overhead pipe;
q-calculating load (N/m) of the pipe body of the overhead pipe in unit;
w is bending moment resistance (cm3) of the section of the overhead pipe body;
phi represents the transverse welding seam coefficient of the body of the overhead pipe;
sigma-allowable stress of stainless steel tube in hot state (N/mm2)
E-stainless steel elastic modulus;
i, inertia moment of the section of the body of the overhead pipe;
i-water discharging gradient of the pipe body of the overhead pipe.
The pipe body 2 of the overhead pipe in the embodiment is made of the S30408 stainless steel material, and compared with carbon steel, the allowable stress and the elastic modulus of the S30408 stainless steel are consistent, so that the maximum allowable span of the S30408 stainless steel and the carbon steel are the same. The maximum allowable span of the small-diameter pipeline is calculated and compared, the difference between the maximum allowable span and the maximum allowable span of the small-diameter pipeline is less than 2 percent, and the table is shown in the specification. Therefore, under the condition that the span of the body 2 of the overhead pipe is not changed, it is feasible to change the material of the body 2 of the overhead pipe from carbon steel pipe to stainless steel.
The implementation principle of the stainless steel river-crossing overhead pipe structure of the embodiment of the application is as follows: the overhead pipe body 2 is made of S30408 stainless steel, has the advantages of high strength, corrosion resistance and long service life, and overcomes the defect of short service life of the carbon steel pipe, in addition, the overhead pipe body 2 is detachably mounted by the connecting component 3, so that maintenance personnel can replace and maintain the overhead pipe body 2 conveniently, and the maintenance and replacement cost is reduced.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
