Details: Large diameter hot-rolled seamless steel pipe definition

Large-diameter hot-rolled seamless steel pipe diameter of 219 in the above, large-diameter hot-rolled seamless steel pipe width, thickness, length, angle, and edge lines are not required too accurate, generally appear on the difference. Hot-rolled seamless pipe sub-ordinary pipe, low and medium pressure boiler pipe, high pressure boiler pipe, alloy steel pipe, stainless steel pipe, oil cracking pipe, pipe and other geological steel pipe. Large-diameter seamless steel pipe parts in the heating and cooling process, due to the surface and the heart of the cooling rate and time inconsistent, the formation of temperature, it will lead to uneven volume expansion and contraction and stress, that thermal stress. Large-diameter hot-rolled seamless steel pipe can be used as a pipe for conveying fluid to transport oil, natural gas, gas, water and some solid material pipes. It can also be used for the construction support, steel structure and pile foundation. Understand my company more knowledge of seamless steel pipe to:

Reflective Glass(coated glass),also known as heat-reflective glass(solar-control coated glass),is plating on high-quality Float Glass surface with a vacuum magnetron sputtering ws0ay to multi-layer metal or compounds coating. It can control the direct solar radiation reflection, transmittance and absorption by the ratio to reach the needed reflective color. The development of architectural aesthetics arouses high requirements to the architectural glass on lighting with appropriate sight shielding, energy-saving with decoration, which could be realized by reflective glass.
