It is also known as welding long rail line, which is a kind of line that welded normal rails without rail seam. The welding rail is not less than 200 meters long, and the actual application is usually 800~1000 meters or more. The long track is laid in the specified temperature range and fixed on the pillow. The long rail ends with a rail joint, while the middle part cannot scale up and down with the temperature. Therefore, there will be a great temperature pressure in the middle of the rail during the summer, which will produce a great temperature tension in winter. The greatest pressure on the rail and tension according to the years of rail laying and the highest temperature and minimum temperature calculation, rail tracks the maximum pressure should not cause to drum up by maximum tension should not cause rail fracture
For years, car and motorcycle enthusiasts are already replacing their standard steel wheels with larger alloy wheels and hubcaps. At a glance, it's not hard to see why these alloy wheels have grown to be very popular. Not only do they supply a smoother ride than regular steel wheels, but also they look flashier and invite vehicles to stand out.
