On the strength of stronger intensity for pipe pile

The outer diameter of the thick-walled tube coil steel pipe pile by size and thickness of the letter D followed by additional outer diameter of, for example, represented by the 105 seamless steel pipe wall thickness of 6mm diameter, and D107 * 5, said tube plastics can also use the outer diameter expressed as De63, others such as reinforced concrete pipe, cast iron pipe, galvanized pipe, etc. using DN said that the engineering drawings nominal diameter is generally indicated with a nominal diameter of design and implementation, and maintenance of human-driven delimit one kind of scale is bigger nominal diameter pipe (or pipes) canonical name.

Open spiral steel pipe pile, it is necessary to prevent the spiral steel pad beneath wooden or stone, and if the battery on a flat surface should be tilted slightly to promote drainage, and notify steel, steel pipes, to avoid bending
Strength steel coil thickness is usually higher than in the large-diameter pipe joints straight, it is possible to reduce the production of large diameter pipe billet pipe high, but you can also use the same width of the billet production of different pipe diameters. However, compared to the same length of straight seam pipe, 40-100% of the weld length, and reduced productivity. In a single pipe cutting steel, each consisting of three steel rail head strict control system, control the mechanical properties of welding, chemical composition, the state of integration, test tubes and maintain the quality of the steel surface by non-destructive to ensure that the transmission through the tube in order to put the process of post-production. Simple tube, high production efficiency, low cost, rapid development of the thick spiral production process.
Between the stack has a thick-walled reactors and certain channels remain spiral, the width of the road checks are often dependent on access to materials and transport machinery about the size of 0.5μm, width, they are generally in the 1.5 to 2M
Spiral steel stacking height, 1.2 meters in manual work, mechanical work is no longer than 1.5 meters, stacked no more than 2.5 meters wide,
The height of the cushion and the thicker walls of a detail of the bottom of the base spiral steel chimney, if the warehouse sun concrete floor, can be upgraded to a height of 0.1μm; if mud, is upgraded from 0.2 to 0.5 microns. If stored in the open air, concrete floor booster should be about 0.3 to 0.5 microns, recall the sediment surface should be 0.5 to 0.7 micron.
Now we explain the spiral pile and classification standard features, we want to help you understand the helical coil and standard classifications: with spiral submerged arc welded pipe (SY5036-83) pressurized fluid delivery mainly used for oil transport, gas pipeline; with spiral seam high frequency welded steel pipe (SY5038-83), hydraulic oil is about high-frequency spiral welded steel pipe welding method of transmitting high frequency pressure fluid delivery. High pressure steel, plastic, and easy welding and machining molding; liquid delivery spiral submerged arc welded pipe (SY5037-83) general low pressure, using double-sided automatic submerged arc welded into a single-sided or for water, gas, air and steam low pressure discharge the legal system of the liquid SAW pipe
Features: large-diameter pipe production process straight seam steel pipe pile simple, high production efficiency, low cost, rapid development. Strength steel coil thickness is usually higher than in the large-diameter pipe joints straight, it is possible to reduce the production of large diameter pipe billet pipe high, but you can also use the same width of the billet production of different pipe diameters. However, with respect to the straight seam pipe, 30-100% of the weld length and reduces the productivity of the same length. Thus, the minimum diameter of the pipe is mostly a straight continuous welding, the largest diameter spiral welded pipe.
