Usually the storage method: pipe for the spiral welded pipe unit tube diameter with the letter D to indicate, followed by additional external diameter scale and wall thickness, such as the outer diameter of 105 seamless steel pipe, wall thickness of 6MM, with D107 * 5 Indicating that the plastic pipe also uses the outer diameter to indicate, such as De63, other such as reinforced concrete pipe, cast iron pipe, galvanized pipe and other optional DN show that in the planning drawings are usually selected nominal diameter to indicate that the nominal diameter is for planning production and repair The convenience of man-made delineation of a scale, but also more than the nominal diameter, is the pipe (perhaps the pipe) the standard name.
      Spiral welded pipe equipment between the stacking and stacking should be left in a certain channel, check the width of the road is usually about 0.5m, the width of the income and expenditure channel depends on the size and transport machinery, usually 1.5 to 2m. Spiral steel pipe stacking height, manual work does not exceed 1.2m, mechanical work does not exceed 1.5m, stacking width does not exceed 2.5m. Such as spiral welded pipe unit steel pipe in the open space, must be in the spiral pipe below the wooden mat or stone, etc., and the stack should be slightly inclined to facilitate drainage, and pay attention to the steel pipe is not straight, to avoid bending deformation of steel. Spiral welded pipe equipment, the height of the bottom of the pad According to the details, if the warehouse for the sun on the concrete floor, the pad height of 0.1m can be; if the mud, to be pad 0.2 to 0.5m. If in the open storage, the cement floor should be high in the 0.3 to 0.5m, the sand on the pad should be high in the 0.5 to 0.7m. The strength of the spiral welded pipe unit is usually higher than that of the straight seam welded pipe, and the pipe with larger diameter can be produced by the narrow billet. The pipe with the same width can also be produced with the same width. However, compared with the same length of the straight pipe, the weld length of 40 to 100%, and the production rate is low. After cutting into a single steel pipe, the first three batches of steel pipe to conduct a rigorous first check system, see the weld mechanical properties, chemical composition, melting conditions, steel pipe surface quality and through the nondestructive testing and maintenance, to ensure that after the pipe technology , The ability to put into production. Spiral welded pipe equipment production technology frugal, high production efficiency, low cost, carry out faster.
