The force of steel pipe can only be called compressive bearing capacity, but can not be called compressive strength. The basic values ​​are: compressive strength of steel × pipe cross-sectional area, on this basis, to consider the overall stability factor of the compression member. The coefficient is obtained by the slenderness ratio of the compression member. The slenderness ratio is the calculated length of the compression member / radius of gyration of the section. If the standard size of the section, you can find the value of the gyration radius in the manual, or you have to calculate. According to past experience, slender than the average control in the 40 to 60 more economical. The above is just a brief introduction, want to know the specific calculation method, you can look at the "steel design specifications." This information source
Polyurethane Insulation Pipeline
Polyurethane Insulation Pipeline, full name: high-density polyethylene plastic outer protective polyurethane foam prefabricated direct-buried thermal insulation pipe, which is composed of a working steel pipe for conveying the medium, a polyurethane insulation layer, and a polyethylene plastic outer protective pipe, which are combined outwards through the equipment in turn.
