Seamless Steel Pipe Storage What Precautions

Building materials industry, the development of a variety of pipe are not the same, because of their different characteristics, the connection between the pipe there is a certain distance. Square tube, which is one of the many pipe materials in the building materials industry. Is formed after the strip through the treatment, Seamless steel pipe the various characteristics of steel pipe needs to understand, but the building materials industry, the development of a variety of pipe is not the same, because of their different characteristics, the pipe between the link there is a certain distance. Square tube, which is one of the many pipe materials in the building materials industry. Is formed after the strip through the treatment, the various characteristics of the steel pipe needs to understand, but exactly because of steel and other raw materials, the storage of steel pipe is the demand for specific conditions.

In the storage of seamless steel pipe, the primary needs of the appropriate selection of places, we need to think about many external elements, the corrosion of steel pipe, etc., so the place must be clean, dry and ventilated place where harmful gases are present, Can not be presented, weeds and other debris to be promptly removed, Seamless steel pipe to keep the outer surface of steel clean. If the warehouse in the acid-base salt easily react with the steel pipe so that corrosion of steel, so try to be able to cut open, do not let it touch. In addition, if for those on the higher price of metal, can think into the warehouse very good reservation.

Seamless pipe pressure is how to calculate

The following we select a practical case to illustrate DN = 10MM, the wall thickness of 3mm set the tensile strength of the material σ, the pressure P, the pipe diameter D; pipe wall thickness δ = (P * D) / (2 * σ / S) where S is the safety factor;

Because P is less than 7MPa, S choose S = 8; P less than 17.5MPa, S choose S = 6; P greater than 17.5MPa, S choose S = 4; we choose the safety factor S = 6; , So the pipe can withstand the pressure P = (2 * σ / S * δ) / D = (2 * 410/6 * 3) / (10 + 6) = 26.25MPa> set 17.5 so the safety factor to take S = 4 Therefore, the pipe can withstand the pressure P = (2 * σ / S * δ) / D = (2 * 410/4 * 3) / (10 +6) = 39.375MPa According to this formula you can easily calculate a variety of Thick-walled seamless steel pipe pressure capacity.
